Narrative:
ATP student under instruction was attempting a touch-and- go after being instructed the day before by me not to do touch-and-goes in a twin. On rotation the manifold pressure on the left engine was seen to rise and the RPM's dropped. The left propeller was seen to slow down and was immediately pulled to feather. The student was instructed to retract the gear and a climb out was initiated. The tower was informed of the situation and no assistance was required. We returned to the airport and landed. On parking, a large amount of oil was seen under the engine. The aircraft had had a new starter fitted the day before. The a&P had forgotten to replace 2 nuts, and a plug close to the magnetos had come loose in flight. This had allowed a cog to drop off inside the engine, cutting off the magnetos and allowing the oil to drain from the engine. Although we did not feel that there was any emergency situation, for us (as pilots) we were in control at all times of the aircraft. We knew that the recommended procedure for a loss of engine is to declare an emergency.

Title: A C310 DURING A TRAINING FLT ON ROTATION FOR A TOUCH-AND- GO LNDG HAD THE L ENG FAIL CAUSED BY AN IMPROPERLY INSTALLED ENG STARTER.
Narrative: ATP STUDENT UNDER INSTRUCTION WAS ATTEMPTING A TOUCH-AND- GO AFTER BEING INSTRUCTED THE DAY BEFORE BY ME NOT TO DO TOUCH-AND-GOES IN A TWIN. ON ROTATION THE MANIFOLD PRESSURE ON THE L ENG WAS SEEN TO RISE AND THE RPM'S DROPPED. THE L PROP WAS SEEN TO SLOW DOWN AND WAS IMMEDIATELY PULLED TO FEATHER. THE STUDENT WAS INSTRUCTED TO RETRACT THE GEAR AND A CLBOUT WAS INITIATED. THE TWR WAS INFORMED OF THE SIT AND NO ASSISTANCE WAS REQUIRED. WE RETURNED TO THE ARPT AND LANDED. ON PARKING, A LARGE AMOUNT OF OIL WAS SEEN UNDER THE ENG. THE ACFT HAD HAD A NEW STARTER FITTED THE DAY BEFORE. THE A&P HAD FORGOTTEN TO REPLACE 2 NUTS, AND A PLUG CLOSE TO THE MAGNETOS HAD COME LOOSE IN FLT. THIS HAD ALLOWED A COG TO DROP OFF INSIDE THE ENG, CUTTING OFF THE MAGNETOS AND ALLOWING THE OIL TO DRAIN FROM THE ENG. ALTHOUGH WE DID NOT FEEL THAT THERE WAS ANY EMER SIT, FOR US (AS PLTS) WE WERE IN CTL AT ALL TIMES OF THE ACFT. WE KNEW THAT THE RECOMMENDED PROC FOR A LOSS OF ENG IS TO DECLARE AN EMER.
