Pilot with High Blood Alcohol Level Stalls Aircraft During Approach (N1448F)

Kissimmee, FL, US

On July 11, 1986, a Cessna 172H (registration N1448F) operated by Harvey C. Chapman was involved in an aviation accident near Kissimmee, FL. Investigators recorded the probable cause as: The pilot's decision to fly despite being advised by a mechanic not to do so due to incomplete annual inspection and apparent alcohol consumption, which led to a stall during approach. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot ignored mechanic warnings about incomplete inspections and alcohol consumption, resulting in a stall during landing approach and a crash outside the airport boundary.

What happened

The pilot reported initiating a flight to fly around the traffic pattern. However, the aircraft stalled while on the final approach to land. The aircraft subsequently crashed outside the airport boundary, coming to rest just short of the runway.

Prior to the flight, a mechanic who had been working on the aircraft explicitly informed the pilot that the annual inspection had not been completed and instructed him not to fly the plane. The mechanic also noted that the pilot appeared to have been drinking alcohol. Subsequent testing of the pilot's blood revealed an alcohol level of 0.25%.

The investigation

Investigators examined the circumstances surrounding the flight and the condition of the aircraft prior to departure. The analysis focused on the mechanical status reported by the mechanic and the physiological state of the pilot.

Findings

The primary factors contributing to this accident were fuel exhaustion due to the stall during approach and the pilot's impaired judgment. The pilot ignored specific warnings from a qualified mechanic regarding the airworthiness of the aircraft and his own sobriety. The blood alcohol concentration of 0.25% indicates severe impairment, which directly contributed to the loss of control.

Safety message

Pilots must adhere to strict pre-flight inspections and heed the advice of maintenance personnel. Flying an aircraft with known mechanical deficiencies or under the influence of alcohol is prohibited and extremely dangerous.

Probable cause

The pilot's decision to fly despite being advised by a mechanic not to do so due to incomplete annual inspection and apparent alcohol consumption, which led to a stall during approach.
