AeroMéxico

Following an uneventful flight from Mexico City, the crew started the descent to Reynosa-General Lucio Blanco Airport and encountered poor weather conditions with heavy rain falls issued from the tropical storm 'Keith'. Following a wrong approach configuration, the aircraft was too high on the glide and approaching at an excessive speed. It landed too far down the wet runway 31 and was unable to stop within the remaining distance. It overran, lost its undercarriage, struck several houses, went down an embankment and came to rest in a canal. All 90 occupants were rescued, among them one passenger was slightly injured. On the ground, four people were killed.

The base of the empennage struck the runway surface upon landing at Mexico City-Benito Juárez Airport. The aircraft was stopped on the runway and all 72 occupants evacuated safely. The aircraft was written off.

AeroMéxico flight AM498 was a scheduled passenger flight from Mexico City to Los Angeles with intermediate stops at Guadalajara, Loreto and Tijuana. The DC-9, named 'Hermosillo', departed Tijuana Airport at 11:20 and proceeded toward Los Angeles at FL100. At 11:44 Coast Approach Control cleared the flight to 7,000 feet. Just three minutes earlier Piper PA-28-181 Cherokee N4891F departed Torrance Airport, CA for a VFR flight to Big Bear, CA. On board were a pilot and two passengers. The Piper pilot turned to an easterly heading toward the Paradise VORTAC and entered the Terminal Control Area (TCA) without receiving clearance from ATC as required by FAR Part 91.90. At 11:47 the AeroMéxico pilot contacted LA Approach Control and reported level at 7,000 feet. The approach controller cleared flight 498 to depart Seal Beach on a heading of 320 degrees for the ILS runway "two five left final approach course...". At 11:51:04, the approach controller asked the flight to reduce its airspeed to 190 KIAS and cleared it to descend to 6,000 feet. At about 11:52:09, flight 498 and the Piper collided over Cerritos at an altitude of about 6,560 feet. The Piper struck the left hand side of the DC-9's horizontal and vertical stabilizer. The horizontal stabilizer sliced through the Piper's cabin following which it separated from the tailplane. Both planes tumbled down out of control. The wreckage and post impact fires destroyed five houses and damaged seven others. Fifteen persons on the ground were killed. The sky was clear, the reported visibility was 14 miles.

Thirty-five minutes after takeoff from Acapulco-General Juan N. Álvarez Airport, while cruising at an altitude of 31,000 feet, the aircraft suffered a cabin decompression. The crew declared an emergency and was cleared to reduce his altitude and to return to Acapulco for an emergency landing. Few minutes later, at an altitude of 6,000 feet, the airplane struck the slope of a mountain and crashed in the Sierra of Guerro, about 65 km east of Zihuatanejo. The aircraft disintegrated on impact and all 18 occupants were killed.

On approach to Chihuahua-General Roberto Fierro Villalobos Airport, the crew encountered bad weather conditions with heavy rain falls, thunderstorms and strong winds. On short final, just prior to flare, the airplane was caught by downdrafts and struck the runway surface. It bounced then veered off runway to the right. The airplane rolled for few dozen meters then came to rest in flames, broken in two. 34 occupants were injured while 32 others were killed, among them two crew members. At the time of the accident, there was thunderstorms in the approach path with heavy rain falls and wind gusting to 54 knots.
