Landing (descent or approach)

The crew was performing a flight from Travis AFB to Tachikawa AFB with intermediate stops at Hickam Field and Wake Island, carrying a load of various goods. While approaching Tachikawa AFB in poor weather conditions, the four engine aircraft struck the slope of Mt Ōyama (1,252 metres high) located 24 km west of the airbase. The aircraft disintegrated on impact and all eight occupants were killed.

The crew was engaged in a local training flight at Spokane AFB, consisting of visual and instruments approaches and landings. While approaching runway 23, at a distance of about three miles from the threshold, the crew cancelled his instruments approach to continue on visual mode. In the mean time, the second B-52 registered 56-0661 which was on second position must switch from visual mode to instruments approach procedures. To follow the approach procedures and as both crews were not coordinated, the approach controller instructed the first crew to gain altitude while turning to the right and instructed the second crew to reduce his altitude while turning to the left. Few seconds later, at an altitude of 900 feet, both aircraft collided and crashed. On board 56-0681, five crew members were killed while two others were seriously injured. On board 56-0661, only one crew survived, all eight others have been killed.

En route to Madras, the primary hydraulic system failed. The crew failed to identify the failure properly and after touchdown at Madras Airport, the brake systems were partially inoperative. Unable to stop within the remaining distance, the airplane overran, struck obstacles, lost its undercarriage and came to a halt. All 31 occupants were evacuated safely while the aircraft was considered as damaged beyond repair.

Clearance was given for the route segment PPRF - PPKG at the approved altitude of 1 800 metres. Upon reaching the position Nazaré, the pilot descended without clearance to 1 200 metres and passed over the PPKG facility at 1000 metres, or 200 metres below the minimum altitude provided for initiating the procedure as prescribed by the Directorate of Air Routes. Having passed over the facility, the pilot consulted the procedure for PPKG and replaced it in the file. When the copilot asked him whether it should not be kept out, he said no, as he already knew it by heart. The procedure was initiated normally, the aircraft returning on a heading unknown to the Investigating Commission until it was at 520 metres (critical altitude 647 metres), when vertical visual contact with the runway was established; but it was not possible to come in, the aircraft having passed the critical point and being over the runway. The pilot tried to enter the traffic visual, so as not to lose sight of the runway, but this proved impossible on reaching final approach, with the result that the landing starting the return, on heading 200 degrees, he began to descend, turning on the aircraft lights. After a few moments of flight, the copilot tried unsuccessfully to obtain visual reference by looking outside. At this time he felt a violent impact and heard the pilot shout that he was "hitting". Two crew and eleven passengers were killed, and two crew and three passengers were seriously injured in the accident. The inbound heading of 200 degrees observed by the copilot and checked by the Investigating Commission showed that the procedure carried out by the pilot was not in accordance with that indicated in the approach chart approved by the Directorate of Air Routes. It was also found that at the time vertical visual contact with the runway was established, the aircraft was at most 40 metres from the ground, despite the fact that the meteorological information supplied by the Loide station at PPKG was ceiling 130 metres with visibility 6 km.

The Viking took off from London Airport at 0554 hours GMT with a crew of 3 for a flight to Nice, Brindisi, Athens and Tel Aviv. Fifteen minutes later the cap tain informed London Airport that he had engine trouble and wished to return to Blackbushe. During the return flight the aircraft initially maintained 7,000 feet. Clearance was given to descend to 3000 feet but the descent was apparently continued to 1,000 feet without informing control. Shortly afterwards the aircraft reported "having difficulty maintaining height" and six minutes later, at 0632LT, it crashed in Southall, about 3 miles from the airport. The aircraft was totally destroyed upon impact as well as several houses. All three crew members and four people on the ground were killed. Fifteen other people on the ground were injured.

The twin engine aircraft departed Tuxtla Gutierrez Airport at 0915LT for a 30 minutes flight to Yajalón. While approaching Yajalón Airport, the airplane collided with a second Anson registered XB-YUZ and also operated by Servicios Aéreos de Chiapas. Inbound from San Cristóbal de Las Casas, the second Anson was carrying four passengers and a crew of two. Following the collision, both aircraft dove into the ground and crashed in a prairie. All 17 occupants on both aircraft were killed. The exact circumstances of the collision remains unclear.

On final approach to Navegantes-Itajaí Airport, the airplane was too high and the captain decided to reduce the engine power to bring the aircraft in a steep descent. On short final, the airplane stalled, struck a building, lost several elements and eventually crashed short of runway threshold. There were no injuries but the airplane was damaged beyond repair.

During a night approach to Nantucket, the aircraft went through an area of fog. The crew decided to continue the approach when the airplane struck the ground, crashed and burned about 1,450 feet short of runway 24. All three crew members and 22 passengers were killed while nine others were injured, some of them seriously.
