What happened
The private pilot initiated takeoff from a water surface toward rising terrain under conditions characterized by strong, gusty winds. The available takeoff distance was limited to approximately one mile. As the aircraft approached the shoreline, it had only reached an altitude of about 60 feet above the water.
During this phase of flight, the pilot encountered a downdraft that exceeded the airplane's climb capability. Consequently, the aircraft crashed into the water approximately one-quarter mile past the shoreline.
The investigation
The investigation focused on the circumstances surrounding the takeoff and the subsequent loss of altitude. Key factors included the limited takeoff distance available, the environmental conditions at the time of departure, and the performance limitations of the aircraft relative to the encountered weather phenomena.
Findings
Several contributing factors were identified in the accident narrative:
- The pilot elected to take off from a water surface toward rising terrain with strong gusty winds present.
- The available takeoff distance was approximately one mile.
- The aircraft reached only about 60 feet above the water when approaching the shoreline.
- A downdraft exceeded the airplane's climb capability, leading to the crash approximately one-quarter mile past the shoreline.
Safety message
Pilots operating in areas with rising terrain and strong gusty winds must carefully evaluate available takeoff distances and aircraft performance capabilities. Encountering a downdraft that exceeds climb capability can lead to a loss of altitude, particularly during the critical initial phase of flight near shorelines or obstacles.
