1995-07-09: Piper PA-38-112 (N2529A) — Rubidoux, CA

Rubidoux, CA, US

On July 9, 1995, a Piper PA-38-112 (registration N2529A) was involved in an aviation accident near Rubidoux, CA. Investigators recorded the probable cause as: The pilot's failure to properly calculate the aircraft's weight and balance prior to flight, which resulted in the aircraft being loaded beyond its maximum gross weight limit and unable to climb. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Following takeoff, the aircraft was unable to gain altitude and collided with utility lines approximately 1.5 miles from the runway end due to gross weight issues.

What happened

Shortly after initiating takeoff, the aircraft failed to achieve a climb gradient sufficient to clear obstacles, remaining below 50 feet above ground level. The flight path intersected with overhead utility lines located approximately 1.5 miles from the departure end of the runway, resulting in a collision.

The investigation

Subsequent inquiries by Federal Aviation Administration inspectors revealed significant discrepancies regarding the aircraft's loading conditions. Investigators determined that the pilot had not performed a weight and balance calculation prior to flight. Furthermore, the pilot admitted to law enforcement deputies that he was unaware of the aircraft's empty weight, leading to an inability to verify if the loaded aircraft exceeded its maximum gross weight limits.

Findings

The primary factor contributing to the accident was the aircraft's gross weight, which prevented adequate climb performance. The pilot's failure to compute the weight and balance, combined with a lack of knowledge regarding the empty weight, directly resulted in an overloaded condition that compromised the aircraft's ability to climb above 50 feet AGL after takeoff.

Probable cause

The pilot's failure to properly calculate the aircraft's weight and balance prior to flight, which resulted in the aircraft being loaded beyond its maximum gross weight limit and unable to climb.
