# NTSB ATL95LA175: Schweizer 269C, N267RW, Hoover, AL, September 27, 1995 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: September 27, 1995, 17:11 local (22:11 UTC) - Place: Hoover, AL - Coordinates: 33.469871, -86.809471 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=33.4699&lon=-86.8095&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report April 18, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 3629 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL95LA175 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/3629/pdf - Page: https://openairdocs.org/ntsb/ATL95LA175 ## Probable cause The pilot's failure to maintain directional control when he positioned the helicopter in a hover so as to induce a loss of tail rotor effectiveness. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, hover - rotor system,tail rotor - stall (cause) - tail rotor effectiveness - not maintained, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis The flight departed Birmingham airport with a VFR clearance for a local photo shoot. The helicopter was flying above a ridge line and made a right turn into a hover. At this point it began to rotate to the right about the main rotor shaft, and spiraled to the ground. The pilot stated that there was no mechanical malfunction, and the helicopter had lost tail rotor effectiveness. Examination of the wreckage revealed that the tail rotor drive shaft had broken in overload. ## Factual narrative On September 27, 1995, about 1711 central daylight time, a Schweizer 269C, N267RW, collided with the ground during an uncontrolled descent from a hover near Hoover, Alabama. The helicopter was operated by Rotor Wing, Inc., under the provisions of 14 CFR Part 91, and visual flight rules. Visual meteorological conditions prevailed. A flight plan was not filed for the photographic flight. The pilot and his passenger sustained serious injuries, and the helicopter was substantially damaged. Origination of the flight was Hayden, Alabama, at an unspecified time. According to the operator, the pilot stated that there were no mechanical malfunctions of the helicopter. Witnesses observed the helicopter flying alongside a ridge line. The helicopter slowed, made what was described as a pedal turn to the right, and entered a hover, out of ground effect. As it stopped, the helicopter "rocked laterally," began to rotate about the main rotor shaft, then transitioned into a descending right spiral and impacted the ground. The pilot later stated that he had gotten into a hover and lost tail rotor effectiveness. The examination of the wreckage revealed that there was fuel on board, in both tanks. Flight control continuity was found to the mast, and the tail rotor drive shaft had snapped. The throttle was closed, magnetos on both, the mixture full rich, the master switch was "off" (turned off by rescue), the fuel valve was on, the clutch was on, and the fuel boost pump was on. Only pages 1 and 2 of the Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1/2, were received. ## Aircraft - Registration: [N267RW](https://openairdocs.org/aircraft/N267RW), registered now, S/N 0047, built 1964 (OpenAirDocs) - Reported make and model: SCHWEIZER 269C - Registry model: [Hughes 269B](https://openairdocs.org/model/hughes-269b) (registry code 4470502) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Helicopter - Serial number: 1351 - Airframe hours: 978 - Engines: LYCOMING HI0-360D1A 190 horsepower reciprocating - Damage: Substantial damage - Flight: Other work use, Part 91 - Registered owner: Rotor Wing, Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 12, 1995, 28 hours before - Departed: NONE, HAYDEN, AL ## Flight crew As NTSB recorded them.

Lost tail rotor effectiveness in hover near a ridge line. Had made pedal turn. Rocked. Spiraled to impact. 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.
