Since its inception, the V-22 Osprey tiltrotor aircraft has faced ongoing scrutiny and mechanical challenges. Despite improvements, recent events have highlighted persistent issues with its gearbox system.
The entire fleet of V-22s was grounded following an emergency landing by a USAF Special Operations Command (AFSOC) CV-22. AFSOC Commander Lt. General Jim Slife noted that while no catastrophic mishaps were directly linked to the "hard clutch engagement," it remains a serious concern. He credited impressive feats of airmanship for preventing disasters during these events.
The Osprey's propulsion system, which allows vertical takeoff and horizontal flight, relies on a complex drive system transferring power from engines to proprotors. This complexity can strain components like the gearbox, prompting renewed restrictions after excessive metal shavings were found in the gearbox post-crash in Japan in November 2023.
