1972-01-18: Learjet 25 (N658TC) — Tandy Corporation — Victoria, United States of America

9 fatalitiesVictoria, United States of AmericaLanding (descent or approach)

A fatal accident occurred during a non-precision approach to Victoria County-Foster Airport when an aircraft struck a pole short of the runway.

What happened

While performing a non-precision approach into Victoria County-Foster Airport, the flight crew encountered visibility conditions characterized by fog and marginal weather. As the aircraft was on short final for runway 12L, it collided with a utility pole situated approximately 1.7 miles before the runway threshold. The impact caused the aircraft type to crash into an adjacent field, where the subsequent fire and structural damage from the collision resulted in the total destruction of the plane.

There were nine fatalities among the occupants of the aircraft during this event.

Findings

Investigations into the accident identified several contributing elements related to the flight's operation under instrument flight rules. The crew was operating in weather conditions that fell below established minimums, specifically dealing with a low ceiling and fog. A significant factor was the improper IFR operation by the crew, which included a lack of altitude awareness during the descent into areas of poor visibility.

Additionally, the pilot-in-command misjudged the aircraft's altitude. The investigation also noted that the combination of sunlight and fog created an illusory effect, further complicating the crew's ability to maintain situational awareness regarding their height above the ground.

Probable cause

The accident was caused by improper instrument flight rules operation, specifically involving a failure to maintain proper altitude awareness during descent in low-visibility conditions.
