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 a detached flap motor wire bundle mount, leading to severe chafing and exposed wires requiring inspection and replacement.
- The FAA reminded Cessna 208B operators and technicians about the mandatory 100-hour elevator torque tube inspection, specifically emphasizing critical rivets.
- Slick Magneto models 6351 and 4371 reported manufacturing defects like improperly spaced distributor gears and operational failures such as unseated rotor gears causing internal damage.
- A Bendix Magneto S6RN-1208 was found with a broken contactor rivet, speculated to be due to insufficient strength, during ignition system troubleshooting.
