Narrative:

The aircraft had conducted 3 previous touch and go maneuvers. This was to be the last before proceeding to lexington for a revenue trip. The aircraft had just landed within 1000' of the approach end of the runway and had initiated a touch and go procedure (i.e., flaps up, trim reset, and power lever advanced to takeoff power). Airspeed was never below 90 KTS. After the power was set, I noticed torque meter fluctuations in the right engine with appropriate yaw. (Airspeed was about 100 KTS, bug speeds for 11,000 pounds were used.) an abort of the takeoff was initiated by myself with maximum braking and reverse thrust. There was insufficient runway remaining to stop. The aircraft left the runway at a speed of about 20 KTS and the aircraft proceeded about 75 yds off the departure end of runway 6. It was necessary to turn to the left to avoid a 3-FOOT dropoff caused by a rainwashed gulley. After the engines were shut down, the aircraft was inspected for damage and the authorities notified. Visible damage was not apparent except for flat spots on the 4 main tires, taxi light filament broken, and a dent in the air intake of the left engine. The aircraft was towed back onto the taxiway. Once on the taxiway, the left engine was started and the aircraft taxied to the ramp. The aircraft underwent a hard landing inspection and a full power check at the capital city airport, which was conducted by nashville air carrier mechanics. Damage incurred was limited to brake assemblies on the main gear and flat spots on the right main tires. Static power check revealed no apparent problems, although an occasional torque fluctuation of 3-4% was noted by the mechanics on the right engine that was deemed to be not significant by the mechanic. The aircraft was ferried back to nashville with the landing gear down under the company's maintenance ferry permit. The flight was normal except for an occasional 5% torque fluctuation in the right engine. The torque gauge was replaced and the landing gear underwent a dye penetrant inspection and a check for normal operation.

Title: ACFT OVERSHOT RWY WHILE ATTEMPTING ABORT FROM TOUCH AND GO LNDG TRAINING.

Narrative: THE ACFT HAD CONDUCTED 3 PREVIOUS TOUCH AND GO MANEUVERS. THIS WAS TO BE THE LAST BEFORE PROCEEDING TO LEXINGTON FOR A REVENUE TRIP. THE ACFT HAD JUST LANDED WITHIN 1000' OF THE APCH END OF THE RWY AND HAD INITIATED A TOUCH AND GO PROC (I.E., FLAPS UP, TRIM RESET, AND POWER LEVER ADVANCED TO TKOF POWER). AIRSPEED WAS NEVER BELOW 90 KTS. AFTER THE POWER WAS SET, I NOTICED TORQUE METER FLUCTUATIONS IN THE RIGHT ENGINE WITH APPROPRIATE YAW. (AIRSPEED WAS ABOUT 100 KTS, BUG SPEEDS FOR 11,000 LBS WERE USED.) AN ABORT OF THE TKOF WAS INITIATED BY MYSELF WITH MAX BRAKING AND REVERSE THRUST. THERE WAS INSUFFICIENT RWY REMAINING TO STOP. THE ACFT LEFT THE RWY AT A SPEED OF ABOUT 20 KTS AND THE ACFT PROCEEDED ABOUT 75 YDS OFF THE DEP END OF RWY 6. IT WAS NECESSARY TO TURN TO THE LEFT TO AVOID A 3-FOOT DROPOFF CAUSED BY A RAINWASHED GULLEY. AFTER THE ENGINES WERE SHUT DOWN, THE ACFT WAS INSPECTED FOR DAMAGE AND THE AUTHORITIES NOTIFIED. VISIBLE DAMAGE WAS NOT APPARENT EXCEPT FOR FLAT SPOTS ON THE 4 MAIN TIRES, TAXI LIGHT FILAMENT BROKEN, AND A DENT IN THE AIR INTAKE OF THE LEFT ENGINE. THE ACFT WAS TOWED BACK ONTO THE TXWY. ONCE ON THE TXWY, THE LEFT ENGINE WAS STARTED AND THE ACFT TAXIED TO THE RAMP. THE ACFT UNDERWENT A HARD LNDG INSPECTION AND A FULL POWER CHECK AT THE CAPITAL CITY ARPT, WHICH WAS CONDUCTED BY NASHVILLE ACR MECHANICS. DAMAGE INCURRED WAS LIMITED TO BRAKE ASSEMBLIES ON THE MAIN GEAR AND FLAT SPOTS ON THE RIGHT MAIN TIRES. STATIC POWER CHECK REVEALED NO APPARENT PROBLEMS, ALTHOUGH AN OCCASIONAL TORQUE FLUCTUATION OF 3-4% WAS NOTED BY THE MECHANICS ON THE RIGHT ENGINE THAT WAS DEEMED TO BE NOT SIGNIFICANT BY THE MECHANIC. THE ACFT WAS FERRIED BACK TO NASHVILLE WITH THE LNDG GEAR DOWN UNDER THE COMPANY'S MAINT FERRY PERMIT. THE FLT WAS NORMAL EXCEPT FOR AN OCCASIONAL 5% TORQUE FLUCTUATION IN THE RIGHT ENGINE. THE TORQUE GAUGE WAS REPLACED AND THE LNDG GEAR UNDERWENT A DYE PENETRANT INSPECTION AND A CHECK FOR NORMAL OPERATION.
