On May 21, 1998, a Grumman G-164A (registration N9632) was involved in an aviation accident near Red Lake Falls, MN. Investigators recorded the probable cause as: a locked brake for undetermined reasons. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An airplane landed on an unpaved runway portion, then veered right on the paved section despite corrective action, exited the runway, and nosed over in a plowed field. Inspection found no mechanical cause for the loss of control.
Accident Details
During the landing, the airplane touched down on a section of the runway that was not paved. It subsequently traveled onto the paved portion of the runway as it continued the landing roll. After rolling approximately 50 feet on the paved surface, the airplane abruptly veered to the right and departed the side of the runway, despite the pilot's remedial efforts.
The airplane then continued into an adjacent plowed field, where it nosed over. Skid marks were observed on the runway following the accident, indicating that the wheels had left visible traces on the pavement.
Post-Accident Examination
An inspection of the airplane was conducted to determine the cause of the loss of directional control. However, the examination did not reveal any mechanical or structural deficiencies that could account for the unexpected veering or the subsequent excursion. The reason for the loss of control remains undetermined based on the available evidence.
