Incident Summary
On a dark night, an airplane conducting a visual approach to an airport collided with a 50-foot tall pole. The pole was part of the antenna for a nondirectional radio beacon (NDB). The airport was unlighted at the time of the event.
Airport Status
An FAA aeronautical study for the installation of the NDB determined that the antenna was not a hazard to air navigation and did not require obstruction lighting. On the night of September 29, airport personnel reported that the runway lights and rotating beacon had been turned off to close the airport to night operations. However, no Notice to Airmen (NOTAM) was filed regarding the closure.
Pilot Actions
Prior to initiating the flight, the pilot received a weather briefing during which he specifically requested NOTAMs on the airport. The briefer informed him that none were on file. Witnesses observed the airplane circle the airport two or three times before entering a descent that appeared to be for landing.
Toxicology
Toxicological testing detected doxylamine (known as Unisom) in the pilot's urine. Doxylamine is not approved for use while flying. Additionally, dextromethorphan (an expectorant), pseudoephedrine (a decongestant), and phenylpropanolamine (a decongestant) were detected in the pilot's blood and urine.
