Israel Aircraft Industries 1124 N112EM accident near Cincinnati, Ohio

Probable cause

Loss of control due to insufficient airspeed on takeoff and premature landing gear retraction, which resulted in the collapse of the left landing gear as the airplane impacted the runway.

NTSB analysis

The flight instructor and pilot were conducting initial training for a type certification. As the airplane touched down on the first landing, the flight instructor directed a touch-and-go landing. During takeoff, the airplane settled back to the runway and the right wingtip struck the runway, most likely due to insufficient airspeed. The airplane subsequently yawed left, the left main gear collapsed, and the airplane skidded to a stop on the runway.

Examination and testing of the landing gear system revealed no anomalies. No damage occurred to the side or jury brace of the left main landing gear, which would be expected following a mechanical failure. Based on this lack of damage and no anomalies with the landing gear system, it is likely that the landing gear handle had been moved to the "up" position during the takeoff sequence.
