NO FLIGHT PLAN HAD BEEN FILED, AND THE PILOT CONTINUED HIS FLIGHT TO PINEDALE, WYOMING. THE PILOT REPORTED THAT DURING THE TAKEOFF, THE AIRPLANE STRUCK AN AIRPORT TAXIWAY SIGN. WHEN HE HAD THE AIRPLANE EXAMINED IN PINEDALE, A MECHANIC DETERMINED THAT THE LEFT AFT STRUT AND THE LEFT AFT WING SPAR NEEDED TO BE REPLACED. THE PILOT DID NOT REPORT THE ACCIDENT UNTIL SEPTEMBER 10, 1999. (-23) NO OFFICIAL NWS WEATHER AVAILABLE FOR THIS AIRPORT. PILOT SAID WEATHER WAS GUSTY.
