Pilots who witnessed the accident told NTSB investigators that they saw the aircraft wobbling out of control as it was on its final approach.
Local weather reports indicate 10 mile visibility and light winds at the time of the accident.
One of the aircraft’s wings detached during the crash. This led to a fire that destroyed one house and badly damaged two others.
