Mammoth Freighters has secured certification from the US Federal Aviation Administration for its 777-200LRMF, or Long Range Mammoth Freighter, a key milestone for the Texas-based company after a lengthy wait for regulatory approval.
The certification gives Mammoth the green light to move ahead with aircraft deliveries and entry into commercial service, confirming that the converted freighter meets the FAA’s standards for design, engineering and operational performance.
With the approval now in place, the 777-200LRMF enters the market as a platform aimed at operators needing a combination of long-haul range, payload efficiency and dependable performance across global cargo networks. Mammoth says the aircraft is designed to serve both long-distance and regional freight missions with equal flexibility.
Bill Tarpley, chief executive of Mammoth Freighters, said the approval reflects years of engineering work, close coordination with the FAA and the commitment of the company’s internal teams and partners. He added that the certification confirms the strength of Mammoth’s technical strategy and its ability to deliver a high-performance freighter suited to the changing needs of cargo operators worldwide.
The milestone is also significant for launch customer Jetran. Jordan Jaffe, chief executive of Jetran, said the certification marks an important step for both companies and underlines the confidence Jetran has had in Mammoth’s engineering team since the start of the programme.
He said the quality of the aircraft and the execution of the conversion had met expectations, adding that the 777-200LRMF is expected to be a strong and competitive option in the long-haul freighter market. He also said the aircraft should offer solid value for Jetran customers, including DHL, Qatar Airways and Ethiopian Airlines.
Drew McKnight, co-chief executive and managing partner at Fortress Investment Group, said the FAA approval validates the world-class engineering behind Mammoth and the disciplined investment that helped build the company over the last five years. He described the certification as an example of successful collaboration between private industry and the FAA, and said Mammoth’s fully integrated US-based production platform is well positioned to serve long-term global demand for freighter aircraft.
Among the main features of the 777-200LRMF are what Mammoth describes as the largest main-deck cargo door in its class, a reinforced floor and a flexible advanced cargo handling system. Together with the aircraft’s range and fuel efficiency, those features are intended to support a broad mix of freight operations.
Mammoth is also continuing work on its 777-300ERMF programme and expects that variant to receive FAA certification later this year.
