NTSB narrative

DURING CRUISE AT FLIGHT LEVEL 350, WHILE OVER THE GULF OF MEXICO, THE CREW RECEIVED A CLIMB RESOLUTION ADVISORY FROM THE TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS). THE CREW INITIATED A CLIMB INITIALLY AT 1,500 FPM, AND THEN INCREASED THE CLIMB TO 2,500 FPM. A PASSENGER STANDING NEAR THE AFT GALLEY SUSTAINED SERIOUS INJURIES. THE TRAFFIC WAS A NASA T-38A PERFORMING A FUNCTIONAL CHECK FLIGHT. DURING THE STALL SERIES, THE T-38A HAD DESCENDED THROUGH FLIGHT LEVEL 350, AND THE PILOT INITIATED A CLIMB BACK TO ABOVE FLIGHT LEVEL 350. THE T-38A WAS VFR BASED ON A LETTER OF AGREEMENT, AND THE PILOT HAD BEEN ADVISED BY ATC NOT TO GO BELOW FLIGHT LEVEL 350 BECAUSE OF NUMEROUS TRAFFIC IN THE AREA. THE LETTER OF AGREEMENT BETWEEN HOUSTON ARTCC, NASA, HOUSTON INTERCONTINENTAL TOWER, AND THE 147TH FIGHTER INTERCEPTOR GROUP, ELLINGTON FIELD, TEXAS, WAS IN VIOLATION OF EXTANT INTERNATIONAL CIVIL AVIATION ORGANIZATION (ICAO) AGREEMENTS, AND WAS RESCINDED ON 3/10/93, THE DAY FOLLOWING THE ACCIDENT.

Probable cause

THE FAILURE OF THE PILOT OF THE T-38A TO FOLLOW FLIGHT ADVISORIES. A FACTOR WHICH CONTRIBUTED TO THE ACCIDENT WAS THE DEVELOPMENT OF A LETTER OF AGREEMENT BETWEEN THE FAA AND NASA WHICH WAS NOT IN ACCORDANCE WITH ICAO PROCEDURES.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
  • API snapshot SHA-256: 5bda801b68ab3ffd4d7daf237c9a561c8c5fd52f366313f08d5ee771eedc4b4e; retrieved 2026-09-18T18:40:23.869Z.
