Miramar Marine Corps Air Sta Airport
Aircraft Accident/Incident Report

San Diego, California 92145
Friday, October 15, 2004 10:15 PDT

NTSB Narrative Summary Released at Completion of Accident

The airplane impacted terrain while the pilot was performing low-level aerobatic maneuvers at an airshow. Review of videotaped footage of the pilot's performance showed that about 15 minutes into the flight, the pilot began a rolling maneuver that the airplane was to pull out of and continue parallel to the ground. The airplane never pulled out of the downward flight path and impacted terrain. This particular airshow was a milestone for the pilot and there may have been self-induced pressure to perform well.

NTSB Probable Cause Narrative

the pilot's failure to maintain adequate clearance from terrain while performing low-level aerobatic maneuvers.
