MOONEY M20C Model Guide
MOONEY M20C · Model Guide
Overview
MOONEY M20C is a single-engine piston Mooney in the M20 family. Family variants carry up to 4 passengers. The supplied documents give no M20C-specific specs or performance figures, so this guide covers the FAA control wheel concern, parts support and a speedbrake STC.
- The FAA has an open concern about fatigue cracks in the M20C control wheel shaft and attachment hub.
- An existing AD requires control shaft inspection every 500 hours TIS, or every 1000 hours if strengthened per SB M20-205B.
- Parts come only through authorized Mooney facilities. The parts catalog lists both electric and manual gear retraction systems.
- A Precise Flight electronic speedbrake STC covers the M20 series, but installation means cutting the wing skins.

What is the main airworthiness issue on the MOONEY M20C?
The FAA has received reports of MOONEY M20C control wheel separations caused by fatigue cracks in the control shaft or wheel attachment hub. It has asked owners to inspect the wheel visually and report any cracks.
How often is the control shaft inspected?
For the MOONEY M20C, the existing AD requires inspection of the aft end of the control shaft every 500 hours TIS. If the shaft was strengthened per Mooney SB M20-205B, the interval is 1000 hours TIS.
Can I get exact MOONEY M20C performance numbers from this guide?
No. The supplied documents give no M20C-specific figures. Family-wide, M20 variants are listed at up to 222 kt cruise, 1050 nm range and 25000 ft ceiling. Those are maxima for the whole family, not the MOONEY M20C itself.
Where do I buy MOONEY M20C parts?
The Mooney parts catalog says parts are available only through authorized Mooney facilities. Give the part number, description, quantity, and the model and serial number of your MOONEY M20C.
What is the MOONEY M20C Model Guide?
The MOONEY M20C Model Guide is a model guide for the MOONEY M20C, dated 2026.

Control wheel and shaft concern
The FAA's September 24, 2024 Airworthiness Concern Sheet covers the M20C, M20D, M20E, M20F and M20G. It reports control wheel separations on M20C aircraft from fatigue cracks in the control shaft or wheel attachment hub. The existing AD inspects the aft end of the shaft, not the control wheel. The FAA asks operators to visually inspect the wheel and to report the attachment method (tapered pin or bolt).
Parts and configuration checks
The Mooney parts catalog covers M20 series aircraft from 1968 models on. Parts marked "C" apply to serial number 680001C and on. Earlier serials need the 1965-1967 catalog. It lists electric and manual gear retraction, and hydraulic and electric flap controls, so confirm which your airplane has. Orders go through authorized Mooney facilities and need the model and serial number.
Speedbrake modification
Precise Flight's 2000 Series electronic SpeedBrake (STC SA4342NM) covers M20 series Mooneys. Installation cuts openings in the top of each wing skin and adds doublers, with rivets removed and replaced. It also needs an asymmetric logic control, a circuit breaker and a cockpit switch. Check logbooks and FAA Form 337 paperwork if one is fitted.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Control wheel separation can cause momentary loss of control until the other pilot regains it with the second wheel. This matters most on takeoff and landing.
- Inspect the control wheel and shaft for cracks before buying. Ask for the AD compliance history and whether the shaft was strengthened per SB M20-205B.
- If a speedbrake is fitted, check that the kit voltage matched the aircraft voltage and that the wing cutouts were reinforced with doublers.
