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 ACCIDENT OCCURRED DURING TAKEOFF FROM A 5000 FT LONG ASPHALT RUNWAY WITH CALM WIND AND 8800 FT DENSITY ALTITUDE. THE PILOT ATTEMPTED TWO TAKEOFFS BUT ABORTED BOTH WHEN THE AIRCRAFT DID NOT REACH TAKEOFF SPEED. THE PILOT SAID THAT PRIOR TO THE FIRST ATTEMPT 'DURING RUNUP DETONATION OCCURRED SO I ENRICHED THE MIXTURE. THEN I APPLIED POWER FOR TAKEOFF - FULL POWER - MIXTURE CONTROL OUT ABOUT 2 INCHES.' THE AIRCRAFT DID NOT ACCELERATE PROPERLY SO SHE ABORTED. DURING THE SECOND TAKEOFF THE PILOT SAID SHE DID NOT ADVANCE THE THROTTLE ALL THE WAY. DESCRIBING THE THIRD ATTEMPT, THE PILOT SAID 'SPEED ON TAKE OFF ROLL IMPROVED - GOT UP TO 65 IAS - END OF RUNWAY CAME. PULLED OFF, STALL WARNING HORN, DROPPED NOSE - NO ADDED POWER - HIT THE GROUND & ROLLED THROUGH GRASS...' ACCORDING TO THE TAKEOFF CHART FOR THIS AIRCRAFT, THE TAKEOFF DISTANCE SHOULD HAVE BEEN ABOUT 2000 FEET.
