Hello All
We were 2-3 minutes from taking off in our Mooney M20E when the engine suddenly quit. It recovered briefly when the throttle was pulled back halfway, but then quit for good. Successful off-field landing; no injuries; no damage.
Full tanks, both sumped 45 minutes after fueling. Full-power runup before takeoff revealed no anomalies. Fuel selector on left tank; boost pump on throughout the episode. Mixture rich. Field elevation 2,000 feet. Altitude when engine failed about 3,500 feet.
Post-incident inspection shows good fuel flow from both tanks, good operation of fuel selector valve. Hoses from pump to servo secure, hose from servo to injection distributor secure. Only defect is missing full-rich stop on fuel injection servo. We’re having the servo rebuilt, but we’re not confident that’s the problem. Engine ran strong during prior 10hr X/C.
Any ideas?
