Douglas DC-9

The aircraft departed Hamilton, Ontario, on a cargo flight to Saltillo, Coahuila, with an intermediate stop in Shreveport, LA, carrying two pilots and a load consisting of 4 tons of auto parts. The aircraft arrived in Shreveport at 2319LT and departed at 2348LT. On approach to Saltillo-Plan de Guadalupe Airport, the crew encountered low visibility due to poor weather conditions and dark night. On final approach to runway 17, as the captain was unable to establish a visual contact with the runway, he decided to abandon the approach and initiated a go-around procedure. Nine seconds later, the aircraft stuck the ground and crashed 550 metres to the east of the runway 17 threshold, bursting into flames. The aircraft was totally destroyed, the captain was killed and the copilot was seriously injured.

During the takeoff roll from runway 18 at Goma Airport, the crew started the rotation but the aircraft failed to respond. The aircraft continued, overran and crashed in the Birere District, about 100 metres past the runway end, bursting into flames. Three passengers were killed as well as 37 people on the ground. All other occupants were injured. The aircraft was totally destroyed by impact forces and a post crash fire.

The aircraft was on a post maintenance delivery mission. A crew of two engineers was positioning the aircraft from a technical hangar at Caracas-Maiquetía-Simón Bolívar Airport to the main terminal. While taxiing on the ramp, the crew lost control of the aircraft that rolled to a grassy area and eventually collided with a drainage ditch. The left main gear collapse and the left wing was severely damaged. Both crew were uninjured while the aircraft was damaged beyond repair.

The aircraft with call sign OSL 1 145 which departed Abuja at 1225 hrs UTC (1.25 pm local time) with endurance of 2 hours 40 minutes was on a scheduled passenger flight enroute Port Harcourt with 110 Persons on Board (103 Passengers and 7 Crew) and the flight continued normally. At 1241 hours UTC, the aircraft cruising at FL240 (24,000ft) Above Sea Level (ASL) got in contact with Port Harcourt Approach Control. The Approach control gave the OSL 1145 in - bound clearance to expect no delay on ILS Approach to runway 21, QNH of 1008 and temperature of 33° C. At about 1242 hours UTC (1.42pm local), the Approach controller passed the 1230 hours UTC weather report to the aircraft as follows: Wind - 260° /02kts Visibility - 12km Weather - Nil Cloud - BKN 420m, few CB (N-SE) at 690m QNH - 1008HPA Temperature - 33° C. About 1250 hours UTC (1.50 pm local), the aircraft, which was 90 nautical miles to the station, contacted Approach Control for initial descent clearance and was cleared down to FL 160. The aircraft continued its descent until about 1300 hours UTC (2.00 pm local) when the crew asked Approach Control whether it was raining over the station to which the controller reported negative rain but scattered CB and the crew acknowledged. At 1304 hours UTC, the crew reported established on the glide and the localizer at 8 nautical miles to touch down. Then the Approach controller informed the aircraft of precipitation approaching the station from the direction of runway 21 and passed the aircraft to Tower for landing instructions. At 1305 hours UTC, the aircraft contacted Tower and reported established on glide and localizer at 6 nautical miles to touch down. The controller then cleared the airplane to land on runway 21 but to exercise caution as the runway surface was slightly wet and the pilot acknowledged. At about 1308 hours UTC, the aircraft made impact with the grass strip between runway 21 and taxiway i.e. 70m to the left of the runway edge, and 540m from the runway 21 threshold. At about 60m from the first impact, the aircraft tail section impacted heavily with a concrete drainage culvert. The airplane then disintegrated and caught fire along its path spanning over 790m. The cockpit section and the forward fuselage were found at about 330m from the rest of the wreckage further down on the taxiway creating a total wreckage trail of 1 120m. Fire and rescue operations were carried out after which 7 survivors and 103 bodies were recovered. Five of the survivors died later in the hospital. The accident occurred in `Instrument Meteorological Conditions' (IMC) during the day.

The DC-9 was taxiing to the gate area when it collided with a company A319 that was being pushed back from the gate. Prior to arriving at the destination airport, the DC-9 experienced a loss of hydraulic fluid from a fractured rudder shutoff valve located in the DC-9's right side hydraulic system. The left side hydraulic system had normal hydraulic pressure and quantity throughout the flight. The flightcrew elected to continue to the scheduled destination and declared an emergency while on approach to the destination airport. After landing, the emergency was negated by the flight crew and the airplane taxied to the gate. Flight data recorder information indicates the left engine, which provides power for the left hydraulic system, was shut down during taxi. The captain stated he did not remember shutting the left engine down, and that if he had, it would have been after clearing all runways. The first officer stated that he was unaware that the left engine was shut down. Upon arrival at the gate with the left engine shut down and no hydraulic pressure from the left system and a failure of the right hydraulic system, the airplane experienced a loss of steering and a loss of brakes. The flightcrew requested company maintenance to chock the airplane since they were unable to use brakes to stop the airplane. The crew said they were going to keep the "...engines running in case we have to use reversers..." The airplane began to roll forward and the captain applied reverse thrust but the reversers did not deploy. The airplane impacted the A319 with a speed of approximately 15.65 miles per hour to 16.34 miles per hour. Evacuation of the DC-9 was completed approximately 5:22 minutes after the collision and evacuation of the A319 occurred approximately 13:08 minutes after the collision. Examination of the left hydraulic system revealed no anomalies and examination of the right hydraulic system revealed a fractured rudder shutoff valve that displayed features consistent with fatigue. Following the accident, the airplane manufacturer issued a service letter pertaining to the replacement of the rudder shutoff valve based upon reliability information that was reported to them. The number of reports was greater than that of the Federal Aviation Administration's Service Difficulty Reports database, and less than the operators records.

Shortly after takeoff from runway 05L at Mexico City-Benito Juarez Airport, while in initial climb, the aircraft encountered windshear. It lost height and crash landed on the runway. Upon impact, the landing gear were torn off. Out of control, the aircraft veered off runway, lost its right wing and came to rest. All 56 occupants evacuated safely and the aircraft was destroyed.

While cruising at an altitude of 25,000 feet on a cargo flight from Yopal to Mitú, the crew was cleared to descend to 7,000 feet for an approach to runway 01 at Mitú-Fabio Alberto León Bentley Airport. Few minutes later, while descending at an altitude of 23,300 feet, the aircraft entered an uncontrolled descent and crashed in a mountainous and isolated area located about 135 km northwest of Mitú Airport. The wreckage was found 10 days later, on December 28, at coordinates N 002° 19' 15'' W 070° 47' 13''. The aircraft was totally destroyed and all three crew members were killed.
