On November 18, 2004, at 0751 eastern standard time, a Socata TB-21-TC, N55510, was substantially damaged during collision with trees following a missed approach to Greater Binghamton Airport (BGM), Binghamton, New York. The certificated private pilot was not injured. Instrument meteorological conditions prevailed for the personal flight that originated at Wilkes-Barre/Scranton International Airport (AVP), at 0720. An instrument flight rules flight plan was filed for the flight conducted under 14 CFR Part 91. In a telephone interview, the pilot explained that the purpose of the flight was to pick up two passengers in Binghamton, and transport them on an "Angel Flight" to Boston, Massachusetts. He further explained that at takeoff from Wilkes-Barre, the "predicted" ceiling at the Greater Binghamton Airport was 700 feet overcast. Upon arrival to the Binghamton area, the reported ceilings at BGM were 200 feet overcast, and the pilot continued with the ILS Runway 34 approach. During the approach the airplane was "low and off centerline," the pilot initiated the missed approach procedure, and the airplane struck trees during the climb. The airplane continued to climb, and the pilot returned to Wilkes-Barre and completed a safe landing. The pilot reported that the airplane's handling and performance were "great," and that there were no mechanical deficiencies with the airplane. When asked what led to the collision with trees, he responded, "Pilot error; I'm not blaming anyone but me." At 0753, the weather reported at Greater Binghamton Airport included an overcast ceiling at 200 feet with 3/4 miles of visibility in mist. At 0723, the weather reported at BGM included an overcast ceiling at 200 feet with 1/2 mile visibility in fog. Weather observations for the 3 hours after the accident each showed an overcast ceiling at 200 feet.
