One of the two DC-10 Very Large Air Tankers that deployed to Chile is en route back to the United States now that the wildfire activity has slowed and the contract has ended. It is scheduled to land at San Antonio at 6:59 p.m. CST today, March 2, after a stop in Manta, Ecuador. On FlightAware it is operating as TNKR910, N612AX. 10 Tanker Air Carrier’s headquarters is at Albuquerque, New Mexico.
The second DC-10, Tanker 914, arrived in Chile on February 11. Its contract ends next week and then it will be heading back north.
The two DC-10s have been working out of three airports stretched across 572 miles of the long, narrow country — Santiago, Concepción, and Puerto Montt.
As of March 1, the two aircraft have completed 133 missions dropping a total of 1.2 million gallons, an average of 9,022 gallons per mission, said John Gould, President of 10 Tanker Air Carrier. For the first week or two they were dropping plain water since there is no fire retardant in Chile, but later fire officials requested they use BlazeTamer, a concentrated water enhancer that can be injected into the tank using the existing equipment on the air tankers. The product was used on 33% of the missions.
A Chilean Navy P-295 (as seen below) is serving as a lead plane for the DC-10. Also known as a Casa, a P-295 served as a lead plane ahead of the 747 when it worked in Chile in 2017. He was not allowed to fly it, but former smokejumper and lead plane pilot Jamie Tackman went along as a passenger in the Casa in 2017, kneeling between the pilots, giving them instructions on where and when to drop. This year there are no U.S. lead plane pilots in the P-295.
A DC-10 very large air tanker was damaged when a tire failed upon landing at the Carriel Sur airport in Concepción, Chile Friday November 8. The tread separated on a main landing gear tire and damaged an inboard flap. John E. Gould, President of 10 Tanker Air Carrier, said the crew immediately began repairing the flap and that work will be completed Monday afternoon.
When tires on a race car or aircraft disintegrate at high speed as shown in the photo, chunks of rubber flying off the tire can damage sheet metal and other components.
Very roughly translated news reports indicate that the aircraft completed either four sorties or four drops on its first day of operations in Chile before the tire failed. T-910 departed from San Bernardino, California on February 6, arrived in Chile the following day, and went to work dropping on wildfires February 8.
Mr. Gould said a second DC-10, Tanker 914 has been ordered and is en route, expected to arrive in Santiago, Chile Monday afternoon. It is not necessarily to replace T-910; CONAF, the contracting organization, wanted a total of two very large air tankers under contract.
The video below shows both a Russian IL-76 and the DC-10 making drops. It is possible that a water enhancing chemical has been added to the water to increase its effectiveness in suppressing the wildfires. The DC-10 can carry up to 9,400 gallons. The IL-76 footage may be from 2017.
The conversion of the fourth DC-10 into a Very Large Air Tanker is nearing completion. Rick Hatton, the President and CEO of 10 Tanker Air Carrier, said he expects Tanker 914 to be finished with the modification process in June, including the incorporation of their Next Gen tank controller.
Tanker 914 will join the other three DC-10’s that can each hold up to 11,600 gallons of fire retardant.
