Event Location
Probable Cause
The airplane’s collision with a submerged object during landing, which resulted in a nose-over.
Full Narrative
The certified flight instructor (CFI) stated that the purpose of the flight was to practice glassy water landings. After taking off from Spitfire Aerodrome, 7N7, they flew to the Philadelphia Seaplane Base practice area and overflew the area to check the condition of the river. The CFI stated that there were “no obstacles or debris visible.” Shortly after touchdown, both pilots reported hearing a loud bang, and the airplane immediately nosed over. Both pilots exited the submerged airplane and sustained minor injuries. According to the Federal Aviation Administration inspector-in-charge, the wreckage showed damage consistent with striking a submerged object and the landing was performed in the correct configuration. The airplane incurred substantial damage to its canopy, hull, and tail.
