Here is an excerpt of what happened after the Pilot in Command shut down the engines:
…Two of the crew’s mechanics climbed on top of the aircraft to complete their tasks. These tasks include, but are not limited to, visually checking certain fluid levels within a five minute window for the most accurate readings. As the crew members were busy at work and focused on their assigned tasks, the PIC began going through the engine start-up process to see if the error code issue was completely resolved.
Upon hearing the engine spool up, the crew chief immediately wanted eyes on top of the aircraft, knowing that there might be crew personnel engaged on top. Two crew mechanics were indeed on top of the aircraft, aft of the front rotor. Hearing the engines spool up, several support personnel noticed these two mechanics and began yelling: “Get down! Get down!” As the engine was spooling up and the rotors began to turn, one of the mechanic crew members was struck in the head, impacting the side of this individual’s face/head and their safety helmet. The crewmember immediately went limp and slumped down.
The second crewmember was able to grab the struck mechanic in a bear hug to prevent them both from falling off the aircraft. Crewmember 2 stated that he “fundamentally supported and slid partway down the aircraft and then pushed off the fuel tank near the bottom.” He explained that this response was based on his military training. Crewmember 2, still supporting the injured mechanic, fell onto the pavement—both landing safely. At this point, the injured mechanic sat up, stunned. Simultaneously, the PIC heard the noise outside the aircraft and immediately initiated complete engine shut-down…
After being checked by a paramedic at the helibase, the injured crewmember was driven to a hospital by a company driver to be examined. The individual was treated and released from the hospital the same afternoon.
Following the accident and before any other flight operations continued, the crew had a “safety stand-down”. This provided the crew with an opportunity to establish a clear understanding of what happened, how operations will continue moving forward, and closure for anyone who may have been traumatically affected by the incident.
Discussions within the company after the incident centered on safety meetings, communications, and continuing the use of helmets.

Kawak Aviation has received FAA Supplemental Type Certification (STC) for its CH-47D Chinook aerial liquid delivery system (ALDS) and auxiliary hydraulic system. The 2,500-US gallon (9,463-liter) tank fills in under 40 seconds and can release a full load of water in 3 seconds. The system is built around a fully independent 50hp hydraulic system, a new refill pump, and unique design of the water tank door.
Using their existing refill pump technology as a starting point, they designed an all new pump to meet the fill time requirements of the new system.
“Unlike swinging door designs, our sliding doors provide an unbroken ribbon of water that exits the tank with less wind break up providing a better drop pattern. In short more water reaches the fire for a more effective drop,” said Andrew Sawyer, director of marketing.
The system includes a secondary 128-US gallon tank that can add foam concentrate if needed as the main tank is filled. A live telemetry functionality automatically records how much water is taken on, how much is dropped, and where. This information is then transmitted to the agency managing the fire to assist in analyzing utilization of resources.
After I visited Airstrike’s hanger last week to check on the progress on their P3, Tanker 23, I stopped by the Helimax Aviation facility just down the road. Two of their CH-47D Chinooks were undergoing maintenance in the hangar.
Helimax has two Chinooks on Forest Service exclusive use contracts and two on call when needed contracts, plus two others. Their mandatory availability period begins in early May for the EU ships. Upon mobilization they travel with two pilots, a non-rated crewmember, four mechanics, and one fuel truck driver hauling up to 6,000 gallons. As shown in one of the photos below they also load into the cargo bay a four-wheeler with an attached trailer for hauling the 2,600-gallon Bambi Bucket. The Chinook can cruise at 140 knots (161 mph), pretty fast for a helicopter, and has an endurance of about three hours.

While some have said the National Interagency Fire Center responded slowly to the very busy wildfire activity that started March 6 in the central plains where about a million acres burned in a few days, eventually they did take action.
In an effort to mobilize a Type 1 helicopter they contacted Columbia Helicopters who had one on display at a helicopter convention.
“This is the first time we have received a resource order for firefighting duty, while displaying our helicopter at a convention,” said Keith Saylor, Director, Commercial Operations, for the Portland, Oregon-based company. Reached by phone at the Helicopter Association International (HAI) convention in Dallas, Saylor explained that transitioning the helicopter, from a static display to a mission-ready firefighting aircraft, involved removing the rotor blades, exiting the convention center, then reinstalling the rotor blades. This was followed by a flight to a nearby airport for refueling and overnighting. Called up on March 9, the helicopter was deployed the following day to Ardmore, Oklahoma, under an optional use clause of a US Forest Service (USFS) exclusive use contract. The helicopter was dispatched with two pilots, five mechanics and ground support equipment drivers.
A former US Army-operated CH47D Chinook, the helicopter was modified by Columbia Helicopters with a 2,800 gallon capacity internal tank for water, jells, foam, or retardant dropping, and had been flown to the convention following firefighting duty on East Coast fires.
Also responding to the fires, Neptune Aviation Services dispatched three of its BAe-146 air tankers to multiple locations, according to Dan Snyder, Chief Operating Officer for the Missoula, Montana-headquartered company. Three of the tankers were dispatched from Missoula between March 9 and 11, and flown to USFS tanker bases in Ardmore, Oklahoma, Abilene, Texas, and the Rocky Mountain Regional Airport, near Denver, Colorado. A fourth BAe 146 tanker will continue to fly out of a base at Lake City, Florida, where it has been on duty since February 20.
On March 16 Neptune mobilized T-05, the first of their P2V piston engine tankers to start an assignment this year, which will probably be the model’s last season as the company completes their transition to the jet-powered BAe-146 airframe.

On Friday Billings Flying Service unveiled their new 24,000 square-foot hangar and maintenance facility near the airport in Billings, Montana (map). It has enough room for four to five of their Chinook helicopters, depending on if rotors are installed on the aircraft.
The company has at least six Chinooks and in 2014 became the first non-military owner of CH-47D’s when they purchased two from the U.S. government. Gary Blain, a co-owner of the company, and another pilot flew the two helicopters from the Redstone Arsenal in Huntsville, Alabama to the company’s facilities south of Billings, Montana near the Yellowstone River.
Anything you do with aircraft is expensive. Mr. Blain told us at the time that they spent $32,000 for fuel during their two-day trip, with an overnight stopover in Norfolk, Nebraska.
Sky Aviation purchased four CH-46 helicopters in 2015.
Alyssa Gaulke of Sky Aviation sent us some photos of one of their CH-46E that is assigned on the Lava Mountain Fire 17 air miles northwest of Dubois, Wyoming — and we found more at their Facebook page.
This CH-46E is one of four that the Worland, Wyoming-based company acquired last year.
