SMA HAS INSUFFICIENT PWR TO STAY AIRBORNE; TKOF ABORTED.

Narrative

THE FLT WAS INITIATED IN THIS SMA WITH THE PLT (MYSELF) AND 1 PAX FROM PIE. WE FLEW WITH FULL FUEL TO SRQ WHERE WE LANDED AND TAXIED TO FBO TO LOAD 500 LBS OF SUPPLIES TO AIRLIFT TO MIAMI FOR THE HURRICANE ANDREW RELIEF. WE HAD A NORMAL TKOF AND FLEW ON AN IFR FLT PLAN TO HOMESTEAD GENERAL WHERE WE LANDED AND OFF-LOADED THE SUPPLIES. WE TAXIED TO RWY 9 (THOUGH THE WIND WAS OUT OF THE S; I WANTED; AS OTHERS HAD DONE; TO AVOID INCOMING FLTS ON RWY 18). WE DID A RUNUP AND ALL SEEMED NORMAL. ON THE TKOF ROLL; WE REACHED ROTATION SPD AND BACK PRESSURE WAS APPLIED ON THE YOKE. THE NOSE CAME UP NORMALLY; BUT WE BEGAN LOSING AIRSPD AND SEEMED TO HAVE INSUFFICIENT PWR TO CONTINUE THE TKOF. THE TKOF WAS ABORTED; BUT WE WERE UNABLE TO STOP BEFORE REACHING THE END OF THE RWY AND BEYOND THAT; A SECURITY FENCE. WE STRUCK THE FENCE CAUSING CONSIDERABLE DAMAGE TO THE ACFT; BUT I HAD MY PAX WERE UNINJURED. THE ACFT WAS MOVED BY A FLATBED TRUCK WITH A FORKLIFT TO THE LARGE HANGAR. BECAUSE OF THE HURRICANE DAMAGE (ANDREW); THERE WERE NO LANDLINES (PHONES) BUT WE CONTACTED THE COUNTY AVIATION AUTHORITY BY AMATEUR RADIO. I INQUIRED ABOUT INFORMING THE FAA; AND THEY REPLIED THAT THIS WAS UNNECESSARY AS NO ONE WAS INJURED. LATER; I SPOKE TO A MAN AT HOMESTEAD GENERAL WITH THE COUNTY AVIATION AUTHORITY AND HE REPEATED THAT THE FAA DID NOT WISH TO BE INFORMED IF NO INJURIES OCCURRED.
