NTSB Identification: CEN13CA142
14 CFR Part 91: General Aviation
Accident occurred Wednesday, January 23, 2013 in Peoria, IL
Probable Cause Approval Date: 06/19/2013
Aircraft: CESSNA 172S, registration: N5113J
Injuries: 2 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

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.
