AviaAM, Mammoth Near Completion Of First 777-300ER P2F Conversion

AviaAM Leasing is nearing completion of its first Boeing 777-300ER passenger-to-freighter (P2F) conversion with U.S.-based partner Mammoth Freighters LLC.

AviaAM Leasing is part of Avia Solutions Group while Mammoth Freighters LLC specializes in 777 P2F conversions. The project is expected to be completed by the end of this year.

The process of seeking to obtain a supplemental type certificate (STC) for the aircraft is already underway with the FAA, AviaAM deputy CEO Rytis Kriunas told Aviation Week.

“The aircraft is currently undergoing prototype conversion, and STC approval is essential to finalize the process. As this is the first aircraft of its type being converted, it is difficult to predict the exact timeline for completion and certification,” Kriunas said. “Upon completion of the prototype aircraft and receipt of the STC, the aircraft will be dry leased to our sister company BBN Turkey Airlines for their ACMI operations. Following that, the second B777-300ER will be inducted for the conversion.”

“This type of conversion of a popular passenger aircraft is a historic achievement for AviaAM Leasing,” Avia Solutions Group Jonas Janukėnas said. “Boeing foresees air cargo operators will need more than 2,600 freighters over the next two decades to keep up with increasing global freight traffic. P2F conversions are one way to meet this growing demand.”

“Once converted, the Boeing 777-300ERMF will be one of the most fuel-efficient long-range freighters available,” Mammoth Freighters VP of sales and marketing Brian McCarthy said. “Its impressive payload capacity and range make it an attractive option for cargo operators worldwide.”

A 777-300ER can carry nearly 400 passengers in a standard two-class layout. Once converted, the aircraft can transport up to 98 tons over 5,000 nm with a volume of 819 m3 of cargo on long-haul routes, including transatlantic operations, AviaAM said.

“This project will help us strengthen our position in the cargo aircraft leasing sector, as these converted aircraft will enable logistics companies to expand their capacity,” AviaAM Leasing Tadas Goberis said.

The project is not the only 777 passenger-to-freighter program underway, with conversion companies IAI and Kansas Modification Center also working on their own versions.

Kriunas said AviaAM has secured a total of six conversion slots for Mammoth Freighters’ 777-300ER program. The plan, he added, is to eventually convert up to two aircraft per year, which will then be either dry leased or sold.
