The pilot misjudged altitude due to night optical illusion, resulting in a hard landing, multiple bounces, and propeller strike. No injuries reported.

Incident Overview

During a night landing, the aircraft contacted the runway earlier than anticipated. The touchdown was hard, causing the airplane to bounce several times. During the bounces, the propeller blades struck the runway surface. The airplane eventually came to rest upright on the pavement.

Sequence of Events

The pilot was setting up for a flare when the airplane hit the runway hard. The impact initiated a series of bounces. After each bounce, the aircraft settled back onto the runway, striking the propeller blades on successive contacts. The aircraft remained upright and came to a stop on the runway.

Pilot's Explanation

The pilot reported that night conditions, the narrow runway width, and the upsloping terrain created a night optical illusion. This caused her to perceive the airplane as being higher than its actual altitude. Believing she was at a proper flare height, she initiated the flare, but the airplane was lower than expected, resulting in the hard touchdown.

Probable cause

The pilot's misjudgment of altitude due to night optical illusion, leading to a hard landing and subsequent bounce.
