Overfueled Takeoff Leads to Stall and Controlled Descent (N8772N)

Truckee, CA, US

On September 7, 1998, a Piper PA-28-140 (registration N8772N) was involved in an aviation accident near Truckee, CA. Investigators recorded the probable cause as: The pilot's failure to use carburetor heat in temperature conditions conducive to carburetor icing and his failure to lean the engine in a high density altitude environment, which combined, led to a partial loss of engine power and the onset of a stall during… This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot took off with twice the required fuel, leading to inadequate climb performance. The aircraft stalled and was intentionally nosed into the ground to avoid obstacles.

Introduction

An aviation accident occurred when a pilot departed with significantly more fuel than necessary for the planned flight to the next fuel stop. The excess weight affected the aircraft's performance during the initial climb.

Sequence of Events

After takeoff, the aircraft was unable to gain sufficient speed or altitude. The pilot had not leaned the mixture, further degrading performance. As conditions worsened, the pilot decided to turn back toward the departure airport. During the turn, the aircraft began to stall. The pilot then nosed the aircraft into the ground to avoid colliding with power lines and other nearby structures.

Environmental Factors

At the time of the accident, the ambient temperature was 63 degrees Fahrenheit, with a dew point of 61 degrees. The density altitude was reported as 7,400 feet, indicating reduced engine and aerodynamic efficiency due to the high altitude and humidity.

Pilot Report

The pilot stated that he had not attempted to use carburetor heat during the flight. He also reported that there were no mechanical malfunctions with the aircraft prior to the accident.

Frequently asked questions

What happened in the 7 Sept 1998 Piper PA-28-140 accident near Truckee, CA?

A pilot took off with twice the required fuel, leading to inadequate climb performance. The aircraft stalled and was intentionally nosed into the ground to avoid obstacles.

What aircraft was involved and where did it happen?

The accident on 7 Sept 1998 involved a Piper PA-28-140, registration N8772N, at Truckee, CA.

What was the probable cause of the accident?

The pilot's failure to use carburetor heat in temperature conditions conducive to carburetor icing and his failure to lean the engine in a high density altitude environment, which combined, led to a partial loss of engine power and the onset of a stall during the forced landing in rough uneven terrain.
