The company has orders to convert 35 777s from passenger to cargo layouts, including nine modified 777-200LRs to be delivered to DHL as part of a recently revealed agreement.
Mammoth is also in advanced negotiations to sell an additional ten modified Boeing widebody aircraft, according to the Orlando-based company's VP of marketing and sales, Brian McCarthy. He notes that the first modification, a 777-200LR for Canadian carrier Cargojet, is on schedule for completion by the close of 2022.
Originally, Mammoth aimed to have its 777-200LRMF modification approved by the Federal Aviation Administration (FAA) with a supplemental type certificate (STC) in 2023. However, McCarthy expects that with the year-end completion, the FAA will likely issue the STC in 2023, possibly by April. He also predicts that Mammoth will receive an STC for its 777-300ERMF conversion approximately six months later.
Mammoth's affiliate, Aspire MRO, is performing the conversion work at a former American Airlines 777 maintenance site at Fort Worth Alliance Airport in Texas. The company is in the process of setting up three modification lines at the location, with plans to eventually expand to five lines. Additionally, Mammoth has enlisted UK MRO firm STS Aviation Services to establish another modification facility in Manchester.
Mammoth has acquired ten 777-200LRs from Delta for modification, four of which are slated for delivery to Canadian freight carrier Cargojet. The remaining six have been sold to U.S. aviation services and aircraft leasing firm Jetran.
DHL announced on April 20 that it has ordered nine Mammoth-converted 777-200LRs from Jetran, with deliveries set to take place between 2024 and 2027.
Mammoth's 777-200LRMF will offer a cargo volume of 650 cubic meters (22,960 cubic feet) and a maximum gross payload of 105,687 kg (233,000 lb), while its 777-300ERMF converted freighter will provide 814 cubic meters of cargo volume and the capacity to transport up to 99,790 kg of payload. Other companies offering 777 cargo conversions include Israel Aerospace Industries and Kansas Modification Center.
