# NTSB SEA96LA066: Cessna 150F, N8920S, Eugene, OR, March 9, 1996 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: March 9, 1996, 15:21 local (23:21 UTC) - Place: Eugene, OR - Coordinates: 44.039825, -123.219093 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=44.0398&lon=-123.2191&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report February 28, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 42343 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA96LA066 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/42343/pdf - Page: https://openairdocs.org/ntsb/SEA96LA066 ## Probable cause the student pilot's inadvertent activation of the brakes and his failure to maintain directional control, which resulted in an inadvertent ground swerve. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - brakes(normal) - inadvertent activation, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command (cause) - Gear collapsed, landing - roll - landing gear,nose gear - overload - Nose over, landing - roll ## Analysis The student pilot, with a total of 14 hours of flight experience, was executing his first solo landing to runway 21 in calm wind conditions. He reported that the aircraft 'turned sharply to the right' during the landing roll and he was unable to regain directional control. The aircraft subsequently departed the runway during which the nose landing gear collapsed and the aircraft nosed over. Wheel skid marks of 283 feet were measured on the runway, and no mechanical malfunction with the aircraft's brakes was found. The student pilot's instructor, who witnessed the accident, postulated that the student inadvertently actuated the brakes during the landing. ## Factual narrative On March 9, 1996, at 1521 Pacific standard time, a Cessna 150F, N8920S, registered to Aerial Communications of America, Inc., a Part 141 flight school, and being flown by a student pilot with approximately 14 hours of total flight time, was substantially damaged during a loss of control and nose over while landing on runway 21 at the Mahlon Sweet Field, Eugene, Oregon. The pilot sustained minor injuries. Visual meteorological calm wind conditions existed and no flight plan had been filed. The flight, which was to have been the student's first instructional solo operated under 14CFR91, originated from the airport approximately 1518. An FAA Inspector, who interviewed the pilot subsequent to the accident, reported that the aircraft touched down in the first 700-800 feet of runway 21, and 47 feet right of the centerline. The inspector reported that the student pilot attempted to correct with left rudder during which the right wing lifted. The pilot then added power and the aircraft began to skid left leaving wheel skid marks for 283 feet during which the right wingtip impacted the runway. The aircraft then departed the east side of the runway, the nose wheel partially collapsed, and the aircraft nosed over. The student pilot reported that his first approach and touchdown to runway 21 was normal but that "then, the plane turned sharply to the right." The student attempted to compensate with power and left rudder during which the aircraft departed the runway. His instructor, who with other witnesses, observed the accident reported that he was "amazed to watch the aircraft veer out of control following a well-stabilized approach" and postulated that the student pilot "may have positioned his feet high enough on the rudder pedals to actuate the brakes causing his swerve." There was no reported mechanical malfunction of the aircraft's brakes. ## Aircraft - Registration: [N8920S](https://openairdocs.org/aircraft/N8920S), registered now, S/N 15062220, built 1965 (OpenAirDocs) - Reported make and model: Cessna 150F - Registry model: [Cessna 150F](https://openairdocs.org/model/cessna-150f) (registry code 2071814) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15062220 - Airframe hours: 1556 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Aerial Communications Of Ameri - Airworthiness certificate: Standard, Utility - Last inspection: 100 hour, February 2, 1996, 57 hours before - Departed: EUG - Airport: EUG, Mahlon Sweet Field, runway 21, 5,221 × 150 ft, asphalt ## Flight crew As NTSB recorded them.
