Narrative:
USA Jet Flight 199 departed Detroit-Willow Run Airport, MI (YIP) on July 5 for Hamilton (YHM), Canada to pick up cargo. Automotive parts were loaded on board and the flight continued to Shreveport (SHV) where it arrived at 23:19 CDT. After clearing customs it took off again at 23:48 CDT, bound for Saltillo (SLW), Mexico.
The DC-9 crashed in an industrial area 800 m north of the airport. The airplane broke up and burned.

PROBABLE CAUSE
The Aviation Accident and Incident Investigation Directorate determines that the probable causes of the accident were the continuation of an unstable final approach without having the runway in sight and the consequent loss of control - at low altitude - in view of the imminent impact.
CONTRIBUTING FACTORS
- Weather conditions at the airport
- Unstabilized approach
- Fatigue
- Lack of experience of the co-pilot
- Failure to follow proper procedures
- Lack of operational procedures
- Not following proper Saltillo tower controller procedures
- Lack of supervision by the authority
- The coincidence of factors that individually would not represent a substantial increase in the risk of the operations, but that in this case were added, that is; late night flight, little experience of the co-pilot, omission of briefing by the captain, a single Jepessen for two pilots, DME #2 inoperative, captain command bars inoperative, DME arc, ILS/DME approach, omission of fog bank report and finally saturation in the communications with the Monterrey Control Center.
