Narrative:

I broke out of clouds at 2500 ft with runway in sight. I canceled IFR and entered a right downwind for runway 18. Thunderstorms were in the area with heavy rain. I maintained VFR throughout the downwind, base, and final. On touchdown, the aircraft hydroplaned to the right. The wind was 270 degrees at 3 KTS according to ASOS. I corrected back to centerline, at which time the aircraft started going left. By the time I got it straight, the left main tire was off the side of the runway. As I slowed, the whole aircraft exited the left side of the runway. The left main was off for approximately 1000 ft then the nose for 500 ft then the right main for 100 ft. I also contacted a 2000 ft remaining sign when I stopped. The aircraft engine had to be taken off for overhaul due to mud, grass, and water they ingested. The aircraft sustained minor damage to leading edge heat shield and side of fuselage. Although it was raining at the time, I still had good visibility. Some contributing factors were the tires were worn and the runway had been sealed with liquid asphalt. This coupled with the wet runway probably was not a good idea to land. If the runway was grooved it might have helped. In retrospect, the flight probably should not have happened. I called my employer 3 times to see if he really needed to go and he told me to come on. Next time maybe instead of the phone calls, just spell it out that today is not a good day to fly. As these city owned airport runways start cracking, they don't have the funds to fix them right, so the cheapest is the liquid asphalt sealer. This in itself really makes runways slick, then when you add water they are like ice.

Title: SMT SINGLE PLT EXECUTIVE JET PLT LOST CTL DURING LNDG IN RAIN ON FRESHLY SEALED ASPHALT NON CTLED ARPT RWY RESULTING IN GOING OFF THE L SIDE OF THE RWY. THE ACFT SUSTAINED DAMAGE TO THE ENG NACELLES' LEADING INLETS AND ENGS.

Narrative: I BROKE OUT OF CLOUDS AT 2500 FT WITH RWY IN SIGHT. I CANCELED IFR AND ENTERED A R DOWNWIND FOR RWY 18. TSTMS WERE IN THE AREA WITH HVY RAIN. I MAINTAINED VFR THROUGHOUT THE DOWNWIND, BASE, AND FINAL. ON TOUCHDOWN, THE ACFT HYDROPLANED TO THE R. THE WIND WAS 270 DEGS AT 3 KTS ACCORDING TO ASOS. I CORRECTED BACK TO CTRLINE, AT WHICH TIME THE ACFT STARTED GOING L. BY THE TIME I GOT IT STRAIGHT, THE L MAIN TIRE WAS OFF THE SIDE OF THE RWY. AS I SLOWED, THE WHOLE ACFT EXITED THE L SIDE OF THE RWY. THE L MAIN WAS OFF FOR APPROX 1000 FT THEN THE NOSE FOR 500 FT THEN THE R MAIN FOR 100 FT. I ALSO CONTACTED A 2000 FT REMAINING SIGN WHEN I STOPPED. THE ACFT ENG HAD TO BE TAKEN OFF FOR OVERHAUL DUE TO MUD, GRASS, AND WATER THEY INGESTED. THE ACFT SUSTAINED MINOR DAMAGE TO LEADING EDGE HEAT SHIELD AND SIDE OF FUSELAGE. ALTHOUGH IT WAS RAINING AT THE TIME, I STILL HAD GOOD VISIBILITY. SOME CONTRIBUTING FACTORS WERE THE TIRES WERE WORN AND THE RWY HAD BEEN SEALED WITH LIQUID ASPHALT. THIS COUPLED WITH THE WET RWY PROBABLY WAS NOT A GOOD IDEA TO LAND. IF THE RWY WAS GROOVED IT MIGHT HAVE HELPED. IN RETROSPECT, THE FLT PROBABLY SHOULD NOT HAVE HAPPENED. I CALLED MY EMPLOYER 3 TIMES TO SEE IF HE REALLY NEEDED TO GO AND HE TOLD ME TO COME ON. NEXT TIME MAYBE INSTEAD OF THE PHONE CALLS, JUST SPELL IT OUT THAT TODAY IS NOT A GOOD DAY TO FLY. AS THESE CITY OWNED ARPT RWYS START CRACKING, THEY DON'T HAVE THE FUNDS TO FIX THEM RIGHT, SO THE CHEAPEST IS THE LIQUID ASPHALT SEALER. THIS IN ITSELF REALLY MAKES RWYS SLICK, THEN WHEN YOU ADD WATER THEY ARE LIKE ICE.
