# NTSB FTW00LA162: Air Tractor AT-401B, N5028Q, Thibodaux, LA, June 1, 2000 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: June 1, 2000, 08:20 local (13:20 UTC) - Place: Thibodaux, LA - Coordinates: 29.789297, -90.81932 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=29.7893&lon=-90.8193&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report December 4, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 49327 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW00LA162 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49327/pdf - Page: https://openairdocs.org/ntsb/FTW00LA162 ## Probable cause The pilot's failure to maintain clearance with the power lines while maneuvering during an aerial application flight. A factor was the sunglare on the windscreen. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, maneuvering - aerial application - object - wire,transmission - clearance - not maintained, pilot in command (cause) - light condition - sunglare (contributing factor) ## Analysis The pilot flew the agricultural airplane around the target area (crawfish pond) to be sprayed, 'looking for obstacles and wind direction.' The pilot made the first spray run from the north to the south, and the second pass from the south to north. After completing the second run, the pilot passed over power lines and executed a turn to the right and into the direction of the sun. According to the pilot, the sunlight and glare on the windscreen 'blocked my vision' temporarily. While still in the turn, the pilot regained 'forward vision' and realized the airplane was flying 'into the power lines.' After striking the power lines, the airplane came to rest upright in the crawfish pond. ## Factual narrative On June 1, 2000, at 0820 central daylight time, an Air Tractor AT-401B agricultural airplane, N5028Q, struck a power line during an aerial application flight near Thibodaux, Louisiana. The airplane was owned and operated by Golden Ranch Aviation, Inc., of Schriever, Louisiana, under 14 Code of Federal Regulations Part 137. The commercial pilot, sole occupant, received serious injuries, and the airplane sustained substantial damage. Visual meteorological conditions prevailed for the local flight, and a flight plan was not filed. The flight originated approximately 0800 from the Golden Ranch Aviation, Inc., private airstrip. According to the pilot's statement, the pilot circled the target area (a crawfish pond, located approximately 10-12 miles northwest of the airstrip) to be sprayed, "looking for obstacles and wind direction." The pilot made the first spray run from the north to the south, and the second pass from the south to north. After completing the second run, the pilot passed over power lines and executed a turn to the right and into the direction of the sun. According to the pilot, the sunlight and glare on the windscreen "blocked [his] vision" temporarily. While still in the turn, the pilot regained "forward vision" and realized the airplane was flying "into the power lines." After striking the power lines, the airplane came to rest upright in the crawfish pond. According to the U.S. Naval Observatory Astronomical Applications Department, the official sunrise on June 1, 2000, occurred at 0603. According to the FAA inspector, who examined the wreckage, the wings sustained spar damage, and the propeller was damaged. ## Aircraft - Registration: [N5028Q](https://openairdocs.org/aircraft/N5028Q), registered now, S/N 401B-1028, built 1997 (OpenAirDocs) - Reported make and model: Air Tractor AT-401B - Registry model: [Air Tractor AT-401B](https://openairdocs.org/model/air-tractor-at-401b) (registry code 0390207) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 401B-1028 - Airframe hours: 535 - Engines: P&W R1340-AN 600 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Golden Ranch Aviation, Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, December 21, 1999, 5 hours before - Departed: NONE, SCHRIEVER, LA ## Flight crew As NTSB recorded them.

(-23) During aerial application maneuvers, aircraft struck power lines. Pilot reported losing sight of power lines due to sun glare on windshield. 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.
