Aviation Accident Summary NYC97LA050

YORK, PA, USA

Aircraft #1

N42BN

Berry VANS RV-4

Analysis

The pilot/owner of a homebuilt Vans RV-4 airplane flew to his destination airport. He stated that he entered the down wind traffic pattern for landing, and observed an airplane on the taxiway, short of the runway. When he turned from base to final approach, the airplane on the ground taxied onto the runway. The RV-4 pilot elected to do 'S' turns to give the airplane on the runway time to depart, but it remained on the runway, so the RV-4 pilot initiated a go-around. Power was applied, and the wings were leveled, but the airplane continued to descend and contacted the ground. The airplane was damaged during ground contact, but it became airborne again and continued flying. The pilot then landed without further incident.

Factual Information

On February 2, 1997, at 1030 eastern standard time, a homebuilt, Vans RV-4, N42BN, was substantially damaged when it struck the ground during a go-around at the York Airport (THV), York, Pennsylvania. The certificated commercial pilot and passenger were not injured. Visual meteorological conditions prevailed for the personal flight that originated at Westminster, Maryland, about 1000. No flight plan had been filed for the flight conducted under 14 CFR Part 91. In the pilot's written statement, he said that he entered the down wind traffic pattern for landing on runway 34, and observed an airplane on the taxiway, short of the runway. When the pilot turned his airplane from base to final approach, the airplane on the ground taxied onto the runway. He elected to do "S" turns to give the airplane on the runway time to depart, but airplane remained on the runway. The pilot also said: "...Prior to ground impact, I elected to wave off...power was applied...Upon rolling wings level...I felt a left slip and stick shaker...The aircraft began falling, rolling left impacting the ground..." The pilot further stated that during ground impact, full power was applied, and the airplane became airborne. The pilot continued the climb and then completed a successful landing at THV. The pilot stated that he encountered no malfunctions with the airframe or engine.

Probable Cause and Findings

the pilot's delay in initiating a go-around, and his failure to maintain airspeed, which resulted in an inadvertent stall/mush and contact with the terrain.
