PRIVATE PLT PRACTICING SOFT FIELD TKOF HAS ENG PROBLEM DURING INITIAL CLB. TURNS BACK AND LANDS.

Narrative

I RENTED AN SMA FROM THE FBO DISPATCH. I WAS PLANNING TO DO TOUCH-AND-GO TKOFS AND LNDGS IN ACCORDANCE WITH THE FBO COMMERCIAL/INST PART 141 SYLLABUS. AFTER PREFLT; THE ENG STARTED IMMEDIATELY. OAK GND CLRED ME TO TAXI TO THE E RUNUP AREA WHERE I PERFORMED MY ENG RUNUP. USING THE CHKLIST; I INCREASED THE RPM TO 1700 RPM. THE R MAGNETO SHOWED 100-150 RPM DROP. THE L SHOWED 150 RPM DROP AND WAS RUNNING A BIT ROUGH. I PUT THE IGNITION SWITCH BACK TO BOTH. I INCREASED THE RPM TO FULL PWR (2300 RPM) AND LEANED THE MIXTURE OUT. I RECHKED THE MAGNETOS (L AND R) AND FOUND THEM TO BE QUITE SMOOTH. ALL OTHER GAUGES WERE 'IN THE GREEN.' PWR WAS THEN REDUCED TO 1700 RPM. BOTH MAGNETOS WERE AGAIN CHKED. EACH SHOWED A 100-150 RPM DROP AND NO ROUGHNESS. ALMOST IMMEDIATELY; OAK TWR (118.3) CLRED ME FOR TKOF ON 27L. I HAD DECIDED TO PERFORM A SOFT FIELD TKOF. I ADDED 10 DEGS OF FLAPS; TAXIED ONTO THE ACTIVE 27L; APPLIED FULL PWR; AND HELD THE NOSEWHEEL OFF OF THE GND UNTIL AIRBORNE. ONCE AIRBORNE; I REMAINED IN GND EFFECT UNTIL REACHING 75 KTS. I THEN PROCEEDED TO CLB OUT. AT 100 FT; I RETRACTED THE FLAPS. SOMEWHERE BTWN 250 FT AND 300 FT; THE ENG COUGHED AND DIED. THE TACHOMETER SHOWED 1000-1150 RPM. IT WAS VERY QUIET; AS IF THE ENG WERE AT IDLE. I WAS JUST A LITTLE PAST RWY 33 TO MY BEST RECOLLECTION OF THE EVENT. I SAID 'OAK TWR; SMA HAS HAD AN ENG FAILURE; REQUEST LNDG ON RWY 33.þ THEY TOOK ABOUT 5-10 SECONDS TO ANSWER. I TRIMMED THE AIRPLANE FOR 60 KTS AS I DRIFTED OFF OF THE END OF 27L. WHEN THEY GOT BACK TO ME; THEY CLRED ME FOR 33 OR RWY OF MY CHOICE. I PULLED THE THROTTLE BACK TO IDLE AND MADE A 180 DEG TURN. I TOLD THEM I WOULD LAND ON 9L. I WAS ABLE TO USE THE THROTTLE AS I MADE THE APCH BECAUSE I FELT I WAS TOO LOW. AFTER TOUCHDOWN; I TAXIED BACK TO FBO AND RPTED THE INCIDENT TO THE CHIEF FLT INSTRUCTOR. I THEN HAD THE PROBLEM WRITTEN UP AT THE DISPATCH WHEN I RETURNED THE KEYS.
