Landing (descent or approach)

The aircraft departed Libreville-Léon Mba Airport at 0911LT on a flight to Franceville with an intermediate stop in Port Gentil with 26 passengers and four crew members on board. Few minutes after takeoff, the crew informed ATC about technical problem and was cleared to return to Libreville. In excellent weather conditions, the aircraft overflew the runway then crashed in the sea about 100 metres offshore. Eleven occupants were rescued while 19 others were killed, among them one crew member.

After landing, the aircraft was unable to stop within the remaining distance. It overran, crossed an unpaved road and some ditches before coming to rest 250 meters further. All 16 occupants escaped uninjured while the aircraft was damaged beyond repair.

The aircraft was performing a cargo flight from Beni to Goma with 8 Congolese passengers and 4 Russians crew members on board. After takeoff from Beni, the captain reported technical problem with the left main gear but continued towards Goma. While descending to Goma Airport, he decided to divert to Kigali International Airport to make an emergency landing because of the gear problems. Upon landing, the aircraft bounced then veered off runway and came to rest. All 12 occupants were seriously injured and the aircraft was damaged beyond repair.

The airplane overran the runway after landing on runway 7. The passenger stated that he felt that the approach was "fast" and that the pilot was "behind the power curve" because of high
minimum en route altitudes in the area and that they had to "hustle down" during the descent. The passenger indicated that the flight crossed the runway threshold "maybe a bit more" that 10 knots above Vref and touched down about 10 knots above Vref. He said it was not a stabilized approach. Landing distance calculations and other evidence suggest that the lift dump panels did not extend after landing; however, the investigation did not determine the reason(s) for the lack of lift dump. No evidence was found of any failures affecting the lift dump or braking systems. Evidence and interview statements reveal that the pilot flew an unstabilized approach to the runway and landed well above target speed. The high landing speed was result of the pilot's excessive airspeed on the approach and a tailwind component of about 8 knots. Although the pilot landed the airplane within the touchdown area, the airplane's speed upon touchdown was about 17 knots above the prescribed speed. The flight's unstabilized approach and excessive speed should have prompted the pilot to initiate a missed approach.

While descending to Lukla Airport from the south following a cargo flight from Kathmandu, the crew encountered poor visibility due to clouds when, at an altitude of 11,600 feet, the aircraft struck the slope of a mountain located near the Lamjura Pass, in the Solukhumbu district. The wreckage was found west of the airport and all three crew members were killed.

Pickerel Arm Camps is located about 22 km south of Sioux Lookout, Ontario. It operates a main campsite at its water base and several remote fishing lodges. The company operates two float equipped de Havilland DHC-2 Beaver aircraft to fly guests and supplies to their remote sites. Seven guests of the company arrived at the water base on 18 May 2004, the day before their scheduled four-day fishing trip at Fawcett Lake, one of the remote lodges. Because the remote lodge was available, a decision was made to fly in that afternoon. The group was divided in two, and a group of three guests and all the supplies for the seven guests were to go in the first aircraft. The second group of four, with their personal baggage, was to follow in the company’s other Beaver. The occurrence aircraft, a de Havilland DHC-2 Beaver (C-GQHT, serial number 682) with one pilot and three camp guests on board, departed the company water base at approximately 1700 eastern daylight time on a day visual flight rules flight to Fawcett Lake. At approximately 1930, the pilot and the other four guests arrived in the second aircraft to discover that the first group had not arrived. The guests later found the accident aircraft overturned in the lake. Ontario Provincial Police divers recovered the bodies of the pilot and the three passengers. The aircraft sustained substantial damage. There was no fire.

While descending to Manaus-Eduardo Gomes Airport following an uneventful flight from Tefé, the aircraft was correctly established on the ILS when the crew was instructed by ATC to initiate a go-around and to follow a holding pattern as the priority was given to an ambulance flight. The crew made a left turn heading 060° and continued the descent after passing 2,000 feet when the aircraft struck the ground and crashed about 33 km from the airport. The aircraft disintegrated on impact and all 33 occupants were killed.

The pilot was finishing his third round-trip, Part 135 cargo flight. The first round trip began the previous evening, about 2150, and the approach back to the origination airport resulted in a landing on runway 15R at 2305. The second approach back to the origination airport resulted in a landing on runway 28 at 0230. Prior to the third approach back to the airport, the pilot was cleared for, and acknowledged a visual approach to runway 33R twice, at 0720, and at 0721. However, instead of proceeding to the runway, the airplane flew north of it, on a westerly track consistent with a modified downwind to runway 15L. During the westerly track, the airplane descended to 700 feet. Just prior to an abeam position for runway 15L, the airplane made a "sharp" left turn back toward the southeast, and descended into the ground. Witnesses reported the airplane's movements as "swaying motions as if it were going to bank left, then right, and back left again," and "the nose...pointing up more than anything...but doing a corkscrew motion." Other witnesses reported the "wings straight up and down," and "wings vertical." Tower controllers also noted the airplane to be "low and tight," and "in an unusually nose high attitude close to the ground. It then "banked left and appeared to stall and then crashed." A post-flight examination of the wreckage revealed no evidence of mechanical malfunction. The pilot, who reported 6,800 hours of flight time, had also flown multiple round trips the previous two evenings. He had checked into a hotel at 0745, the morning prior to the accident flight, checked out at 1956, the same day, and reported for work about 1 hour before the first flight began.

Flight 5401 departed Mayagüez, Puerto Rico, for San Juan about 14:15. The captain was the nonflying pilot for the flight, and the first officer was the flying pilot. The takeoff, climb, and en route portions of the flight were uneventful. At 14:37, as the flight approached the San Juan traffic area, the ATIS reported that winds were 060 degrees at 17 knots and gusting at 23 knots. Shortly thereafter, the captain briefed a Vref (the minimum approach airspeed in the landing configuration before the airplane reaches the runway threshold) of 95 knots and told the first officer to "stand by for winds." At 14:43 SJU Terminal Radar Approach Control cautioned the pilots of possible wake turbulence from a preceding Boeing. The captain told the first officer to slow down to about 140 kts. At 14:46, the local controller cleared the airplane to land on runway 08. The first officer turned the airplane left toward runway 08 and transitioned to the visual approach slope indicator. At 14:49, the captain stated, "you better keep that nose down or get some power up because you're gonna balloon." The airplane descended below the glideslope, causing a GPWS "glideslope" alert. The airplane was about 45 feet above ground level and traveling at 110 knots indicated airspeed when it crossed the runway 08 threshold. After the airplane crossed the runway threshold, the captain stated, "power in a little bit, don't pull the nose up, don't pull the nose up." At 14:49:39, the captain stated, "you're ballooning," and the first officer replied, "all right." The airplane touched down for the first time about 14:49:41 and about 1,600 feet beyond the runway 08 threshold with vertical and lateral loads of about 1.3 Gs and -0.10 G, respectively. Upon touchdown the captain stated, "get the power," and, 1 second later, "my aircraft." The first officer responded, "your airplane." The airplane had skipped to an altitude of about 4 feet and touched down again two seconds later about 2,200 feet beyond the runway 08 threshold. The airplane then pitched up to an angle of 9° while climbing to an altitude of 37 feet and the engine torque increased from 10 to 43 percent. About 14:49:49, the pitch angle decreased to -3°, and the engine torque started to decrease to 20 percent with the pitch angle decreasing to -10°. The airplane touched down a third time about 14:49:51 at a bank angle of 7° left wing down and about 3,300 feet beyond the runway 08 threshold and with vertical and lateral loads of about 5 Gs and 0.85 G. The ATR pitched up again to 24 feet and landed a fourth time about 14:49:56 (about 15 seconds after the initial touchdown) and about 4,000 feet beyond the runway 08 threshold. This time the airplane pitched down to -7° and that it was banked 29° left wing down. The airplane came to a complete stop on a grassy area about 217 feet left of the runway centerline and about 4,317 feet beyond the runway threshold.

Following an uneventful flight from Bogotá-El Dorado Airport, the crew started the approach to Carepa-Los Cedros Airport, the copilot was the pilot-in-command. On final approach, the captain took over controls and continued the descent when the GPWS alarm sounded seven times. For unknown reasons, the captain failed to respond to this situation and did not proceed with any corrective actions. On short final, at a height of about 200 feet, one of the engine failed. The crew failed to follow the published procedures, causing the aircraft to stall and to crash about 100 metres short of runway 33. Two passengers were seriously injured while five other occupants were killed.
