Rivets And More
During a scheduled inspection, the wire bundle mount (p/n S2606-2) holding the flap motor wire harness was found detached from the rib in the right wing, allowing the wire bundle to chafe into the inspection panel support on the wing. The wire bundle had two wires which were chafed completely through the insulation, allowing contact with the inspection panel support. Inspecting these mounts and replacing them as needed is recommended.
Key Takeaways:
- A Cessna 172R experienced chafing flap motor wire bundles due to a detached mount, exposing wires to the inspection panel support.
- Cessna 208B operators are reminded to strictly follow 100-hour elevator torque tube inspection requirements, with a focus on specific rivets.
- Multiple magneto failures were reported across different models (Slick 6351, Slick 4371, Bendix S6RN-1208), including improperly spaced distributor gears, unseated rotor gears, and broken contactor rivets.
