Last week on June 18 a U.S. Forest Service helitack crew conducted the agency’s first short-haul medevac. It occurred on the Trail Mountain Fire in central Utah when a firefighter suffered a leg injury. The location was very remote in steep terrain, which would have made it very difficult for firefighters to carry the victim out. The least hazardous option for extrication was helicopter short-haul in which personnel are carried as external cargo at the end of a rope. They can be flown to or extricated from a remote area.

One of the resources assigned to the fire was the Teton Interagency Helitack crew and helicopter, usually based on the Bridger-Teton National Forest in Wyoming.

Thankfully the injury to the firefighter was not life-threatening. After being flown to a nearby drop point and transported by ground ambulance, the person was treated at a hospital and released.

While the National Park Service has been conducting short-haul medevac extrications for years, the concept is fairly new to the Forest Service. The Teton Interagency crew first became qualified in 2015.

Four other Forest Service helitack modules are also qualified:

  • Wenatchee Helitack, Okanogan-Wenatchee National Forest, R-6;
  • Teton Interagency Helitack, Bridger-Teton National Forest, R-4;
  • Krassel Helitack, Payette National Forest, R-4;
  • Tucson Helitack, Coronado National Forest, R-3;
  • Central Montana Helitack, Helena/Lewis & Clark National Forest, R-1.

A National Park Service article has some of the history of interagency short-haul programs.

Kawak receives STC’s for new Chinook Internal firefighting tank

The tank can hold 2,500 gallons

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.

Having completed flight testing and received the STC, Billing’s Flying Service will be using the tank this summer.

Simplex introduces internal tank for Blackhawks

There are two versions, holding 850 or 1,000 gallons

For decades Simplex Aerospace has been manufacturing devices used by aerial firefighters, including the Helitorch and various internal and belly-mounted water tanks for helicopters. This year they added to the list by developing an internal water tank for Blackhawk helicopters. The 850-gallon tank can be installed in less than 15 minutes in several models of Sikorsky ships, including the S-70i, S-70A, UH-60A, and UH-60L.

According to the company, the 850-gallon tank drops water through the cargo hook well “with minimal modifications to the aircraft”. They also have a 1,000-gallon version with three dispersal doors, which requires “minimal modifications to the aircraft skin”.

While hovering, the tanks can be refilled at a rate of 1,000 gallons per minute, or on the ground using ports on either side. Pilots can select the number of drops, flow rate, and percentage of foam concentrate to be mixed with the water.  There is also an automatic emergency water drop feature.

Mark Zimmerman, Simplex’s CEO said “Simplex’s internal Fire Attack systems eliminate the need for the Blackhawk gear extensions required for belly mounted tanks, making the internal tanks ideally suited for civil Blackhawk operators.”

San Diego to get a new Sikorsky Firehawk

The City of San Diego Fire Department expects to receive their new Sikorsky Firehawk helicopter in October. Their staff just completed simulator and hands-on flight training for the new aircraft.

The only shade was under the Chinook at Sierra Vista

Jerry Messinger sent us this photo of N949CH, one of HeliMax’s CH-47’s at Sierra Vista, Arizona. He said it is on an exclusive use contract and has already flown about 75 hours on fires in the Southwest this spring. It is very dry there, he said.

Those large rotor blades can provide a little shade on a hot day.

The weather prediction for Sierra Vista today, 96 degrees, 6 percent RH, with southwest winds gusting to 27 mph. For Friday, Red Flag Warning with winds gusting to 45 mph. And zero percent chance of rain.

Washington DNR prepares helicopter fleet for wildfire season

The Washington Department of Natural Resources is getting their fleet of eight helicopters ready for the coming wildfire season. The agency began acquiring their military surplus UH-1H (B-205) ships in 1989.

The DNR started their helicopter program in the 1960’s with two Bell-47’s used for recon and carrying a 50-gallon water bucket which was designed by one of their pilots, Harold Clark. By the mid-1970’s the Kaman Husky, which could carry up to 450 gallons, replaced the Bell-47’s. Those six Kaman’s were phased out in the late 1970’s due to a shortage of spare rotor blades and the availability of the more reliable and faster Huey UH-1B, which were replaced by the UH-1H about 10 years later.

The agency now has a program manager, one helicopter coordinator, 11 U.S. Forest Service certified helicopter pilots, 6 aviation maintenance technicians (AMT) who maintain, and configure the aircraft, and one chief pilot who leads the team. Usually 7 helicopters are deployed, with one held in reserve as a spare.

All of the pilots have current Class II Medical Certificates and FAA Commercial Rotor Wing Certificates. Many maintain an FAA Certified Instrument Instructor rating and Airline Transport pilot certification.

In addition to the pilots and mechanics, the staffing includes one transportation supervisor, 7 helicopter managers, 7 squad leaders, 14 firefighters, and 8 support drivers. All helitack modules have an incident commander. Generally they stage at Omak, Deer Park, Dallesport, Pomeroy, Wenatchee, Colville and Olympia.

Below is an excerpt from an article at Spokesman.com:

The department pays for fuel, operations and maintenance, which works out to about $1,600 an hour when they fly.

Dropping water on forest fires can be rugged work. But while these “Hueys” are old – the most senior helicopter in the DNR fleet came off the factory line in 1963 and did two tours in Vietnam, where it was shot down twice – they’re extremely reliable and spare parts are plentiful.

34 Type 2 helicopters awarded contracts

The contract was effective April 6.

New exclusive use contracts have been awarded for 34 Type 2 firefighting helicopters. Announced by FedBizOps on April 6, the duration is for one base year through April 30, 2019, with the possibility of 3 one-year renewal option periods. The U.S. Forest Service has shown by how they manage the air tanker and Type 1 helicopter contracts that the option periods are definitely not a sure thing after cutting those aircraft during recent optional years.

All of the Type 2 helicopters are Bell products: 205, 210, and 212. The daily availability rates range from $5,500 to $8,800 while the hourly rates are $1,884 to $2,175.

The last Type 2 exclusive use contract awarded in December, 2013 for 31 helicopters also specified one base year with three optional years. The contract before that was for 33 helicopters.

The Forest Service also has helicopters on Call When Needed contracts, on the hope that they will be available when the phone rings. CWN aircraft, both fixed and rotor wing, cost more than exclusive use ships. For example, the 2017 average daily rate for large federal call when needed air tankers was 54 percent higher than aircraft on exclusive use contracts.
