Narrative:

During a stop, during a cross country trip, the airplane received minor damage to the wingtip area during taxi. The aircraft was flown back to the originating airport without having a certified mechanic verify the airworthiness or issue a ferry certificate if needed. After taxiing approximately 50 ft from the ramp to the taxiway leading to the runway, the left wingtip struck a 2-3 inch metal conduit running up the corner of a hangar/flight school, which is adjacent to the ramp and taxiway. I realized I was cutting the corner too close to the building at the last second and applied the brakes just as the wingtip struck the corner of the building. Mental distrs played a role in causing the damage due to worrying about fuel and not being able to update my flight plan (leaving with an inaccurate flight plan previously filed and with fuel tanks just over half full). I immediately shut down the plane and inspected the damage. At the position where I started to make the corner was far too short of the yellow guideline on the taxiway. The damage to the left wingtip consisted of an approximately 3 inch wide by 3/4 inch deep vertical dent on the sheet metal of the leading edge just adjacent to the wingtip and a 1 inch horizontal crack at the leading edge of the plastic wingtip cover. No fasteners were in the immediate vicinity of the damage.

Title: C152 STUDENT PLT HIT A 2-3 INCH METAL CONDUIT WITH THE ACFT WING. THE STUDENT PLT THEN FLEW ON TO HIS DEST.

Narrative: DURING A STOP, DURING A XCOUNTRY TRIP, THE AIRPLANE RECEIVED MINOR DAMAGE TO THE WINGTIP AREA DURING TAXI. THE ACFT WAS FLOWN BACK TO THE ORIGINATING ARPT WITHOUT HAVING A CERTIFIED MECH VERIFY THE AIRWORTHINESS OR ISSUE A FERRY CERTIFICATE IF NEEDED. AFTER TAXIING APPROX 50 FT FROM THE RAMP TO THE TXWY LEADING TO THE RWY, THE L WINGTIP STRUCK A 2-3 INCH METAL CONDUIT RUNNING UP THE CORNER OF A HANGAR/FLT SCHOOL, WHICH IS ADJACENT TO THE RAMP AND TXWY. I REALIZED I WAS CUTTING THE CORNER TOO CLOSE TO THE BUILDING AT THE LAST SECOND AND APPLIED THE BRAKES JUST AS THE WINGTIP STRUCK THE CORNER OF THE BUILDING. MENTAL DISTRS PLAYED A ROLE IN CAUSING THE DAMAGE DUE TO WORRYING ABOUT FUEL AND NOT BEING ABLE TO UPDATE MY FLT PLAN (LEAVING WITH AN INACCURATE FLT PLAN PREVIOUSLY FILED AND WITH FUEL TANKS JUST OVER HALF FULL). I IMMEDIATELY SHUT DOWN THE PLANE AND INSPECTED THE DAMAGE. AT THE POS WHERE I STARTED TO MAKE THE CORNER WAS FAR TOO SHORT OF THE YELLOW GUIDELINE ON THE TXWY. THE DAMAGE TO THE L WINGTIP CONSISTED OF AN APPROX 3 INCH WIDE BY 3/4 INCH DEEP VERT DENT ON THE SHEET METAL OF THE LEADING EDGE JUST ADJACENT TO THE WINGTIP AND A 1 INCH HORIZ CRACK AT THE LEADING EDGE OF THE PLASTIC WINGTIP COVER. NO FASTENERS WERE IN THE IMMEDIATE VICINITY OF THE DAMAGE.
