# NTSB SEA00LA029: Cessna 140, N1936V, Port Townsend, WA, December 4, 1999 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: December 4, 1999, 11:40 local (19:40 UTC) - Place: Port Townsend, WA - Coordinates: 48.030368, -122.839637 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=48.0304&lon=-122.8396&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report June 22, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 48386 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA029 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/48386/pdf - Page: https://openairdocs.org/ntsb/SEA00LA029 ## Probable cause Compensation for wind conditions was inadequate. Gusting wind conditions were a factor. ## 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 - weather condition - gusts - compensation for wind conditions - inadequate, pilot in command - directional control - not maintained, pilot in command - Nose over, landing - roll ## Analysis The pilot reported that he was aware of gusting wind conditions in the area, however, he opted to continue for landing. While on final approach, the pilot kept the airspeed up to compensate for the crosswind. When the airplane touched down, it bounced and became airborne. The pilot applied power to correct for the situation. When the airplane touched down again, it bounced, then settled to the runway. During the landing roll, a gust of wind lifted the right wing and the left wing contacted the runway surface. The airplane veered to the left, crossed the runway and taxiway, and collided with a ditch off the side of the taxiway. The airplane then nosed over and came to rest inverted. The pilot reported that the crosswind was 10 to 15 knots, with gusts in excess of 15 knots. ## Factual narrative On December 4, 1999, at 1140 Pacific standard time, a Cessna 140, N1936V, registered to and operated by the pilot as a 14 CFR Part 91 personal flight, nosed over during the landing roll at the Jefferson County International Airport, Port Townsend, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft was substantially damaged and the commercial pilot, the sole occupant, received minor injuries. The flight departed from Snohomish, Washington, about 30 minutes prior to the accident. During a telephone interview, the pilot reported that he was aware of gusting wind conditions in the area, however, he opted to continue for a landing on runway 9. While on final approach, the pilot kept the airspeed up a little higher to compensate for the crosswind. When the aircraft touched down, it bounced and became airborne. The pilot applied power to correct for the situation. The aircraft touched down a second time and again bounced, then settled to the runway. The pilot reported that during the landing roll, a gust of wind lifted the right wing and the left wing contacted the runway surface. The airplane veered to the left, crossed the runway, a 30 foot wide grass area, and a taxiway before colliding with a ditch on the north side of the taxiway. The airplane then nosed over and came to rest inverted. The pilot reported that the winds were from the east southeast at 10-15 knots, with gusts in excess of 15 knots. ## Aircraft - Registration: [N1936V](https://openairdocs.org/deregistered/N1936V-2013-07-09), registration cancelled 2013-07-09, S/N 14140, built 1948 (OpenAirDocs) - Reported make and model: Cessna 140 - Registry model: [Cessna 140](https://openairdocs.org/model/cessna-140) (registry code 2071602) (OpenAirDocs) - Registry engine: [Continental C85 series](https://openairdocs.org/engine/continental-c85-series) (registry code 17008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 14140 - Airframe hours: 1547 - Engines: Continental C85-12F 85 horsepower reciprocating - Damage: Substantial damage - Fire: On-Ground - Flight: Personal, Part 91 - Registered owner: Elden W.

(-23) Aircraft had no reported mechanical failures. Jefferson county airport had approx. 20 knots crosswinds when pilot elden larson attempted to make a… 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.
