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.

ACCORDING TO THE CAPTAIN, THE COPLT WAS MAKING THE LANDING & CROSSED THE THRESHOLD AT 50 TO 60 FT AGL AT 110 TO 115 KTS. HE SAID A SLIGHTLY HIGHER AIRSPEED WAS USED TO COMPENSATE FOR A SMALL ABOUNT OF ICE THAT REMAINED ON THE LEADING EDGE OF THE WINGS. IN THE FLARE, THE ACFT YAWED LEFT & REPORTEDLY TOUCHED DOWN WITH THE NOSE ABOUT 15 DEGS TO THE LEFT. THE LEFT MAIN WHEEL TOUCHED DOWN ABOUT 21 FT FROM THE EDGE OF THE 150 FT WIDE RWY. THE CAPT TOOK CONTROL & APPLIED CORRECTIVE ACTION, BUT THE ACFT WENT OFF THE RWY, HIT A SNOW BANK & MUD, THEN THE NOSE GEAR COLLAPSED.THE NORMAL APCH SPEED WAS 103 KTS FOR THE ACFT'S WEIGHT.
