Mammoth Freighters aims to achieve certification of 777-200LRs by 2024

Mammoth Freighters expects to complete its first 777-200LR modification by year-end and to achieve an initial regulatory certification by April 2024. The company said it now holds orders to modify 35 777s from passenger to cargo configurations, including nine modified 777-200LRs due for delivery to DHL. Mammoth is also in “advanced stages” of negotiations to sell another 10 of the modified Boeing widebody jets, the Orlando-based company’s vice-president of marketing and sales Brian McCarthy said in reports. He added Mammoth is on track to complete its first modification – that of a 777-200LR due to Canadian hauler Cargojet – by the end of 2022. Orlando-based Mammoth previously aimed to have its “777-200LRMF” modification approved by the Federal Aviation Administration with a supplemental type certificate (STC) in 2023. But the modification’s expected end-year completion likely means the FAA will grant the STC in 2024 – probably by April, said McCarthy. Mammoth expects to receive an STC for its 777-300ERMF conversion about six months after that, he added. Mammoth’s corporate affiliate Aspire MRO is performing the conversion work in a former American Airlines 777 maintenance site at Fort Worth Alliance airport in Texas. Both Mammoth and Aspire are backed by Fortress Investment Group. Mammoth is initially setting up three modification lines at the site, and already working on conversions of two 777-200LRs (former Delta Air Lines aircraft due to Cargojet) and one 777-300ER (an aircraft owned by AviaAM Leasing).
