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.

WPR10CA478
The pilot stated that he was returning to his home airport when the accident occurred. On final approach, the pilot noted another helicopter was at the parking area, so he altered his course towards taxiway "A" and finished his approach coming to a hover about 3 to 5 feet above the ground. He then commenced to hover-taxi to his parking spot. The student pilot stated that in order to reach his intended parking spot he would have to pass behind an Embraer jet that was holding short of the runway. The pilot reported that he was not expecting the jet blast produced by the turbine engines, and as the helicopter passed behind the airplane, it yawed to the left and rolled onto its side, impacting the ground. According to witnesses, the accident helicopter passed about 30 feet behind the jet at an altitude of about 3 feet above the ground.
NTSB Probable Cause
The student pilot's decision to hover-taxi behind a jet, resulting in the helicopter encountering jet wash and rolling over.
