Overweight Aircraft Descends into Ground During Initial Climb (N1326U)

Linden, MI, US

On December 9, 1989, a Cessna 172M (registration N1326U) operated by 107TH Flying Club Inc was involved in an aviation accident near Linden, MI. Investigators recorded the probable cause as: The pilot's failure to ensure the aircraft was within its allowable gross weight limits, which resulted in a loss of control during initial climb. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft pitched over and descended into the ground during initial climb. Post-accident analysis revealed the plane was significantly overweight.

What happened

The accident airplane departed from the airport and entered its initial climb phase. Shortly after becoming airborne, the aircraft was observed to pitch over and descend directly into the ground. There were no witnesses to the specific mechanical state of the controls during the event, but the flight path indicated a loss of control or inability to maintain altitude.

The investigation

Investigators examined the wreckage for any signs of pre-impact mechanical failure. A thorough search revealed no mechanical defects in either the powerplant or the airframe. This finding suggests that the aircraft's systems functioned as designed up until the point of impact, shifting the focus to operational factors.

Findings

A critical factor identified during the investigation was the weight of the aircraft at the time of the accident. A post-accident computation determined that the aircraft weight was 2527 pounds. This figure is 227 pounds over the allowable gross weight limit of 2300 pounds. The excessive weight likely contributed to the inability to maintain a safe climb gradient or control the aircraft's attitude during the critical initial phase of flight.

Probable cause

The pilot's failure to ensure the aircraft was within its allowable gross weight limits, which resulted in a loss of control during initial climb.
