On 31 May 2008, a Piper Seneca operated by William M. Nuttall was involved in an aviation accident near Plaquemine, LA. No fatalities were reported. Investigators recorded the probable cause as: The certified flight instructor's poor decision to simulate a loss of engine on takeoff with a wet runway and the pilot's failure to maintain directional control. Contributing to the accident was the dew covered runway surface and the ditch. This summary draws on records from NTSB.
During an instructional takeoff from a dew-wet grass strip, a CFI simulated engine failure; the pilot aborted, but the aircraft slid off the runway into a ditch, causing structural damage.
Accident
The private pilot reported to FAA personnel that he was on an instructional flight with a certified flight instructor. The takeoff was being conducted from a 2600-foot-long by 80-foot-wide grass airstrip, which was wet with dew. During the initial takeoff roll at approximately 40 knots, the flight instructor pulled the left throttle to idle to simulate the loss of an engine. In response, the pilot aborted the takeoff by pulling the right throttle back and applying the wheel brakes. The airplane subsequently slid off the side of the runway into an adjacent field and struck a ditch.
Aircraft Damage
Examination of the airplane following the accident revealed that the left wing had pulled forward, separating the trailing edge from the fuselage by approximately 1.5 inches and buckling the fuselage at the leading edge. No other damage was noted or reported.
