The Federal Aviation Administration has granted Supplemental Type Certification to Mammoth Freighters for its 777-200LRMF Long Range Mammoth Freighter, allowing the converted widebody aircraft to enter commercial service.
Mammoth Freighters announced the approval on April 8, 2026, following years of engineering and collaboration with the FAA. The certification covers the aircrafts design, performance, and engineering. Bill Tarpley, CEO of Mammoth Freighters, stated that the approval validates the companys technical approach for high-performance freighters.
Jetran, the first customer, identified Qatar Airways Cargo as the launch operator for five aircraft. The first 777-200LRMF is undergoing painting in Qatar Airways livery, though delivery timing remains unconfirmed. Jetran also named DHL and Ethiopian Airlines as future operators. Jordan Jaffe, Jetran CEO, noted that the aircraft meets high standards in quality and execution.
The 777-200LRMF includes the largest main-deck cargo door in its class, a reinforced floor, and an advanced Collins Aerospace cargo loading system optimized for passenger-to-freighter conversions. With certification secured, Mammoth plans to start deliveries while advancing FAA approval for the 777-300ERMF later this year.
