What happened
The pilot of a Piper PA-32, registered as N4143W, initiated a takeoff roll toward the west-northwest on a tidal beach. Simultaneously, another pilot was taxiing west onto the same beach in a high-wing Bellanca 7GCBC, registration N2677Z. The Bellanca was angling down from a higher area of soft sand onto a lower section of hard-packed sand.
Visibility issues played a critical role in the sequence of events. As the Bellanca pilot taxied down the slope, his view to the left rear was obstructed by his own left wing. Concurrently, the Piper pilot’s right forward view was restricted by the aircraft's nose during the takeoff roll. Shortly after the Piper PA-32 lifted off, its right wingtip struck the left wing and propeller of the Bellanca 7GCBC. The Piper pilot aborted the takeoff immediately and brought the aircraft to a stop after traveling an additional 300 to 400 feet.
The investigation
The physical evidence confirmed that the collision occurred between the right wingtip of the Piper PA-32 and the left wing and propeller assembly of the Bellanca 7GCBC. The location of the damage was consistent with the reported trajectory of the Piper aircraft as it departed the surface while the Bellanca was positioned on the beach below.
Findings
The primary contributing factors were the restricted visibility for both pilots due to their respective aircraft configurations and positions, combined with the lack of visual contact between the two aircraft during critical phases of ground movement and initial flight. The Piper pilot's inability to see the Bellanca ahead, and the Bellanca pilot's inability to see behind him, resulted in the collision despite both pilots being active on the beach.
Safety message
Operations on unprepared surfaces such as tidal beaches require heightened situational awareness. Pilots must account for restricted visibility angles inherent to their aircraft design and ensure positive visual separation from other ground or air traffic before initiating takeoff or taxiing maneuvers.
