HURLBURT FIELD, Fla. —  

Today, Air Force Special Operations Command released an Accident Investigation Board report on a CV-22B Osprey mishap that occurred Nov. 20, 2024, near Melrose Air Force Range, N.M.

The mishap resulted in no injuries or fatalities nor damage to civilian property. The estimated cost of damage to government property was valued at approximately $2.8 million.

The AIB President found by a preponderance of the evidence, the cause for the mishap is attributed to a catastrophic failure of the left hand proprotor gearbox lower input idler helical gear (-105) due to a materiel inclusion in the gear’s rim-to-web radius interface.
