The cleverness of investigations done without access to the black boxes always astounds me. The East coast Jets 81 crash from 2008 only had a cockpit voice recorder, no flight data recorder, and so the investigation had to focus entirely on analyzing the wreckage, eyewitnesses and the recording. The recording is available on KZbin, it's horrible to listen to though. I think it would make for an interesting video regardless. It's basically a lesson about how fatigue alone can bring down a perfectly good plane.

Thank you for researching this. Rather ironically, this is one of the few major air crashes of which I was not aware. At the date of its occurrence I was in my first few days of the training that would eventually lead to my career as an aircraft mechanic. Not only was I busy with my studies, there was no television available in the dorm where I stayed, so I did not hear of the accident. The DC-8 is one airplane with which I had zero experience in the following years, but I have seen a similar problem on the early 737 airplanes that did not lead to such serious consequences. Once again it was a pitch trim problem. On the 737, a mach trim actuator was installed to follow commands from a mach trim computer and change the relationship between the elevator position and the horizontal stabilizer at high speeds. If this actuator failed in the high speed position, either the autopilot or flight crew would trim the horizontal stabilizer for pitch control as the airplane slowed down. No problem so far. But upon landing, as the pilot pulled the column back to flare the airplane for touchdown, the mis-trimmed stabilizer would limit the force the elevator could exert to raise the nose, and it became a near thing to get the airplane on the ground safely. No accidents resulted, but there were some unsettling moments before the problem was resolved.

Eastern Airlines was my favorite airline as a child because it always brought my wonderful grandparents down from NY for the holidays for a 3 month stay and I always looked forward to it. My grandparents would always get the plastic Easter airlines pin typically given to children who flew the airlines and to be worn on the shirt. Eastern Airlines brings back so many wonderful memories for me.

Eastern Airlines was a mess. There was a conspiracy with a crash in jan of 1985 (eastern air Flight 980) where it went down in the mountains of Bolivia. The GOVT said the site was inaccessible and there would be no way to reach it. BUT 3 men were able to walk up to the site at 19,600 ft. They said there were no bodies or Blood and the FDR and CVR were nowhere to be found. They noted that there were a large amount (over $1million) in poached reptile skins in the cargo. THEN 7 months later In August 1985, the Federal Aviation Administration fined Eastern nearly $1.4 million after more than 1,700 pounds of cocaine valued at $430 million was found aboard two jets flying into Miami from Colombia. Baggage handlers in Colombia put cocaine-filled suitcases in bags on jetliners bound for Miami and the luggage was unloaded after passenger bags were removed. The nation’s largest cocaine-trafficking pipeline has been cut with the indictment of 23 airline employees. $1 billion in Colombian cocaine is believed to have moved through Miami International Airport during the past four years with the help of 22 Eastern Airlines employees and one Mexicana Airlines worker.

I worked as a marine electrician during the early 1980's. I spent some time working on the shell-dredges that harvested the small, white shells from the bottom of Lake Ponchatrain. These shells were quite popular for driveways all throughout the south. A dredge arm dug out the bottom of the lake, washed the silt out of them on a big wash-board type of equipment with lake water, and conveyed the washed shells to a barge tied alongside of the dredge. Lake Ponchatrain is near the New Orleans airport (now called Louis Armstrong Airport), and the military used to launch many, many training flights over the lake. General aviation also flew over the lake with private airplanes. They still do. The dredge would often dredge right through the wreckage of crashed airplanes as it dug out the shells. The remains of some of these aircraft would slide up the angled dredge-head, fall off as they breached the surface, then disappear again into the murky lake-water. I asked the Captain if they ever reported it, and he said, "Nobody wants to know about it". They probably dredged right though the remains of flight 304, more than likely several times. The dredges no longer operate in this lake, and the water has returned to a more natural state that supports a healthy water environment.

Maybe the dredging company and the one who contracted them didn't want the hassle of halting for a long indefinite time... I know here on island, if construction finds bones or a burial ground, they must stop and advise the appropriate gov't dept. Then, they have to wait for the archeological team to painstakingly dig out the remains and ensure no other historical remnants in that vicinity. It can take months. With construction deadlines, it will cost everyone involved loss of money.

The missing bushing saved them. Didn't American Airlines ever do PMs and inspections of the planes? It seems to me that a routine check would have found the missing bushing. The automatic Pitch Control problem should have been looked into immediately. It proves that air crashes are a string of events that combine to make these things happen.

@@tonyperone3242 Of course they do inspections on the aircraft. There are multiple inspections done on aircraft, starting with simple thru flight inspection all way up to phase and depot inspections. You can inspect every last hydraulic or electrical driven actuator on the aircraft and never know that a bushing is incorrectly installed. For components that effect safety of flight, there are often what is called an in process inspection (IPI) required when installing such a component. This is required because once the installation is complete, it is impossible to tell if the critical portion of the installation was done correctly. As far as items that may fail from wear or corrosion, those are always on a time change or time inspection schedule.

A bushing can be stainless steel, aluminum, or hard plastic. To have a bad mount on any control surfaces on an aircraft, it would be like having a steering rack on a car with loose bolts. The autopilot would command control surfaces, when the mounts move around, the surfaces don't respond properly, that would disable autopilot. You're right, it's a little the messed up mount, a little on the turbulence.

I know it's an old thread, BUT bushings can be found all over the place. For those who have never seen them before, maybe I can help... The very simplest of them are basically a combination spacer/stabilizer-sleeve. They can be cup-shaped or more like a top-hat, and can be made of just about anything. The choice of material depends mostly on the relative purpose and levels of abuse they're supposed to endure for the life of a given machine or appliance. I frequently rebuild and restore equipment and tools, so I run into them most often around the shafts of electric motors and in gear-boxes to align the moving parts. Angle grinders while have them to hold the drive-gears together, a cupped bushing in the "head" for the receiving gear, and the top-hat "sleeve" for the shaft of the motor to align the pinion/driving gear so the teeth perfectly mesh with the other... In a blender, there's a sleeve-type (frequently top-hat shaped) right above the motor to align the shaft that drives the blades around in the bottom of the pitcher... AND of course, fans will have the sleeve between the motor and the blades, and some have a cup at the back-side of the motor to keep the shaft straight and quieter within the housing. On heavier machines like motorcycles, bearings are frequently employed to smooth out and reduce friction around the axles, while the bushings are more of a "sacrificial" role made of bras, aluminum, or bronze so they get worn down to protect the frame and the housing of the bearing race. It's a REALLY useful little piece for a lot of different but very similar applications. Most of the time, however, they make a rebuild cheaper because it's easier to afford replacing a little sleeve or cup of copper/brass/bronze/aluminum/plastic/etc... than it would be to weld in a build up of metal housing and then re-tool the shape of the bearing(s) or the shaft that carries torque through the opening... ;o)

They did not ground the airplane - manly because the people in charge of deciding on grounding had much more knowledge of aircraft systems and engineering than Surfer Dude. The PTC system of the DC-8 can not be compared with the MCAS of the Boeing 737MAX. It was a well designed system that was active only in high speed cruise flight. It also had nothing to do with the main pitch trim system (Stabilizer Trim via jackscrew) This DC-8 did NOT crash due to a bad design of a system. It crashed due to a mechanical problem in the jacksrew system which was caused by a previous maintenance error.

The DC-8 was a brilliant airplane in many ways, but woefully under-engineered in many others. Unlike Boeing which waited to start full production until after the prototype “dash 80” was tortured every conceivable way during certification and pre-production testing, Douglas didn’t have the luxury of time. They were so convinced jets weren’t really viable and that the new piston powered DC-7 was the next big thing, they futzed around until they were two full years behind Boeing in the development process for their first jet. As a result Douglas decided not to build a bespoke prototype for testing and instead would use the first production aircraft to come off the line for type certification and “real world” torture testing. That means an awful lot of problems (some known, others yet undiscovered) were neither revealed during the abbreviated testing nor fixed on the subsequent aircraft already in production. Douglas took a huge gamble delivering aircraft that still had a lot of secrets yet to be revealed. This particular vulnerability is one of many unwelcome surprises that the DC-8 would spring on unsuspecting pilots during those first few years.

I could feel the minor muscle tremors in my arms in the movement of the aircraft. It took about a second for an unintentional twitch to show up as a slight roll or pitch change, and those movements were on the order of a mm or so.

A bushing is really just what you described. It's a chunk of rubber or polyurethane (a very soft plastic) which separates metal or load bearing components that have to move. The suspension components in your car use a load of bushings to this effect. An example would be a stabilizer bar (aka anti-roll bar) link pin, which is basically a metal linkage with nuts at both ends that connect to stuff. You'd have the nut holding the bar there, a washer for the bushing to seat against, the bushing, the metal component the link pin attaches to, and another bushing with a welded washer in place. I hope this makes even a lick of sense. Bushings are usually incorporated into designs where metal parts meet, but have to move. The bushing allows those metal components to move around relative to each other, without wearing out those metal parts. If you install bushings upside down, it absolutely will chew the bushing out because the metal fixing basically eats it alive. Again, hope it makes sense.

The natural reaction of a pilot with the airplane pitching down and the airspeed increasing is to pull the power off and pull back on the elevator. There was a case where EAL had an airplane pitching down, over speeding and the pilot did the opposite. He pushed the power up, and recovered. In any airplane without fly by wire and engines mounted under the wing if you add power the airplane will pitch up and probably the only way to recover from a high speed nose down incident.

Regarding the bushing upside down in the stabilizer jackscrew unit, how is that possible normally the bushing will have a case or cover to keep it in place, if the the screw only can travel one way then the bushing also has groves to keep it from moving, if the bushing travel with the screw up and down then the bushing will have lips on both side then there is no such a thing is upside down.

Thanks for shedding light on a lesser known crash. It is very interesting at this time due to the similarities to the 737 Max and MCAS crashes. Air transport safely is the most important factor that a manufacturer must consider when designing and manufacturing aircraft. The human factor makes this tricky but the more pilots are told about how their plane flies and responds due to the airframe itself and the various flight control systems the safer flying can be because of pilots not being surprised by what the plane is doing. I have not been able to find out how much Douglas knew about this issue so it is hard to make a good judgment on how responsible the company was but the similarities to the Max are striking.

Marc McReynolds hello it’s odd you mention ‘thrust REVERSERS’ in flight , on the BC8, the THRUST REVERSER LEVER IS VERY CLOSE TO LANDING GEAR LEVER , I believe it may have been in 70s/80s AIR CANADA was to land at LESTER PEARSON , TORONTO so while getting ready in the patern, they DEPLOYED THRUST REVERS so it JUST FELL OUT OF THE SKY, , I believe the fix Was to PAINT THE LEVERS DIFFERENT COLOURS Cheers 🇨🇦🇺🇸

@@flybyairplane3528 That sounds a lot like Air Canada 621, where the spoilers of the DC-8 deployed at sixty feet on approach (deviation from approved procedure regarding spoiler arming had the pilots miscommunicating). The aircraft touched down hard enough to cause wing/engine damage, then during the ensuing go-around (bad decision #2) a series of fires and deflagrations destroyed one of the wings before they could return to the airport.

@@markprange4386 Thank you for clarifying my vague statement "the spoilers of the DC-8 deployed". In deviating from procedure, a callout at 60 feet to arm the spoilers was taken by the FO as a command to deploy them. I can only imagine that the FO's mind was momentarily elsewhere at that critical moment, since deploying spoilers at that altitude would make no sense whether commanded or not. > I believe the fix Was to PAINT THE LEVERS DIFFERENT COLOURS < There's a quasi-joke in the airframe business that if you can't fix the problem, "placard it" (the equivalent joke in the railroad industry is that if a part breaks, "double the dimensions and paint it black").

I would like to know more about why the dc-8 could not be raised from the bottom of the lake. also, if there was s problem and the airline knew about it, why wasn't the dc-8 taken out of service and allowed to fly with passengers? They were going to fix it in Nee York....but that was too late and they ran into severe turbulence that made things worse. If an airliner has anything wrong with it, it should be taken out of service and repaired correctly....money should never be placed over human lives

DC-8 is an old jet, it hitting MACH 1 would be disastrous, it would never survive to get anywhere near 'high mach'. I'd need to see the 'prints, but support bushings are typically exactly that, a bushing of sacrificial material designed to keep a rotating part in alignment. If it was installed upside down, then it is possible that sufficient throw on the jackscrew was able to knock it out of place.

@@aeomaster32 It couldn't 'fly' at over Mach 1 though. The example you mention was a risky one off and was achieved by a sharp dive from 52,000 feet (a very impressive feat in its self). It exceeded the speed of sound for 16 seconds at 1% over. While a DC-8 did achieve this the top speed was 'only' a still very impressive near 590mph but significantly short of Mach 1 without inducing it artificially. Sadly, it was scrapped after two decades of service (so I read) and personally I think it should have been preserved. A great shame.

Eastern experienced quite a few crashes during its long run, some stranger then others? Eastern Air Lines Flight 21 - A Douglas DC-3 crashes while descending to land at Atlanta, Georgia. Eight out of the 16 on board were killed. Eastern Air Lines Flight 45 - A Douglas DC-3A collides with a Douglas A-26 Invader over Florence, South Carolina, US. One of the 24 on the DC-3 and two of the three on the DC-3A die. Eastern Air Lines Flight 66 - A Boeing 727 encounters wind shear on final approach, strikes approach lights at JFK International Airport and crashes, leaving 113 out of the 124 people on board dead. Eastern Air Lines Flight 212 - A McDonnell Douglas DC-9 crashes on approach into Charlotte, NC. The DC-9 experiences a controlled flight into terrain due to pilot error. 72 out of the 82 on board were killed, including famed political satire Stephen Colbert's father and his two brothers. Eastern Air Lines Flight 304 A Douglas DC-8 flying between New Orleans International Airport to Washington National crashes into Lake Pontchartrain, killing all 51 passengers and seven crew on board. Eastern Air Lines Flight 375 - A Lockheed L-188 Super Electra crashes on its takeoff roll from Boston Logan International Airport. The Electra is seen crashing into Winthrop Bay, after multiple bird strikes. 62 out of the 72 onboard perish. Eastern Air Lines Flight 401 - A Lockheed L-1011 TriStar crashes in the Florida Everglades. The crew onboard is distracted by a faulty gear-down light, resulting in a controlled flight into terrain. 101 out of the 176 people on board are killed. Eastern Air Lines Flight 512 - A Douglas DC-7B crashes due to pilot error during a missed approach go-around at Idlewild Airport, New York. 25 out of the 51 onboard are killed. Eastern Air Lines Flight 537 - A Douglas DC-4 on approach for Washington National Airport collides with a Lockheed P-38. All 55 people on board are killed. The pilot of the P-38 is seriously injured. Eastern Air Lines Flight 605 - A Douglas DC-4 loses control and crashes near the town of Bainbridge, Maryland, US. All 53 passengers and crew on board are killed, making it the deadliest crash in US history at the time. Eastern Air Lines Flight 663 - A Douglas DC-7B on its takeoff roll overreacts in avoiding Pan Am Flight 212 (A Boeing 707) which is on approach. The DC-7B crashes and loses control. The Douglas DC-7B crashes into the ocean near Jones Beach State Park, NY. All 84 onboard perish. Eastern Air Lines Flight 665 - A Douglas C-49 crashes into high ground near Galax, VA, the US after the pilot experienced spatial disorientation. Only one out of the 19 onboard survive. Eastern Air Lines Flight 853 - A Lockheed Super Constellation collides with a TWA Boeing 707 performing TWA Flight 42. TWA Flight 42 makes an emergency landing at JFK International Airport, while Eastern Air Lines Flight 853 crash lands on Hunt Mountain near Danbury, Connecticut, US. Three passengers and one pilot perish. No casualties were reported on the TWA Boeing 707. This is also known as the 1965 Carmel mid-air collision. Eastern Air Lines Flight 855 - A Lockheed L-1011 TriStar loses power from all of its three engines due to faulty maintenance. The flight crew succeeds in restarting the #2 engine on the third attempt and safely lands at Miami International Airport. Eastern Air Lines Flight 980 - A Boeing 727 owned and operated by Eastern Air Lines impacts Mount Illimani, Bolivia. All 29 onboard are killed. Eastern Air Lines Shuttle Flight 1320 - A Douglas DC-9-31 on a flight between Newark, NJ and Boston, MA is hijacked by a suicidal man. He shoots the captain and co-pilot before being subdued. The captain makes a successful emergency landing at Boston Logan International Airport and the hijacker is arrested. The co-pilot dies from his injuries.
