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.
Billings Flying Service just became the first non-military owner of CH-47D Chinook helicopters. Gary Blain, a co-owner of the company, told Fire Aviation that the process was much like purchasing a used government-owned vehicle. He submitted a $6.5 million bid for two of them and it was accepted.
Columbia Helicopters has BV-234 Chinooks, but this is the first time the higher performance CH-47D models have migrated into the civilian world.
On Wednesday and Thursday Mr. Blain and another pilot flew the two Chinooks 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 said they spent $32,000 for fuel during their two-day trip, with an overnight stopover in Norfolk, Nebraska.
In about four months they expect to have one of them outfitted for wildland firefighting, with the other coming on line next year. He said with an external bucket the ships could deliver 2,500 gallons of water. They have been consulting with the manufacturer, Boeing, and are considering installing an internal water tank with a snorkel and water pump for refilling the tank. The Chinook has an unusually high capacity for electrical accessories, so they are looking at either an electrical or a hydraulic pump. The water would exit the tank either from the rear ramp or through a hole cut in the belly. We asked if the tank would be similar to the RADS tank pioneered by Aero Union, and Mr. Blain said that if they choose the internal tank option they would probably work with Boeing to engineer something new.
When operated by the military the Chinooks have a three-person crew, two pilots and an engineer-type who monitors gauges and interfaces with passengers. Billings Flying Service will not haul passengers, so they will reconfigure the cockpit making it possible for two pilots to handle everything. They will also install a bubble window to improve the visibility when flying external loads.
The company expects to hire at least 15 new employees to complete the work on the two helicopters. They will also construct a hanger for the ships, either at their headquarters or at the Billings airport.
Billings Flying Service is a second generation helicopter company and currently has one Bell 212 on an exclusive use firefighting contract and three Sikorsky S-61s and two Bell UH-1Hs on call when needed contracts. In addition to aerial firefighting, they are experienced in aerial construction, power transmission line construction, equipment transportation, geo-seismic exploration and passenger air charter.
Pilots and firefighters at Fort Carson near Colorado Springs conducted training earlier this month with the goal of becoming qualified to use CH-47 helicopters to drop water on wildfires. Below is an article provided by the Fort Carson Public Affairs Office.
Story by Sgt. Jonathan Thibault
FORT CARSON, Colo. – Splish splash — Colorado Springs wildfires could be getting a bath. Pilots of the 4th Combat Aviation Brigade, 4th Infantry Division, were conducting Bambi Bucket training on Fort Carson, April 4.
A Bambi Bucket is a specialized bucket that carries about 2,000 gallons of water, suspended on a cable carried by a helicopter for aerial firefighting. When the helicopter is in position, the crew opens the release valve to battle the fire below.
Officials with 4th Inf. Div. and the Fort Carson Fire Department are working together to receive approval of the Bambi Bucket mission, so the 4th CAB can assist with firefighting efforts in the Colorado Springs area.
“These missions would give 4th CAB the capability to help other agencies fight wildfires,” said Chief Warrant Officer 4 James Dowdy, battalion standardization officer and senior CH-47 Chinook pilot, 2nd General Support Aviation Battalion, 4th Aviation Regiment, 4th CAB, 4th Inf. Div. “4th CAB could help reduce or prevent the loss of lives and property damage due to wildfires.”
“We hope to get a positive interaction from the surrounding communities and support them the best way we can,” said Capt. Sean Pearl, commander, Company B, 2nd GSAB, 4th Avn. Reg. “We have three crews training for this mission and will train future Chinook crews as they arrive to 4th CAB.”
The CAB soldiers could be a strong reactive force in preventing and fighting wildfires in Colorado.
“Due to our training, we would be able to react quicker than most agencies and our helicopters can get into areas that most aircraft cannot,” said Dowdy. “The ability to respond quickly to these emergencies makes 4th CAB versatile and allows our Chinooks to perform at various locations worldwide.”
“We are currently discussing protocols with Colorado Springs firefighting agencies to better facilitate our mission to best fit their needs,” said Pearl.
The aviators hope to get the Bambi Bucket missions to get more flight training and prevent the spread of future wildfires. “It is a fairly simple mission because our CH-47 Chinooks are designed to carry external loads, such as the Bambi Bucket,” said Dowdy. “This mission would provide 4th CAB aviators a real-world mission that cannot be done through simulation and also make a positive impact on the surrounding civilian population.”
Fort Carson and the 4th Inf. Div. can only deploy military resources to support firefighting efforts when requested by the National Interagency Fire Center and approved by the Secretary of Defense. At that point, Fort Carson’s support would be coordinated through U.S. Northern Command, located at Peterson Air Force Base. NIFC can only request Department of Defense support after all other local, state and federal resources have been exhausted.
