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 ultralights were flying in loose formation on a short x-country. During the flt, the wind shifted to the east and created some turbulence and downdrafts near the end of the journey on final approach. The lead vehicle landed without knowledge that his companion had crashed. Witnesses saw the accident ultralight in apparent trouble descending and ascending before diving into the ground. The surviving plt of the other acft said he encountered a sink over a depression while on final, but needed it to lose alt so it did not bother him and he landed without incident. The vehicle was found intact and all acft parts were accounted for. Investigation did not reveal any evidence of an inflight malfunction or failure.
