Mammoth Freighters said it has completed the main cargo door installation for its fifth 777ERMF passenger-to-freighter conversion.
The Fort Worth, Texas-based freighter conversion company announced its latest milestone, carried out with partner Aspire MRO, with a picture post on LinkedIn.
Brian McCarthy, vice president of marketing & sales for Mammoth, confirmed to Air Cargo News that the aircraft is a 777-200LRMF, which will be delivered to launch customer Qatar Cargo when completed.
"Mammoth Freighters and Aspire MRO complete fifth 777 main cargo door installation, with seven total aircraft in production," said Mammoth in the LinkedIn post on 18 August.
Mammoth Freighters plans to complete test flights for its 777-200LRMF converted freighter by early October as it progresses towards Supplemental Type Certification (STC) for the aircraft.
The company announced it had completed the initial test flight of the 777-200LRMF prototype in May.
Qatar Airways Cargo is the launch customer for the 777-200LRMF after earlier this year signing an agreement for five of the aircraft with Texas-based lessor, Jetran.
The first main cargo door installation on Mammoth's 777-300ERMF took place in February. Mammoth is expected to complete flight testing for the 777-300ERMF by the end of the year.
Currently, Mammoth has seven 777-200/-300 aircraft undergoing conversion: five at Aspire MRO in Fort Worth, Texas, and two at STS Aviation Services in Manchester, UK.
There are currently three 777-300ER conversion programmes in place with IAI, KMC and Mammoth, in addition to the 777-200LR programme in development with Mammoth.
