On March 7, 1993, a Champion 7EC (registration N9099B) operated by Rogers, David M. was involved in an aviation accident near Riverside, CA. Investigators recorded the probable cause as: The pilot's improper control of the aircraft during landing, resulting in a loss of directional control and subsequent nosing over. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A dual-student pilot receiving a check-out in a conventional gear airplane nosed over the aircraft after over-correcting for a left excursion on touchdown.
What happened
The incident occurred during a training flight involving a certificated airline transport pilot and flight instructor who was acting as a dual student. The individual was receiving a check-out in an airplane equipped with conventional landing gear. Upon touchdown, the aircraft swerved to the left. In response to this excursion, the pilot attempted to correct the heading but over-corrected, causing the aircraft to swing to the right. To regain control, the pilot applied hard braking. The combination of the directional instability and the braking input caused the airplane to nose over onto its back.
The investigation
The source material does not provide specific details regarding mechanical examinations or post-accident findings beyond the immediate sequence of events during the landing roll.
Probable cause
The pilot's improper control of the aircraft during landing, resulting in a loss of directional control and subsequent nosing over.
