Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE ASSISTANCE OF A GROUND LINEMAN WAS OBTAINED TO CONNECT AN EXTERNAL POWER UNIT. AFTER THE ENGINES WERE STARTED, THE LINEMAN DISCONNECTED THE POWER UNIT. THE PILOT NOTED THE DISCONNECT AND COMPLETED THE CHECKLIST. WHEN HE LOOKED UP TO FIND THE LINEMAN, HE SAW AN INDIVIDUAL WALKING AWAY FROM HIS AIRPLANE AND ASSUMED THAT IT WAS THE LINEMAN THAT HAD BEEN ASSISTING HIM. THE PILOT RELEASED THE BRAKES AND STARTED FORWARD MOVEMENT OF THE AIRPLANE. THE LINEMAN, HOWEVER, WAS STILL NEXT TO THE AIRPLANE AT THE EXTERNAL POWER RECEPTACLE, WHICH WAS LOCATED ON THE RIGHT SIDE OF THE NOSE IN FRONT OF THE PROPELLER. THE LINEMAN AND POWER UNIT WERE STRUCK BY THE RIGHT PROPELLER. A TOXICOLOGY CHECK OF THE LINEMAN'S BLOOD SHOWED IT HAD AN ALCOHOL LEVEL OF 0.037%.
NTSB Probable Cause
INADEQUATE COORDINATION BETWEEN THE PILOT AND THE GROUND LINEMAN. A FACTOR RELATED TO THE ACCIDENT WAS: IMPAIRMENT OF THE GROUND LINEMAN FROM CONSUMPTION OF ALCOHOL.
