Crystal City, TX, US

On October 13, 1987, a Cessna 175 (registration N6512E) was involved in an aviation accident near Crystal City, TX. Investigators recorded the probable cause as: The pilot's failure to maintain terrain clearance during a nighttime visual approach to an unlighted private airstrip, due to impairment from methamphetamine, amphetamine, and alcohol. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot attempting a nighttime visual approach to an unlit private airfield struck trees and power lines, resulting in a crash approximately 2.5 miles short of the runway threshold.

What happened

The pilot was operating a flight during nighttime conditions with the intention of conducting a visual approach to a private airstrip that lacked lighting systems. During the final segment of the approach, the aircraft encountered terrain and obstacles before reaching the intended landing area. The collision sequence began when the aircraft struck trees, followed by contact with an overhead power line. After passing under the power line, the aircraft impacted additional trees before ultimately striking the ground.

The accident occurred approximately 2.5 miles short of the runway threshold. Following the crash, blood samples were collected from the pilot roughly 3.5 hours after the event. Toxicological analysis revealed the presence of methamphetamine at a concentration of 423 ng/mL and amphetamine at 28 ng/mL. A blood alcohol level of 0.03% was also detected.

The investigation

Investigators examined the wreckage site and reviewed toxicology reports to determine contributing factors. The physical evidence indicated that the aircraft had flown under a power line before impacting additional trees, confirming the sequence of events described in the narrative. The absence of lighting on the private strip was noted as a significant environmental factor.

Findings

The pilot's ability to navigate and maintain situational awareness during the night approach was likely impaired by substance use. The presence of methamphetamine and amphetamine in the pilot's system, along with alcohol, contributed significantly to the loss of control and navigation errors. The decision to attempt a visual approach to an unlighted facility at night further increased the risk of controlled flight into terrain.

Safety message

Pilots must ensure they are fit for duty and free from impairing substances before operating aircraft. Approaching unlighted airstrips at night requires extreme caution, proper equipment, and adequate visibility. Relying solely on visual cues in low-light conditions without adequate preparation can lead to catastrophic outcomes.

Probable cause

The pilot's failure to maintain terrain clearance during a nighttime visual approach to an unlighted private airstrip, due to impairment from methamphetamine, amphetamine, and alcohol.
