Pilot Loses Directional Control During Short Field Takeoff (N4506Z)

Bally, PA, US

On April 29, 1998, a Piper PA-28-181 (registration N4506Z) was involved in an aviation accident near Bally, PA. Investigators recorded the probable cause as: failure of the pilot to maintain directional control of the airplane during the takeoff roll; and/or his failure to abort the takeoff, while there was sufficient space available to do so without hitting trees.

During a short field takeoff with flaps set at 25 degrees, the pilot rotated at 50 knots but the airplane failed to become airborne. Relaxing right rudder input led to a left runway departure and collision with trees.

Accident Description

An airplane attempted a short field takeoff. The pilot set the trailing edge wing flaps to 25 degrees and initiated the takeoff roll. Rotation was performed at 50 knots. When the airplane did not become airborne, the pilot relaxed the right rudder input but did not reduce engine power. Subsequently, the airplane departed the runway on the left side and struck trees.

Pilot's Actions

The pilot later recounted that during the takeoff roll, the airplane failed to lift off after rotation. In an effort to correct the situation, he eased off the right rudder pedal while keeping the throttle at takeoff power. This action resulted in a loss of directional control, causing the airplane to veer left off the runway surface and into trees.

Post-Accident Comments

In post-accident statements, the pilot indicated that proper procedure would have been to maintain directional control by holding right rudder, close the throttle, and apply the brakes to bring the airplane to a stop. He acknowledged that these steps were not taken during the incident.
