Mammoth Freighters has cut the first door on its inaugural 777-300ERMF freighter conversion.
The large maindeck cargo door is designed to be 16 inches wider than the 777F, to allow for a variety of cargo shipments.
"The freighter will be converted and certified under an amended STC, with both the 200LR and 300ER included under one project number," said Mammoth in a LinkedIn post on Tuesday 13.
Leasing firm AviaAM Leasing was revealed as the launch customer for Mammoth's 777-300ER (ERMF) freighter conversion programme in 2022, after signing up for six of the aircraft.
Mammoth then inducted the first of the six aircraft for conversion in October last year.
Brian McCarthy, vice president of marketing and sales at Mammoth told Air Cargo News: "The FAA is administrating the Mammoth Freighter conversion under one project number with the 200LR considered the Master STC. After issuance of the 777-200LR STC, it will be amended to add the Mammoth 777-300ER variant.
"Based on our current projections and completion of the 200LR at year end we hope to have the 300ER amendment within 6 months of the 200LR STC issuance."
He said that Mammoth expects the first Avia 300ER to enter service in summer 2025. Two more 300ERs are due to enter into the production lines in 2025 and a further two in 2026. All six aircraft are due to be delivered by mid-2027.
AviaAM Leasing chief executive Tadas Goberis, and his team attended an event to mark the door cutting, said Mammoth in its post yesterday.
The door-cutting process for the 777-300ERMF was carried out at Aspire MRO’s facility at Fort Worth Alliance Airport in Texas, where the conversion process for the aircraft began last year.
The 777-300ERMF will be able to carry 99 tons of cargo on transatlantic routes and is earmarked for EU-US or China-EU operations.
Mammoth Freighters announced its plans for Boeing 777-200LR and 777-300ER passenger-to-freighter conversion programmes in September 2021.
Cargojet became the launch customer for Mammoth’s B777-200LR freighter conversion programme in November of that year.
Aspire MRO launched widebody MRO and Passenger-to-Freighter (P2F) conversion services in August 2022.
There are currently three 777-300ER conversion programmes in place with Israel Aerospace Industries (IAI), Kansas Modification Center (KMC) and Mammoth, plus one 777-200LR programme in development with Mammoth.
“IAI and Mammoth are further ahead and more likely to launch sooner,” commented IBA analyst Jonathan McDonald in a July webinar.
