2 GA PLTS TEMPORARILY LOSE CTL OF THEIR ACFT DURING AN ATTEMPT AT A SOFT FIELD TKOF FROM T40; OK.

Narrative

UPON LNDG AT THE ARPT; I NOTICED A DIRT ROAD XING THE RWY. THE RWY IS AN UNIMPROVED GRASS STRIP. THE ORIENTATION IS N/S WITH A STRUCTURE AND TREES 75 FT FROM THE S END AND A 200-300 FT HILL ON THE NORTHERN END. EITHER SIDE IS LINED WITH 50+ FT TREES. THE NORTHERN 1/2 OF THE RWY SLOPES DOWN FROM THE HILL AT THE END AND THEN BACK UP TO THE ROAD. UPON LNDG; I EXTENDED THE ROLLOUT TO THE S END. WHEN I CONTACTED THE ROAD; IT WAS DURING ROLLOUT. THE IMPACT WAS ENOUGH TO GET THE ACFT AIRBORNE AGAIN. THE ROAD APPARENTLY RISES FROM THE SURFACE OF THE RWY 6-8 INCHES. I WAS WITH ANOTHER PLT. WE DETERMINED ON TKOF; THAT WE NEEDED TO BE AIRBORNE BEFORE THE ROAD. TKOF WAS TO THE N; WIND WAS CALM; SUN WAS SETTING. THE NBOUND ROLL WAS DOWNHILL. THE LIGHTS ON THE RWY WERE STAGGERED AND THERE WAS NO DEFINITIVE WAY TO DETERMINE RWY CTRLINE. THE RWY WAS ONLY 50 FT WIDE. WE STARTED THE ROLL USING SOFT FIELD TKOF TECHNIQUE. THE PLT ON THE R SIDE OF THE ACFT WAS FLYING. WHEN WE GOT TO THE ROAD WE HIT IT; FIRST THE R MAIN; THEN THE L. WE WERE BARELY AT STALL SPD KEEPING THE NOSE OFF THE GND AND HAD THE STALL HORN GOING OFF. THE IMPACT WITH THE ROAD CAUSED US TO BECOME AIRBORNE. THE ANGLE OF THE IMPACT PUT US INTO A L BANK MOMENTARILY. THE PF BECAME DISORIENTATED. THE STRUCTURAL SUPPORT; COMPASS AND GPS ANTENNAE BLOCKED A PORTION OF THE COPLT'S VIEW ON THE L. THUS; HE DID NOT NOTICE HIS PROX TO THE TREES OR RWY ORIENTATION. I CALLED OUT THE PROX TO THE TREES AND THEN ASSUMED CTL OF THE ACFT. I HAD TO PUT THE ACFT INTO A 30 DEG BANK TO AVOID THE TREES. SINCE ACFT WAS AT STALL SPD; I ALSO SETTLED THE PLANE BACK TOWARD THE RWY; ACCELERATED AND THEN CLBED OUT. IN MY OPINION; THIS ARPT IS VERY HAZARDOUS.
