Conversion of Coulson’s C-130 nearing completion

While it certainly is not ready to drop retardant over a fire today, the conversion of Coulson’s C-130Q into an air tanker is progressing very well.

The company was selected this week by the U.S. Forest Service to receive an exclusive use contract for the 32-year old aircraft that had been sitting in a Wisconsin museum for the last 10 years. Before that it was used by NASA for research, but it began it’s life as a strategic communications link aircraft for the U.S. Navy’s Fleet Ballistic Missile submarine force and as a backup communications link for the U. S. Air Force manned strategic bomber and intercontinental ballistic missile forces.

A C-130Q is similar to a C-130H, but the “Q” model was outfitted with a complex antenna system for communications with submarines and bombers.

In addition to building and installing the retardant tank, the work going on at the San Bernardino airport includes inspections which required that some of the skin be removed from the wings and other surfaces. The inspection is almost done and the aircraft is being put back together.

Britt Coulson told Fire Aviation that the top portion of the retardant tank is finished and the bottom is nearing completion. They expect to conduct flights in June leading toward FAA approval for a restricted category type certificate. They will also need to go through a test for the Interagency AirTanker Board which involves dropping retardant into a grid of cups on the ground to determine consistency and quantity.

In a Coulson company newsletter published on the internet in February, 2012, Jim Messer, Chief Operating Officer, described the process they went through in selecting the aircraft to be used as an air tanker:

…To get to this point we conducted an extensive review of various aircraft capabilities and performance, looking at over 30 aircraft before concluding that the C-130 is the best available.

In the process to acquire an aircraft specific for the airtanker role, Coulson focused on those airframes that were designed specifically for the mission profile of aerial fire fighting. Although many retired high time airlines designed for high altitude point to point flights were available at lower cost they were discounted for the mission required in the fire fighting role.

The C-130Q aircraft was designed to undertake aerial wildland fire operations. Its manoeuvrability, and performance, operating at low levels at low speed with, heavy loads in rugged terrain, immediate power response, and STOL capabilities makes the C-130 a natural fit as an Airtanker.

Thanks go out to Britt and Ryan

Coulson’s C-130 conversion in San Bernardino

The Press-Enterprise has an article about the air tanker conversion that Coulson is working on at the San Bernardino, California airport, converting into an air tanker what the article identifies as a C-130Q. According to the article test flights are scheduled to begin in April. Coulson is hoping to receive a next-generation air tanker contract for the aircraft.

Wildfire Today first wrote about Coulson’s C-130 April 9, 2012.

Santa Maria reduces air tanker landing fees

The Santa Maria Public Airport 55 miles north of Santa Barbara, California has reduced the landing fees charged to air tankers using the airport. An article in the Santa Maria Times says the fees will be reduced from $1 per 1,000 pounds to 50 cents per 1,000 pounds. In addition to this fee, firefighting aircraft have to pay ramp handling fees and fuel flowage fees.

After being downgraded to a call-when-needed air tanker base for three years, the Los Padres National Forest in October, 2011 restored it to full-time status during the fire season.

Contracts for next-generation air tankers

Late in the day last Wednesday the U.S. Forest Service announced contract awards for eight “legacy” air tankers, which included seven P2Vs and one BAe-146. Some people within the agency thought contracts for next-generation air tankers would also be announced last week, but that did not happen. The USFS is probably bending over backwards this time in an attempt to minimize the chances of the awards being protested again. Last summer after the awards were announced but not yet finalized, two companies that were not slated to receive contracts filed protests, which sent the agency back to the drawing board, starting the process over again after making dozens of changes in the solicitation.

It has been 487 days since the USFS began the solicitation process for next-generation air tankers.
