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 HELICOPTER WAS ON A NEW AIRCRAFT ACCEPTANCE FLIGHT TEST WITH TWO PILOTS ON BOARD. THE LEFT SEAT PILOT REPRESENTED THE PURCHASER AND THE RIGHT SEAT PILOT WAS A COMPANY PILOT AND WAS DESIGNATED PILOT IN COMMAND. THEY WERE PRACTICING A TOUCHDOWN AUTOROTATION. DURING TOUCHDOWN, BOTH PILOTS WERE ON THE CONTROLS AND THE HELICOPTER TOUCHED DOWN IN A RIGHT DRIFT AND WITH THE RIGHT SKID LOWER. AT TOUCHDOWN, THE HELICOPTER ROLLED TO THE RIGHT AND CAME TO REST ON ITS SIDE. NO TRANSFER OF CONTROL PROCEDURES HAD BEEN ESTABLISHED BEFORE TAKEOFF. LEFT SEAT PILOT HAD GONE 13 MONTHS WITHOUT PERFORMING TOUCHDOWN AUTOROTATIONS IN THIS TYPE OF HELICOPTER.
NTSB Probable Cause
AN UNSTABLE TOUCHDOWN WHICH RESULTED IN A ROLLOVER, INADEQUATE SUPERVISION BY THE PIC, AND FAILURE OF THE PIC TO TAKE CONTROL OF THE HELICOPTER IN A TIMELY MANNER. A FACTOR RELATED TO THE ACCIDENT WAS THE LEFT SEAT PILOT'S LACK OF RECENT EXPERIENCE IN TOUCHDOWN AUTOROTATIONS.
