This amended report explains the accident involving United Airlines flight 585, a Boeing 737-200, on its way from Denver to Colorado Springs, which crashed on March 3, 1991 near Colorado Springs Municipal Airport. Only after the crash of USAir 427 in 1994 and a similar incident with Eastwind 517 in 1996 the NTSB was able to pinpoint the cause of this crash: jammed rudder. The Boeing 737 has a history of rudder system-related anomalies, this finally solved the mystery of sudden jamming of the rudders of this aircraft.

On July 26, 2002, about 0537 eastern daylight time, Federal Express flight 1478, a Boeing 727-232F, on its way from Memphis International Airport to Tallahassee Regional airport, struck trees on short final approach and crashed short of runway 9 at the Tallahassee Regional Airport, Florida. The flight was operating as a scheduled cargo flight from Memphis, to Tallahassee. The captain, first officer, and flight engineer were seriously injured, and the airplane was destroyed by impact and resulting fire. Night visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan. The National Transportation Safety Board determines that the probable cause of the accident was the crew's failure to establish and maintain a proper glidepath during the night visual approach to landing. Contributing to the accident was a combination of the captain's and first officer's fatigue, the crew's failure to monitor the approach, and the first officer's color vision deficiency.

On December 29, 1972 an Eastern Air Lines' Lockheed L-1011, as Flight 401 on its way from John F. Kennedy International Airport, New York, to Miami International Airport, Miami, Florida, crashed at 2342 eastern standard time in the Everglades, approximately 18 miles west northwest of Miami International Airport. The aircraft was destroyed. There were 163 passengers and a crew of 13 aboard the aircraft, 99 people died in the crash. The flight was diverted because of problems with the nose landing gear The aircraft climbed to 2,000 feet while the crew attempted to correct the problem. Surviving passengers and crewmembers stated that the flight was routine and operated normally before impact with the ground. The National Transportation Safety Board determines that the probable cause of this accident, was preoccupation with a malfunction of the nose landing gear position indicating system distracted the crew's attention from the instruments and allowed the descent to go unnoticed.

On 2 May 2006 Armavia Flight RNV 967, an Airbus A320, was on its way from Zvartnots (Yerevan, Armenia) to Adler (Sochi, Russia). There were 113 occupants on board: 105 passengers (including 5 children and 1 baby), 2 pilots,1 aircraft engineer and 5 flight attendants. Upon approaching Sochi there was confusion in regard to the weather for the scheduled landing. Finally the captain decided to return to Zvartnots, a short while later he reconsidered his decision and started the approach to Sochi after all. Just before final landing air traffic control told the captain to abort the landing. At 22:13 the aircraft struck the water, it broke up on impact, killing all aboard. The investigation concluded that the crash of Armavia Flight 967 was a Controlled Flight Into Terrain (CFIT), specifically water, while conducting a climbing manoeuvre, after an aborted approach, along with inadequate control inputs from the Captain to Sochi airport at night with weather conditions below landing minimums for runway 06.

During the night of 04th May 2007, the B737-800, registration 5Y-KYA, operated by Kenya Airways as flight KQA 507 from Abidjan international airport (C te d'Ivoire), to the Jomo Kenyatta airport Nairobi (Kenya), made a scheduled stop-over at the Douala international airport (Cameroon). The weather was stormy. A number of departing planes decided to wait for the weather to improve. Kenya Airways, however, decided to depart. Shortly after take-off at about 1000 ft, the aircraft entered into a slow right roll that increased continuously and eventually ended up in a spiral dive. On the 5th May 2007 at approximately 0008 hrs, the airplane crashed in a mangrove swamp South-South/East of Douala. All 114 people on board were killed and the airplane was completely destroyed. The airplane crashed after loss of control by the crew as a result of spatial disorientation, after a long slow roll, during which no instrument scanning was done, and in the absence of external visual references in a dark night.

On October 31, 1999, EgyptAir flight 990, a Boeing 767-366ER, crashed into the Atlantic Ocean 60 miles south of Nantucket, Massachusetts. All 217 people on board were killed, and the airplane was destroyed. According to the Egyptian Investigation Team a mechanical defect is the most likely cause of the accident, there is no credible evidence to support a conclusion that the First Officer intentionally dove the airplane into the ocean in fact.

On April 27, 1976, American Airlines, Flight 625, a Boeing 727-95, operated as a scheduled passenger flight from Providence, Rhode Island, to Harry S Truman Airport, Charlotte Amalie, St. Thomas, Virgin Islands, with a stop at John F. Kennedy -International Airport, New York. The flight departed JFK at 1200 with 88 persons, including 7 crewmembers, aboard. At about 1510, during landing at the Harry S Truman Airport, Charlotte Amalie, St. Thomas, Virgin Islands, flight 625 overran the departure end of runway 9, struck the ILS antenna, crashed through a fence, and came to rest against a building located 1,040 feet beyond the end of the runway. The aircraft was destroyed, 35 passengers and 2 flight attendants were killed. The National Transportation Safety Board determines that the probable cause of the accident was the captain's actions and his misjudgment in initiating a go-around maneuver with insufficient runway remaining after a long touchdown.
