Vickers Viscount

Viscount aeroplane type 803, registration: EI-AOM departed from Cork Airport at 10.32 hours en route for London operating as Aer Lingus Flight 712. The take-off was normal. The flight was cleared by Air Traffic Control to proceed via Airways Blue 10, Green 1 at flight level 170 (17,000'). At 10.38, when the aeroplane had passed through 7,000', clearance on course to Tuskar was given. At 10.40, after the flight had reported it was by Youghal at 7,500' climbing to 17,000', ATC Cork suggested that if desired, the flight could route direct to Strumble. No direct acceptance of this suggestion was received. At 10.57.07 the flight reported "by Bannow (a reporting point on the route at 51º 68' N - 06º 12' W) level 170 (17,000') estimating Strumble at 03". The flight was instructed to change to the London Airways frequency of 131.2, and this was acknowledged by the reply "131.2". The time of this call was 10.57.29. At 10.58.02, London Radar intercepted a call (garbled and simultaneous with another call) which appeared to be, and was later confirmed as "Echo India Alpha Oscar Mike with you", and eight (8) seconds later, a call was intercepted which was interpreted as "Five thousand feet descending spinning rapidly". This call was also heard by another Aer Lingus aircraft en route Dublin-Bristol (The word "Five" was later, after repeated acoustic analysis, interpreted as more likely to be the word "twelve".) This was the last call received from the aircraft. At 11.10, London ATC advised Shannon ATC that they had no radio contact with EI-AOM. At 11.13 London advised Shannon that they had requested Aer Lingus Flight EI 362 (Dublin-Bristol) to search west of Strumble. This flight descended to 500' in good visibility, but saw nothing. Between 11.13 and 11.25, efforts were made to make radio contact with the flight, with no result, and at 11.25 a full alert was declared. At 12.36 a report from the U.K. was received by Haulbowline that wreckage had been sighted in position 51º 57' N, 06º 10' W Rosslare Lifeboat was proceeding, but two surface vessels within 4 nautical miles of this position saw nothing. At 12.52 hours the Air Corps reported that they had dispatched a Dove aeroplane and a helicopter to search. At 13.10 hours there were ten aircraft from the U.K. in the search area. At 15.30 hours the reported sighting of wreckage was cancelled. Nothing positive was discovered on this day. On 25 March 1968, at 06.15 hours, the search was resumed by aircraft and ships from the U.K., and at 12.41 hours, wreckage was sighted and bodies recovered from a position 6 nautical miles north-east of Tuskar Rock. More floating wreckage was reported scattered for a further 6 nautical miles north-west of this point. The Irish Naval Service ship, L.E. Macha, which had been on patrol off the north-west coast, joined in the search on 26 March 1968, and took over duty as Search Controller. A total of 13 bodies was eventually recovered in the search during the next few days, together with a quantity of light floating wreckage-mostly cabin furnishings, and some baggage, seat cushions, and the wheels and inner cylinder from the port main landing gear. One additional body was recovered later. The position of the main wreckage remained obscure in spite of prolonged and diligent search by sonar equipped ships of the British Navy and trawling by Irish trawlers-"Glendalough" from Kilmore Quay and "Cu na Mara" of the Irish Fisheries Board (An Bord Iascaigh Mhara). Eventually, on 5 June 1968 "Glendalough" hauled in position 1.72 nautical miles from Tuskar Rock with Tuskar bearing 280º, in 39 fathoms and brought up a quantity of positively identifiable wreckage. The "Cu na Mara" in the same location also brought up wreckage. On the following day more wreckage was brought up by these trawlers, and divers from H.M.S. Reclaim confirmed a mass of wreckage "like a scrap yard" in this position. Subsequent salvage operations confirmed that a major portion of the aircraft at least was located here. Two eyewitnesses, one a sailor on a coastal vessel, who thought he had seen an aircraft crash into the sea but did not report it at the time, and another witness on shore, who saw a splash in the sea near the Tuskar Rock, gave the time as between 11.10 and 11.15. The position lines of these two witnesses approximately cross the location where the main wreckage was eventually found. The aircraft was totally demolished by violent impact with the sea. The bulk of the wreckage was found in 39 fathoms of water with all parts lying in close proximity. About 60-65% of the aircraft (by weight) was recovered, and included the major parts of three engines, a few parts of the fourth, and all four propellers, the almost complete primary structure of the wings from tip to tip, and the fin and rudder. None of the wreckage displayed any evidence of fire or explosion. No part of the tail planes or elevators were recovered, with the exception of small portions of the spring tab and trim tab. The recovered wreckage revealed extensive damage to the whole structure, which virtually disintegrated.

After touchdown at Akron-Canton Airport, the four engine airplane encountered difficulties to stop within the remaining distance. It overran, lost its undercarriage and went down an 23 feet embankment before coming to rest 400 feet further. A passenger was seriously injured while all other occupants escaped uninjured. The aircraft was written off.

The four engine aircraft was completing a flight from Brasília to Rio de Janeiro, carrying a delegation of the Brazilian government, among them Arturo da Costa e Silva, President of the Republic of Brazil. Upon landing at Santos Dumont Airport, the right main gear collapsed. The airplane sank on its belly and slid for several yards before coming to rest in flames. All 18 occupants escaped uninjured while the aircraft was considered as damaged beyond repair.

After touchdown at Raleigh-Durham Airport by night, the nosewheel collapsed. The airplane slid on the runway for several yards until it came to rest. All 43 occupants escaped uninjured while the aircraft was later considered as damaged beyond repair.

Before leaving Dublin no landing forecast for Lulsgate was available but the forecast conditions for Filton, 10 miles north of Lulsgate, were well above the company minima of 260 ft critical height and 800 rn RVR. About 25 minutes before commencing the approach to land and whilst the aircraft was on the airway near Strumble, the latest weather conditions for Lulsgate obtained by radio from air traffic control, showed that there was 3/8 cloud at 1 000 ft, visibility was 1 500 m with the sun tending to disperse cloud and mist. After leaving the airway, the aircraft was positioned by Lulsgate radar for an approach to runway 28 on a right-hand base leg. At 0752 hours GMT before the final approach was commenced, the latest weather conditions were passed by the Lulsgate rabar controller who was also the approach controller, these conditions showed a surface wind northerly 8 to 10 kt, QFE 979, QNH 1 001, visibility in mist 1 800 m. During the final turn on to the approach at 6 miles, the aircraft drifted to the left of the extended centre line which was regained closing from left to right during the final descent. At five miles from touchdown, still to the left of the centre line, a descent from 1 500 ft (QFE) was commenced at a rate of 300 ft per mile with advisory altitudes being passed every half mile. The air was calm and the commander was able to achieve a high degree of precision during the approach; heights were accurately flown during the descent and the aircraft's track, cow verging on the centre line, was steady, When the aircraft was between 3 and 34 miles from touchdown, the controller informed it that visibility had deteriorated to 1 200 m. At two miles, when steering 2950, the aircraft intercepted the approach centre line and its heading was corrected to 290°; at one and a half miles at 500 ft, a further heading correction was made on to 287°. A drift to the right, away from the centre line, became apparent when the aircraft was between 1 and 12 miles from touchdown and the controller gave further corrections to the left to 285° and 280°. At one mile from touchdown at 350 feet, a further left correction to 275° was given but the aircraft continued to track to the right of the centre line. At half a mile from touchdown, when the talk-down was complete, the controller informed the aircraft it was well to the right of the centre line and that it should overshoot if the runway was not in sight. Shortly afterwards the aircraft was seen, by a controller, heading towards the control tower before commencing its corrective turn to the left. The commander, who was at the controls of the aircraft, said it was possible to refer to the ground and natural horizon until passing through about 650 ft when a thin layer of cloud followed by misty conditions required the remainder of the approach to be made on instruments. Whilst descending through 300 ft, the commander asked the co-pilot if he could see anything but just as he replied in the negative the commander saw the approach lights ahead and to his left and he promptly commenced an 'St turn to line up with them. As he did so he called for 400 of flap and less power in order to reduce the airspeed from 130 kt to about 112 kt. During this phase, he lost contact with the lights "for some seconds" but he elected to continue the approach because the last reported visibility was 1 200 rn and he was confident the runway lights would shortly appear ahead. When they came into view the aircraft was over the left-hand side of the runway and not properly aligned with it; the commander said he attempted to turn on to the runway centre line as he flared out for the landing. During this manoeuvre, although he was not aware of it, the starboard wing tip and No. 4 propeller struck the runway; the aircraft then touched down on all its wheels with considerable port drift. The commander took overshoot action, applying full power, calling for 20° of flap and the undercarriage to be raised; the airspeed had, in the meanwhile, fallen below 100 kt. The commander realised that the aircraft was not accelerating normally and saw that it was headed towards buildings on the northern perimeter of the aerodrome; rather than risk flying into these obstructions, he flew the aircraft on to the ground with its undercarriagi retracting. The aircraft touched down starboard wing first, ground-looped tb the right as it slid along the remaining section of the adjacent runway, then crashed tail first through a fence. Ten of the occupants of the passenger cabin were injured, three of them seriously; fire did not break out; rescue and fire vehicles arrived promptly on the scene. The accident occurred at 0759 hours.

The Viscount had departed Dublin at 06:44 GMT for a pilot conversion training flight on an IFR flight plan. The instructor planned to spend 2 hours in a sector NW of Dublin, followed by practicing circuits and landings for one hour. Eyewitnesses reported seeing the aircraft entering a vertical dive from low altitude. The plane crashed and caught fire. All three crew members were killed.

The crew was involved in a local test flight out from Southend Airport in the goal to renew the Airworthiness certificate. Shortly after takeoff, while in initial climb, a technical failure occurred on the engine number four. The crew was forced to shut down the engine and to feather its propeller when control was lost. The airplane lost height and crashed in an open field located near the airport, broke in two and came to rest. While all three crew members were injured, two people on the ground were killed.

On 13th March 1967 Vickers Viscount aircraft ZS-CVA, "Rietbok", was on a scheduled public transport flight No. SA 406 from Port Elizabeth to Johannesburg via East London and Bloemfontein. Its Estimated Time of Arrival at East London was 1714 GMT, but the weather there was poor. The captain had indicated that he would probably overfly East London, but that he would have a look at conditions there before deciding to do so. The last communication from the aircraft was when it notified East London Airport Control that it was "at 2,000 ft. with the coastline in sight". It is estimated that the aircraft was then between 20 and 15 nautical miles from the Airport and that the time was approximately 1709 GMT. At 1710.08 GMT the aircraft crashed into the sea. The approximate position of the crash was 33°13.45’ S. , 27°38.3’ E. On board were Captain Gordon Benjamin Lipawsky, First Officer Brian Albert Richard Trenwith, 3 cabin crew and 20 passengers. Air-sea rescue operations were put in hand promptly, but there were no survivors. Bits of floating wreckage, consisting mainly of cabin interior fittings, were recovered by naval vessels and other pieces were washed ashore. The main wreckage of the aircraft is believed to he lying at a depth of between 180 and 220 feet, approximately 1½ miles off-shore. Extensive salvage operations were attempted, but were hindered by murky water, a current up to 8 kts and dangerous sea conditions. The aircraft was lost and all 25 occupants were killed.

Following a normal touchdown at Norfolk Municipal Airport, the crew started the braking procedure when the airplane collided with a snow plow. A wing was torn off and the snowplow was dragged over several meters. There were no injuries but the aircraft was damaged beyond repair.

The crew was completing a local training flight at Rio de Janeiro-Santos Dumont Airport. After touchdown, the four engine airplane was unable to stop within the remaining distance, overran and came to rest. All three crew members were unhurt while the aircraft was damaged beyond repair.
