Accident · substantial damage
Feb 16, 2022 · Jolon, CA
The separation of a propeller blade during expansion flight testing that resulted in cascading effects to include the separation of multiple propulsion motor/propeller assemblies and the loss of remote pilot control of the aircraft. Contributing to the accident was the tilt rotor actuator linkage for propulsion station 3 that allowed some propeller blades to be at a steeper angle than commanded.
These match the airframe or engine model. Whether each one applies, and whether it's been complied with, depends on serial numbers, equipment and logbook entries. Applicability must be confirmed by a mechanic against the aircraft's records.
No ADs published since 1998 matched this airframe or engine model.
AI-extracted — verify against original. Matched from each AD's applicability section; ADs replaced by a later AD are left out.
