Photos of Coulson’s 737-300 air tanker

The company expects to have the conversion complete by the end of this year.

On May 21 we told you about Coulson Aviation branching out into a new line of air tankers to add to their three C-130s and a fourth C-130 that is being converted now. The company has purchased six 737-300’s from Southwest Airlines and intends to convert at least some of them into air tankers.

The first conversion has started, with a freshly painted 737 rolling out of the paint shop in Spokane today.

The next step is to add a gravity-based tank which will have the same technology used on their C-130’s.

The air tanker is being designed as a multi-use aircraft with the ability to haul passengers. Britt Coulson said, “With a full retardant load and 4.5 hours of fuel we are so far under max gross weight we are going to leave the full interior and galleys in even when just in airtanker mode.”

Coulson to convert 737’s into air tankers

Coulson Aviation is adding not only additional air tankers to their fleet, but is branching out into a different model of aircraft. The company has purchased six 737-300’s and intends to convert them into 4,000-gallon “Fireliner” air tankers. Britt Coulson said they saw an opportunity when Southwest Airlines made a decision to replace their 737-300’s with the new 737-Max. Since the FAA only allows Southwest pilots to fly two of the 737’s with the same rating, the airline opted to sell the 737-300’s even though they have a relatively low number of hours in the sky.

The first conversion has started, with a freshly painted 737 scheduled to roll out of the paint shop in Spokane on May 22, 2017. The next step is to add the gravity-based tanks which will have the same technology used on their C-130’s.

The air tanker is being designed as a multi-use aircraft with the ability to haul passengers. Mr. Coulson said, “With a full retardant load and 4.5 hours of fuel we are so far under max gross weight we are going to leave the full interior and galleys in even when just in airtanker mode.”

The company likes the three C-130’s that they have already converted to air tankers, but finding additional C-130’s for the civilian market is very difficult.

A 737 will be able to use some air tanker bases that larger aircraft, like the C-130, can’t, with a wingspan that is about 38 feet shorter.

Mr. Coulson said they expect to begin installing the retardant system in June with a completion date of December of this year. When that is complete they will start on another. The first conversion will be done by Coulson Aircrane Canada.
