Technical failure

The four engine airplane was completing flight LO007 from Montreal to Warsaw via New York-JFK. On final approach to Warsaw-Okecie Airport runway 15, the crew reported problems with the landing gears that seemed to be down but not locked. At a height of about 250 meters, the captain was cleared to initiate a go-around and increased engine power when the engine n°2 exploded, damaging the engine n°1. Debris damaged the rudder and elevator control cables, causing the aircraft to enter an uncontrolled descent. In a 20° nose-down attitude, the aircraft speed increased to 380 km/h when it crashed in an embankment located by the Okecie Fort, about 900 meters short of runway 15 threshold. The aircraft disintegrated on impact and all 87 occupants were killed. On board were 14 members of the US boxing team and 10 coaches as well as Anna Jantar, a Polish singer.

Shortly after takeoff, one of the engine failed. The airplane stalled and crashed by the runway. There were no casualties.

While in cruising altitude on a taxi flight from Norfolk to Roanoke, the pilot informed ATC about a double engine failure and elected to divert to the nearest airport. Shortly later, he decided to attempt an emergency landing when the airplane crashed in an open field. Both occupants were slightly injured and the aircraft was damaged beyond repair.

The aircraft was engaged in a scheduled service, designated Flight DR 4210, from Sydney to Temora and Condobolin, within the State of New South Wales. The scheduled departure time was 1845 hours. At 1844 hours the pilot of VH-AAV contacted Sydney Airport Clearance Delivery by radio and requested his airways clearance. The airways clearance issued was a Standard Instrument Departure (SID), titled '25 Katoomba Two'. That SID specified that radar headings would be assigned after take-off from Runway 25. The pilot correctly acknowledged the airways clearance. At 1848 hours the pilot contacted Sydney Ground Control and requested clearance to· taxi. This was granted and the aircraft was taxied to the holding point for Runway 25. The pilot reported to Sydney Aerodrome Control at 1858 hours that he was ready for take-off. Due to other traffic. the aircraft was not cleared to line up until 1906 hours. VH-AAV then entered Runway 25 and stopped about 50 metres from the threshold. At 1907 hours VH-AAV was cleared to 'maintain runway heading, maintain 3000 (feet), clear for take-off. This was correctly acknowledged and VH-AAV commenced takeoff. The aircraft became airborne and crossed the intersection with Runway 16/34, at a height of about 100 feet above ground level (AGL) at 1908:19 hours. The landing gear was retracted. Observers then noted the aircraft level off at about 150 feet AGL and commence a shallow banked turn to the left. As this was contrary to the departure instructions, Aerodrome Control was about to query the pilot when, at 1908:33 hours. he advised: ' ... we've lost er, the left engine. Request landing, ah, landing on runway three four immediately please.' This was acknowledged and Aerodrome Control cleared VH-AAV for a visual approach to a left base for Runway 34. During these transmissions, VH-AAV continued its left turn through approximately 90 degrees, onto a southerly heading. It had maintained a height of about 150 feet AGL and the left propeller was probably in the process of feathering. At 1908:44 hours, Aerodrome Control queried' ... do you have the seven two seven in sight on short final.' At 1908:49 hours, the pilot of VH-AAV replied, 'Affirmative'. The other aircraft referred to by Aerodrome Control was an Ansett Airlines of Australia Boeing 727, VH-RMO, which was on approach for Runway 34. Shortly after passing over the shore of Botany Bay, VH-AAV entered a steady descent and then levelled off just above the water. The left turn was continued and the aircraft converged towards the western side of the sea wall enclosing the extension of Runway 16/34. At 1908:50 hours, Aerodrome Control asked,' ... will your approach and landing be normal.' The reply, eight seconds later, was 'Alpha Alpha Victor negative'. At 1909:08 hours, Aerodrome Control activated the crash alarm system. In addition, VH-RMO was directed' ... go around, correction, st ... stay on the runway and expedite. We have a landing, er, right behind you ... one engine out.' The initial direction was made prior to visually assessing the Boeing ?27's situation, but when, during the transmission, it was noted that the aircraft was on the ground and well established in its landing roll sequence, the 'expedite' instruction was substituted. At 1909:20 hours, Aerodrome Control cleared VH-AAV to land. This was not acknowledged. The final segment of the flight was at an extremely low altitude and in a nose-high attitude. The right propeller, on at least one occasion, probably contacted the water and the tail either furrowed the water or induced a wake. VH-AAV struck the sea wall in a nose-up attitude, banking to the left and skidding to the right. The left wing of the aircraft disintegrated. The resultant fuel spillage ignited and a 'fire ball' explosion occurred. The right engine and the outboard section or the right wing both separated and were thrown across the ground adjacent to the runway. The remainder of the aircraft bounced over the sea wall, landed inverted on a taxiway and slid backwards. The accident occurred in daylight at 1909:22 hours. The aircraft was totally destroyed by impact forces and a post crash fire and all 13 occupants were killed.

The airplane departed Port-au-Prince Airport on an illegal flight to the US. About 45 minutes after takeoff, the crew declared an emergency and reported a fire on the right engine and right wing. He was cleared to return to Port-au-Prince when the airplane went out of control and crashed into the sea few km offshore. The aircraft was destroyed and all three occupants were killed.

En route from Yeniseysk to Motygino, while cruising at an altitude of 900 meters in the region of the Pogromnaya River, the engine failed. The crew attempted an emergency landing when the airplane struck trees and crashed in a wooded area located 8 km north of Novoangarsk. All occupants were rescued and the aircraft was damaged beyond repair.

Shortly after takeoff from Mandalay-Chianmyathazi (Annisaton) Airport, while in initial climb, the crew reported an engine failure and was cleared to return for an emergency landing. Following a circuit, on final, the airplane lost height and crashed on a tobacco factory. The airplane and the factory were totally destroyed. A passenger was seriously injured while 43 other occupants were killed. There were no casualties on the ground.

After takeoff from Columbus-Port Columbus Airport, while in initial climb, both engines suffered a partial loss of power. The airplane stalled, entered a spin and crashed in flames. The pilot, sole on board, was killed.

The aircraft was engaged in a local test flight at Bogotá-El Dorado Airport, carrying four crew members, two pilots and two engineers. After passing over runway 12 at an altitude of about 200 feet, the pilot was able to send a brief mayday message when the airplane banked left and crashed in flames. The aircraft was destroyed and all four occupants were killed.

On the day of the accident, Iranian air traffic controllers went on strike, which led to hundreds of domestic flights being cancelled. At 1600LT the strike was interrupted and flights resumed. At 1740LT, the airplane departed Mashad Airport on schedule service IR291 to Tehran-Mehrabad Airport with 120 passengers and a crew of eight on board. At 1852LT, ATC based at Tehran-Mehrabad Airport cleared the crew for a direct approach to runway 29. At 1905LT, the dispatcher instructed the crew to take a 360° heading to reach the non-directional beacon of Varamin. On approach, the copilot informed the captain that the VORTAC was giving a wrong radial course but the captain failed to respond to this message. At 1911LT, while descending in limited visibility due to night, snow falls and foggy conditions, the airplane struck the slope of a mountain located in the Alborz Mountain Range. The wreckage was found few hours later in a snow covered terrain about 29 km north of Tehran Airport. The aircraft disintegrated on impact and none of the 128 occupants survived the crash.
