What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot was taxiing the aircraft to parking following a cargo trip. Upon reaching a point where the taxiway makes a right turn, the pilot saw another aircraft being run-up. Markings and a lack of signage indicated that the taxiway also continued straight ahead; however, it was not a continuation of the taxiway but a service road. Continuing straight ahead, the aircraft struck an unused utility pole with the left wingtip. Damage to the aircraft was minor, and there were no injuries or damage to airport property. The Washington ado was notified of the "signage" issue.
