Helimax prepares for the 2016 fire season

We stopped by the Helimax Aviation facilities at McClellan Air Field near Sacramento recently and talked with General Manager Josh Beckham and Director of Fire Operations Larry Kelly. Their mechanics were going over their fleet of helicopters preparing them for the upcoming fire season.

HelimaxTwo of their three CH-47D Chinooks are on a Type 1 exclusive use contract. One of them today became the company’s first helicopter to leave the nest this year, beginning work in Sierra Vista, Arizona.

Mr. Beckham told us that they expect to buy “probably two to start with” of the internal 2,800-gallon tanks being built by Jordan Aircraft Services. He said the first one is nearing completion and they hope to begin flight testing in the next couple of months. The water or retardant will be pushed out of the horizontally mounted cylindrical tanks by a 54-inch piston.

Mr. Beckham said Helimax also has six Type 2 helicopters on exclusive use contracts, five 205A1++’s and one 212HP.

On injured reserve is a Super Puma which needs some work — it was hoisted out of the ocean when it became floating debris after the 2011 Tsunami in Japan.

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.

Internal tank being developed for Chinook

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.
