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.

WITNESSES REPORTED A NORMAL TAKEOFF AND CLIMB WAS MADE TO AN ALT OF APRX 400 FT AGL AT WHICH TIME ENG PWR CEASED/ DECREASED. THE RT WING THEN DROPPED, THE NOSE AND LT WING ROSE AND THE ACFT ENTERED A NEAR VERTICAL DESCENT TO GROUND IMPACT. POST ACCIDENT EXAM OF THE ENGS AND TURBOCHARGERS FAILED TO DISCLOSE ANY PRE-IMPACT FAILURES. EXAM OF THE PROP GOVENORS DISCLOSED AN RPM SETTING BELOW TAKEOFF OR CLIMB PWR; HOWEVER, EXACT RPM SETTING COULD NOT BE DETERMINED. THE PLT HAD RECENTLY PURCHASED THIS ACFT AND MOST OF HIS MULTI-ENGINE EXPERIENCE WAS IN BEECH BARONS. THE THROTTLE QUADRANT LOCATION OF THE THROTTLE AND PROP CONTROLS ON THE BARON ARE IN THE REVERSE POSITION OF THOSE ON THE C-421. THE PLT ALSO HAD NOT BEEN CHECK OUT IN THE C-421.
