Overview

• The CV-22B Osprey fleet was grounded after a crash in Japan last November killed eight service members.
• Four fatal crashes in the past two years have led to 20 deaths and prompted extensive reviews of the aircraft.
• Investigations revealed that mechanical failures, including a critical pinion gear crack, were key factors in the crashes.
• About 60% of the Osprey fleet has returned to full flying status, with the remainder expected by early 2025.
• New deployment will include flight restrictions, requiring aircraft to stay within 30 minutes of a suitable landing site.
