Overview
Witnesses observed a pilot conduct two approaches and landings prior to an accident. On the landing immediately before the accident, witnesses reported an extremely hard landing on the nose gear. The pilot then taxied back to the takeoff position without stopping to examine the aircraft.
Sequence of Events
On the subsequent landing, witnesses stated that just after touchdown, the nose gear "started to shimmy." The aircraft then veered off the runway and encountered a ditch.
Witness Accounts
Witnesses provided detailed observations of the pilot's actions. They noted the hard landing on the nose gear during the preceding landing, and the absence of any inspection by the pilot before taking off again. The shimmying nose gear and subsequent veer-off were directly observed by witnesses.
