Steinhagen became senior vice president of program management at Mammoth in January 2023. He previously served in various leadership roles with Boeing for more than twenty-two years, including director and senior business development manager.
In August, Mammoth redelivered its first 777-200LRMF converted at the STS Aviation Services facility in Manchester, England (MAN), to Horseshoe Bay, Texas-based aircraft trader Jetran.
The conversion company is completing flight tests to certify the 777-200LRMF to perform automated landings at the designed maximum landing weight of 572,000 pounds.
Mammoth received FAA approval for its 777-200LRMF on April 7 and is working on completing and certifying its 777-300ERMF conversion with the agency.
