Probable cause
the pilot's improper inflight planning/decision and failure to follow the prelanding checklist, resulting in the landing gear not being lowered in sufficient time to be verified down and locked, which resulted in a wheels up landing and substantial damage to the airplane.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that he had been flying for about 20 minutes and became concerned that fog may be moving into the airport area so he returned for a landing. During landing the pilot said he did not extend the landing gear on the downwind leg as he normally did, and he realized he had not done so late, just prior to landing. He said the landing gear touched the runway before it was fully extended and locked. According to the pilot the landing gear collapsed, and the aircraft slid on its belly to a stop on the runway, incurring substantial damage. The pilot said that no mechanical malfunctions existed with either the aircraft, or its systems prior to the accident.
Factual narrative
On December 16, 2000, about 1450 eastern standard time, an Aero Vodochody L39C, N139CG, registered to Glastonbury Aviation LLC, and operated as a Title 14 CFR Part 91 personal flight, had its landing gear collapse during landing at Hilton Head Airport, Hilton Head, South Carolina. Visual meteorological conditions prevailed, and no flight plan was filed. The aircraft incurred substantial damage, and the commercial-rated pilot, the sole occupant of the aircraft was not injured. The flight originated the same day, about 1420.
