Narrative:

On rotation during our 5TH touch-and-go, the nose dropped abruptly and both propellers struck the runway. Reacting to the nose drop, I pulled up harder and now found myself airborne with 2 damaged propellers/engine vibration and gear in transit, approximately 30-40 ft AGL, with approximately 3500 ft runway remaining. I closed the throttles, put the gear handle down and aborted the takeoff. The gear did not fully extend prior to touchdown and the aircraft slid to a stop -- no injuries, no fire, no major airframe damage. Originally, I thought the nose gear had collapsed due to a mechanical defect, but on analysis, it appears that the explanation (more likely, this is...) is that rather than putting the gear handle up after rotation, I may have unintentionally moved the gear handle to the up position after advancing the mixtures, propellers, throttles full forward then raising the flaps. If I had continued the sequence and mistakenly raised the gear handle prior to rotation, the nose gear would have started to retract at rotation. The facts on analysis led me to believe I may have raised the gear handle prematurely by mistake.

Title: A C414 PLT RAISED THE GEAR PREMATURELY DURING A TOUCH-AND-GO. AN ABORTED TKOF FOLLOWED WITH THE GEAR COLLAPSING.

Narrative: ON ROTATION DURING OUR 5TH TOUCH-AND-GO, THE NOSE DROPPED ABRUPTLY AND BOTH PROPS STRUCK THE RWY. REACTING TO THE NOSE DROP, I PULLED UP HARDER AND NOW FOUND MYSELF AIRBORNE WITH 2 DAMAGED PROPS/ENG VIBRATION AND GEAR IN TRANSIT, APPROX 30-40 FT AGL, WITH APPROX 3500 FT RWY REMAINING. I CLOSED THE THROTTLES, PUT THE GEAR HANDLE DOWN AND ABORTED THE TKOF. THE GEAR DID NOT FULLY EXTEND PRIOR TO TOUCHDOWN AND THE ACFT SLID TO A STOP -- NO INJURIES, NO FIRE, NO MAJOR AIRFRAME DAMAGE. ORIGINALLY, I THOUGHT THE NOSE GEAR HAD COLLAPSED DUE TO A MECHANICAL DEFECT, BUT ON ANALYSIS, IT APPEARS THAT THE EXPLANATION (MORE LIKELY, THIS IS...) IS THAT RATHER THAN PUTTING THE GEAR HANDLE UP AFTER ROTATION, I MAY HAVE UNINTENTIONALLY MOVED THE GEAR HANDLE TO THE UP POS AFTER ADVANCING THE MIXTURES, PROPS, THROTTLES FULL FORWARD THEN RAISING THE FLAPS. IF I HAD CONTINUED THE SEQUENCE AND MISTAKENLY RAISED THE GEAR HANDLE PRIOR TO ROTATION, THE NOSE GEAR WOULD HAVE STARTED TO RETRACT AT ROTATION. THE FACTS ON ANALYSIS LED ME TO BELIEVE I MAY HAVE RAISED THE GEAR HANDLE PREMATURELY BY MISTAKE.
