Narrative:

Takeoff was attempted in heavy rain. As the aircraft accelerated, it impacted standing water 800 ft down the runway. It then began to skid off the left side, coming to rest at the 1000 ft markers, 25 ft off the left side of the runway. Incidentally, as the water was impacted, power was reduced, but this was not sufficient to stop the aircraft. A takeoff in heavy rain, which caused the standing water, caused the problem. In the future, waiting for the rainfall to decrease in order to assess runway conditions, would be more prudent. There was no damage to the aircraft and I, the pilot, was not injured. This was ruled an incident by the FAA.

Title: A PA34 SINGLE CARGO PLT, DURING HIS TKOF ROLL FROM OFP, ENCOUNTERED STANDING WATER WHICH CAUSED HIM TO ENTER A SKID THAT CAUSED HIM TO COME TO REST TO THE L SIDE OF THE RWY.

Narrative: TKOF WAS ATTEMPTED IN HVY RAIN. AS THE ACFT ACCELERATED, IT IMPACTED STANDING WATER 800 FT DOWN THE RWY. IT THEN BEGAN TO SKID OFF THE L SIDE, COMING TO REST AT THE 1000 FT MARKERS, 25 FT OFF THE L SIDE OF THE RWY. INCIDENTALLY, AS THE WATER WAS IMPACTED, PWR WAS REDUCED, BUT THIS WAS NOT SUFFICIENT TO STOP THE ACFT. A TKOF IN HVY RAIN, WHICH CAUSED THE STANDING WATER, CAUSED THE PROB. IN THE FUTURE, WAITING FOR THE RAINFALL TO DECREASE IN ORDER TO ASSESS RWY CONDITIONS, WOULD BE MORE PRUDENT. THERE WAS NO DAMAGE TO THE ACFT AND I, THE PLT, WAS NOT INJURED. THIS WAS RULED AN INCIDENT BY THE FAA.
