Douglas DC-8

The aircraft was on a scheduled international flight from Buenos Aires to Rio de Janeiro (Galeao Airport) and Lisbon. It arrived at Galeao Airport following an uneventful flight. Another crew took over for the last segment of the flight. The takeoff run began at 2303 hours GMT from runway 14. The aircraft's acceleration appeared to be normal. The pilot-in-command declared that, at a speed between 100 and 135 kt (V1), he noted that the control column was too far back and pushed it forward. At this point the co-pilot released the controls, which is normally done when the aircraft reaches V1. It is believed that in fact an attempt to rotate the aircraft was made around 132 kt. The aircraft continued to accelerate normally. The co-pilot announced 148 kt, the rotation speed (VR), and the pilot pulled back on the control column. However, the aircraft did not respond, so he pushed it forward again. No indication of this rotation attempt was revealed by the flight recorder reading. He and the co-pilot then pulled back on the control column, however, the nose of the aircraft did not rotate since the pilot had already reduced power 14 seconds after reaching VR. Also, the tape reading indicated that the brakes were used for 5 seconds prior to any power reduction. The first marks of braking were found approximately 2300 m from the threshold. The pilot realized that the aircraft could not be stopped on the remaining portion of the runway so he turned the aircraft off the runway to the right and fully reduced power. The brakes were applied but not reverse thrust. Heavy and steady braking marks started 2600 m from the threshold. Of his own accord, the co-pilot applied full power for reversion and tried to operate the spoilers but could not do so because of the bumps The right wing lowered, dragging engines No. 3 and 4. The left wheels of the landing gear sank into the sand, and engines No. 1 and 2 also began to drag. All four engines lost their ejectors and reversion cones, causing the aircraft to accelerate. It continued moving at a high speed, hit the airport wall, crossed the adjoining highway, lost engines No. 1 and 2 and the left landing gear and finally came to rest in the sea. 50 m from shore. It drifted 100 m while floating and then sank to a depth of 8 m. There were no lights on board the aircraft when it came to a stop as the automatic emergency lighting system did not function. One cabin attendant used one of the two flashlights available. The darkness increased the panic and confusion. The passengers could not use the main door as an exit because it would open into the sea. They did not know where the emergency exits were. However, the exits were then opened and most of the passengers left the aircraft on the starboard side. The fact that the lour exits were all in the central part of the fuselage hampered the evacuation as the number of passengers (94) was considerable. The crew left the aircraft via the cockpit windows. No instructions had been given on emergency procedures and therefore the passengers and most of the crew did not take their life jackets with them when leaving the aircraft. Although the aircraft was equipped with six life rafts no crew member tried to use them. The aircraft drifted 330 feet downstream and submerged in 25 minutes. A crew member and 14 passengers were killed, 46 occupants were wounded and 44 were uninjured.

The crew was preparing to land at Bombay-Santa Cruz Airport runway 27 and was cleared to descend to 4,000 feet. After several errors, the pilot-in-command started the descent prematurely and while at an altitude of 3,600 feet, the airplane struck the slope of Mt Davandyachi (1,080 m high) located about eight km north of Junnar. The aircraft disintegrated on impact and all 94 occupants were killed. At the time of the accident, the airplane was off course by 9 km and its altitude was too low.

On July 11, 1961, at 1136 M.S.T., a United Air Lines DC-8 crashed during its landing roll at Stapleton Airfield, Denver, Colorado. None of the 122 occupants was severely injured as an immediate result of the impact; however, there were 16 passenger fatalities as a result of carbon monoxide poisoning when the aircraft burned. One other passenger, an elderly woman, broke both ankles during evacuation of the airplane and later succumbed to shock. In addition, the driver of a panel truck, which the aircraft struck after leaving the runway, also suffered fatal injuries. After experiencing hydraulic difficulties following takeoff from Omaha, Nebraska, the crew of N8040U continued the flight to Denver, using procedures set forth in the flight manual for abnormal hydraulic situations. When the flight arrived in the Denver area, preparations were made for landing. The ejectors were extended hydraulically, however, when an attempt was made to extend flaps to 25 degrees the hydraulic pressure dropped to zero. The hydraulic system selector was then placed in the No. 3 position (flap and gear downlock), and the approach was continued. After touchdown, the throttles were placed in the idle reverse thrust position and when power was applied, an uncontrollable deviation from the runway occurred.

VIASA Flight 897 operated on the route Rome - Madrid (MAD) - Lisbon (LIS) - Santa Maria (SMA) - Caracas (CCS) when it landed at Lisbon at 00:06 UTC. Following a crew change and inspection by KLM maintenance personnel the flight was cleared for a runway 23 departure. The DC-8 took off at 01:15, heading the Capiraca (LS) NDB. At 01:18:37 the aircraft advised that the cloud base was at 3700 ft and changed to the Lisbon area control frequency. It reported again at 01:19 :25 to Lisbon Control that it was "over LS at 19 climbing through FL 60". This message ended with two quickly spoken sentences. This was the last radio contact with the flight. The DC-8 entered a spiral dive to the left during the last message, banking to the left to 90° within about 20 seconds and striking the water after another 15 seconds . During the last 15 seconds, the bank was over-corrected to the right. It struck the sea with a pitch angle of approximately 25° nose down, while it was probably banking 30° to the right.

The first approximate 6,200 feet of takeoff roll was observed by control tower personnel, visually, until the aircraft was lost to view by obscuring snow, approximately 3,800 feet from the control tower. They stated that at that time the aircraft had not taken off or rotated. Another tower controller observed the aircraft by airport surface-detection *** radar from the start of its roll to the eastern end of runway 7R, where it disappeared from view. A few seconds later he observed a bright orange flash on the sky northeast of the airport. He could not tell if the aircraft left the runway. Emergency procedures were started immediately by the controllers and an unsuccessful attempt was made to contact the flight on the departure radio frequency. Captain Poe was the only survivor of the four cockpit occupants. He stated as follows: The checklist was accomplished normally. The runway condition was good and everything apparently occurred in a routine manner through the 100-knot time check when the first officer called out "***" (Spanish for 100). Upon reaching approximately 130 knots (the V1 speed) the first officer called out V1 and VR rapid succession. The aircraft was then rotated quickly and somewhat excessively. Poe did not see the airspeed go over 130 knots and as rotation started he saw the airspeed start to drop back quite rapidly to about 110 knots. At this time the Aeronaves captain called or pointed to the airspeed indicator. Poe felt that the aircraft could not become airborne under these conditions and that the runway remaining was not long enough to put the nose back down to start the takeoff again from that speed. His only choice, so he stated, was to try to get the aircraft stopped on the runway. Poe unfastened his safety belt, stood to gauge progress down the runway, moved forward, shoved the throttles forward briefly, noted a normal and uniform response from the engine instruments (the EPR gauges were reading normally from 2.52 to 2.54), and then pulled the throttles full back. Captain Gonzales "immediately" pulled the reverse throttles back into reverse thrust and used wheel brakes. Poe extended the spoilers and then sat down on the jump seat without refastening his seat belt. He believes that the aircraft did not take off Whether it did or not wall be discussed later in this report. Poe's actions would have taken about three seconds, an shown by later test. The aircraft continued ahead the full length of the 10,000-foot runway, beyond it, through a blast fence, 3 catching on fire, through the airport boundary fence, and across Rockaway Boulevard where it struck an automobile injuring the driver and sole occupant. After going through the blast fence, many parts were shed before the aircraft came to rest in flames 830 feet beyond the end of the runway. Emergency vehicles from the airport and of the New York Fire Department were quickly started for the scene. Although impeded somewhat by weather conditions, they reached it within about six minutes and extinguished the fire. Evacuation and rescue of the occupants had already been effected in a total time of about five minutes, although most persons were out of the wreckage and away from the fire site in half this time. Many of the survivors were taken to hospital in privately owned vehicles. Destruction of the aircraft was extensive.

On December 16, 1960, at 1033 e.s.t., a collision between Trans World Airlines Model 1049A Constellation, N 6907C, and a United Air Lines DC-8, N 8013U, occurred near Miller Army Air Field, Staten Island, New York. Trans World Airlines Flight 266 originated at Dayton, Ohio. The destination was LaGuardia Airport, New York, with one en route stop at Columbus, Ohio United Air Lines Flight 826 was a non-stop service originating at O'Hare Airport, Chicago, Illinois, with its destination New York International Airport, New York. Both aircraft were operating under Instrument Flight Rules. Following the collision the Constellation fell on Miller Army Field, and the DC-8 continued in a northeasterly direction, crashing into Sterling place near Seventh Avenue in Brooklyn, New York. Both aircraft were totally destroyed. All 128 occupants of both aircraft and 6 persons on the ground in Brooklyn were fatally injured. There was considerable damage to property in the area of the ground impact of the DC-8. TWA Flight 266 departed Port Columbus Airport at 0900, operating routinely under Air Traffic Control into the New York area The New York Air Route Traffic Control Center (ARTCC) subsequently advised that radar contact had been established and cleared the flight to the Linden. Intersection, Control of the flight was subsequently transferred to LaGuardia Approach Control. When the flight was about over the Linden Intersection, LaGuardia Approach Control began vectoring TWA 266 by radar to the final approach course for a landing on runway 4 at LaGuardia. Shortly thereafter TWA 266 was cleared to descend to 5,000 feet, and was twice advised of traffic in the vicinity on a northeasterly heading. Following the transmission of this information the radar targets appeared to merge on the LaGuardia Approach Control radar scope, and communications with TWA 266 were lost.United Air Lines Flight 826 operated routinely between Chicago and the New York area, contacting the New York ARTCC at 1012 Shortly thereafter the New York Center cleared UAL 826 to proceed from the Allentown, Pa., very high frequency omni directional radio range station (VOR) direct to the Robbinsville, New Jersey, VOR, and thence to the Preston Intersection via Victor Airway 123. At approximately 1021, UAL 826 contacted Aeronautical Radio, Inc. (ARINC) to advise their company that the No. 2 receiver accessory unit was inoperative, which would indicate that one of the aircraft's two VHF radio navigational receivers was not functioning. A "fix" is established by the intersection of two radials from two separate radio range stations. With one unit inoperative the cross-bearings necessary can be taken by tuning the remaining receiver from one station to the other. This process consumes considerable time, however, and is not as accurate as the simultaneous display of information on two separate position deviation indicators While UAL 826 advised the company that one unit was inoperative, Air Traffic Control was not advised. At 1025 the New York ARTCC issued a clearance for a new routing which shortened the distance to Preston by approximately 11 miles. As a result, this reduced the amount of time available to the crew to retune the single radio receiver to either the Colt' s Neck, New Jersey, or Solberg, New Jersey, VOR in order to establish the cross-bearing with Victor 123, which would identify the Preston Intersection. In the event the crew would not attempt to retune the single VOR receiver, crossbearings on the Scotland Low Frequency Radiobeacon could be taken with the aircraft direction finding (ADF) equipment. This would be a means of identifying the Preston Intersection but, under the circumstances, would require rapid mental calculation in the interpretation of a display which could be easily misread. Several factors support the conclusion that this occurred. Instructions had been issued to UAL 826 for holding at the Preston Intersection the clearance limit, should holding be necessary. Clearance beyond Preston for an approach to Idlewild Airport would be received from Idlewild Approach Control and the transfer of control of the flight from the New York Center to Idlewild Approach Control would normally take place as the aircraft was approaching Preston. UAL 826 was not receiving radar vectors, but was providing its own navigation. After the flight reported passing through 6,000 feet the New York Center advised that radar service was terminated and instructed the flight to contact Idlewild Approach Control. UAL 826 then called Idlewild Approach Control, stating "United 826 approaching Preston at 5,000." This was the last known transmission from UAL 826. At the time UAL 826 advised it was approaching Preston it had in fact gone on by this clearance limit several seconds before and was several miles past the point at which it should have turned into the holding pattern. This is confirmed by the data obtained from the flight recorder which had been installed in the UAL DC-8, as well as by analysis of the communication tapes At a point approximately 11 miles past the Preston Intersection a collision occurred between TWA 266 and UAL 826. Weather at the altitude of the collision and at the time of the accident was such as to preclude flight by visual means.
