What happened
The aircraft was being taxied for takeoff when its left wing struck the nose of a parked Piper Twin. The pilot reported that he was performing his standard instrument scan during the taxi phase. During this scan, he noticed that the alternator gauge failed to indicate a charging state.
This mechanical anomaly appears to have drawn the pilot's focus away from the external environment. Consequently, he lost situational awareness regarding his precise position on the taxiway. At the time of the incident, wind conditions were challenging, with gusts estimated at 30 knots. The combination of the distraction caused by the electrical system indication and the high winds contributed to the loss of lateral control necessary to avoid the stationary aircraft.
The investigation
The primary finding from the pilot's statement was the correlation between the alternator failure indication and the lapse in spatial awareness. No further mechanical examination details were provided in the source text regarding the parked Piper Twin or the specific electrical system status beyond the gauge reading.
Findings
The incident highlights how internal cockpit distractions can compromise external situational awareness, particularly during ground operations. The pilot's attention was fixed on the instrument panel due to the unexpected electrical system anomaly, leading to a failure to monitor the aircraft's position relative to nearby obstacles. The gusty wind conditions likely exacerbated the difficulty in maintaining precise taxiway alignment.
