RFT 551: Continental Flight 603

Description
The aircraft involved in the accident was a McDonnell Douglas DC-10-10, registered N68045, which had made its first flight in 1972. The captain was 59-year-old Charles E. Hersche, who was operating his last flight before retirement. He had been with Continental Airlines since 1946 and had logged 29,000 flight hours, including 2,911 hours on the DC-10. Hersche served with the U.S. Air Force from 1942 through 1953 during World War II and Korean War. The first officer was 40-year-old Michael J. Provan, who had been with Continental Airlines since 1966 and had 10,000 flight hours, with 1,149 of them on the DC-10. The flight engineer was 39-year-old John K. Olsen, who had been with the airline since 1968. He was the least experienced member of the crew with 8,000 flight hours, 1,520 of them on the DC-10. The aircraft began its take-off from Los Angeles International Airport at around 9:25 am. During the takeoff roll, the recapping tread of the number-two tire on the left main landing gear separated from the tire and the resulting overload caused that tire to blow out. That, in turn, imposed an overload on the number-one tire on the same axle, resulting in a second blowout almost immediately after the first blowout. Pieces of metal from the rims of the failed tires then damaged the number-five tire on the left main gear, causing it to also blow out. Although Captain Hershe initiated the abort procedure at 4 knots (7.4 km/h; 4.6 mph) below V1 speed, it became apparent the aircraft could not stop within the confines of the runway. This was the direct result of the partial loss of braking power following the failure of the three tires on the left main gear, and also because the runway was wet. The captain steered the aircraft to go off the end of the right half of the runway in an effort "to go beside the stanchions holding the runway lights", thus avoiding a collision with the approach light stanchions, which were positioned immediately beyond the end of the runway.  About 100 feet (30 m) beyond the end of the runway, the left main gear broke through the nonload-bearing pavement, which caused it to collapse rearward. Portions of the failed gear punctured fuel tanks in the left wing, immediately starting a fuel fire on the left side. The aircraft slid to a stop about 664 feet (202 m) beyond the departure end of the runway. Because of the fire on the left side of the aircraft, all passengers evacuated on the right side. All four emergency evacuation slides on the right side of the aircraft were affected by the heat and failed at some point during the evacuation.  Flight 603's flight crew and an off-duty pilot worked quickly to guide passengers to alternate exits as the slides failed, actions later commended by the National Transportation Safety Board (NTSB) for saving lives and reducing the number of injuries.[1]: 38  Passengers who were still on board after the last slide failed were forced to either jump to the ground, or use a slide rope deployed from the first officer's cockpit window. Of the 186 passengers and 14 crew on board, two passengers died due to burning and smoke inhalation. Moreover, 28 passengers and three crew members were seriously injured during the evacuation. Two of the seriously injured passengers died as a result of their injuries about three months later. A large portion of the aircraft's left section was destroyed. The aircraft subsequently was written off as a hull loss. The accident represents the second fatal accident and fifth hull loss of a McDonnell Douglas DC-10. During its investigation, the NTSB found the number-two tire failed because it threw off its (recapped) tread. The number-one tire then failed because it was overloaded and had fatigue in its ply structure. The number-five tire then failed, because it was hit with a piece or pieces of metal from either the number-two or -one wheel. The failure of that third tire on the left main gear probably contributed t
