Incident Overview
While in cruise flight, the pilot detected an abnormal noise emanating from the left side of the engine compartment. Citing prior problems with the recently installed engine, the pilot decided to perform a precautionary landing at a nearby airport to investigate the source of the sound.
Landing and Excursion
The pilot reported that the landing was long. After touchdown, the aircraft was unable to stop before departing the end of the prepared runway surface. The subsequent terrain beyond the runway was rough, leading to substantial damage to the undercarriage attachment fitting.
Damage Assessment
Inspection revealed that the undercarriage attachment fitting sustained substantial damage as a direct result of the aircraft traversing rough terrain after the runway overrun. No other damage or injuries were noted in the available report.
Conclusion
The incident occurred during a precautionary landing prompted by an abnormal engine sound. The aircraft's inability to stop within the runway confines resulted in a runway excursion and subsequent structural damage.
