Aircraft Collides With Runway Sign Following Bounced Landing (N402KT)

San Carlos, CA, US

On November 21, 1995, a Diamond Aircraft Industries DA20-A1 (registration N402KT) operated by Diamond Aviation was involved in an aviation accident near San Carlos, CA. Investigators recorded the probable cause as: The pilot's failure to maintain control during the landing roll after a bounced touchdown, which resulted in the aircraft veering off the runway and colliding with a sign. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.

After multiple landing attempts and a go-around, the aircraft touched down hard, bounced, veered off the runway, and struck a sign during calm wind conditions.

What happened

The pilot initiated an approach to land at the airport under calm wind conditions. The local air traffic controller observed that the initial approach appeared to be flown at excessive speed. Consequently, the pilot executed a go-around for the first attempt. A second landing attempt followed the same pattern, with the controller again noting a fast approach profile, leading to another go-around.

On the third approach, the aircraft successfully touched down on the runway. However, upon impact, the aircraft bounced several times. Following the bounces, the pilot lost directional control, causing the aircraft to veer off the paved surface. The aircraft then collided with a runway sign located near the edge of the runway.

The investigation

Post-incident inspection revealed damage consistent with the collision with the ground and the signage. The pilot reported that there were no mechanical problems with the aircraft prior to or during the incident. Weather conditions at the time of the accident were calm, eliminating wind shear or crosswind as contributing factors.

Findings

The sequence of events indicates a loss of control after touchdown due to a bounced landing. The repeated go-arounds suggested difficulty in maintaining proper approach speed and descent rate. The final collision was a direct result of the aircraft leaving the runway surface after the bounce.

Probable cause

The pilot's failure to maintain control during the landing roll after a bounced touchdown, which resulted in the aircraft veering off the runway and colliding with a sign.
