Aircraft Accident/Incident Report

East Hampton, New York 11937
Wednesday, October 6, 1993 12:35 EDT

NTSB Narrative Summary Released at Completion of Accident

THE FLIGHT, INVOLVING AN INSTRUCTOR AND STUDENT, CRASHED IN A WOODED AREA ABOUT A MILE SOUTHEAST OF RUNWAY 28 AT EAST HAMPTON AIRPORT. THE PILOT RADIOED 10 MILES WEST OF THE AIRPORT, REQUESTED, AND RECEIVED AIRPORT ADVISORIES. NO OTHER KNOWN RADIO CALLS WERE MADE BY THE PILOT. A WITNESS NEAR THE ACCIDENT SITE, FIRST HEARD AN AIRPLANE; LATER, HE HEARD THE ENGINE SOUNDS STOP. AFTER ABOUT ANOTHER 40 SECONDS, HE HEARD THE SOUND OF A CRASH. AN INVESTIGATION REVEALED THAT BOTH PROPELLERS WERE FEATHERED; AN EXAMINATION OF THE AIRPLANE DID NOT DISCLOSE EVIDENCE OF MECHANICAL MALFUNCTION. THE STUDENT WAS A 3500 HOUR COMMERCIAL CERTIFICATED PILOT WHO WAS TRAINING FOR A MULTIENGINE RATING. THE INVESTIGATION ALSO REVEALED THAT ON PREVIOUS TRAINING FLIGHTS, THE STUDENT HAD DEMONSTRATED A LACK OF PROFICIENCY IN THE PERFORMANCE OF SIMULATED INSTRUMENT AND EMERGENCY PROCEDURES. ALSO, THE INVESTIGATION REVEALED THAT THE STUDENT HAD PREVIOUSLY FLOWN A BEECH 95, WHICH HAD REVERSE PLACEMENT OF THROTTLES, PROPS, AND MIXTURE CONTROLS.

NTSB Probable Cause Narrative

INADVERTENT FEATHERING OF BOTH PROPELLERS BY THE STUDENT PILOT, WHICH RESULTED IN A LOSS OF POWER, AND FAILURE (OR INABILITY) OF THE INSTRUCTOR PILOT (CFI) TO ATTAIN REMEDIAL ACTION. A FACTOR RELATED TO THE ACCIDENT WAS: THE STUDENT PILOT'S HABIT INTERFERENCE, CONCERNING THE DIFFERENT POSITION OF THE ENGINE CONTROLS IN THIS AIRPLANE, AS COMPARED THE THE PREVIOUS AIRPLANE THAT HE HAD FLOWN.
