Bent, Corroded, Cracked

A pilot reported total loss of elevator control on final approach. Investigation revealed the rear control stick was no longer connected to the elevator push rod. The aft belly pan was removed and a loose bolt and washer were found. The nut was not found. The other rod ends were inspected for safety; the self-locking nut and bolt for the aft interconnect push rod was very loose. The existing hardware was not reinstalled because it was found loose during the inspection. New hardware was installed for each noted discrepancy. The owner was advised to have a factory service center inspect the aircraft, and make repairs according to the maintenance manual and parts book.

Key Takeaways:

• Aircraft experienced critical flight control failures, including an uncoupled elevator pushrod on an Aviat A-1 due to loose hardware and corroded cables and seized pulleys on a Beech B60 caused by water submersion.
• Engine malfunctions were reported, such as a Lycoming O-320-D36 having RPM issues due to a leaking carburetor float, and a Lycoming O-360A4M experiencing a cylinder head separation after 206 hours of service.
