This is the story of the 2021 crash of the 987 investments Md87 crash. On the 19th of October 2021 an MD87 owned by 987 investments LLC. this was a private charter flight meant to take a few people all the way from houston executive airport to boston to watch the houston astros play the red sox. So this wasnt a normal regularly scheduled flight, the pilots of the flight today usually flew for everets air cargo out in fairbanks alaska but with the pandemic and everything, they were probably getting work wherever they could find it. A lot of pilots had to adapt during the pandemic. Heres the thing though the MD87, hadnt flown for a while as well. The last time it was flown was on the 26th of april 2021. After a couple of months on the ground, this jet was ready to get back in the air. The captain had flown this jet before and this was the first officers first time flying the MD 87. The pilots got to the airport at 8 am local time and the first officer did a walk around of the plane to make sure that its extended stay on the ground hadnt done anything to the plane. Think bird nests in the engines or corrosion on the control surfaces that sort of thing, he was looking for anything that might make the plane unsafe to fly. Everything checked out. But just to be safe an airframe and powerplant technician from 987 Investments also performed a walkaround of the plane and noted nothing out of the ordinary. Two sets of eyes are better than one after all. But all seemed to be okay.
The first officer and the captain started powering the plane on while the passengers boarded. They ran checks and went through the procedures that you needed to do to get this jet into the air. The captain told the first officer that theyd be using the procedures developed by the company that they used to fly for, everts. Telling the first officer that they would only reject the takeoff after V1 only if the plane wouldnt fly. For those of you that dont know V1 is the highest speed at which you can safely reject takeoffs, with there being enough runway left to stop the plane in time. At 9:52 am the engines were started and the pilots started taxing the plane to the runway. On the way the pilots did a control check, where the first officer pushed the yoke all the way and then back to make sure that the plane was responding to all the commands as expected. Everything was a okay and so the plane continued to the runway. The air traffic controller at this time chimed in and cleared the MD87 to take off from the runway 36. The captain set the thrust levels that they would have to hit, the pilots looked over the instruments and everything looked good. The flaps, slats and the stablizer were all set for take off now the onlything that was left was to push the engines to takeoff thrust and get the jet into the air. The jet started rolling, slowly at first but then it picked up speed. At 9:59 and 26 seconds the first officer called 80 knots followed by V1 at 9:59 and 47 seconds, this jet was going too fast to stop on the runway that they had left now.They would need to takeoff if something went wrong. Just a second later they called rotate, this is the indication for the pilot flying, in this case the first officer to pull back on the yoke and raise the nose of the plane into the air. He pulled back but nothing happened. The jet accelerated but it stayed firmly on terra firma. iT was like the controls were stuck in concrete. Nothing they did had any effect. The first officer then made the V2 call out. This is the minimum speed that must be maintained if an engine fails after V1. But the plane was still on the ground it should have lifted off by this point. Both pilots were now pulling back on the yoke. The CVR picked up the captain saying “come on” as he strained to get the jet into the air. At 9:59 and 53 seconds the first officer made the call he said abort and before the captain could react the first officer reached for the throttles and put both engines into idle and the captain activated the reversers. At the back of the plane, the huge buckets were pushed into the

On a DC9 or MD80, you are only moving the control tabs with the yoke, except when pushing full forward which engages elevator power and a blue annunciator light indicates that elevator power is working. The elevators can move up and down with the wind so I suppose that the bulletin is effective because the elevators probably are weighted to te up normally. @@robertcraig5037

So, MacDonnell Douglas designs an aircraft without a fail-safe elevator system with no hard stoppers or sensors, and Boeing, which bought out MD, said there's nothing can be done about this problem. That makes sense as the management of Boeing had been taken over by ex-MD executives. MD has a long history of designing bad aircraft that caused many crashes, killing hundreds and hundreds of people. With ex-MD executives in charge, Boeing is following in the same footsteps of the infamous MD, with all the problems they've been having with Boeing jets.

Long term parking of an aircraft is actually well described in the maintenance manual. Chapter 10 of it to be exact. It is called "PARKING, MOORING AND RETURN TO SERVICE". Did they followed it? Also, once an aircraft has been cleared by maintenance for return to service, most of the companies would conduct a special test flight for the "Extended Down Time" (performed not by a regular crew but the pilots qualified to do it) in accordance with their SOP in order to ensure that no passenger gets on board of potentially unsafe aircraft.

Yes, sometimes the manual is inadequate. It is almost impossible to cover every possible thing that could happen. I know next to nothing about this type of aircraft. I’m not sure if this aircraft had a gust lock. Many aircraft have some type of gust lock system. The gust lock is engaged to lock the the control surfaces in place to prevent damage from gusting winds. I have seen many cases where engaging the gust lock was overlooked. In some cases there was damage and in some cases there was no damage.

It's too bad that the same accident happened multiple times, but ill give MD some credit that in both cases, there were no fatalities, perhaps a testament to the crash worthiness of the fuselage design.

They may have been able to make it fly with the stabiliser trim but getting airborne with a jammed elevator is not ideal. As it turned out no one was killed so probably the best decision to reject the take off, even though it was made after V1 and by the co pilot.

The Michigan crash occurred in 2017 and was a charter flight for the Univ of Michigan Men's basketball team heading to the NCAA tournament. It was nearly an identical accident and thankfully no one died. Seeing as it too was an MD aircraft parked near a hangar during high winds why wasn't there a safety advisory created before 2020? To be a pilot having to inspect a dormant plane during the pandemic and concerned enough to elicit additional inspection eyeballs, why wouldn't they look at the elevator positioning? Maddening.

One of the problem with T-tails is that they're hard to visually inspect on the ground, and their action is harder to verify during a control check. With two people doing the preflight, they could've had one verify the control response (hindsight).... Wonder how effectively the control lock locks the elevator, or does it? When stored, an exterior mechanical lock of some sort should be used. Bummer to see a nice plane wrecked.....
@Sashazur
@Sashazur 5 месяцев назад
I’m not a pilot, but another thing about T-tails I’ve learned from RU-vid is that they can be harder to recover from a stall. That’s because when the aircraft is in a stall with the nose up, the elevators on the horizontal stabilizer are in the midst of the turbulent flow off the wings, so using them to pitch down won’t be very effective.

There was a somewhat similar event on Air Moorea Flt 1121 in 2007. The elevator cables, in the case, were the problem. In part, there was suspicion that when the aircraft was parked, the nearby jets' blast moved the elevators excessively causing the issue. Wikipedia : "Air Moorea Flight 1121 was a de Havilland Canada DHC-6 Twin Otter which crashed into the ocean shortly after takeoff from Moorea Airport on Moorea Island in French Polynesia on 9 August 2007, killing all 20 people on board. It was bound for Tahiti's Fa'a'ā International Airport on a regular 7-minute service, one of the shortest on earth, scheduled 40 times a day. The crash resulted from loss of control due to failure of the airplane's elevator cable.[1] Frequent takeoff and landing are believed to have been a major factor in the crash, because of wear and tear on the elevator cables, inspected only at fixed time intervals, regardless of usage. Another factor may have been jet-blast from large planes pushing back from the ramp at Fa'a'ā International. "

Again V2 is not "the minimum speed that must be maintained if an engine fails after V1." V2 is the speed at which you would achieve the best rate of climb with one engine inoperative. In other words, if an engine fails, you must pitch the aircraft to maintain V2 and that will give you the best rate of climb which could actually be also the best glide if you are heavy or you are operating at a high density altitude.

V2 only need to meet minimal climb gradient after TO, and margin above stall and Engine Out control, normally it's at or lower than Vx, let along Vy.

For that you need the proper factory maintenance reference and several Airframe and Powerplant mechanics to do all the proper inspections and operational checks before it is ready to get it's MRD.

It’s a good thing that commercial aircraft do not have external cameras like my $29k Kia. It’s 2024 and the most modern and sophisticated commercial aircraft in the world, still have to fly by the tower to determine if landing gear is down or by asking the plane behind them on the ground if their rudder flaps etc are actually working.

I don't care what my employment status is, or how badly I need the work. if I'm going to fly a plane that sat outside for SIX MONTHS, I'll insist on more than a walkaround by two people! That plane would get a full inspection of the controls, and at LEAST a thorough running of the engines, not to mention a thorough taxi test! I'd probably insist on a test flight by a qualified test pilot as well! As demonstrated, too much can happen to a plane sitting out in the open for half a year to half-ass preflight preparations! As far as I am concerned, bad parking wasn't was crashed this plane. It was bad pilots.

Proof that if you have enough runway that V1 nonsense is ridiculous. I’ll always wonder what would’ve happened had Concorde just stayed on the ground instead of taking off on fire. At least on the ground there would’ve been some chance for survival. I’d rather my pilot do every damn thing he/she can do to stop the plane even if involves an overrun. As opposed to taking off and hoping the plane will fly well enough to return to the airport.

V1 is the maximum speed at which a rejected takeoff can be initiated in the event of an emergency and stop the aircraft safely within runway boundaries , useing only brakes , or your company's safety procedures or the aircraft manufacturer recommendations. But why not the use of reverse trust or ground spoilers ? Well, because in case of an engine failure ,means that the thrust reverser in this faulty engine is almost lost on one side and using the thrust reversor on the other side would cause asymmetrical thrust and might cause loss of directional control, especially on a contaminated runway.

@@medler2110 There's no true upgrade. Boeing built software in the plane specifically to allow Mark I human eye to be able to perform visual checks on devices requiring a Mark II human eye. This is so pilots would not have to be certified in Mark II human eye training, thus saving the airline money. Unfortunately, in typical Boeing fashion, they did not build the software with any redundancies should the Mark II human eye sensor were to fail. A Boeing engineer was reported to have notified management of this issue, to which he received the following reply: "Naw...it'll be fine." Boeing also failed to notify anyone that this software system was active in the series, thus pilots were never trained on how to respond and diagnose should the software malfunction. Boeing strikes again. 😀

V1 is not the highest speed you can safely reject the takeoff. This is a common misconception. If you reject the takeoff at V1 you may not stop in time. V1 is the speed at which you can no longer safely reject the takeoff. In other words, you must decide to reject the takeoff BEFORE you reach V1.

Not really familiar with the plane, but man MD-87 just looks wrong - just weird proportions, engines look too small, wing too far back
@randomxnp
@randomxnp 5 месяцев назад
Wing is far back because the engines are, so their weight brings the centre of gravity aft. Engines are a different version of the JT8s fitted to the original 737 (-100 and -200). You are used to high-bypass engines used nowadays for efficiency (and lower noise!). These are much fatter* to get higher airflow at a lower speed to produce their thrust. KE = 1/2 x m x v^2 so it takes more energy to speed up the air more than to push more mass. * which the root cause of the first two 737MAX crashes (those modern engines are too large to fit in place of those old JT8s, so Boeing had to get creative). Of course with the engines at the back (a configuration used to allow short landing gear) the MD-80 series would not have had the same problem updating engines.

@bhtooefr
@bhtooefr 5 месяцев назад
Not a pilot, but AFAIK, the idea is that the act of rotating is committing to the takeoff, and V1 is the speed at which you commit to the takeoff, so there's no concept of V1 ever being higher than VR - it's at most equal to VR. (There's not really a concept, as I understand, in commercial aviation of setting it back down on the runway after rotating, unless the plane is fundamentally unable to fly. Also, once you rotate, there's a lot more variables for whether you can stop after setting it back down.) And, even if a given airplane and runway combination has enough room to set it back down and stop successfully without overrunning, due to how performance is calculated for balanced field takeoffs, it's quite possible that reduced thrust is used for reduced noise, fuel consumption, and engine wear, meaning you don't have that room any more.
