Landing (descent or approach)

The four engine airplane was completing a humanitarian flight to Kisangani on behalf of 'Médecins Sans Frontières'. After touchdown, the aircraft was unable to stop within the remaining distance, overran and came to rest, bursting into flames. All seven crew members escaped uninjured and the aircraft was destroyed.

The airplane impacted heavily wooded terrain after experiencing a dual engine failure due to a reported lightning strike. The pilot received a weather brief that included information concerning a Convective Sigmet and a Severe Weather Watch. The weather briefer informed the pilot that a route to the southeast would keep the flight out of the heavy weather, and that, "... you'll get clobbered if you go due east." After departure, the pilot requested a turn to the northeast to stay clear of weather. While in the climb, the flight was advised of a Weather Watch that covered the area of their flight. The CVR revealed that Continuous Ignition was not selected prior to encountering turbulence. About 23 minutes after takeoff, the airplane was climbing at about 30,800 feet msl when the pilot reported a dual engine failure due to a lightning strike. The CVR indicated one engine quit and the second quit about two seconds later. The copilot established a 170 kts descent airspeed for "best glide." The airplane was vectored near a level 5 thunderstorm during the emergency descent. Two air starts were attempted when the airplane's altitude was outside of the air start envelope. Two more air starts were attempted within the air start envelope but were unsuccessful. The minimum airspeed for an air restart is 160 kts and the maximum speed for air start is 358 kts. The CVR indicated that the pilots did not call for the airplane's checklist, and no challenge and response checklists were used during the emergency descent. The CVR indicated the pilots did not discuss load shedding any of the electrical components on the airplane. The CVR indicated the hydraulic system cycled twice during the emergency descent and the landing gear was lowered using the hydraulic system during descent. During the descent the pilots reported they had lost use of their navigation equipment. The airplane impacted the terrain located about 166 nautical miles from the departure airport on a bearing of 083 degrees. No preexisting engines or airframe anomalies were found.

For unknown reasons, the aircraft belly landed at Batajnica AFB and came to rest. There were no casualties but the aircraft was damaged beyond repair.

On August 12, 2000, about 1115 eastern daylight time, a Beechcraft B200, N3199A, registered to and operated by Great Texas Food Inc. as a Title 14 CFR Part 91 personal flight, ran off the side of the runway during landing in Spanish Cay, Bahamas. Visual meteorological conditions prevailed at the time and a visual flight rules flight plan was filed. The private-rated pilot and the two passengers received no injuries. The flight originated from Fort Lauderdale, Florida, the same day, about 1030. The pilot stated that he made an uneventful landing and as he applied the brakes, the left brake did not respond. He stated that he lost control of the aircraft and exited the runway from the right side and impacted a berm. The right landing gear collapsed, the left wing and the front fuselage incurred substantial damage.

The twin engine aircraft departed Zweibrücken Airport on a VFR flight to Egelsbach, carrying two passengers and one pilot. Following an uneventful flight at an altitude of 5,000 feet and while approaching the destination, the pilot informed ATC about technical problems and elected to divert to Griesheim-August-Euler Airport. On short final, while completing a left turn, the aircraft stalled and crashed 160 metres short of runway 25 threshold, bursting into flames. The aircraft was destroyed and all three occupants were killed.

Examination of the area of the fire origin revealed that relay R2-53, the left heat exchanger cooling fan relay, was severely heat damaged, as were R2-54 and the other relays in this area. However, the R2-53 relay also exhibited loose terminal studs and several holes that had burned through the relay housing that the other relays did not exhibit. The wire bundles that run immediately below the left and right heat exchanger cooling fans and the ground service tie relays exhibited heat damage to the wire insulation, with the greatest damage located just below the R2-53 relay. The unique damage observed on the R2-53 relay and the wire damage directly below it indicates that fire initiation was caused by an internal failure of the R2-53 relay. Disassembly of the relay revealed that the R2-53 relay had been repaired but not to the manufacturer's standards. According to the manufacturer, the damage to the relay housing was consistent with a phase-to-phase arc between terminals A2 and B2 of the relay. During the on-scene portion of the investigation, three of the four circuit breakers in the left heat exchanger cooling fan were found in the tripped position. To determine why only three of the four circuit breakers tripped, all four were submitted to the Materials Integrity Branch at Wright-Patterson Air Force Base, Dayton, Ohio, for further examination. The circuit breakers were visually examined and were subjected to an insulation resistance measurement, a contact resistance test, a voltage drop test, and a calibration test (which measured minimum and maximum ultimate trip times). Testing and examination determined that the circuit breaker that did not trip exhibited no anomalies that would prevent normal operation, met all specifications required for the selected tests, and operated properly during the calibration test. Although this circuit breaker appeared to have functioned properly during testing, the lab report noted that, as a thermal device, the circuit breaker is designed to trip when a sustained current overload exists and that it is possible during the event that intermittent arcing or a resistive short occurred or that the circuit opened before the breaker reached a temperature sufficient to trip the device.

The twin engine aircraft was completing a local test flight at Halle-Oppin Airport. For unknown reasons, it belly landed and came to rest. All three occupants escaped uninjured while the aircraft was damaged beyond repair.

The flight had proceeded without incident until a visual approach was made to the destination airport, but a landing was not completed because of poor visibility due to ground fog. The pilot then requested vectors to another airport, and was advised by ATC that he was below radar coverage, and he could not be radar identified. The pilot stated he would proceed to a third airport; he was given a heading, instructed to proceed direct to the airport, and report the field in sight. He was told to over-fly the airport, and might be able to descend through a clearing in the clouds. An inbound air carrier flight reported instrument meteorological conditions on the final approach to a parallel runway. At a location of 1.13 miles east of the airport, the flight, for no apparent reason, turned south, away from the airport. The last radio contact with pilot was after ATC told him his heading was taking him away from the airport and he said he was turning back. The last known position of N201RH was 1.95 miles southeast of the airport, at 500 feet MSL. According to the statement of the passenger that was sitting in the co-pilot's seat, "...all we could see were city lights and darkness underneath us. We were in a right turn, when I saw the trees and subsequently hit it." According to the pilot's log book and FAA records revealed a limitation on his commercial pilot certificate prohibited him from carrying passengers for hire at night and on cross-country flights of more than 50 nautical miles. The records did not show any instrument rating. As per the entries in his personal flight logbook, he had accumulated a total of 1,725.2 total flight hours, 1,550.9 total single engine flight hours, and 184.3 total flight hours in multi-engine aircraft of which 145.6 hours were in this make and model airplane. In addition, the logbooks showed that he had a total of 487.3 cross country flight hours, 61.9 total night flight hours, and 21.6 simulated instrument flight hours.

The twin engine aircraft departed New Delhi-Indira Gandhi Airport on an ambulance flight to Kulu-Bhuntar, carrying three doctors and two pilots. While descending to Kulu-Bhuntar Airport in IMC conditions, the crew failed to realize his altitude was insufficient when the aircraft struck the slope of a mountain located 20 km from the destination airport. The aircraft was destroyed and all five occupants were killed.

Airwave flight 9806, a G-159 Gulfstream I, was flying IFR from Toronto (YYZ) to Montreal-Dorval (YUL). When it was on final for runway 06R, the pilot reported a problem with the landing gear. The crew recycled the gear and performed the emergency extension procedure unsuccessfully before trying various flight manoeuvres to free the gear. They then circled Montreal until minimum fuel was reached, declared an emergency and landed. On landing, the aircraft veered to the left and came to a halt 60 feet from the runway. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
