# NTSB NYC95LA008: Beech A36, N601AV, Amityville, NY, October 12, 1994 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: October 12, 1994, 12:27 local (16:27 UTC) - Place: Amityville, NY - Coordinates: 40.659133, -73.409904 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.6591&lon=-73.4099&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report January 19, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 38884 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC95LA008 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38884/pdf - Page: https://openairdocs.org/ntsb/NYC95LA008 ## Probable cause The loss of engine power for undetermined reasons. Also causal was the inspector's improper inflight decision to simulate an emergency beyong the gliding distance to a suitable landing area. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, approach - vfr pattern - downwind - reason for occurrence undetermined (cause) - in-flight planning/decision - improper, faa inspector (cause) - emergency procedure - improper, faa inspector - Forced landing, descent - emergency - On ground/water encounter with terrain/water, landing - terrain condition - ravine - unsuitable terrain or takeoff/landing/taxi area ## Analysis The pilot was receiving a re-examination checkride by a FAA inspector when the accident occurred. The flight was conducted in the traffic pattern for runway 01 at Republic Airport (FRG) for the purpose of doing touch-and-go landings on runway 01. While on base leg, the inspector simulated a loss of engine power by retarding the throttle. The pilot stated that he did the emergency procedure for the loss of power, and when he was instructed to advance the power, the engine did not respond. The pilot reported that the fuel pressure gage was indicating in the green arc range. The inspector turned the auxiliary fuel pump on, but the loss of power continued. The inspector took control of the airplane and did a forced landing into a reservoir. The examination of the airplane did not disclose evidence of mechanical malfunction. The airplane was placarded to takeoff and land with aux fuel pump off, except in case of loss of fuel pressure. The approved airplane flight manual indicates the emergency procedure for loss of engine power is to check the fuel flow gage and if fuel is abnormally low to turn the aux fuel pump on then off if performance does not improve in a few moments. ## Factual narrative On October 12, 1994 about 1227 eastern daylight time, N601AV, a Beech A36 airplane, lost engine power and was forced landed at Amityville, New York. Visual meteorological conditions existed. The certificated private pilot and the FAA Inspector were seriously injured. The airplane was substantially damaged. The flight originated at Republic Airport, Farmingdale, New York. The flight was operated under 14 CFR Part 91. The pilot was receiving a re-examination checkride by the FAA Inspector when the accident occurred. The pilot and inspector were conducting flight in the traffic pattern for runway 01 at Republic Airport. The inspector retarded the throttle to simulate a loss of engine power and afterward the throttle was advanced to increase power, but the engine did not respond. The inspector took control of the airplane and he did a forced landing in a reservoir located in a residential area, about 0.5 mile southeast of the runway. According to the pilot, the airplane was on extended downwind to the runway, just turning base leg at approximately 900 feet, when the inspector closed the throttle to idle. The pilot stated he observed manifold pressure drop below the green arc, and he started doing engine failure procedures and headed directly for the airport. He realized that he would not make the airport, so he decided to add power. The engine did not respond to throttle movement, and the inspector took controlof the airplane. The pilot reported that he switched fuel tanks per the inspector's instruction. The pilot stated that the inspector turned the fuel pump on, although the fuel pressure was in the green arc. He stated the inspector "put the aircraft into a stall and crashed the aircraft." According to the FAA inspector, when he retarded the throttle, he felt the airplane was within gliding distance to the airport. When he realized the engine power could not be restored and he took control of the airplane. He indicated that he activated the fuel boost pump, but he does not recall what the fuel pressure was beforehand. The airplane was examined at the accident site by the FAA on October 12, 1994; the airplane was examined by the NTSB at Republic Airport on October 18, 1995. The FAA examination determined the fuel boost pump switch was in the "on" position. The engine examination confirmed drive train continuity, magneto sparking, spark plug operation, fuel in the lines to the fuel manifold distributor valve, cylinder compression, and attachment of powerplant controls between the throttle quadrant to the applicable engine mounted accessories. Also, a visual check was negative for the presence of water contamination. Evidence of mechanical malfunction was not disclosed during the examination. According to the FAA approved Airplane Flight Manual (AFM) for the Beech A-36 airplane the following, in part, is stated for the auxiliary fuel pump: The electric auxiliary fuel pump is controlled by the ON- OFF toggle switch on the control console and provides pressure for starting and emergency operation. Immediately after starting, the auxiliary fuel pump can be used to purge the system of vapor caused by an extremely high ambient temperature or a start with the engine hot. The auxiliary fuel pump provides for near maximum engine fuel requirements, should the engine driven pump fail. According to the AFM, the airplane is to be placarded to state in part: AUX FUEL PUMP OPERATION Take-Off and Land With Aux Fuel Pump Off Except In Case Of Loss of Fuel Press The emergency procedures stated in the AFM for loss of engine power states, in part, the following: 1. Fuel Flow Gage - Check If fuel flow is abnormally low: a. Mixture - Full Rich b. Auxiliary Fuel Pump - On (then Off if performance does not improve in a few moments) ## Aircraft - Registration: [N601AV](https://openairdocs.org/deregistered/N601AV-1997-03-17), registration cancelled 1997-03-17, S/N E1763 (OpenAirDocs) - Reported make and model: BEECH A36 - Registry model: [Beech A36](https://openairdocs.org/model/beech-a36) (registry code 1151604) (OpenAirDocs) - Category: Airplane - Serial number: E-1763 - Airframe hours: 1628 - Engines: CONTINENTAL IO-520 285 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Operator: Flightways - Registered owner: Aircraft Leasing Inc. - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, September 13, 1994, 100 hours before - Departed: FRG, FARMINGDALE, NY - Airport: FRG, Republic Airport, runway 19, asphalt ## Flight crew As NTSB recorded them.

Check ride. Instructor cut power to FAR out. No engine response. Used fuel boost and flooded engine. Landed in lake From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
