Probable cause

The pilot’s inadvertent activation of the electric trim to the nose-down position, which resulted in the airplane being improperly configured for takeoff, and the flight instructor’s incorrect remedial action that allowed the airplane to porpoise.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The private pilot reported that during the takeoff, shortly after rotation, the airplane’s nose pitched downward and the airplane bounced on the runway. He stated that after the first bounce, the flight instructor took control and that the airplane bounced several more times before coming to rest on its nose. The flight instructor reported that preflight and pretakeoff checks were performed, no airplane deficiencies were noted, and the elevator trim was set for takeoff. He added that he took control after the first bounce and attempted to abort the takeoff. The airplane bounced violently four or five more times. The flight instructor attempted to stop the airplane by retarding the throttle, applying up elevator for aerodynamic braking, and trying to keep the nosewheel off of the ground. The airplane’s nose landing gear had collapsed and the firewall and fuselage had sustained damage. Although the flight instructor said that the elevator trim was set for takeoff, postaccident examination of the airplane revealed that the elevator trim was in the full nose-down position. Although it could not be definitively determined, it is likely that the pilot inadvertently actuated the electric trim switch on the yoke before takeoff. Examination of the airplane's control system revealed no anomalies that existed before the accident that would have precluded normal operation.

Factual narrative

The private pilot reported that after the airplane rotated for takeoff, the nose pitched downward and the airplane bounced on the runway. He stated that after the first bounce, the flight instructor took control and the airplane bounced several more times before coming to rest on its nose. The flight instructor reported that pre-flight and pre-takeoff checks were performed, no airplane deficiencies were noted, and the elevator trim was set for takeoff. He added that he took control after the first bounce and attempted to abort the takeoff. The airplane bounced violently four or five more times as he attempted to stop the airplane by retarding the throttle, applying up elevator for aerodynamic braking, and trying to keep the nosewheel off of the ground. Examination of the airplane after the accident revealed that the elevator trim was in the full nose down position. The airplane’s nose landing gear had collapsed and the firewall and fuselage had sustained damage. The lower portion of the fuselage/firewall was pushed rearward into the pilot compartment displacing the rudder pedals. Tests of the elevator trim system revealed no anomalies. Examination of the airplane's control system revealed no anomalies that existed prior to the accident. Federal Aviation Administration publication FAA-H-8083-3A, “Airplane Flying Handbook” stated the following in regard to recovery from a bounced landing: “The corrective action for a bounce is the same as for ballooning and similarly depends on its severity. When it is very slight and there is no extreme change in the airplane’s pitch attitude, a follow-up landing may be executed by applying sufficient power to cushion the subsequent touchdown, and smoothly adjusting the pitch to the proper touchdown attitude.”
