On May 12, 1994, a Schweizer G-164B (registration N8214S) operated by Sutter Butte Dusters, Inc. was involved in an aviation accident near Yuba City, CA. Investigators recorded the probable cause as: The pilot's decision to overload the aircraft with herbicide, which exceeded the maximum hopper capacity and led to a stall shortly after takeoff. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.
An agricultural aircraft stalled shortly after takeoff from an airstrip while carrying herbicide significantly exceeding the manufacturer's maximum hopper capacity limits.
What happened
The aircraft experienced a stall and subsequently settled onto the ground immediately following its departure from an agricultural airstrip. The pilot reported that the ambient temperature was approximately 87 degrees Fahrenheit at the time of the incident. He indicated that the engine appeared to be operating normally prior to the stall.
The investigation
Review of official Federal Aviation Administration documentation revealed a critical discrepancy regarding the aircraft's payload. The maximum hopper capacity for this specific aircraft model is listed as 2000 pounds. However, the pilot stated that he had loaded 2800 pounds of herbicide aboard the aircraft prior to flight.
Findings
The excessive weight on board contributed significantly to the accident. Carrying 800 pounds over the maximum limit compromised the aircraft's performance capabilities during the critical takeoff phase.
Probable cause
The pilot's decision to overload the aircraft with herbicide, which exceeded the maximum hopper capacity and led to a stall shortly after takeoff.
