Narrative:

Local training flight remained in geu's traffic pattern. After completing normal simulated single engine pattern; gear was verified down and locked. After normal touchdown with correct pitch attitude; student decelerated the aircraft to a fast taxi pace to simulate a short runway. Subsequently; student retracted the flaps; visually confirmed them up; returned the right propeller lever to full forward; and advanced the throttles slowly to maximum power. During this time; the nose gear collapsed despite back elevator on my part. I had been satisfied that student had retracted the flaps and was not inadvertently raising the gear. Thus; was primarily at this point concerned with engine performance and aircraft centerline control. To my recollection; student was handling the throttles when the gear collapsed. At no point did I see any attempt to operate the gear selector at that phase of the takeoff and the student confirms that he did not operate the selector. Aircraft damage was the following: both propellers bent; shock loaded engines and minor damage to the underside of the nose section. No injuries. Noted no fuel leaks or smells and shut down aircraft on runway.

Title: NOSE GEAR ON BE76 COLLAPSES DURING TKOF ROLL OF TOUCH-AND-GO FOLLOWING LNDG WITH SIMULATED ENG FAILURE.

Narrative: LOCAL TRAINING FLT REMAINED IN GEU'S TFC PATTERN. AFTER COMPLETING NORMAL SIMULATED SINGLE ENG PATTERN; GEAR WAS VERIFIED DOWN AND LOCKED. AFTER NORMAL TOUCHDOWN WITH CORRECT PITCH ATTITUDE; STUDENT DECELERATED THE ACFT TO A FAST TAXI PACE TO SIMULATE A SHORT RWY. SUBSEQUENTLY; STUDENT RETRACTED THE FLAPS; VISUALLY CONFIRMED THEM UP; RETURNED THE R PROP LEVER TO FULL FORWARD; AND ADVANCED THE THROTTLES SLOWLY TO MAX PWR. DURING THIS TIME; THE NOSE GEAR COLLAPSED DESPITE BACK ELEVATOR ON MY PART. I HAD BEEN SATISFIED THAT STUDENT HAD RETRACTED THE FLAPS AND WAS NOT INADVERTENTLY RAISING THE GEAR. THUS; WAS PRIMARILY AT THIS POINT CONCERNED WITH ENG PERFORMANCE AND ACFT CTRLINE CTL. TO MY RECOLLECTION; STUDENT WAS HANDLING THE THROTTLES WHEN THE GEAR COLLAPSED. AT NO POINT DID I SEE ANY ATTEMPT TO OPERATE THE GEAR SELECTOR AT THAT PHASE OF THE TKOF AND THE STUDENT CONFIRMS THAT HE DID NOT OPERATE THE SELECTOR. ACFT DAMAGE WAS THE FOLLOWING: BOTH PROPS BENT; SHOCK LOADED ENGS AND MINOR DAMAGE TO THE UNDERSIDE OF THE NOSE SECTION. NO INJURIES. NOTED NO FUEL LEAKS OR SMELLS AND SHUT DOWN ACFT ON RWY.
