Aircraft involved
Probable cause & findings
THE PILOT'S IMPROPER COMPENSATION FOR WIND CONDITIONS AND INADEQUATE AIRSPEED WHICH RESULTED IN AN INADVERTENT STALL AFTER LIFT-OFF. THE WIND CONDITIONS AND THE PILOT'S LACK OF FAMILIARITY WITH THE ACFT WERE CONTRIBUTING FACTORS.
Factual narrative
THE PURPOSE OF THE FLT WAS TO CHECK THE AVIONICS IN THE ACFT. THE START, TAXI & RUN-UP WERE NORMAL. THE PLT RPRTD THAT AS HE WAS TAKING OFF WITH A LEFT X-WIND, THE ACFT ENCOUNTERED A GUST OR SHEAR AT ABOUT 40' AGL. AT THAT TIME, THE STALL WARNING WAS ACTIVATED & THE PLT WAS UNABLE TO MAINTAIN CONTROL OF THE ACFT. SUBSEQUENTLY, IT CONTACTED THE GROUND ON THE LEFT SIDE OF THE RWY & CAME TO REST WITH DAMAGE TO BOTH WING TIPS, THE PROP & THE NOSE & RIGHT MAIN LANDING GEAR. THE PLT NOTED THAT THERE WAS A ROW OF TREES ALONG THE LEFT SIDE OF THE RWY. HE HAD BEEN DENIED A MED CERT ON 1/18/89. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
