1991-08-17: Luscombe 8A (N2253K) — Christopher J. Hill — Parker, CO

Parker, CO, US

On August 17, 1991, a Luscombe 8A (registration N2253K) operated by Christopher J. Hill was involved in an aviation accident near Parker, CO. Investigators recorded the probable cause as: The pilot's sudden physical impairment due to lightheadedness, which resulted in loss of control during a precautionary landing attempt. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During low-altitude cruise, the pilot became lightheaded and attempted a precautionary landing on a road, striking a fence during flare.

What happened

The flight was proceeding under visual flight rules at an altitude between 500 and 600 feet above ground level. During this phase of cruise flight, the pilot experienced sudden lightheadedness, resulting in physical impairment. Unable to continue normal operations, the pilot initiated a precautionary landing on an adjacent road.

As the aircraft approached the surface for touchdown, it entered the flare phase of the approach. During this maneuver, the left wing or fuselage struck a fence located near the intended landing area. The impact caused immediate loss of aircraft control. The airframe sustained substantial damage as a result of the collision with the fence and the subsequent uncontrolled descent.

The investigation

Post-accident examination confirmed the substantial damage to the airframe. Investigators attempted to determine the etiology of the pilot's physical condition. However, medical evidence was insufficient to establish the specific reason for the pilot's impairment at the time of the event.

Findings

The primary factor in this accident was the pilot's sudden physical incapacitation due to lightheadedness. This unexpected medical event prevented the pilot from maintaining normal flight parameters and executing a controlled landing. The subsequent strike with the fence was a direct consequence of the loss of control following the initial impact.

physical impairment

The inability to diagnose the cause of the pilot's condition highlights the unpredictable nature of in-flight medical emergencies. Pilots operating at low altitudes are particularly vulnerable when sudden incapacitation occurs, as reaction time and altitude for recovery are severely limited.

Probable cause

The pilot's sudden physical impairment due to lightheadedness, which resulted in loss of control during a precautionary landing attempt.
