AviaAM leasing has signed on as launch customer for Mammoth Freighters’ 777-300ERMF freighter conversion, inking a deal for six of the widebody twinjets, the companies said Oct. 13.
Work on the first freighter, which will support the FAA supplemental type certification process, is expected to begin in “early 2023,” Mammoth said in a statement announcing the deal. All six conversions are slated to be done by mid-2026, the company told Aviation Week.
Conversion work will be done at Aspire MRO, which recently unveiled plans to enter the widebody airframe maintenance and freighter conversion business at Alliance Airport in Fort Worth, Texas.
“We are excited that AviaAM has selected Mammoth and will be the launch customer for the 777-300ERMF,” said Co-CEO Bill Tarpley. “As AviaAM expands its strategic focus in the cargo sector, the superior widebody operating economics of the Mammoth 777-300ERMF will perfectly compliment their growing fleet of next generation freighters.”
The six aircraft are coming from AviaAM’s portfolio, which has been adding freighters. The Vilnius, Lithuania-based lessor recently delivered its third 737-800 Boeing Converted Freighter and has plans to build its fleet of freighters to 25 in the next few years. It also has one 747-400F in its portfolio.
Mammoth’s preliminary targets for its 777-300ERMF include a 220,000 lb. max gross payload and a 775,000 lb. maximum takeoff weight. Its total cargo volume of 28,739 ft.3 its 14% more than a 747-400F and 43% more than an MD-11F, the company said.
Founded in December 2020, Mammoth is eyeing the growing fleet of older 777s and the strong air cargo segment. It has firm orders for 29 conversions and 12 more “in advanced stages of commitment.” The company also offers 777-200LR conversions and said recently it is on track to obtain certification in late 2023. Cargojet is the program’s launch customer.
