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.

A RAMP GUIDEMAN WAS SERIOUSLY INJURED WHEN A BOEING 757-222 RAN OVER HIS RIGHT LEG WITH THE NOSE GEAR DURING PUSH BACK. TWO GROUND PERSONNEL WERE INVOLVED IN THE OPERATION ON THE RAMP AREA. ONE PERSON WAS THE TRACTOR DRIVER AND THE OTHER PERSON WAS THE GUIDEMAN. THE GUIDEMAN WAS WALKING TO THE RIGHT OF THE AIRPLANE'S FUSELAGE AND AFT OF THE NOSE GEAR. DURING THE PUSH BACK THE GUIDEMAN MOVED TOWARDS THE AIRPLANE'S FUSELAGE. THE GUIDEMAN FAILED TO SEE AND AVOID THE ONCOMING NOSE GEAR TO MAINTAIN PROPER CLEARANCE. THE NOSE GEAR CAUGHT THE GUIDEMAN'S RIGHT HEEL AND RAN OVER HIS RIGHT LEG CRUSHING AND SEVERING IT. THE ACCIDENT OCCURRED ON THE YELLOW TAXI LINE IN THE GATE AREA. THE GUIDEMAN HAD COMPLETED HIS RECURRENT ANNUAL RAMP TRAINING IN FEBRUARY 1992. ACCORDING TO THE AIRLINE, THE GUIDE PERSON SHOULD NOT HAVE POSITIONED HIMSELF ON THE YELLOW LINE DURING PUSH BACK.
