who thinks the DC 10 is the plane with the worst history
Shouldnt he DC 10 earn the title as "screaming metal death trap with wings"
[edit] Incidents and accidents The early DC-10s suffered a trying time during the 1970s when a string of notorious incidents and crashes led to a brief grounding by the United States Federal Aviation Administration. [edit] Cargo door problem The outward-opening cargo door design problem was first identified on June 12, 1972, when American Airlines Flight 96 lost its aft cargo door after takeoff from Detroit, Michigan, but the crew was able to perform an emergency landing with no further incident. Before Flight 96 took off, an airport employee had forced the door shut, weakening the locking pin and causing the door to blow out as the plane reached altitude. Although many carriers voluntarily modified the cargo doors and re-trained their ground crews, there was not yet a mandatory redesign of the system. Severe design problems still persisted with the aircraft's cargo doors, and two years after the American Airlines incident, an almost identical cargo door blow-out caused Turkish Airlines Flight 981 to crash into a forest near the town of Ermenonville shortly after leaving Orly Airport in Paris on March 3, 1974. 346 people were killed in one of the deadliest air crashes of the twentieth century, recorded in Aviation History books as the "Ermenonville air disaster". The circumstances surrounding this crash were similar to those surrounding the previous accident; however, a modified seating configuration on the Turkish aircraft exacerbated the effects of decompression which caused the floor of the aircraft to collapse into the cargo bay. Vents were not present to allow the pressure between the cargo and passenger compartments to equalize. Control cables running through the floor of the plane were severed when the floor collapsed and this rendered the aircraft uncontrollable. In the aftermath of this crash, all DC-10s underwent a mandatory door redesign. [edit] American Airlines Flight 191 In 1979, with the cargo door issues resolved, DC-10s (all series) around the world were grounded following the crash of American Airlines Flight 191. Flight 191 lost its number one wing engine after taking off from O'Hare International Airport in Chicago, USA, May 25, 1979.[1] As the engine separated upwards, it ripped through the leading edge of the wing, rupturing hydraulic lines which caused a hydraulic cylinder that locked the port wing slats to fail. As airspeed was reduced per AA emergency climb-out procedures, the slats retracted, the left wing stalled, the plane rolled left and crashed before the flight crew could recover. All 271 people on board, plus two on the ground, were killed in this accident; the worst single plane crash in America. The United States National Transportation Safety Board (NTSB) officials discovered that a maintenance procedure was the culprit: American Airlines mechanics had removed the engine and its pylon together, rather than removing the engine from the pylon then the pylon from the wing, as recommended by McDonnell Douglas. This was done using a forklift and the pylon was inadvertently cracked in the process. The short-cut procedure, thought to save several man hours on maintenance, was used by three major airlines, although McDonnell Douglas advised against it.[7] Although McDonnell Douglas was not directly at fault for the pylon separation, it redesigned the DC-10 to allow more redundancies in the hydraulic systems. The Chicago incident also highlighted a major deficiency in the DC-10 design—its lack of locking flap mechanisms designed to maintain their position in the event of a hydraulic or pneumatic failure. Other wide-body aircraft of the day carried such a feature, but it was omitted from the DC-10. Another deficiency highlighted in the NTSB report was the vulnerable placement of wiring at the leading edge (front) of the wing. When the engine pulled up and over the wing, it tore out these wires, thus rendering inoperable vital warning instruments in the cockpit. Other aircraft of this era typically placed this kind of wiring in the center of the wing, in a less vulnerable position. In addition, only the pilot had a stick-shaker to warn of stalling, as the co-pilot was the one flying the plane, there was no warning that the plane was stalling. [edit] United Airlines Flight 232 Another instance of a DC-10 crash was the Flight 232 disaster at Sioux City, Iowa, USA, on July 19, 1989. After the #2 engine (tail engine) suffered an uncontained fan disk failure in flight which ruptured critical hydraulic lines, the crew, led by Captain Al Haynes and assisted by a senior pilot flying as a passenger (Dennis E. "Denny" Fitch), performed an emergency landing by varying remaining engine power to control the plane. Although the aircraft was destroyed with the loss of many lives, the crew flew the aircraft onto the runway in a partially controlled manner and 185 of the 296 people on board survived. The Sioux City crash concerned investigators because the total loss of hydraulic pressure aboard the DC-10 was considered nearly impossible. The design had lines from all three independent and redundant hydraulic systems in close proximity, directly beneath the #2 (tail) engine. Debris from the #2 fan disk separation failure penetrated all three lines resulting in total loss of control to the elevators, ailerons and rudder. [edit] Other notable accidents and incidents Other than the American Airlines, Turkish Airlines and United Airlines crashes well covered by the media and mentioned above, many other DC-10s were lost in different types of accidents. Other notable incidents involved DC-10s.

Re: who thinks the DC 10 is the plane with the worst history
there is a great saying....s### happens.
planes crash, there is no avoiding that, and the dc-10 is a good plane. if you want death traps, why not look at single engine GA aircraft? much more prone to crashing than any airliner. not that that is stopping me from flying them.......

you just compiled some wiki info. ![]() i've talked with some old pilots and they even think the DC-10 during its time was somewhat 'better' than the MD-11, which at some point was called the 'deathstar' or 'widowmaker.' and i'm going to bet there are far more 737 and/ or A320 incidents just because of the sheer number of units around for the past so many decades. you should have presented a better argument than a mere compilation of wiki info. you don't come to conclusions by linking random web info. give us raw data, graphs and comparisons.

Re: who thinks the DC 10 is the plane with the worst history
i was thinking about that as well
i watched air crash investigations and they had bacl to back episodes regarding 3 dc 10 crashes... although 1 of it isnt because of the manufacturer but because of the poor maintenance... |

Re: who thinks the DC 10 is the plane with the worst history
How about a thread title and subject change?
Who thinks bismarkintlairport is the worst poster in wings900 history? I like it! I think others like it too

Re: who thinks the DC 10 is the plane with the worst history
Did you read some of the descriptions,
September 19, 1989 – UTA Flight 772, DC-10-30 N54629, crashed in Ténéré Desert following an in-flight bomb explosion, claiming the lives of all on board. November 28, 1979 - An Air New Zealand DC-10-30 flew into Mount Erebus in Antarctica during a sight-seeing trip. All 257 on board Air New Zealand Flight 901 were killed. The accident was caused by complex factors not related to the airworthiness of the aircraft. February 2, 1981 – Pakistan International Airlines DC-10-30 AP-AXE was destroyed in a hangar fire at Karachi, Pakistan. There were quite a few "Overruns" as well. I'm with ya Dylan, RapleylikeBa and Southwest freak are also high on my list for worst poster/ annoying.

Re: who thinks the DC 10 is the plane with the worst history
I wouldn't believe everything that wikipedia has to say. The DC-10 was a good plane. Of course this thread being posted by someone who wasn't alive for the majority of these incidents. I am with Dylan on this one

Re: who thinks the DC 10 is the plane with the worst history
Who can say this guy is a complete moron?! I mean c'mon man this airplane is still in service after many DECADES and I can't remember anyone else saying anything like this.

Re: who thinks the DC 10 is the plane with the worst history
I dont know how anyone could make the claim that one aircraft or another is the worst in the history of aviation. Furthermore relying on wiki data alone to prove such a point is by far one of the worst methods of conducting that kind of research.
The DC-10s problem was that on early models, dougles engineers decided to put Primary, auxiliary, and second auxiliary hydrolic lines next to and parallel to one another along the flight surfices of the aircraft, such as the wing, vertical and horizontal stabilizers. This was the fatal mistake of the aircraft, since if something where to puncture one line, it would most likely puncture all three at once. This design defect was alleviated on later models spacing out the hydrolic lines several feet apart. Secondly, the DC-10 was a difficult aircraft to maintain, dougles experemented with new technologies and methods which wherent easy to understand, futhermore the early manuals where quite poor and not very explicit on detail. The third problem of the DC-10 was not the aicrafts fault, instead the mechanics, who when performing maintenance on the engine, would detach the engine and the pilon simultaniously, causing damage to the attachment points between pilon and engine. This was a common practice at the time, mechanics didnt know they where doing damage to the engine due to its complicated design. Inflight, vibrations would cause additional damage to these attactchment points weakening them further, this is responsible for the accidents in which one of the wing mounted engines would fall off, which happend two or three times i think, this would cause the engine to fly off over the wing, severing all three hydrolic lines, which as i stated above where right next to each other. Though these problems where discovered and fixed the DC-10 kept its negative reputation, which never really went away. It had its problems, but making a claim that it is the worst aircraft in history? Absurd. This aircraft dispite its flaws still became a successfull aicraft, selling over 385 models, plus KC-10 variants. The MD-11 was built on its success, and many examples of this type are still in service, as stated by above posters. |

Re: who thinks the DC 10 is the plane with the worst history
To build on what has been stated,kindly explain what:"Landing on a closed runway,Engine/Pylon change with a forklift,and flying into a mountain have to do with the aircraft itself? I believe the press hurt the DC-10 more than anything. If you are old enough to remember the late 70's,the press basically suggested that you make out a will before you fly on the DC-10. How stupid.
