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.

Here are a few notes that I scribbled in a notebook at the Aerial Firefighting conference in Sacramento this week. This is Part One — I will post Part Two later.
Mike Schoenau, an Air Tractor dealer out of Tulare, CA, said a new single engine air tanker is being flight tested now. The model name is AT-1002 and will hold up to 1,000 gallons. You will be able to purchase one for yourself for about $2.5 Million.
The Bureau of Land Management has not released their list of SEATs on contract this year, many of which will be the amphibious Fire Boss, a variant of the Air Tractor 802. Fire Boss doesn’t know if they will be converting the new AT-1002 1,000-gallon SEAT to use floats.
Their fourth converted DC-10, Tanker 914, will be ready to fight fire this summer. Rick Hatton, the President and CEO of 10 Tanker Air Carrier, said their approval by the Interagency Airtanker Board came to the end of its six-year term, so they retook the grid test in December. Their three DC-10s averaged about 300 hours on fires in 2017, which is more than usual.
I got into a long detailed conversation with Mr. Hatton about how their retardant delivery system can maintain a constant flow, adjusting for the amount of retardant in the tank, drop height, and speed. It usually drops at 150 knots and 200 feet.
Hours per CL-415
As we reported yesterday, Shawna Legarza, the USFS Director of Fire and Aviation, said the two CL-415 scooping air tankers that were on USFS contract in 2017 each had over 400 hours of fire flight time. Due to a reduction in the firefighting budget, the two scoopers had to be cut this year from the exclusive use list. At least a couple are still on a CWN contract, but they may or may not be available if the USFS Calls them When Needed.
Keith Saylor, Columbia’s Director of Commercial Operations, said the company will have three Type 1 helicopters, CH-47 Chinooks, on exclusive use contract this year. Two have internal tanks and one will use an external bucket.
Shawn Bethel, Conair’s Director, International Business Development, said the external tank on the Q400 can be removed in about three hours by 9 to 12 workers. They recently received a contract to supply six Q400’s to France’s Securite Civile (Department of Civil Defense and Emergency Preparedness).
The Q400 MR can carry up to 10,000 liters (2,600 gallons) of water or retardant. In addition to the nine S-2’s and two Q-400’s, France also has twelve CL-415’s and 40 helicopters.

One of Helimax’s CH-47D’s has been shipped to Australia and will be working for the New South Wales Rural Fire Service during their summer bushfire season.
According to the Wollondilly Advertiser, which has photos and more information, it will be working out of Camden, NSW southwest of Sydney (map) using an external water bucket carrying about 2,000 gallons.
An aircraft resembling the Chinook was spotted in a shipping box it shared with one of Coulson’s S-61’s in a photo posted November 3, 2017 by Coulson.
The video below from the Wollondilly Advertiser, shows the Chinook taking off near Camden, NSW.

The last time we wrote about the 2,800-gallon internal water tank for Columbia Helicopters CH-47D Chinooks was April 6, 2016 as Simplex was developing the system soon after they had been granted a supplemental type certificate by the FAA. The tank can be filled in 60 seconds using a pump on a 12-foot-long 10-inch hose. Foam concentrate can be added to the water from a 140-gallon reservoir. The water tank can be rolled onto the helicopter and attached with four bolts. Multiple drops can be selected by the pilot and it has an emergency drop feature.
The tanks were fully operational during the 2016 wildfire season and were used by two of Columbia’s CH-47D’s for a total of 740 hours.
One of their ships was on display during the HAI HELI-EXPO conference in Dallas earlier in March. Thanks go out to Mark Johnson at Columbia for the photo and videos.
When the National Interagency Fire Center started mobilizing aircraft to the central plains after a million acres burned in Kansas and Oklahoma, they dispatched the helicopter you see in the photo above while it was at the conference.
Keith Saylor, Director, Commercial Operations, for Columbia 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 with two pilots, five mechanics and ground support equipment drivers.
The video below shows one of the CH-47D’s making a water drop.
The next video is a Columbia promotional video, but it has some brief interior shots of the internal tank system.

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.
As we told you on December 21, Jordan Aircraft Services is constructing internal tanks for the Boeing CH-47 Chinook helicopter. With the horizontal configuration of the tank, 54-inch pistons at each end will push the water toward the valve in the center in order to maintain adequate head pressure and a constant flow. The tanks, designed by Eric Foy of Perideo LLC, will hold up to 2,800 gallons.
Tony Cabler, the Quality Director for Jordan Aircraft Service, sent us these photos he took, explaining that the tanks are far from being ready to use.
The personnel at Jordan Aircraft Services have been involved in constructing tanks for a number of aircraft, including S-61 Sea King helicopter, 10 Tanker’s DC-10, Erickson’s Air-Cranes and MD-87s.
A company in Central Point Oregon is developing an internal tank for the Boeing CH-47 Chinook helicopter. Jordan Aircraft Services is constructing a tank engineered by Eric Foy of Perideo LLC in Rogue Valley Oregon that will hold up to 2,800 gallons.
It will employ an innovative method to help produce a constant flow of water or retardant, according to Ed Jordan, owner of Jordan Aircraft Services. Since the tank system is primarily horizontal in the aircraft, it could be difficult to maintain adequate head pressure at the bottom of the tank as it empties using gravity rather than a pressurized system. As the water is dispensed through a valve in the belly of the Chinook, horizontally mounted 54-inch pistons will push the liquid toward the center of the tank over the valve. This is intended to maintain an adequate head pressure ensuring that the desired flow rate is obtained.
Mr. Jordan told us that the tank itself is completed, but they are still working on the valve system. The tank has been installed in a Chinook in Medford, Oregon operated by CHI Aviation, formerly known as Construction Helicopters. They expect to be able to begin testing by early Spring.

On a related note, Billings Flying Service now has six Chinooks. The company began acquiring them from the military in 2014 when they purchased two which they flew back to Billings from the Redstone Arsenal in Huntsville, Alabama. The ships were busy in 2015, Gary Blain, a co-owner of the company, told Fire Aviation. He said they expect to have five of them available in 2016.
Mr. Blain said they are following the development of the internal tank closely, but so far they are having success with external buckets. Thanks and a tip of the hat go out to Tim.
