A video of a DC-10 air tanker dropping on a fire in Washington, August, 2013.
Tony Duprey uploaded this video to YouTube August 11, 2013. His description
T-911, Jojo fire, Yakima Agency, Wa. Coverage level 3, start stop. This is the 2nd split .. 8000 gallons. With Lead 41 – (great job). Dozers were able to walk through the black and build dozer line in the retardant..Nice job fella’s!! Total team effort.
Be sure you watch the last few seconds, showing where the retardant landed.
An S-2 air tanker working on the Clover fire southwest of Redding, California experienced a problem that caused the pilot to have to shut down one of the two engines. It occurred while the aircraft was returning to Chico to reload with retardant. The pilot landed the aircraft safely at Chico according to the Willits News.
Last month Tanker 910, a DC-10, lost their #2 engine just after making a drop on the Beaver Creek Fire in Idaho. They also landed safely, but at Pocotello, Idaho, their reload base.
DC-10 photos on the Morgan Fire
Claycord has three excellent photos of one of the DC-10s (or both of them?) dropping on Mt. Diablo during the Morgan Fire 18 miles east of Berkeley, California. When you visit the site, click on the photos to see larger versions. Both of the DC-10s responded to the fire but soon thereafter were diverted to the Clover Fire near Redding, California which was threatening numerous structures.
Mike McMillan took these photos of aircraft working on the Rim Fire in California on August 29, 2013 for the U.S. Forest Service. Earlier we posted some photos of UH-60 Blackhawks and HH-60 Pave Hawks arriving at Columbia Airport to be used on the fire.
Below are two videos posted by J N Perlot showing the DC-10 dropping on the Rim Fire. In the first one, on August 24, the approach to the drop begins at about 1:50.
In the next video, shot on August 31, the approach to the drop begins at about 1:00.
For a decade or two CAL FIRE and U.S. Forest Service aviation managers been talking off and on with officials at the Castle Airport (MER), 8 miles northwest of Merced, California, about using it as an air tanker base. As a former Air Force base with an 11,802-foot runway, and its location in central California near the Sierra Nevada Mountains, it could be a valuable resource for any fire aviation asset, but especially for Very Large Air Tankers like the DC-10 or 747.
Finally, prompted in part by the nearby Rim Fire, 40 miles from the airport, the U.S. Forest Service recently signed an agreement with Merced County to allow the airport to be used as an air tanker base. Tuesday of this week both DC-10 air tankers began using it to reload with retardant, making the round trip to and from the Rim Fire every 30 to 40 minutes, dropping 11,600 gallons with every trip.
According to the Modesto Bee:
Under the agreement, Merced County will charge the Forest Service through a series of fees: $225 per month for the 5,200-square-foot building lease, $450 per day for the 551,600-square-foot ramp and 50 cents per 1,000 pounds a plane weighs upon landing, according to county staff.
With a DC-10 air tanker weighing about 368,000 pounds, it will cost around $184 for each landing. The fee for landing a 6,505-pound single-engine Air Tractor AT-802 with an 820-gallon retardant capacity would be about $3.
For now, at least, the Tanker Base will be on call when needed status, staffed only if there is a specific need.
The video below has information about this new use for the Castle Airport.
It’s just a guess, but what you see in this photo of Tanker 910 over the Beaver Fire in Idaho may be evidence of what led to the replacement of the number two engine last week. The image is a screen grab from the video below which has many excellent still images from the Beaver Creek Fire.
As we move into national Preparedness Level 5 today for the first time since 2008, and we have more than 48 uncontained large fires, it’s a good time to see what air tankers are available. These numbers are provided by Mike Ferris, spokesperson for the U.S. Forest Service.
Today, not counting 2 air tankers that are on their days off and five that are down for maintenance, there are 13 in service.
Overall, if none were on days off or down for maintenance, we would have:
7 P2Vs on Exclusive Use Contract
2 BAe-146s on Exclusive Use Contract
2 DC-10s on Exclusive Use Contract
4 CV-580s borrowed from Canada and Alaska
5 MAFFS borrowed from the military
This amounts to 11 that are on federal contract and 9 that are borrowed, for a total of 20.
Six of the seven air tankers that received “next generation” contracts, and the 747 that will be under a CWN contract, are weeks or months away from being physically ready and fully certified. However, these are counted when the USFS distributes misleading stats claiming, “Overall, we could have up to 26 airtankers available for wildfire suppression.”
Tanker 910, a DC-10 Very Large Air Tanker, experienced an engine failure coming off of a drop on the Beaver Creek Fire in Idaho on Thursday, August 15. The pilots flew the tanker back to their reload base at Pocotello, Idaho, making a non-emergency landing, said Rick Hatton, CEO of 10 Tanker Air Carrier. The engine, the number two engine which is in the tail, is being replaced and the aircraft should be back in service today or Monday.
Losing an engine is not unheard of, especially in the P2Vs air tankers which have 16 18-cylinder radial engines with many moving parts. For example in 2012 there were two engine failures in a two day period. One occurred in a P2V just after takeoff from Rapid City. Tanker 43 had to jettison their retardant onto the runway, which required its’ closure, diverting at least one commercial flight to another airport.
10 Tanker’s two DC-10s have both been very busy on fires for the last couple of months. Tanker 911 received a multi-year exclusive use contract on June 7 during the next generation award process. Mr. Hatton told us that on June 14 their other DC-10, Tanker 910, received a 60-day exclusive use contract. We had been told by a spokesperson for the U.S. Forest Service that it was a Call When Needed contract like the one awarded to Evergreen’s 747 on June 14. Mr. Hatton said that at the end of the 60 day period the contract will revert to CWN for Tanker 910. He, of course, is bullish on the capability of the DC-10s, and said:
Any future national fleet composition would be significantly enhanced across all the relevant metrics by having six to nine Next Gen DC-10s on long term exclusive use contracts.
An Air Tactical Group Supervisor (ATGS) has completed a detailed comparison of the use of a DC-10 Very Large Air Tanker (VLAT) and P2V Large Air Tankers to complete the same task of creating 4.6 miles of retardant line on the Colockum Tarps Fire, which is what Tanker 911, a DC-10, accomplished during 3.12 flight hours on July 30, 2013.
The DC-10 made eleven drops from five-11,600 gallon loads of retardant. The writer figured it would take 41 drops from P2Vs to construct the same amount of retardant line. Two P2Vs could do it in two days, or four P2Vs could do it one day. Depending on which scenario was used, a DC-10 would result in a cost savings of $122,078 or $136,578.
Other advantages pointed out were that the VLAT could accomplish the objective much more quickly with a wider and more consistent retardant line, and “the eleven individual drops with the VLAT significantly reduced the number of ‘pilot drop exposures’ as compared to the number of drops/passes that would have been required with heavy airtankers”.
The DC-10 was tied up for just over three hours, but it would have taken four aircraft-days if P2Vs were used. The VLAT freed up air tankers, ASM/Bravos, and lead planes for other fires. If we had 44 air tankers like we did in 2002, that would not be as critical as the present situation, where we only have about 10 large air tankers plus one VLAT on exclusive use contracts, and one VLAT on a call when needed contract.
The 747 VLAT may become available by the end of September on a call when needed contract and we may have one or two “next generation” large air tankers in the fleet within the next few weeks.
