The failure of the torque sensor idler gear duplex bearing during agricultural aerial application, resulting in a total power loss and a forced landing. Factors include tall wheat and soft terrain.
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.
