A non-instrument rated pilot attempted an instrument landing system approach at Houston Intercontinental without charts, resulting in a crash past the runway end during a missed approach.

What happened

The pilot, who did not hold an instrument rating, departed Dallas, Texas, intending to fly under visual flight rules to Houston Gulf Port Airport. Upon arrival in the Houston area, deteriorating weather conditions prevented a safe landing at the destination. Consequently, the pilot contacted air traffic control and requested vectors to Houston Intercontinental Airport.

Air traffic control provided navigation vectors for an instrument landing system approach to runway 08. The pilot proceeded with the approach without possessing the necessary published charts or having the proper authorization. During the attempt to execute a missed approach procedure, the aircraft crashed past the end of the runway.

The investigation

The investigation focused on the operational context of the flight and the pilot's qualifications. It was determined that the pilot lacked the instrument rating required to conduct an instrument approach in controlled airspace. The failure to have the appropriate charts contributed to the inability to execute the missed approach correctly.
