PLT DEV - PLT PREMATURELY RAISES THE GEAR ON TKOF.

Narrative

WHILE RECEIVING DUAL RECURRENCY TRAINING IN A BEECHCRAFT T-34B; A FELLOW FLT INSTRUCTOR AND MYSELF ELECTED TO COMPLETE SOME LNDG PRACTICE AT FRANKLIN MUNICIPAL ARPT. THE TFC PATTERN FOR RWY 27 WAS ALREADY IN USE BY A MIL HELI. AS SUCH WE ANNOUNCED INTENTIONS AND FELL IN TRAIL ON DOWNWIND FOR LNDG. FIRST LNDG WAS A FULL STOP WITHOUT INCIDENT. THE SECOND TKOF AND LNDG WERE LIKEWISE UNEVENTFUL. WE THEN DECIDED TO COMPLETE A THIRD LNDG AND DEPART FOR HOME BASE (NGU). PATTERN AND LNDG WERE WITHOUT INCIDENT. HOWEVER; AS WE BEGIN THE FINAL TKOF TO DEPART; AS THE ACFT ACCELERATED PAST 55 KTS INDICATED; I FELT THE ACFT SHUDDER AND THEN THE NOSE GEAR GAVE WAY. AS THE ACFT SLID TO A STOP MY FELLOW INSTRUCTOR AND MYSELF UNBUCKLED AND DEPARTED THE ACFT. AFTER WE DETERMINED THERE WAS NO RISK OF FIRE WE RETURNED TO THE ACFT. ON INSPECTION WE FOUND THE LNDG GEAR HANDLE IN THE UP POS. THOUGH I DO NOT RECALL DOING SO I CONCLUDED THAT AFTER LNDG I HAD UNINTENTIONALLY PLACED THE GEAR HANDLE UP AFTER RETRACTING THE FLAPS. I HAVE A SUBSTANTIAL AMOUNT OF EXPERIENCE IN VARIOUS RETRACTABLE ACFT. I CAN ONLY DETERMINE THAT THIS WAS ONLY THE SECOND FLT IN WHICH I HAD PERFORMED LNDG FROM THE REAR COCKPIT IN THIS MAKE AND MODEL AS A FACTOR. ALSO THE FACT THAT THE FLT WAS GOING SO ROUTINELY AND SMOOTHLY; AS TO LULL ME IN TO A MOMENTARY LAPSE OF ATTN POST LNDG. I MAY HAVE DONE THE ONE THING WHICH I HAVE ADMONISHED DOZENS OF STUDENTS NOT TO DO. LET MY HANDS MOVE FASTER THAN MY INTENTIONS.
