American Airlines Flight 965, a Boeing 757 registered N651AA, was a scheduled flight from Miami International Airport in Miami, Florida to Alfonso Bonilla Aragón International Airport in Cali, Colombia, which crashed into a mountain in Buga, Colombia on December 20, 1995, killing 151 passengers and 8 crew members.[1] The crash was the first U.S.-owned 757 accident and the highest death toll of any accident in Colombia. It is also the highest death toll of any accident involving a Boeing 757 at that time. It was surpassed by Birgenair Flight 301 which crashed in 1996 with 189 fatalities. Flight 965 was the deadliest air disaster involving a U.S. carrier since the downing of Pan Am Flight 103 in 1988.[2] Four passengers survived the crash, all of whom were seated within 2 rows of each other.[3]

The Colombian Special Administrative Unit of Civil Aeronautics investigated the accident and determined it was caused by navigational errors by the flight crew.[4]

Flight history

At that time, Flight 965 mainly carried people returning to Colombia for the Christmas holiday, vacationers, and businesspeople.[5] A winter storm in the northeast United States caused the airline to delay the departure of the airliner for thirty minutes to allow for connecting passengers to board the flight, so Flight 965 pushed back from gate D33 in Miami at 5:14 pm, and then taxied to runway 27R, but seasonal congestion caused the Boeing 757 to take off two hours late.[6] Some other passengers booked on Flight 965 missed the flight due to missed connections.[1]

The cockpit crew consisted of Captain Nicholas Tafuri and First Officer Donald Williams. The cabin crew consisted of Purser Pedro Calle and Flight Attendants Magdalena Borrero, Rosa Cabrejo, Teresa Delgado, Gilberto Restrepo, and Margaret Villalobos.[6]

Cali's air traffic controllers had no functional radar to monitor the 757 as the pilots flew the approach using the area's radio navigation aids and the airport's instrument approach system. Cali's approach uses several radio beacons to guide pilots around the mountains and canyons that surround the city. The airplane's flight management system already had these beacons programmed in, and should have, in theory, told the pilots exactly where to turn, climb, and descend, all the way from Miami to the terminal in Cali.[citation needed]

Since the wind was calm, Cali's controllers asked the pilots if they wanted to fly a straight-in approach to runway 19 rather than coming around to runway 01. The pilots agreed, hoping to make up some time. The pilots then erroneously cleared the approach waypoints from their navigation computer. When the controller asked the pilots to check back in over Tuluá, north of Cali, it was no longer programmed into the computer, and so they had to pull out their maps to find it. In the meantime, they extended the aircraft's speed brakes to slow it down and expedite its descent.[4]

By the time they found Tuluá's coordinates, they had already passed over it. In response to this, they attempted to program the navigation computer for the next approach waypoint, Rozo. However, the Rozo NDB was identified as R on their charts. Colombia had duplicated the identifier for the Romeo NDB near Bogotá, and the computer's list of stored waypoints did not include the Rozo NDB as "R", but only under its full name "ROZO". In cases where a country allowed duplicate identifiers, it often listed them with the largest city first. By picking the first "R" from the list, the captain caused the autopilot to start flying a course to Bogotá, resulting in the airplane turning east in a wide semicircle. By the time the error was detected, the aircraft was in a valley running roughly north-south parallel to the one they should have been in. The pilots had put the aircraft on a collision course with a 3,000-meter (9,800 feet) mountain.[7] The air traffic controller believed that some of the requests of the pilots did not make sense, but did not know enough non-aviation English to convey this.[8]

Crash

Twelve seconds before the plane hit the mountain, the Ground Proximity Warning System activated, announcing an imminent terrain collision and sounding an alarm. The captain and first officer attempted to climb clear of the mountain, but the deployed speed brakes reduced the rate of climb and the aircraft hit the mountain near its summit. Research has shown that the aircraft would probably have cleared the terrain if the crew had immediately retracted the speed brakes when the GPWS alarm sounded.[4]

Aftermath

Scavengers took engine thrust reversers, cockpit avionics, and other components from the crashed 757. The scavengers used Colombian military and private helicopters to go to and from the crash site. Many of the stolen unapproved aircraft parts re-appeared on the black market in Greater Miami parts brokers.[9] In a response, the airline published a 14 page list stating all of the parts missing from the crashed aircraft. The list included the serial numbers of all of the parts.[10]

In 1997 U.S. District Judge Stanley Marcus ruled that the pilots had committed "willful misconduct"; the ruling applied to American Airlines, which represented the deceased pilots.[11] The judge's ruling was subsequently reversed in June 1999 by the U.S. 11th Circuit Court of Appeals in Atlanta, which also overturned the jury verdict and declared that the judge in the case was wrong in issuing a finding of fault with the pilots, a role which should have been reserved for the jury only.[12]

American Airlines settled numerous lawsuits brought against it by the families of the victims of the accident. American Airlines filed a "third-party complaint" lawsuit for contribution against Jeppesen and Honeywell, who made the navigation computer database and failed to include the coordinates of Rozo under the identifier "R"; the case went to trial in United States District Court for the Southern District of Florida in Miami. At the trial, American admitted that it bore some legal responsibility for the accident. Honeywell and Jeppesen each contended that they had no legal responsibility for the accident. In June 2000, the jury found that Jeppesen was 30 percent at fault for the crash, Honeywell was 10 percent at fault, and American Airlines was 60 percent at fault.[13]

The flight route designation of the Miami to Cali route is now Flight 921 as a Boeing 737-800. Rozo NDB "R" has been replaced by Palma NDB "PL".

An improved ground proximity warning system, called enhanced ground proximity warning system, was introduced in 1996,[14] which could have prevented the accident.

Since 2002, all planes with more than six passengers are required to have an advanced terrain awareness warning system. No aircraft fitted with a TAWS/EGPWS suffered a controlled flight into terrain accident until July 28, 2010 when Airblue Flight 202 crashed into the Margalla Hills, Pakistan.[15]

Crash investigation and final report

The crash was investigated by the Special Administrative Unit of Civil Aeronautics (Aeronáutica Civil) of the Republic of Colombia,[4] with assistance from the U.S. National Transportation Safety Board (U.S. NTSB) as well as other parties, including the U.S. Federal Aviation Administration, Allied Pilots Association, American Airlines, Boeing Commercial Airplane Group and Rolls Royce Engines.

The Aeronáutica Civil prepared a final report of its investigation in September 1996, which was released through the U.S. NTSB.[16]

In its report, the Aeronáutica Civil determined the following probable causes of the accident:

  1. The flightcrew's failure to adequately plan and execute the approach to runway 19 at SKCL and their inadequate use of automation.
  2. Failure of the flightcrew to discontinue the approach into Cali, despite numerous cues alerting them of the inadvisability of continuing the approach.
  3. The lack of situational awareness of the flightcrew regarding vertical navigation, proximity to terrain, and the relative location of critical radio aids.
  4. Failure of the flightcrew to revert to basic radio navigation at the time when the FMS-assisted navigation became confusing and demanded an excessive workload in a critical phase of the flight.

In addition, the Aeronáutica Civil determined that there were the following contributing factors to the accident:

  1. The flightcrew's ongoing efforts to expedite their approach and landing in order to avoid potential delays.
  2. The flightcrew's execution of the GPWS escape maneuver while the speedbrakes remained deployed.
  3. FMS logic that dropped all intermediate fixes from the display(s) in the event of execution of a direct routing.
  4. FMS-generated navigational information that used a different naming convention from that published in navigational charts.

The Aeronáutica Civil's report also included a variety of safety-related recommendations to the following parties (number of individual recommendations in parentheses):[4]

Investigators later labeled the accident a Nonsurvivable event.

Dramatization

This incident was featured on the television series Air Crash Investigation in the episode "Lost", known in some countries as "Crash on the Mountain".

Notable passengers

  • Francisco Ferre Malaussena, Mariana Gomez de Ferre, and Felipe Antonio Ferre Gomez, the son, daughter-in-law, and grandson of former Miami mayor Maurice Ferre.[17][18]
  • Paris Kanellakis, a computer scientist at Brown University, died with wife María Teresa Otoya and children Alexandra and Stephanos.[17]
  • The survivors are Gonzalo Dussan Monroy, Michelle Dussan,[17][19] Mercedes Ramirez, and Mauricio Reyes. Gonzalo "Gonzalito" Dussan, Jr., Michelle Dussan's brother and Gonzalo Dussan's son, was initially found alive but died on the operating table due to internal injuries.[6] Gonzalo Dussan did not receive insurance benefits from the death of his companion and the mother of his children, Nancy Delgado, as Delgado and Dussan were not legally married.[20] Ramirez is a central character in Exit Row: The True Story of an Emergency Volunteer, a Miraculous Survivor and the Crash of Flight 965 by Tammy L. Kling.[21]
  • Crews found a small brown dog alive, inside a carrier in the cargo hold.[22] The dog was adopted by the Red Cross team in Cali, Colombia, for a few weeks (they re-named him "Milagro", which is Spanish for "miracle"), then an American Airlines employee who had worked the crash recovery in Cali adopted the dog and brought it to the United States.[23]

The U.S. encountered difficulty while trying to distinguish Americans from non-Americans, as many passengers held dual citizenships.[22]
