NTSB narrative
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.
Probable cause
THE PILOT'S INADVERTENT RETRACTION OF THE LANDING GEAR. A FACTOR WAS THE PILOT'S LACK OF FAMILIARITY WITH THE AIRPLANE.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
