# NTSB ANC95LA099: Stinson 108-2, N257C, Anchorage, AK, July 7, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 6, 1995, 21:35 local (Jul 7, 1995, 05:35 UTC) - Place: Anchorage, AK - Coordinates: 61.160175, -149.989105 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=61.1602&lon=-149.9891&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 8, 1996 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 2683 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC95LA099 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/2683/pdf - Page: https://openairdocs.org/ntsb/ANC95LA099 ## Probable cause THE PILOT'S LOSS OF DIRECTIONAL CONTROL, DURING THE TAKEOFF ROLL, WHICH RESULTED IN AN INADVERTENT SWERVE, AND THE PILOT'S EXCESSIVE APPLICATION OF BRAKE PRESSURE, WHICH RESULTED IN A NOSE DOWN CONDITION. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - directional control - not maintained, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command (cause) - Nose down, takeoff - aborted - brakes(normal) - excessive, pilot in command (cause) ## Analysis THE AIRPLANE VEERED TO THE LEFT DURING THE FIRST ATTEMPT TO TAKE OFF. THE PILOT STATED SHE ATTRIBUTED THIS TO WIND GUSTS FROM THE WEST (LEFT). DURING THE SECOND ATTEMPT TO TAKE OFF, THE AIRPLANE VEERED TO THE LEFT AGAIN AND DEPARTED THE LEFT SIDE OF THE RUNWAY, TOWARD SOME PARKED AIRCRAFT. THE PILOT APPLIED THE BRAKES, AND THE AIRPLANE NOSED DOWN. THE WINDS WERE REPORTED TO BE FROM 310 DEGREES AT 4 KNOTS. ## Factual narrative On July 6, 1995, at 2135 Alaska daylight time, a wheel equipped Stinson 108-2 airplane, registered to and operated by the pilot, nosed down during an aborted takeoff from the Lake Hood Airstrip, Anchorage, Alaska. The personal flight, operating under 14 CFR Part 91, was departing the Lake Hood Airstrip for a local flight. A visual flight rules flight plan was filed and visual meteorological conditions prevailed. The private certificated pilot, the sole occupant, was not injured and the airplane received substantial damage. According to the pilot, as she started her takeoff roll on runway 31, the airplane veered to the left. She applied right rudder and stopped the airplane. She taxied back for a second takeoff on runway 31. During the second takeoff the airplane veered to the left again. She applied right rudder but also had to step on the brakes because the airplane was headed for some parked airplanes. The airplane nosed down as it came to a stop. The pilot stated there were wind gusts blowing across runway 31 from the west (left) during the takeoff roll. The reported winds at the Lake Hood Airstrip were from 310 degrees at 4 knots. ## Aircraft - Registration: [N257C](https://openairdocs.org/aircraft/N257C), registered now, S/N 108-3257 (OpenAirDocs) - Reported make and model: STINSON 108-2 - Registry model: [Universal Stinson 108-2](https://openairdocs.org/model/universal-stinson-108-2) (registry code 9230416) (OpenAirDocs) - Registry engine: [Franklin 6A4165 series](https://openairdocs.org/engine/franklin-6a4165-series) (registry code 27025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-3257 - Airframe hours: 2635 - Engines: FRANKLIN 6A4-165B3 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Metcalf, Susan K. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 18, 1994, 15 hours before - Departed: Z41 - Flight plan: VFR - Airport: Z41, Lake Hood Airstrip, runway 31, 2,200 × 70 ft, gravel ## Flight crew As NTSB recorded them.

Lost directional control on two attempts to takeoff. Used heavy braking to avoid exiting runway. Nosed up. 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.
