Accident Detail
A private pilot without an instrument rating initiated a night visual flight rules (VFR) departure from a sparsely populated airfield located adjacent to water. The flight occurred under VFR conditions; however, no natural horizon or surface reference was available to the pilot. The moon was below the horizon with an elevation of -43.7 degrees and only 7% illumination, providing minimal ambient light. No flight plan was filed prior to departure.
Witness Observations
Witnesses on the ground observed the airplane climb to an altitude between 125 and 300 feet above ground level (AGL) during a right crosswind departure. The aircraft then leveled off briefly. Subsequently, the airplane entered a left turn while descending with a nose-down attitude of approximately 20 degrees and the right wing lowered. The engine was heard running throughout the maneuver. The aircraft continued its descent and struck the water surface.
Subsequent Events
Following the collision with the water, the airplane was destroyed. The investigation did not identify any mechanical malfunctions or failures. The pilot's noninstrument rating and the lack of visual references in the dark conditions over water were noted as relevant to the accident sequence. No further causal factors were determined.
