Mammoth Freighters wins FAA approval for 777-200LRMF aircraft

Mammoth Freighters has received certification from the Federal Aviation Administration (FAA) for its 777-200LRMF (Long Range Mammoth Freighter), clearing the aircraft for commercial service and marking a major milestone in the company’s widebody freighter conversion programme.

The FAA approval validates the aircraft’s design, engineering and performance. The 777-200LRMF is designed to offer long-range capability, payload efficiency and operational reliability, positioning it as a versatile option for global cargo networks.

Bill Tarpley, Chief Executive Officer of Mammoth Freighters, said the certification reflects years of engineering work and close collaboration with the FAA. He added that the approval highlights the company’s ability to deliver a high-performance freighter that meets the changing demands of cargo operators worldwide.

Jordan Jaffe, Chief Executive Officer of Jetran, the launch customer for the programme, said the milestone is significant for both companies. He noted that Jetran has had strong confidence in Mammoth’s engineering team and said the aircraft’s quality and technical execution have met expectations. He added that the conversion is expected to be a competitive option in the long-haul freighter market and deliver value to Jetran’s customers, including DHL, Qatar Airways and Ethiopian Airlines.

Drew McKnight, Co-CEO and Managing Partner at Fortress Investment Group, said the certification validates the company’s engineering capabilities and investment strategy. He added that the approval reflects successful collaboration between private industry and the FAA, and strengthens the company’s position to meet long-term global demand for freight aircraft.

The 777-200LRMF programme is based on the Boeing 777 platform and includes Mammoth’s proprietary conversion design. The aircraft features a large main-deck cargo door, a reinforced floor structure and a flexible cargo handling system. It is designed for both long-haul and regional freight operations, supported by its range and fuel efficiency.

With certification completed, Mammoth Freighters is now set to begin aircraft deliveries and entry into service. The company is also progressing with its 777-300ERMF programme and expects FAA certification for that variant later this year.
