Paul Filmer took some excellent photos of aircraft working on the Fern Lake Fire in Rocky Mountain National Park west of Estes Park, Colorado, December 4, 2012. The photo above is the first one I can remember seeing of an air tanker dropping with snow in the background.
We thank Paul for allowing us to use his photos. You can see a couple of dozen more that photos he took December 4 at his web site. More information about the Fern Lake Fire can be found at Wildfire Today.
The 26-second video above put together by Cy Kuckenbaker is a composite of the 70 planes that landed at San Diego International Airport during a four and a half hour period on November 23. It turns out, he explains, that with a blue sky background, it was not a huge challenge (for him) to superimpose video of all of the aircraft, placing many of them on the video screen at the same time. If I understand it correctly, the aircraft were shot on a beautiful, cloudless day, and time-lapse videos of the bridge and the clouds were added later.
It’s hard to explain… just do me a favor and watch it. 🙂
The mandatory availability periods for the nine large air tankers on national contracts ended in August, September, and October, but two P2Vs are still working today due the warm, dry weather that some areas of the country are experiencing. Tanker 48, operated by Minden, and Neptune’s Tanker 43 are the two that are working on a day by day basis through “optional use” provisions in their contracts, according to Jennifer Jones, a spokesperson for the U.S. Forest Service in Boise.
Air tankers were requested early Saturday morning, December 1, for the rapidly spreading Fern Lake Fire that was moving toward structures west of Estes Park, Colorado. Fire managers were told that the only large air tankers sill working were in California but were unavailable due to weather in the Bay Area, according to David Eaker, a spokesperson for the Fern Lake Fire.
Today two large air tankers were supposed to be parked on the ramp at JEFFCO air tanker base northwest of Denver after being ferried in from California, but only one made it, Tanker 48. The other one, Tanker 43 had to stop in Durango, Colorado, unable to climb over the continental divide due to weather. We’re thinking the old P2V does not have de-icing equipment.
If the USFS is going to keep air tankers working into the winter, maybe a better choice of which ones to keep on would be a couple of the BAe-146s, which I assume have de-icing equipment.
The one tanker at JEFFCO, 48, has not been used on the Fern Lake Fire yet due to strong winds over the fire. Mr. Eaker told Wildfire Today that they may be used very soon to pretreat some areas where large burnouts are planned, thanks to improving weather forecasts indicating decreasing winds.
The radar image above, 5 minutes before MAFFS #7 impacted the ground at 1738 local time, recorded a very large thunderstorm cell southwest of the crash site. The middle of the concentric circles is the location of the crash. The circles indicate 5, 10, and 15 nautical miles from the impact site. The light green areas may have been virga, rain that was not reaching the ground. The red, light brown, dark green, and possibly the yellow areas were most likely rain, accompanied by strong winds. The longest east-west line is the South Dakota/Nebraska state line. The longest north-south line is the boundary between Wyoming and the states of South Dakota and Nebraska.
In addition to the C-130 working on the fire, there was also a Bureau of Land Management Air Supervision Module aircraft which was flown by a lead plane pilot and also carried an Air Tactical Group Supervisor. It was acting as the lead plane at the time of the accident.
The ASM/Lead experienced a severe downdraft while approaching the intended retardant drop zone with the C130 in trail. This is being investigated by the US Forest Service as a separate Incident With Potential.
The third fixed wing aircraft to arrive at the White Draw fire that was mentioned in the report served as Air Attack. It was piloted from the left seat by Air Attack 3 (AA3 in the report), and in the right seat was the Air Tactical Group Supervisor. Both were employed by the State of South Dakota.
Before the crash, the air attack aircraft encountered sudden updrafts and downdrafts with airspeed fluctuations between 20 to 40 knots, which forced the aircraft into bank angles of approximately 90 degrees.
Here are some interesting passages from the report that discuss the weather conditions:
At 17:38:18L, MP1 ordered an e-dump of the retardant, which was immediately conducted. At the same time, Firefighter 1 (FF1) a ground firefighter, was located approximately 1.5 miles west-southwest of the future mishap site. FF1 witnessed the MA [mishap aircraft] jettison their retardant load, at which time she experienced variable surface winds with estimated gusts up to 50 miles per hour. At the same time, in Air Attack, ATGS observed the smoke lying down and “sheeting” of the fire, indicating to him “hellacious” surface winds. ATGS and AA3 lost altitude, experienced updrafts and downdrafts with airspeed fluctuations of 20 to 40 KIAS and severe turbulence. Air Attack lost an estimated 1,000 ft due to the weather conditions. ATGS did not see the MA jettison the retardant load.
Between 1730L and 1745L, Incident Commander 1 (IC1), a member of the Army National Guard, was traveling on a motorcycle, southbound on Highway 18 approximately seven miles north of Edgemont attempting to get to an 1800L meeting at the White Draw Fire incident command center in Edgemont, South Dakota. While heading towards Edgemont, IC1 witnessed the MA flying to his right, approximately one mile away, making a bank as the MA prepared for their approach to the drop area. IC1 lost sight of the MA while going down the hill towards Edgemont, at that same instant, IC1 was “hit with this extreme, fierce wind”. IC1 described it as side wind because it “pushed me over to the other side of the highway”.
The MAFFS crew received a briefing on the weather for the Arapahoe fire they dropped on earlier in Wyoming, but they did not have any specific weather information on the weather for the White Draw fire in southwest South Dakota and no update was requested when they were diverted to that fire.
From the report:
On 1 July 2012 at 1650L, the National Weather Service issued a severe thunderstorm watch for northeast Wyoming and western South Dakota encompassing the area surrounding Edgemont, South Dakota and the White Draw Fire. The severe thunderstorm watch, valid from 1650L to 2300L, was issued for potential hail up to two inches in diameter and wind gusts up to 70 miles per hour. However, there was no evidence the MC requested or received forecast weather information for South Dakota or the White Draw Fire area at any time on 1 July 2012.
After dropping on the Arapahoe fire in Wyoming, the MAFFS was dispatched to the Highlands fire west of Custer, South Dakota. But en route they were diverted to the White Draw Fire which was 24 miles southeast of the Highlands Fire.
At that time I was taking photos at the Highlands Fire and the Oil Creek Fire, the latter being farther west across the state line near Newcastle, Wyoming. Between 1730 and 1830 I remember seeing massive, very dark thunderstorm clouds to my southeast. The photo below taken at 1715 is looking south toward the Highlands Fire. In the background the dark clouds farther south can be seen.
From 1630 until 1645 a Canadian “Bird Dog” and a CV-540 were over the Highlands fire. They were asked to drop, but refused, saying there were too many people on the ground in the intended drop area. It would be interesting to know where they went after being released from that fire, or if the weather affected the decision about their destination.
The MAFFS has a capacity of 3,000 gallons, but each time MAFFS #7 reloaded that day they refilled with less retardant. At the White Draw fire it was only carrying 2,346 gallons which it split into two drops on the fire.
Crew rest or fatigue were not issues, according to the report.
Regarding the radio transmissions from the lead plane pilot saying “I got to go around” after encountering the downdraft and coming within 10 feet of the ground, and a few seconds later calmly advising the MAFFS to “drop your load when you can”, (meaning an emergency release of retardant to lighten the load, enabling the aircraft to more easily maneuver) the report said:
MAFFS aircrew members attested that a call for a go around is most commonly heard regarding misalignments for drops rather than urgent situations. It is possible that [the lead plane’s] call for a go around while meant to abort the mishap drop, was not interpreted by the [MAFFS Crew] as significantly urgent, based on their prior experience.
According to the report the overall flying experience of the MAFFS crew was high.
However [the pilot, the aircraft commander] had limited experience as a MAFFS aircraft commander and [the navigator] was participating in his first MAFFS mission. [The pilot] was a current and qualified Senior Pilot with over 1,900 total C-130 hours, however prior to the day of the mishap he had accomplished only seven drops as a MAFFS copilot and zero drops as a MAFFS aircraft commander.
The second pilot was more experienced with MAFFS and served as a MAFFS instructor pilot for this sortie.
The emergency locator transmitter (ELT) failed to activate when the C-130 crashed. One of the survivors called 911 on his cell phone and reported the crash but he said he didn’t know where he was.
The flight data recorder for the C-130 was found and shipped to the Air Force Safety Center for data retrieval and analysis. The report said the last 12.8 hours of data on the device were corrupt and unusable for investigation purposes.
There was no evidence that aircraft weight or the MAFFS unit in the cargo hold were factors in the crash. “Prior to the mishap, the MAFFS unit was operating at 100 percent capability and an emergency dump was successfully completed.”
About 34 minutes after the crash, firefighting helicopter crews assigned to the fire that were on the ground at the nearby Edgemont Municipal Airport were notified about the crash. But they were unable to fly at that time due to heavy rain, gusty winds, and a low ceiling. While waiting, an EMT loaded medical equipment on N935CH, call sign 5CH.
At the time of the crash the air attack ship was at 1,500 feet above the ground and following the MAFFS aircraft, observing the drop. On that pass the air attack ship had their hands full, experiencing extreme turbulence which resulted in bank angles of approximately 90 degrees. After the crash it had to leave the area due to the strong turbulence and the approaching thunderstorm. It loitered at a safe distance for about 30 minutes before it was able to access the area again, after which it led one of the fire’s helicopters, H-535, to the site.
During the last pass, the lead plane over-temped (or “smoked”) the aircraft engines while attempting to recover from being pushed down to within 10 feet of the ground and had to go to the Rapid City Airport.
When the weather improved, the two helicopters, N911FS, call sign H-535 (from the San Bernardino National Forest in southern California), and 5CH, departed and proceeded toward the mishap site. When they landed at the site at approximately 1850, the EMT on 5CH met the survivor who was still talking to the 911 operator on his cell phone. The EMT assessed and began treating him while the other helicopter crewmembers searched for other survivors, eventually finding the second survivor “wandering near the mishap site”. Helicopter 5CH transported both survivors to the Custer Airport, about 10 minutes away. One of them was then flown by an emergency medical helicopter to Rapid City while the other went by ground ambulance to a hospital.
As Wildfire Today reported on September 17, the pilot and at least two crewmembers of H-535 were given awards for their actions related to the crash. It is possible that others involved in the emergency response to the incident also received awards.
Today the US Air Force released the full report on the crash of MAFFS #7, the C-130 air tanker operated by the North Carolina National Guard. The accident occurred July 1, 2012 as the aircraft was attempting to drop retardant on the White Draw Fire near Edgemont, South Dakota. There were four fatalities. The two crewmen in the rear of the aircraft were seriously injured but survived. Those two were operating the Modular Airborne FireFighting System (MAFFS) in the cargo hold which enables the C-130 to function as an air tanker, capable of dropping up to 3,000 gallons of fire retardant.
The investigation was led by Brigadier General Randall C. Guthrie, USAFR. Also participating were the following board members: Legal Advisor, Medical Member, Pilot Member, Maintenance Member, Flight Engineer Member, Weather Member, Loadmaster Member, Recorder and two Court Reporters.
The report does not list who the investigation board may have interviewed. Most likely they talked with the crews of the lead plane and air attack and probably other personnel assigned to the fire in various positions, but it would seem to be important to have someone on the board who lives and breathes aerial firefighting. Maybe the “Pilot Member” was MAFFS qualified at least.
We will be writing more about this report in the coming days, but for now, here is the “Opinion Summary” from the report:
I find by clear and convincing evidence the cause of the mishap was Mishap Pilot 1 (MP1), Mishap Pilot 2 (MP2), Mishap Navigator (MN) and Mishap Flight Engineer’s (ME) inadequate assessment of operational conditions, resulting in the MA impacting the ground after flying into a microburst. Additionally, I find by the preponderance of evidence, the failure of the White Draw Fire Lead Plane aircrew and Air Attack aircrew to communicate critical operational information; and conflicting operational guidance concerning thunderstorm avoidance, substantially contributed to the mishap.
On 1 July 2012, at approximately 1738 Local time (L), a C-130H3, T/N 93-1458, assigned to the 145th Airlift Wing, North Carolina Air National Guard, Charlotte Douglas International Airport (KCLT), Charlotte, North Carolina, crashed on public land controlled by the United States Forest Service (USFS), while conducting wildland firefighting operations near Edgemont, South Dakota.
At the time of the mishap all members of the Mishap Crew (MC) were assigned or attached to the 156th Airlift Squadron, based at KCLT. The MC consisted of MP1, MP2, MN, ME, Mishap Loadmaster 1 (ML1) and Mishap Loadmaster 2 (ML2). For the mishap sortie, MP1 was the aircraft commander and pilot flying in the left seat. MP2 was in the right seat as the instructor pilot. MN occupied the navigator station on the right side of the flight deck behind MP2. ME was seated in the flight engineer seat located between MP1 and MP2, immediately aft of the center flight console. ML1 and ML2 were seated on the MAFFS unit, near the right paratroop door. ML1 occupied the aft Modular Airborne Fire Fighting System (MAFFS) control station seat and ML2 occupied the forward MAFFS observer station seat.
After three uneventful sorties, the Mishap Aircraft (MA) entered the White Draw Fire Traffic Area (FTA) in South Dakota. The lead plane for the MA was Lead B-5. Lead planes are responsible for the safe, effective and efficient use of air tanker operations within an FTA. A lead plane is also responsible for leading air tankers to a low-level, where fire retardant can be safely dispensed. Air Tactical Pilot (ATP) piloted Lead B-5 from the left seat and Air Tactical Supervisor (ATS) occupied the right seat. ATS initially acted as the airspace manager for the White Draw FTA. However, prior to conducting the retardant drops a third aircraft, Air Attack, entered the White Draw FTA and took over airspace management duties. Air Attack 3 (AA3) piloted Air Attack from the left seat and Air Tactical Group Supervisor (ATGS) was in the right seat.
Upon entering the FTA, the MC noticed a thunderstorm and witnessed lightning between 10 and 20 nautical miles away. ATP determined two retardant drops were needed. Lead B-5 and the MA performed the first drop precisely on target, but the MA’s airspeed was 10 knots slower than planned. As the MA positioned for the second drop, ME and MN noticed an increase in fire activity and surface winds changing in both velocity and direction. Lead B-5 then experienced a rapid “sinker” and ATP stated, “I got to go around.” ATP struggled to keep Lead B-5 under control. In response, MP2 commanded a go-around “out of this” and MP1 pushed the throttles up. Twelve seconds later, ATP advised the MC to dump their load and the MC complied. Despite MA engines at maximum power, airspeed and altitude continued to deteriorate, ultimately resulting in the mishap. The MA impacted lightly-wooded, rolling terrain and slid through a tree-lined ravine which was approximately eight feet deep, before stopping roughly 410 feet (ft) from the initial point of ground impact. MP1, MP2, MN and ME died in the mishap. ML1 and ML2 survived, but suffered significant injuries.
The mishap aircraft (MA) and a USFS-owned MAFFS unit were destroyed. The monetary loss is valued at $43,453,295, which includes an estimated $150,000 in post aircraft removal and site environmental cleanup costs. There were no additional fatalities, injuries or damage to other government or civilian property.
Neptune Aviation Services will retire the first two of its seven operational P2V Neptunes by the start of the 2013 wildfire season, as the aerial firefighter phases in its growing fleet of former commercial jets, modified as air tankers.
The Missoula-based company, which has been operating the specially configured BAe 146 jets since 2011, currently has three, with two more slated to enter the fleet during the first half of 2013. The four-engine jets, all relatively low-cycle, were procured from airlines and leasing companies to replace Neptune Aviation’s former US Navy Neptune patrol aircraft. The twin-piston engine powered P2Vs, dating from the early Cold War Era, had been retrofitted with tanks for fire retardant chemical dropping following their retirement from military service.
“The BAe 146, which we selected as our next-generation air tanker, has at least 20 years of service ahead of it as an aerial firefighter,” said Neptune Aviation President Dan Snyder. “As we take delivery of additional aircraft, we will continue to retire our remaining P2Vs at the rate of about two per year, depending upon the needs of the US Forest Service.”
Snyder added that Neptune Aviation Services is currently in discussions with TronosJet Maintenance for the acquisition of a sixth BAe 146. The Prince Edward Island company has partnered with Neptune on the BAe 146 modifications, which includes the installation of an internal tank with a capacity of 3,000 gallons of fire retardant. Long term, the operator plans to fly as many as 11 modified BAe 146s. In a related development, Neptune Aviation Services, according to Snyder, has taken the lead on the BAe 146 Air Tanker Modification Project from Tronosjet.
“Most of the modification and engineering work has shifted to Neptune Aviation Services, which includes all of the revisions made to the initial modification work,” he explained. “The revisions were based on our operational experience with the aircraft and will improve the performance of the tank system.” Going forward, Snyder added, TronosJet Maintenance will be responsible for procuring the aircraft, as well as technical support.
Currently, eight of the company’s P2V pilots have been trained on the BAe 146 airtanker, while another four are going through the ground school at Neptune Aviation Services in Missoula. The ground school is being directed by a former Air Wisconsin instructor pilot.
“The simulator portion of training is conducted at Oxford Training Academy in the UK,” Snyder explained. “The pilots get a BAe 146 type rating, following a successful check ride in the airplane with a Neptune examiner pilot.”
An organization that represents some of the companies that provide firefighting helicopters and air tankers to the government has issued a press release explaining how the looming “fiscal cliff”, which Wildfire Today wrote about in October, might affect the availability of aerial resources in the suppression of wildfires:
The aerial firefighting industry is citing the risk of significant cutbacks in its ability to respond to wildland fires, if automatic Federal spending cuts become effective at year end.
“Should Congress and the Administration fail to reach a deficit reduction agreement, our fear is that funding for forest protection will be severely reduced, making it that much more difficult for some of our members to maintain the assets and manpower needed for wildland firefighting,” said Tom Eversole, Executive Director of the American Helicopter Services and Aerial Firefighting Association (AHSAFA) in Washington. “The possibility of going over the fiscal cliff is a major concern of our members.”
Todd Petersen, Vice President Marketing, for Portland, Oregon-based Columbia Helicopters, warned that if Congress and the administration are unable to resolve their differences over cutting the deficit, it could lead to cutbacks in the number–and duration of– exclusive use agreements with the US Forest Service (USFS), as well as call when needed contracts. Exclusive use contracts, Peterson explained, are a bread and butter item, usually running anywhere from 90 to 180 days per year–per aircraft. Normally, they are in effect over four years, based on three, one-year renewable options after the first year.
“If the contracts are cut, it could mean that we would have to take some of the helicopters that we have used for firefighting and redeploy them to other kinds of jobs,” Petersen noted. “Those helicopters and crews would no longer be available for firefighting, if they were needed.”
Stuart Taft, Chief Pilot for Lewiston, Idaho-based Hillcrest Aircraft Company, echoed this concern. “For us, the big question is whether the USFS would be forced to cut some of its exclusive use contracts, and rely more on call when needed aircraft in the event of a major wildfire,” he said. “We will have the opportunity to discuss this with the USFS at a meeting with the agency in Boise, Idaho, at the end of this month, and hopefully, we’ll get a clearer picture of what they might do.” A major issue, said Taft, is whether there will be immediate, across the board cuts by the Forest Service, or whether they would defer cuts to certain programs to a later date. “It’s very difficult to predict what might happen,” he remarked.
Taft pointed out that since the USFS is a major Hillcrest Aircraft Company customer, any contract funding reductions directly impacting the operator will mandate scaling back on staffing levels, as well as purchases from vendors. “If we fly less, we will not buy as much fuel; and we won’t have to purchase as many repair parts. It could have a very big impact on a lot of operators and vendors.”
At Intermountain Helicopter in Sonora, California, Chief Pilot Pete Gookin, stated that budget cutbacks could cause the government to consider greater use of military assets for wildland fire protection.
“It’s only my opinion, but in an effort to appear that it’s saving money, the government could try to replace at least some of the private contractors with the military,” Gookin said. “While that might look good to the taxpayers, military crews are (generally) not trained to fight fires, and their aircraft were not designed to be used for firefighting as their primary mission. Aerial firefighting was designed by civilian operators working with the US Forest Service, over the past 40 years. It’s a civilian operation and it should stay that way.”
Columbia Helicopters, Hillcrest Aircraft Company, and Intermountain Helicopter are members of the American Helicopter Services and Aerial Firefighting Association (AHSAFA), the Washington-based trade association representing the commercial operators of helicopters and fixed wing aircraft engaged in aerial wildland firefighting.
The video below which shows dozens of air tanker drops is very interesting. Most of the video was shot from a lead plane, with views rarely seen by most of us. The technical quality of the video is not great — low resolution and a little shaky — but it’s very worth viewing. Occasionally you can see the smoke generated by a BLM lead plane which marks the target for the air tanker.
Some of the aircraft include: P-3, P2V, S2T, DC-10, C-130 MAFFS, and an air tanker that is very rarely seen, Evergreen’s 747.
