Circumstances:
After touchdown on a wet runway at Manaus-Eduardo Gomes Airport, the four engine airplane deviated to the right, causing the right main gear to struck runway lights. Upon impact, the right main gear was torn off and the airplane came to rest. All three crew members escaped uninjured while the aircraft was damaged beyond repair. It was reported that the crew landed at an excessive speed of 148 knots on a wet runway due to heavy rain falls. It may be possible that the aircraft suffered aquaplaning after touchdown.

Circumstances:
The four engine airplane departed Brussels-Zavantem Airport runway 02 at 0929LT on a charter flight to Tenerife-Sur Reina Sofia with 110 passengers and a crew of seven on board. While climbing to an altitude of 7,000 feet, the engine n°3 exploded and caught fire. The crew declared an emergency and was cleared to return for a landing on runway 25L. After the fire was contained and while completing a last turn on final, the airplane was approaching too fast and overshot so the pilot decided to land on runway 25R. After touchdown, reversers on engine n°1 and 4 were activated and the crew initiated an emergency braking procedure. Nevertheless, the captain considered the remaining distance as insufficient and decided to steer the aircraft to the left of the runway where it came to rest. All 117 occupants were quickly rescued and the aircraft was damaged beyond repair.
Probable cause:
It was determined that the explosion of the engine n°3 was the consequence of the disintegration of a blade located on the 10th stage of the compressor due to fatigue cracks. The following contributing factors were reported:
- Approach completed with one engine inoperative,
- The total weight of the aircraft was above the max allowable weight upon landing,
- The approach speed was too high,
- The crew failed to use the brakes properly.

Circumstances:
On final approach to runway 12, the airplane entered a zone of heavy rain falls and dense fog. The pilot-in-command probably lost visual contact with the runway and its lighting system, causing the aircraft to descend until it struck the ground. Upon impact, the airplane lost its undercarriage and came to rest, broken in several pieces and bursting into flames. All four crew members were injured.

Circumstances:
Following an uneventful cargo flight from Paris-Orly Airport, the crew started the descent to Douala Airport in marginal weather conditions. On short final, the airplane encountered low level windshear. Control was lost and the aircraft banked left, causing the left wing to struck the runway surface. Upon impact, the left main gear was torn off as well as both engines n°1 and 2. The aircraft veered off runway to the left, made a 270° turn then came to rest. All three crew members escaped with minor injuries while the aircraft was damaged beyond repair, the left wing being partially torn off.
Probable cause:
Loss of control on short final due to windshear.

After takeoff from Singapore-Paya Lebar Airport, the crew retracted the landing gear and continued to climb. At a height of about 100 feet, the captain decided to abandon the takeoff and landed back on the runway. The airplane landed on its belly and slid for about 2,000 feet then veered to the right and came to rest. All 78 occupants were evacuated safely while the aircraft was damaged beyond repair. It is believed that all four engines lost power during initial climb for unknown reasons. The exact cause of the accident remains undetermined. The Authorities of Singapore reported that the flight engineer committed suicide a day later, jumping out the window from his hotel.

Upon impact, two engines were torn off and out of control, the aircraft crash landed and came to rest in flames. 82 occupants escaped uninjured while 51 others were injured. Two passengers were killed. The aircraft was partially destroyed by fire.
Probable cause:
Wrong approach configuration on part of the crew who failed to follow the approach checklist. A lack of crew coordination led the aircraft descending below the glide.

Circumstances:
The airplane was completing a schedule service from Kano to Karachi with an intermediate stop at Jeddah, carrying 145 passengers and a crew of 11. It departed Jeddah-King Abdulaziz Airport at 0129LT and continued to climb by night and good weather conditions. While cruising at an altitude of 37,000 feet, the captain informed ATC about an in-flight fire and was cleared to descent to 30,000 feet then 4,000 feet at his discretion. Seventeen minutes later, the situation on board became very critical with heavy smoke spreading in the cabin and the crew declared an emergency. While attempting an emergency landing in a desert area, the airplane struck the ground and disintegrated on impact. The wreckage was found about 48 km north of At Ta'if, in a rocky area. None of the 156 occupants survived the crash.
Probable cause:
An in-flight fire in the cabin area which, through its intensity and rapid extension, resulted in panic among the passengers and smoke in the cockpit, eventually incapacitating the flight crew. The cause of the cabin fire was not determined. It was considered that the origin of the cabin fire could have been a leaking gasoline or kerosene stove, carried aboard by Haj pilgrim passengers. Pressure differential could have caused a poorly sealed gasket to leak fuel. A second possibility is an electrical fire, but the rapid extension of the fire was considered difficult to explain because of the electrical circuit protection devices of the Boeing 707. Sabotage was considered as another possibility, but no evidence of use of an incendiary device was found.
