Accident Sequence
A seaplane was on approach to Avalon on Santa Catalina Island under marginal weather conditions characterized by low clouds and fog. The pilot initiated a go-around after observing boat wakes. During the maneuver, the seaplane stalled, lost altitude, and crashed into the sea several hundred yards off Pebbly Beach.
Injuries
The pilot and two passengers sustained serious injuries. Seven other occupants suffered minor injuries. One passenger drowned.
Official Findings
The probable cause of the accident was a stall during a go-around after the pilot misjudged distance, speed, and altitude. Contributing factors reported by investigators included failure to maintain flying speed, low ceiling, fog, visibility two miles or less, a low altitude straight-in approach toward a seaplane ramp, and the decision to execute a go-around after noticing boat wakes.
