Aircraft Accident/Incident Report

East Troy, Wisconsin 53120
Saturday, January 22, 2000 9:45 CST

NTSB Narrative Summary Released at Completion of Accident

According to the CFI's written statement, they were practicing a running takeoff on runway 18 and after traversing approximately ten feet of the takeoff run the student applied right pedal input. The CFI stated that he tried to overcome the student's right pedal input by depressing the left pedal input and verbally commanding the student to do the same. The CFI reported that he was unable to counteract the students control input and the aircraft yawed to the right. The left skid of the helicopter impacted the terrain, the aircraft rolled onto its left side and slid 15-feet before coming to rest.

NTSB Probable Cause Narrative

The proper alignment not being maintained by the dual student during an attempted running takeoff and the inadequate supervision of the pilot-in-command (CFI).
