What happened
During a nighttime approach to Houston-Intercontinental Airport, a twin engine airplane descended too low while attempting to land. The aircraft struck a line of trees before crashing. Of the five people on board, five fatalities were recorded, and one passenger sustained serious injuries.
Findings
The investigation into the accident identified several environmental and operational factors that contributed to the crash. The flight was conducting an ILS approach in conditions characterized by fog and visibility of two miles or less. During this phase of flight, the aircraft was positioned approximately five miles behind a Boeing 727.
Several critical elements led to the undershoot on final approach:
- The pilot utilized an incorrect altimeter setting that was 0.5 below the proper value.
- The presence of wind shear during the approach.
- Encountering high obstructions in the flight path.
Ultimately, the improper IFR operation led to the aircraft striking trees during its descent.
