Probable cause
The mixture control cable disconnected from the cable housing attach clamp, which resutlted in the pilot's inability to add power when needed.
NTSB narrative
The pilot reduced power for landing because the approach was slightly high. When he added power to arrest the descent, the engine failed to respond. The airplane landed short of the runway. The impact drove the main landing gear through the right wing. Examination and functional testing of the engine revealed that the mixture control cable was disconnected from the cable housing attach clamp. The cable was reattached and the engine functioned normally with no anomalies noted.
Analysis
- Primary failure mode
- Mechanical failure
- First missed decision gate
- Pilot could have maintained power instead of reducing it while high on approach.
