Mooney M20A — Airworthiness Directives

This Airworthiness Concern Sheet (ACS) issued by the FAA addresses a significant safety issue concerning the Mooney M20 series aircraft, specifically the M20C, M20D, M20E, M20F, and M20G models. The document highlights reports of fatigue cracks in the control wheel shaft and attachment hub, which may lead to control wheel separation. Such a failure poses a risk of momentary loss of control, particularly during critical phases of flight like takeoff and landing. The FAA is seeking input from aircraft operators regarding inspection procedures and any observed issues. The document serves as a preliminary communication to gather information before potentially issuing an Airworthiness Directive (AD) or other safety bulletins.

• Fatigue cracks in control wheel shaft may lead to separation.
• Existing AD requires inspection of control shaft every 500 hours TIS, or 1000 hours if strengthened.
• Operators should visually inspect control wheels for cracks.
• Immediate reporting to the FAA is required if cracks are found.
• Responses to the FAA are requested within 30 days.
