Holding short of runway 28L on taxiway C1 I was given clearance to cross to the hangar. This clearance was given after a jet had departed runway 28L. 1/2 way across runway 28L I was informed by ground control that a left or right turn would have to be made from my position. I then stopped the aircraft just beyond the centerline of runway 28L. I then looked to the right to confirm that there was sufficient room to make the turn. I clearly saw that the runway lights were far enough away to make the turn safely. After the turn was made on runway 28L, and just prior to the turn onto taxiway F, I heard a noise out the right side of the aircraft that sounded like splashing water. I then visually inspected the right wing, nacelle, and propeller from the cockpit. Everything appeared normal so I continued to the hangar where after shutdown I inspected the right side. I noticed impact damage to 2 of the blades on the #2 propeller. The damage consisted of a half-dollar sized bump on 1 blade, and an inch long split in the nickel leading edge of the adjacent blade. I then went into the hangar to call our maintenance personnel. Considering the nature of the damage to just 2 blades, I maintain that some type of debris was either deflected off the nosewheel or pulled up from the surface into the propeller.

Title: WHILE TAXIING ACROSS A RWY ENRTE TO PARKING, AN LTT ACR ACFT STRUCK DEBRIS CAUSING DAMAGE TO 2 BLADES OF A 3 BLADED PROP. FOREIGN OBJECT DAMAGE.
Narrative: HOLDING SHORT OF RWY 28L ON TXWY C1 I WAS GIVEN CLRNC TO CROSS TO THE HANGAR. THIS CLRNC WAS GIVEN AFTER A JET HAD DEPARTED RWY 28L. 1/2 WAY ACROSS RWY 28L I WAS INFORMED BY GND CTL THAT A L OR R TURN WOULD HAVE TO BE MADE FROM MY POS. I THEN STOPPED THE ACFT JUST BEYOND THE CTRLINE OF RWY 28L. I THEN LOOKED TO THE R TO CONFIRM THAT THERE WAS SUFFICIENT ROOM TO MAKE THE TURN. I CLRLY SAW THAT THE RWY LIGHTS WERE FAR ENOUGH AWAY TO MAKE THE TURN SAFELY. AFTER THE TURN WAS MADE ON RWY 28L, AND JUST PRIOR TO THE TURN ONTO TXWY F, I HEARD A NOISE OUT THE R SIDE OF THE ACFT THAT SOUNDED LIKE SPLASHING WATER. I THEN VISUALLY INSPECTED THE R WING, NACELLE, AND PROP FROM THE COCKPIT. EVERYTHING APPEARED NORMAL SO I CONTINUED TO THE HANGAR WHERE AFTER SHUTDOWN I INSPECTED THE R SIDE. I NOTICED IMPACT DAMAGE TO 2 OF THE BLADES ON THE #2 PROP. THE DAMAGE CONSISTED OF A HALF-DOLLAR SIZED BUMP ON 1 BLADE, AND AN INCH LONG SPLIT IN THE NICKEL LEADING EDGE OF THE ADJACENT BLADE. I THEN WENT INTO THE HANGAR TO CALL OUR MAINT PERSONNEL. CONSIDERING THE NATURE OF THE DAMAGE TO JUST 2 BLADES, I MAINTAIN THAT SOME TYPE OF DEBRIS WAS EITHER DEFLECTED OFF THE NOSEWHEEL OR PULLED UP FROM THE SURFACE INTO THE PROP.
