Narrative:
On the evening of aug/wed/97, I was flying a corporate aircraft for hire. During 1 of my 4 flying legs I had hit something with the left propeller during taxi. The WX conditions at toronto and cleveland were thunderstorm and heavy rainshowers. The visibility was poor due to the heavy rainshowers. I had completed the trip returning to evansville, in. Upon landing and postflt inspection I discovered that the left propeller tips had received some damage. I reported the damage to maintenance and was told the propeller had substantial damage so I grounded the aircraft. 1 of 2 things may have occurred. First, during taxi while using the beta propeller mode I may have picked up some debris on a taxiway or ramp that could have been pulled into the propeller. Second, I may have hit a runway or taxi light while taxiing the aircraft. However, if I hit a runway or taxi light the aircraft would have to had gone off the pavement and I feel that I would have definitely known this.

Title: PLT OF AN SMT TWIN TURBOPROP OBSERVED PROP BLADE TIP DAMAGE TO THE L PROP. HE DID NOT KNOW HOW IT HAPPENED, IF A FOREIGN OBJECT WAS SUCKED INTO THE PROP, OR AN ARPT RWY TXWY LIGHT WAS STRUCK?
Narrative: ON THE EVENING OF AUG/WED/97, I WAS FLYING A CORPORATE ACFT FOR HIRE. DURING 1 OF MY 4 FLYING LEGS I HAD HIT SOMETHING WITH THE L PROP DURING TAXI. THE WX CONDITIONS AT TORONTO AND CLEVELAND WERE TSTM AND HVY RAINSHOWERS. THE VISIBILITY WAS POOR DUE TO THE HVY RAINSHOWERS. I HAD COMPLETED THE TRIP RETURNING TO EVANSVILLE, IN. UPON LNDG AND POSTFLT INSPECTION I DISCOVERED THAT THE L PROP TIPS HAD RECEIVED SOME DAMAGE. I RPTED THE DAMAGE TO MAINT AND WAS TOLD THE PROP HAD SUBSTANTIAL DAMAGE SO I GNDED THE ACFT. 1 OF 2 THINGS MAY HAVE OCCURRED. FIRST, DURING TAXI WHILE USING THE BETA PROP MODE I MAY HAVE PICKED UP SOME DEBRIS ON A TXWY OR RAMP THAT COULD HAVE BEEN PULLED INTO THE PROP. SECOND, I MAY HAVE HIT A RWY OR TAXI LIGHT WHILE TAXIING THE ACFT. HOWEVER, IF I HIT A RWY OR TAXI LIGHT THE ACFT WOULD HAVE TO HAD GONE OFF THE PAVEMENT AND I FEEL THAT I WOULD HAVE DEFINITELY KNOWN THIS.
