Narrative:

While taking off at slc airport with student in left seat, we went through the proper checklists and all instrument runup checks were satisfactory. We were cleared for takeoff. Reached VMC plus 5 (85), rotated, climbed to 150 ft (AGL) when the right engine began to lose power then kick back in again. I double- checked the fuel pumps which were on, then thought my student was doing something. Next I went through a denial phase, telling myself this cannot be happening, looked over at the airspeed indicator that was dropping below VMC. Corrective action was to lower the nose to regain airspeed, keep directional control and proceed with mixture preparation, throttle, gear and flaps identify, verify. However, my main concern was landing the airplane safely, which I did. I then told my student to get on the brakes. He was in a daze and it took several times of repeating this before any brakes were applied. We hit a cow during the rollout through the north field, slc airport property area, hit the airport boundary fence, and nosed over into a ditch. I opted not to put gear up because I was familiar with the shape (conditions of the field ahead). We may have came to a stop before the fence if brakes were applied sooner. There might have been quicker judgement, however. At night as given the situation, I acted the best as I could. I received 11 stitches to my head, my student walked away with no injury. The flight was a ferry flight to provo, ut.

Title: SAM TWIN SUFFERS ACFT DAMAGE DURING ABORTED TKOF AFTER BEING AIRBORNE AND PIC EXECUTING LNDG PROC OVERSHOT ROLLOUT. RWY EXCURSION.

Narrative: WHILE TAKING OFF AT SLC ARPT WITH STUDENT IN L SEAT, WE WENT THROUGH THE PROPER CHKLISTS AND ALL INST RUNUP CHKS WERE SATISFACTORY. WE WERE CLRED FOR TKOF. REACHED VMC PLUS 5 (85), ROTATED, CLBED TO 150 FT (AGL) WHEN THE R ENG BEGAN TO LOSE PWR THEN KICK BACK IN AGAIN. I DOUBLE- CHKED THE FUEL PUMPS WHICH WERE ON, THEN THOUGHT MY STUDENT WAS DOING SOMETHING. NEXT I WENT THROUGH A DENIAL PHASE, TELLING MYSELF THIS CANNOT BE HAPPENING, LOOKED OVER AT THE AIRSPD INDICATOR THAT WAS DROPPING BELOW VMC. CORRECTIVE ACTION WAS TO LOWER THE NOSE TO REGAIN AIRSPD, KEEP DIRECTIONAL CTL AND PROCEED WITH MIXTURE PREPARATION, THROTTLE, GEAR AND FLAPS IDENT, VERIFY. HOWEVER, MY MAIN CONCERN WAS LNDG THE AIRPLANE SAFELY, WHICH I DID. I THEN TOLD MY STUDENT TO GET ON THE BRAKES. HE WAS IN A DAZE AND IT TOOK SEVERAL TIMES OF REPEATING THIS BEFORE ANY BRAKES WERE APPLIED. WE HIT A COW DURING THE ROLLOUT THROUGH THE N FIELD, SLC ARPT PROPERTY AREA, HIT THE ARPT BOUNDARY FENCE, AND NOSED OVER INTO A DITCH. I OPTED NOT TO PUT GEAR UP BECAUSE I WAS FAMILIAR WITH THE SHAPE (CONDITIONS OF THE FIELD AHEAD). WE MAY HAVE CAME TO A STOP BEFORE THE FENCE IF BRAKES WERE APPLIED SOONER. THERE MIGHT HAVE BEEN QUICKER JUDGEMENT, HOWEVER. AT NIGHT AS GIVEN THE SIT, I ACTED THE BEST AS I COULD. I RECEIVED 11 STITCHES TO MY HEAD, MY STUDENT WALKED AWAY WITH NO INJURY. THE FLT WAS A FERRY FLT TO PROVO, UT.
