Probable cause

Pilot displayed poor inflight planning and preparation for the flight. The pilot did not adequately compensate for the wind conditions resulting in an intentional gear up landing.

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

While on downwind for landing, the airplane encountered a severe downdraft. The pilot opted to abort the landing and retracted the landing gear. With full power applied the airplane continued to descend. The pilot decided to turn back to the airport due to rising terrain and insufficient clearance. The pilot landed the airplane with the landing gear retracted.
