What happened
The incident occurred during nighttime operations when the pilot was taxiing toward a hangar. The surface of the ramp had been recently resurfaced and lacked any painted taxi lines, removing standard visual cues for navigation. The parking area was described as being very dark, further complicating visibility.
During the maneuver, the left wing of the accident airplane struck an aircraft that was already parked on the ramp. This impact caused significant structural damage to the wing assembly.
The investigation
Post-accident examination revealed that three of the ribs within the left wing structure were bent as a result of the collision. No other mechanical failures or pre-existing conditions were cited as contributing factors in the narrative provided.
Findings
The pilot reported in a subsequent telephone conversation that he had been awake since approximately 0430 that morning. This extended period of wakefulness, combined with the lack of taxiway markings and low-light conditions on the freshly paved surface, contributed to the loss of situational awareness necessary for safe ground maneuvering.
Safety message
Operators should ensure adequate rest periods before flight duties, particularly when operating in low-visibility or unmarked environments. Taxiway markings and adequate lighting are critical safety features that should be maintained to prevent ground collisions.
