According to the report, a pilot inadvertently extended the lift dump spoilers, something that should never be done during normal flight. It caused the aircraft to loss lift suddenly.

The report also blame the insufficient crew training about the lift dump system.

The report's conclusion also mentioned that the aircraft operator failed to obtain necessary approval for non-scheduled flight

gambor pilot ada?

tot lift dumper only deploy right after tyre touch runway?

pilot noob

pilot confused with in-flight spoiler?

Lift dump spoiler normally for reject TO and landing

Should have disabled this during mid flight. At this rate AI should take over pilots.

lift dump spoilers? Isn't it called speed brakes?

Maybe small plane less logic

If big plane I think logic can be implemented to disable

Maybe they can send info to manufacturer to implement due to this accident

is that flaps?

Technically the same

do u guys think the pilot and copilot still awake during freefall? what are their last thought i wonder

inb4 : my mom

yes for big planes only can be activated when wheels touch the ground

tak sempat kot, freefall so low and quick
likely happened right after pilot disengaged autopilot and do landing checklist

No. It is not flap. It is a device that used to reduce the lift. It can be used when the pilot need to abort take off, or when the pilot need to reduce the aircraft's speed.

Should play more Microsoft Flight Simulator like MH370 captain. Konon no pilot also can flew all the way to Aussie.

Elmina property price didn't sink...free publicity now ...

last recorded transcripts

Southern Indian Ocean != Australia

The yeti airlines flight 691 CVR was also leaked few weeks ago. You all should check it out.

1 mins then gg?

Thanks for the info

Salahan manufacturer. If WOW sensor detects aircraft still in the air, there should be a logic to prevent the lift dumper from being deployed. Such a basic safety net also dont have, better stop making an aircraft.

Shit they were alive till the end

Thought would have blacked out

RIP

Woah woah woah


Oih oih oih


The end

That was what my pilot trainer friend said also after watching the crash videos. He said most likely the pilot clicked something he shouldn't.

Betul, I watched too many Aircrash investigation in Nat Geo to understand this

so this is the case of #kapalterbangbodo?

Oh wai is it too soon?

Surprised that the MOT website hasn't had the internet hug of death yet

But mirroring the report here just in case it goes down

intresting

That "what's going on?" part indicates 2 possibilities....

1) The pilot noob switch open lift dump.
2) Electrical malfunction cause lift dump activate.

My money is on the later.

12 seconds only

caught off guard with no height to recover

This one for breaking? No ?

yo this is fucked up

they were awake till the last moment

rip to pilot, and moto guy who happened to be at wrong time wrong place

Yeah if not meant to be used during flight , why is it allowed to extend during flight

yup

pilot noob open it mid flight

12secs.

Probably can't even double check what went wrong in the short time.

well im no pilot or aviation folks, just reading the report for funsies.
the report conclusion & appendix do say primary cause is pilot error. report also say Pilot is not sitting on the pilot seat (instead he seat on the co-pilot's seat, while the co-pilot sitting on the pilot's seat), both are not sufficiently experienced for this aircraft model. SIC is second-in-command, referring to the co-pilot, and the co-pilot seems to be the one controlling the plane.
primary cause: SIC switched on lift dump during landing approach, lost altitude
additional findings; insufficient crew training

reading further on the report amendments section can see the company did tried to deflect/argue that it's not company's fault

I was about to say it’s a 1993 aircraft what to expect. But then my co a/c was manufactured in 1993 and has fail safe system which can’t deploy unless WoW.

yes. the purpose is to slow the craft down immediately. and if u do that when the plane is up in the air, then.....

from google "A lift-dump system, designed for activation once the wheels are on the ground, makes braking more effective."

so sic and pic baru unlock, tetiba malfunction and terus activate?

.

Seems like a basic error of the airplane itself to allow the lift dump spoiler to be activated mid-flight.

Yeah. This is just a case where the pilot is used to driving Tesla, suddenly asked to drive kancil manual and don't know what is the function of handbrake.

I don't know how common the term of "lift dump" to pilots, but to layman like me, this is the first time I hear about it as opposed to the familiar "speed brakes".

I compare the cockpit or G4 and this plane, in G4 the speed brakes is labeled as "speed brakes". Probably the co pilot think "unlock" means move the extend position.

Awaiting ACI documentary to cover this crash. When it did, I hope it will interview our local investigators (if the government allow it).

come see how many pakar beechcraft giving comment here.

tak baik bang.

sorry bang.

cuma u expect the pilot tak buat silly mistake like this

If these people jumped right before impact, maybe can survive

Report says "no pre-impact failures or malfunctions of the aircraft flight controls."

Most likely event was this:
"The accident resulted from a misunderstood checklist item, leading to inadvertent ground spoiler deployment."

So suppose to unlock but not extend it but someone (high probability) went and extend it.

The thing impact is so big, so fast already crashed? The opening of flaps can't be reversed or malfunction locked up?

Last minute. Waoh Waoh Waoh.

maybe pilots need to practice emergency landing

Lift dumper tu apa...

takkan so bodo itu pilot. from which skool of flight?

Tak buat checklist B4 landing betul 2 la tuuuuy

Lift dump spoiler is the same as speedbrakes spoiler?

Betul

Macam 737...landing gear sentuh tanah, teleflex cable, tarik interlock valve.ground spoiler up...

wah dah setahun kes

Spoilers can be used to "dump" lift and make the airplane descend; or they can be used to slow the airplane down as it prepares to land. When the airplane lands on the runway, the pilot usually brings up the spoilers to kill the lift, keep the plane on the ground, and make the brakes work more efficiently.

technically they are the same thing. ok. got it.

Eh long time no see

ramai pilot & aircraft engineer sini.semua pun tahu & pro

damn

rip man

Why say "blame"?

why the flap can be activated mid flight is beyond me. shouldnt there be a failsafe feature where it cannot be activated if its exceeding x-meter from the ground, or if the plane is at x-m/s

Almost 90% of crashed is caused by human error.

As predicted

If the Elmina crash pilots are piloting an Airbus A380, and the flight is full, and they do the same mistake, you can imagine how many people will die.

Try to see the background of the co-pilot,
Arwah maybe new to that plane, but he is an experience pilot.

Turn out to be cousin to a personal friend.

Unlikely, A380 is more like a flying computer....

Salah duduk tempat duduk


Owai…

wah only today found out /k banyak pakar beat aeroplane

Just 12 seconds only.

RIP.

its the last best place to crash without involving another casualties. imagine if the plane crash at the residential area @ subang bestari or subang perdana. the pilot must done it with reason.

Air brake..
Those did airplen simulation also knows this.

Why not? 1997 1998 already played f22 raptop/lighting simulation games. Back in win95/98
N there plenty of recent airplane simulator

Is this the effect of keep taking in unqualified people for the job and lowering the standard/education required?

dari pendapat aku perkara ni takkan terjadi kalau tak langgar SOP.

tau je lah orang kita ni mcm mana. sambil lewa. lagi banyak pengalaman lagi overconfident.

lift dump spoiler tu asbab kemalangan je. tapi pelanggaran SOP tu yang lebih nyata.

Begitulah kisahnya bang

Please correct me if I am wrong. I thought Airbus's computers were not designed to override pilot's action? When the pilot operate any control surface, it will signal to the computers that the pilot want to take control. Isn't it? Then, autopilot will be disengaged automatically, right?

lol don’t know if trolling or not

if not this is the dumbest comment I’ve ever seen

/k always got pakar in everything

The pilot in command (PIC) has 36 flying hours on type and has a type rating for the Beechcraft 390 Premier 1, whereas the second in command (SIC) has no type rating for this aircraft type and had 3 flying hours on type up to the crash flight. In fact the day of the crash was his first day flying the Beechcraft 390 Premier 1. His 3 flying hours on type was made on 2 flights earlier on that day. He was flying as a SIC without having receiving prior type training, it is not a surprise he was unfamiliar with the controls and mistook the "unlock lift dump spoiler" checklist item for errorneously extending it.

The management of the jet charter company is to be blamed for assigning 2 pilots inexperienced with this aircraft type to operate a revenue flight together. Beechcraft is also partly at fault for poorly designing the lift dump spoiler control, allowing the lift dump spoilers to be extended inflight.

Not really. the 2 pilots have plenty of hours and the second pilot had more hours than the commanding pilot. Just the second pilot lack experience for this specific aircraft.

The company also exploit loopholes to reduce the paperwork and inspections required. They also to be blamed

How can they let a incompetence pilot fly.😅

add another final confirmation for rookies
