Mammoth Freighters LLC has signed a General Terms Agreement with STS Aviation Services (STS) to perform passenger-to-freighter conversions for the Mammoth 777 program. All work will be accomplished at STS’s facility in Manchester, UK, and the multi-year agreement covers both the 777-200LR and 777-300ER aircraft. “Ensuring that we have the right modification capacity in place around the world to meet the robust demand for the Mammoth 777 freighter program is vital to our success. STS has the experience, knowledge, capability, and, most importantly, the high-quality reputation that we look for in an MRO partner. We are excited to have STS on our team and look forward to a productive, long-term relationship,” said Mammoth’s Senior Vice President of Operations, David Steinmetz. The STS facility will also provide Mammoth with AOG, product support, and spares provisioning throughout Europe. STS acquired the Manchester facility earlier this year as part of its expansion efforts, and this constitutes its third facility in the UK. Mammoth will begin inducting 777 aircraft for modification at the facility in mid-2024.
