Ignition Switch Issues
The student pilot was doing an engine run prior to flight. Was unable on the first try to complete the magneto check as the key would not turn from the both position to the left/right/off position. After shutdown, the student was able to select off on the switch. The switch that was installed (p/n 103572101) included a push-to-start function. Found the switch sticking internally and replaced it with a new push-to-start switch.
Key Takeaways:
- Aircraft ignition switches frequently experience mechanical failures such as sticking, difficulty turning, or engaging the starter incorrectly.
- Electrical malfunctions are also common, including intermittent grounding causing engine roughness or switches overheating and emitting smoke.
- These failures affect various aircraft models (Cessna, Diamond, Grob, Piper) and lead to operational issues like failed engine starts, incomplete magneto checks, or unintended starter engagement.
