Probable cause

The pilot's improper flare technique which resulted in a hard landing. A factor in the accident was the sudden appearance of a high wind condition.

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 reported that when the flight began, the local surface wind was not over 3 mph. However, as the flight progressed, he noted that the wind speed was increasing and he elected to terminate the flight. The pilot said that when he touched down the surface wind had increased to between 8 and 12 mph. The baloon landed hard, bounced 30 to 40 feet up in the air, and then landed hard again.
