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 PILOT WAS MAKING A SECOND TOUCH-AND-GO LANDING ON RUNWAY 35. HE SAID HE LOWERED THE LANDING GEAR AND OBSERVED A GREEN LIGHT (SAFE) INDICATION. THE AIRPLANE LANDED WHEELS-UP ON THE RUNWAY. EXAMINATION OF THE COCKPIT DISCLOSED THE LANDING GEAR SELECTOR WAS IN THE UP POSITION AND THE FLAP CONTROL WAS IN THE DOWN POSITION. THE PILOT SAID THE TOUCHDOWN WAS SMOOTH AND HE RAISED THE FLAPS AND 'BEGAN TO CLEAN UP THE AIRPLANE' FOR TAKEOFF. HIS ATTENTION WAS DIVERTED WHEN HE BEGAN TO LOSE DIRECTIONAL CONTROL AND 'THE AIRCRAFT SEEMED TO BECOME AIRBORNE AGAIN.' ACCORDING TO A BEECH AIRCRAFT CORPORATION SPOKESMAN, THE 95-C55 BARON HAS A SQUAT SWITCH ON THE MAIN LANDING GEAR THAT PREVENTS INADVERTENT GEAR RETRACTION SO LONG AS WEIGHT IS APPLIED TO THE STRUTS. WHEN THE WEIGHT IS REMOVED, THE GEAR WILL RETRACT.
NTSB Probable Cause
THE PILOT'S INADVERTENT RETRACTION OF THE LANDING GEAR. A FACTOR WAS THE PILOT'S LACK OF FAMILIARITY WITH THE AIRPLANE.
