On January 21, 1989, a Champion 7EC (registration N7596E) was involved in an aviation accident near Luxemburg, MN. Investigators recorded the probable cause as: The pilot's failure to ensure the aircraft was within allowable weight and center of gravity limits prior to takeoff, which resulted in a loss of control and collision with terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
Witnesses observed the aircraft circling at low altitude before descending rapidly into terrain. Investigation confirmed the pilot exceeded weight and balance parameters, leading to a fatal accident.
What happened
Witnesses reported seeing the aircraft circling at a very low altitude prior to it descending rapidly to collide with the terrain.
The investigation
The investigation revealed that the pilot had exceeded weight and balance parameters. Specifically, the aircraft was over the allowable takeoff weight and exceeded the aft center of gravity limits.
Findings
The primary factor contributing to the accident was the exceeding of weight and balance limits, which compromised the aircraft's performance and controllability during the critical phase of flight.
Probable cause
The pilot's failure to ensure the aircraft was within allowable weight and center of gravity limits prior to takeoff, which resulted in a loss of control and collision with terrain.
