Superseding AD Proposed for Lycoming Oil Inspections and Connecting Rod Bushings
The FAA has proposed to supersede AD 2024-21-02 (current AD), which applies to Lycoming engines that have certain connecting rod assemblies installed. The current AD requires repetitive oil inspections for bronze metal particulates and, if found, additional inspections of the connecting rod bushings for damage, proper fit, movement, and wear, and replacement if necessary.
