Extra-large Air Tanker news

NASA studies the DC-10 and 747 air tankers

(From the Victorville Daily Press)

The firefighting DC-10 Supertanker, based at Southern California Logistics Airport, is being studied by NASA in what could pave the way for the plane’s first federal contracts.

The jet’s owner, 10 Tanker Air Carrier, has been trying for some time to get a contract with the U.S. Forest Service that would allow the agency to fight fires on federal land, managing partner Rick Hatton said. The Forest Service approached NASA for help in determining the best use for the plane.

“They came to see us in Victorville with six or seven people last month,” Hatton said. “We briefed them on the plane and how effective it’s been for the state of California and how effective it could be for the federal agencies.”

NASA’s Dryden Flight Research Center at Edwards Air Force Base, about 30 miles northwest of Victorville, will be studying the supertanker to determine its “safe flight envelope.” The team will then recommend operational use regimes, policies and procedures for the aircraft.

The NASA team has spent the past few days in Miami, Hatton said, using an advanced DC-10 flight simulator to perform some preliminary tests.

“We hope to get the NASA team on the DC-10 in a fire environment,” Hatton said, so the company can show NASA what the plane can do.

If not, he said they’ll do mock drops with water in a remote place over the desert, hopefully within the next few weeks.

“The entire team is very excited about helping the Forest Service with this effort,” said Mark Dickerson, project manager for Dryden. “It is a bit different from our typical research projects, but we all enjoy being able to help find new tools to fight wildfires.”

NASA is also studying a Boeing 747 owned by Evergreen International Aviation.

Hatton said his company has hope that the final report will be done in the next few months.

Contract extended for DC-10 Air Tanker

Though the DC-10’s Supertanker’s contract with Cal Fire would have ended Oct. 15, 10 Tanker Air Carrier managing partner Rick Hatton said it’s been extended through the end of October. Santa Ana winds picking up and the dangerously dry conditions are rattling some nerves.

“It’s been a weird season,” Hatton said. “It was very busy early in the summer. We flew more mission in June and July than all of ‘07. But it’s been quiet for August and September. Now there’s this huge fear that all hell could break lose.”

The tanker was used to fight the Porter Ranch fire that engulfed parts of Los Angeles two weeks ago, but the plane has been grounded for the past few days. Last year, during its first year under contract with Cal Fire, the tanker flew 106 missions in fighting more than a dozen large wildfires.

Hatton said a recently completed second DC-10 is ready to come on line soon, with plans to get contracts in place for next year’s fire season.

747 Supertanker update

Wildfire Today has learned that Evergreen International Aviation is still hoping to obtain a contract with Cal Fire for their 747 air tanker, or “Super Tanker”, as they call it. The ship has been in Marana, Arizona for the last 3-4 weeks undergoing testing which involved static tests on the ground as well as drop tests over the Black Mountains.

They have made some modifications on the aircraft and expect to get a Supplemental Type Certificate from the FAA as early as today. Evergreen also hopes to obtain the approval of the Interagency Air Tanker Board, a group of federal aviation specialists that certifies air tankers.

Evergreen has been optimistic about this approval process, in spite of the fact that their negotiations with the U.S. Forest Service fell through in September. In a best-case scenario, the 747 could be flying for Cal Fire in a few weeks.

Extra-Large air tankers
  1. Martin Mars: 7,200 gallons (water, retardant, gel, or wildland foam); one is under contract with the U.S. Forest Service
  2. DC-10: 12,000 gallons (water or retardant); one is under contract with Cal Fire
  3. 747: 20,000 gallons (water or retardant); one may be under a contract later with Cal Fire

USFS cancels potential contract for 747 air tanker

Wildfire Today has learned that the U.S. Forest Service has cancelled their soliciation which could have led to a contract for a 747 air tanker. However, CalFire is pursuing a call when needed contract along those lines and they may have something in place by October.

If this happens as expected it will be another feather in CalFire’s cap, placing another tool in their aviation toolbox alongside the DC-10 and thier fleet of S-2’s. Earlier this year the U.S. Forest Service signed a call when needed contract for the huge Martin Mars, which has been used quiet a bit in northern California this summer in the Seige of ’08.

747 air tanker soon under contract?

Evergreen submitted their contract proposal to the U.S. Forest Service today and James Baynes, the Supertanker Sales Manager, told us that they expect a contract to be awarded “shortly”. The 747 “Supertanker” can carry 20,000 gallons of retardant, about seven times more than a typical large air tanker. Like other air tankers, it will not put out any fires by itself, but it’s another tool in the firefighter’s tool box, at a time when we need more.

Update on Evergreen's 747 air tanker

I made some inquiries and found out the status of Evergreen’s 747 air tanker. They are still in contract negotiations with the U. S. Forest Service and will soon submit to them a proposal. They are confident that they will have a contract soon thereafter. The aircraft will carry 20,000 gallons and can cruise at mach .85, or 600 mph.

Here is a 22-second video of the 747 dropping water.

DC-10 and 747 air tankers

The DC-10, designated as air tanker 910 and operated by 10 Tanker Air Carrier out of Victorville, California, is on contract for a second year to CalFire. It was used this weekend in northern California on some of the fires in Tehama County. Instead of reloading at Victorville as usual, it filled it’s 12,000 gallon tanks at CalFire’s air tanker base at McClellan. The company is also building a second DC-10 air tanker.

Evergreen International Aviation of Oregon expects to have their 747 air tanker under contract with the U.S. Forest Service within the next 2-5 weeks. It will carry 20,000 gallons and can cruise at mach .85, or 600 mph.

Here is a 19-second video of the DC-10 making a drop on the Humbolt fire near Chico, CA a week or two ago. Turn up the sound so you can hear the audio. The sound of those jet engines from an air tanker will be hard to get used to. When I first started fighting fire, some of the air tankers used the huge radial engines that have a sound you will hear no other place. Another big step was putting turbine engines in the smoke jumper’s DC-3; hard to get used to. Now jets dropping on fires? What’s next? Saturn 5 rockets carrying 1,000,000 gallons of retardant?
