What happened
The pilot was operating a privately owned Cessna 172P aircraft for a cross-country flight. During the operation, the pilot reported experiencing an engine failure after flying for approximately 4.7 hours. Following the loss of power, the pilot attempted to land the aircraft. During the landing roll, the nose gear collapsed due to the rough terrain at the site of impact.
The investigation
Recovery personnel examined the aircraft following the incident. A thorough inspection revealed that no fuel was present in the aircraft's fuel tanks or fuel lines during the recovery process. Despite the lack of fuel found on site, mechanics performed a test run on the engine. The engine was observed to run satisfactorily during this post-incident evaluation.
Findings
The investigation highlighted several key factors contributing to the outcome of the event. The primary mechanical issue involved the structural failure of the nose gear under the stress of rough terrain contact. Additionally, the complete absence of fuel in the tanks and lines was a significant finding, although the engine's ability to run satisfactorily during testing suggests that the initial failure may not have been caused by a permanent internal mechanical defect.
Safety message
Pilots operating aircraft for extended durations should remain vigilant regarding fuel management and potential engine anomalies. Regular pre-flight inspections and post-incident evaluations are critical for determining the root cause of unexpected failures.
