Airworthiness Directives; McCauley Propeller Systems

Summary

The FAA is adopting a new airworthiness directive (AD) for certain model McCauley Propeller Systems (McCauley) governors installed on airplanes. This AD was prompted by reports of an unapproved variant McCauley idler gear bearing, part number (P/N) A-20028, that could be installed in the affected governors. This AD requires replacing the governor with a governor that is eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
