Landing (descent or approach)

After landing on runway 28R at Caracas-Maiquetía-Simón Bolívar Airport, the aircraft deviated to the left. It eventually veered off runway to the left and went down a slope, coming to rest with its nose gear torn off. All 54 occupants evacuated safely and aircraft was damaged beyond repair.

The aircraft departed Kathmandu-Tribhuvan Airport at 0651LT on a regular schedule service to the Lukla-Tenzing-Hillary Airport. On approach to runway 06, the crew encountered poor visibility due to foggy conditions. Despite the pilot did not establish any visual contact with the ground, he continued the approach when, on short final, the aircraft struck a rock and crashed just below the runway 06 threshold, bursting into flames. The captain was seriously injured while 18 other occupants were killed, among them 12 Germans, 2 Australians and 5 Nepalese.

The accident aircraft Boeing 737-3Y0 EI-DON, was operated by KD Avia on a flight from Kaliningrad, Russia to Barcelona, Spain and return. Flight KD793 to Barcelona was uneventful. The return flight, KD794, departed at 16:18 with 138 passengers and six crew members on board. The copilot was Pilot Flying, the captain was Pilot Monitoring. The en route part of the flight was uneventful. As the flight was descending to Kaliningrad at night in heavy rains and with gusty crosswind. During the descent flaps were first selected at 1° and thereafter to 5°. As the flaps were transitioning to this position, a flap asymmetry warning caught the attention of the crew. At 19:00 hours the captain took over control and selected flaps to 2°, the position at which there was no asymmetry warning. The crew then contacted the controller at Kaliningrad and reported that they had flap problems. As the descent was continued, the copilot performed the necessary calculations for a landing with flaps at 2°. At 19:09 the cabin crew was warned to prepare for a high-speed landing. Using the QRH to work the flap issue, the co-pilot activated the 'flap inhibit' and 'gear inhibit' switches. This "incorrect" action effectively disconnected the ground-proximity warning system (GPWS). At 19:11 it was established that the landing speed would be Vref +30, leading to a planned landing speed of 161 knots. At 19:14 the Landing Gear Warning Horn sounded due to the combination of power and flaps setting with the fact that the landing gear had not been selected down. This warning was cancelled by the crew. When the engine power was reduced to idle, the Landing Gear Warning Horn sounded again. This time the crew did not pay attention to the warning and continued to land. The airplane performed a gear up landing, sliding for 1440 m before coming to rest on the runway. The flap asymmetry issue was caused by a faulty Flap Position Transmitter. The flaps had extended to the commanded position, but the system incorrectly detected an asymmetry issue. This issue had occurred previously on EI-DON. The sensor had been replaced prior to departure from Kaliningrad that same day.

The pilot was approaching his home airport under dark night conditions. He reported that he was five miles from the airport and adjusted the airport lighting several times. He made no further radio calls, though his normal practice was to report his position several times as he proceeded in the landing pattern. The airplane approached the airport from the southeast in a descent, continued past the airport, and adjusted its course slightly to the left. One witness reported observing the airplane enter a left turn, then pitch down, and descend at a steep angle. The airplane impacted terrain in a steep left bank and cart wheeled. An examination of the airframe, airplane systems, and engine revealed no pre-impact anomalies. Flight control continuity was confirmed. The pilot had flown eight hours and 30 minutes on the day of the accident, crossing two time zones, and had been awake for no less than 17 hours when the accident occurred. The accident occurred at a time of day after midnight in the pilot's departure time zone. Post-accident toxicology testing revealed doxylamine and amphetamine in the pilot's tissues. The pilot had been diagnosed with attention deficit hyperactivity disorder (ADHD) almost five years prior to the accident and had taken prescription amphetamines for the disorder since that diagnosis. The FAA does not medically certify pilots who require medication for the control of ADHD. At the time of the accident, the pilot's blood level of amphetamines may have been falling, and he may have been increasingly fatigued and distracted. The use of doxylamine (an over-the-counter antihistamine, often used as a sleep aid) could suggest that the pilot was having difficulty sleeping.

Upon landing at Lokichoggio Airport, the airplane banked right, causing the right propeller and the right wing to struck the runway surface. The aircraft slid for few dozen metres before coming to rest. There were no injuries while the aircraft was damaged beyond repair.

On approach to Tbilisi Airport by night, the aircraft's speed was excessive while passing over the inner marker at a height of 204 feet. Upon landing, the aircraft hit the ground with a positive aerodynamic force estimated between 1,81 and 1,97 G. The aircraft bounced several times and eventually hit the ground with a positive aerodynamic force of 4,82 G. The nose gear collapsed and punctured the cockpit floor. Then the aircraft slid for few dozen metres before coming to rest. There were no injuries while the aircraft was damaged beyond repair.

According to radar and Global Positioning System data, the pilot overflew the airport from the southwest and turned to the west to maneuver into position for landing on runway 9. Several witnesses observed the airplane to the west of the airport at a low altitude, appearing to enter a turn that was followed by a "rapid descent" and impact with the ground. The ground scars and
damage to the airplane were consistent with a near-vertical descent and impact. An examination of the airplane and its systems revealed no preaccident anomalies. The moon was obscured by an overcast sky and dark night conditions were prevalent.

On September 13, 2008 an Aeroflot –Nord flight crew (Captain and copilot), were conducting a scheduled domestic passenger flight n°AFL821 on a B737-505 aircraft, registration VP-BKO, from Moscow (Sheremetyevo, UUEE) to Perm (Bolshoye Savino, USPP). Apart from the two-member flight crew there were 4 flight attendants and 82 passengers on board, which makes a total of 88 people, including 66 citizens of the Russian Federation, 8 citizens of Azerbaijan, 1 citizen of Byelorussia, 1 of Germany, 1 of Italy, 1 of China, 1 of Latvia, 1 of Turkey, 1 of Uzbekistan, 5 citizens of Ukraine and 2 of France. According to the load sheet, the aircraft payload (cargo and passengers) was 8079 kg. The takeoff weight was ~54000 kg (with the max TOW of 60554 kg), the CG was at 20.61 % MAC, which was within the B-737-500 FCOM limitations. The calculated landing weight was 49700 kg (with the maximum of 49895 kg), and the CG was at 21.9 % MAC, which was also within the B737-500 FCOM limitations. The pre-flight briefing was conducted in due time and in compliance with the standard procedures. All the crew members passed medical check at the medical office of Aeroflot – Russian Airlines on September 13, 2008 at 1948 hrs and got permissions to fly. On the basis of the dispatch information (aircraft condition, aeronautical information, weather information, aircraft load data and operational flight plan) the PIC at 1955 hrs made a decision to fly. The takeoff was performed at 2113 without delay. The climb and level flight at FL290, 9,100 metres were conducted without any deviations. At 2245 hrs the crew started descent from the flight level to waypoint Mendeleyevo (940 MN). After passing over Mendeleyevo, in compliance with the Perm Approach Control instruction, the aircraft flew via the outer marker (705 PX) of Runway 21 which is the initial approach fix (IAF) for Runway 21 (heading 212° magnetic). After passing over the RWY with heading 110° M, the crew, following the Controller’s instruction, turned right for back course and started maneuvering for ILS approach to Runway 21. After the base turn, approaching the landing course at 600 m with both autopilot and autothrottle disengaged, the aircraft started climbing up to 1300 m, rolled 360° over the left wing and collided with the ground. The aircraft was totally destroyed and partly burnt in the ground fire. All passengers and crew members on board died due to the ground impact. The accident occurred at 2310 hrs 12.4 km from aerodrome reference point (ARP) of Perm Airport, azimuth 60° M. Accident site elevation is 153 m.

Damaged beyond repair following structural failure due to fatigue upon landing at Efogi, PNG. There were no injuries but the aircraft was damaged beyond repair and dismantled.

The aircraft departed Kinshasa on a humanitarian flight to Goma with intermediate stops in Mbandaka, Kisangani and Bukavu. While approaching Bukavu-Kamembe Airport, the crew encountered poor visibility due to bad weather conditions. At an altitude of about 10,800 feet, the aircraft struck the slope of Mt Kahuzi located some 15 km northwest of Bukavu. The wreckage was found a day later in a wooded area. All 17 occupants were killed, among them emissaries.
