On May 29, 2009, approximately 1130 central daylight time,
N31773, an experimental Gentry Chinook Plus 2 ultralight, sustained
substantial damage when it collided with trees in a nose down
attitude while preparing to land at the Sears private airstrip near
Bridgeport, Texas. The certified flight instructor and the private
pilot were seriously injured. Visual meteorological conditions
prevailed and no flight plan was filed for the instructional flight
conducted under 14 Code of Federal Regulations Part 91.
A Federal Aviation Administration (FAA) inspector performed an
on-scene examination of the airplane and talked with the private
pilot's wife. According to the inspector, the wife stated that this
was her husband's first flight in this airplane. She stated that
after her husband and the instructor departed, they made two
circuits around the private airstrip and were on the third circuit
when she observed the airplane's left wing dip downwards while on
the downwind leg of the traffic pattern. The airplane then spiraled
downwards into the trees. She did not recall hearing any engine
noise at the time of the accident.
Weather at Bridgeport Municipal Airport (XBP), Bridgeport,
Texas, about six miles northwest of the accident site, at 1025, was
reported as winds from 130 degrees at 3 knots, visibility 10 miles,
