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.

HE ASSUMED A BUG HAD BLOCKED THE PITOT OPENING & CONTINUED TO RIO LINDA. ON ARRIVAL, THE ACFT BOUNCED DRG AN ATTEMPTED 'WHEEL LANDING.' THE PLT BELIEVED THE AIRSPEED MAY HAVE BEEN TOO HIGH (OR TOO LOW), CAUSING THE ACFT TO BOUNCE. HE CONTINUED THE LANDING, BUT THE ACFT BOUNCEDAGAIN, SO HE INITIATED A GO-AROUND.

NTSB Probable Cause
FAILURE OF THE PILOT TO MAINTAIN PROPER RUNWAY ALIGNMENT DURING AN ABORTED LANDING. RELATED FACTORS WERE: A FALSE AIRSPEED INDICATION, THE PILOT'S LACK OF FAMILIARITY WITH THE AIRCRAFT, HIS IMPROPER USE OF CARBURETOR HEAT, HIS DIVERTED ATTENTION, AND THE FENCE.
