# NTSB LAX05CA005: Bellanca 7GCBC, N50338, Winslow, AZ, October 12, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: October 12, 2004, 13:00 local (20:00 UTC) - Place: Winslow, AZ - Coordinates: 35.025554, -110.726387 - Nearby events: https://openairdocs.org/map.md?lat=35.0256&lon=-110.7264&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report December 28, 2004 - Report: Approved by Office Director - NTSB case key (mKey): 60342 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX05CA005 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60342/pdf - Page: https://openairdocs.org/ntsb/LAX05CA005 ## Probable cause the pilot's failure to maintain directional control during the landing rollout that resulted in a ground loop. ## 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 - directional control - not maintained, pilot in command (cause) - ground loop/swerve - encountered, pilot in command - On ground/water encounter with terrain/water, landing - roll - terrain condition - ground ## Analysis The airplane ground looped during the landing rollout. On final approach at the destination airport the pilot encountered turbulence that rolled the airplane 30 degrees to the right. He made the appropriate correction, and landed normally. The left wing lifted up again on the landing roll and he corrected with left aileron input. The left wing dropped hard, and the airplane rotated counterclockwise and ground looped. The pilot stated that there were no mechanical problems with the airplane or engine. The pilot reported the winds as out of the north at 7 knots. ## Factual narrative On October 12, 2004, at 1300 mountain standard time, a Bellanca 7GCBC, N50338, ground looped after landing at Winslow-Lindbergh Regional Airport (INW), Winslow, Arizona. The pilot/owner operated the airplane under the provisions of 14 CFR Part 91. The airplane sustained substantial damage. The commercial pilot and one passenger were not injured. Visual meteorological conditions prevailed for the cross-country flight that departed La Cholla Airpark (57AZ), Tucson, Arizona, at 1115. No flight plan had been filed. In the pilot's written statement (Pilot/Operator Aircraft Accident Report NTSB Form 6120.1/2), he said there were no problems encountered with the flight. During the final approach, about a half-mile from touchdown, he encountered a strong 30-degree roll to the right. He attributed the roll to turbulence, and corrected for it. The pilot stated that the landing was a "normal" 3-point touchdown. During the landing rollout the left wing lifted up, and he corrected with left aileron input. The pilot reported that the "left wing dropped hard," and the airplane rotated counterclockwise about 270 degrees and ground looped. The right main landing gear sheared off, the right wing tip was wrinkled, and the tail was damaged. The pilot stated that there were no mechanical problems encountered with the airplane or engine. The pilot reported the winds as out of the north at 7 knots. ## Aircraft - Registration: [N50338](https://openairdocs.org/aircraft/N50338), registered now, S/N 1072-79, built 1978 (OpenAirDocs) - Reported make and model: Bellanca 7GCBC - Registry model: [Bellanca 7GCBC](https://openairdocs.org/model/bellanca-7gcbc) (registry code 1220601) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1072-79 - Engines: Lycoming O-320-A2D reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Winston and Mary Walker Family Revocable Trust - Airworthiness certificate: Standard, Normal - Departed: 57AZ, Tucson, AZ - Destination: INW, Winslow, AZ - Airport: INW, Winslow Lindbergh Regional, runway 04, 7,499 × 150 ft, asphalt ## Flight crew As NTSB recorded them.

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.
