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:

• An Aviat A-1 experienced total loss of elevator control on final approach due to an uncoupled pushrod, caused by loose hardware and improper nut installation.
• A Beech B60 was found to have corroded flight control cables and seized pulleys during an annual inspection, resulting from water collection in the aircraft's belly.
• Engine malfunctions included a Lycoming O-320-D36 with idle issues caused by a leaking carburetor float, and a Lycoming O-360A4M experiencing a cylinder head separation mid-flight.
