What happened
The pilot of a Piper PA-28 was positioned on the ramp behind a Socata Tampico TB-9C, identified by registration N2816D. Both aircraft were stationary, waiting for takeoff clearance from air traffic control. The Piper remained stopped directly behind the Socata.
At some point during this wait, the Piper pilot diverted his attention to a notepad held in his lap or hand. During this distraction, he inadvertently released pressure on the brake pedals. Without realizing it, the Piper began to roll forward slowly. The aircraft moved closer to the Socata until its propeller made contact with the left horizontal stabilator of the plane ahead.
The pilot of the Piper later reported that he did not notice the movement of his aircraft until after the impact occurred. He attributed the incident to a lapse in attention while reviewing notes, which led to the unintended release of braking force.
The investigation
Examination of the accident site revealed damage to the left horizontal stabilator of the Socata Tampico TB-9C caused by contact with the propeller of the Piper PA-28. No other structural damage was reported for either aircraft beyond this specific point of impact. The investigation focused on the actions of the pilot and the sequence of events leading to the collision.
Findings
The primary factor in this incident was the pilot's failure to maintain proper brake pressure while distracted. The lack of attention to the aircraft's status allowed it to move uncontrolled. This highlights the importance of situational awareness even when stationary on the ground, particularly in congested ramp areas where other aircraft are nearby.
Safety message
Pilots must maintain constant vigilance over their braking systems, especially during periods of waiting or distraction. Diverting attention from the aircraft's controls can lead to unintended movement and potential collisions with other aircraft.
