Probable cause
Improper operation of the cyclic by the student pilot, failure of the student to relinquish control and inadequate supervision by the flight instructor.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During a instructional flight, the flight instructor directed the student to make a normal takeoff. The instructor was following the student on the controls when the student suddenly moved the cyclic to the left. The helicopter started to roll to the left. The instructor could not overpower the student and regain control before the helicopter rolled over on its left side. There were no noted mechanical failures or malfunctions with the helicopter.
