Some engines may be upside down, or not even attached to the plane. This is due to the outsourcing of maintenance to chimpanzees in the Amazonian jungle. This is completely serviceable. You can go! 👍
14:52 - You are missing a couple of fan blades. This is down to a flock of birds flying into the engine. This aircraft is serviceable, you are cleared to fly.
I question the allowance for "small" anomalies and no mentioning of if there are many occurrences or combination of these.

Most people do not complain about the design of the plane with new big engines, it is MCAS as it is suppose to be a safety feature but it turn out to be a killer, Boeing should take note that all safety features should be priced in the selling price and not treated as optional, period
This engine is almost identical to GEnx 1b engines. The composite fan blades and fan case, 10 stage hpc and 2 stage hpt and the introduction of turbine center frames makes me think is this a smaller GEnx? 😅 it’s a great achievement to improve the cfm56-7b engine by this fuel efficient engine can’t wait to maintain it 😊
Sounds like the 737 MAX is too over-engined which leads to high AoA due to engine placement over the 737 NG...which required Boeing to install the MCAS...which lead to disaster.
Somebody at Boeing has an incorrect theory of operation of MCAS which to me suggests insufficient testing or substituting digital modelling for testing.
The 737 airframe or fuselage 52 years old did not have a new engine option. The A320 did being higher off the ground. The Max was a dud right from the word go, Leap turbo fans too big and too heavy, consequently the aerodynamics of the plane were knocked out, but wait, lets install MCAS said Boeing. And so it flew, well sort of. With faulty data from one AOA sensor it flew..........nose down. The solution. Re engine and dump MCAS.
How does this differ from the latest accident reports on other engines by this manufacturer? The world has not seen such a combination of high risk transport options since they had richshaw racing in calcutter...contagien will spread to boeing suppliers unless they walk away from this failed project.
i Just want to know why Boeing is not go with the Boeing B-52 Stratofortress engine type or style? kindly answer me if anybody know? or is it a factor of commercial or defense aircraft?
Obviously the MAX family needs redesigning. What's urgently needed is a taller landing gear that would allow the Leap Engines to be placed lower and backward, pretty much like the placement of older engines so as to use the CG and thrust parameters as it was originally designed. The new Leap Engines are placed in the wrong place.
Maybe flawed design but also over reliance on automation to make up for the experince older pilots have day of miracle on the hudson pilots is setting.

@@j.f.sebastian9696 Yes that was the norm I'm sure but then your engine literally gains a net 15% or so on fuel savings the next iteration, as a result of those super lightweight materials and longer fan blades, so it's not so surprising anymore from a construction aspect. Nonetheless a tech marvel.
@@j.f.sebastian9696 Call for maintenance I guess, however I would expect them to have some tolerances for non-static bending and it would have to be a pretty sudden grab vs trying to slowly coast it down by a blade for instance.
According B737Max-8 Lion Air JT610,last flight before crash,passangers from Denpasar To Jakarta said,the engine strange "roar" sound and couple time like loss power a make them like ride roller coaster during flight... and after couple hour,the flight was allready and have "airworthy" to next flight from Jakarta to Tanjung Pinang... Then after take off just 12 or 13 minutes,the plane crash/plunged to tanjung karawang sea... First And Fatal Accident for First B737Max8...
Yes I know that. Are you implying the engines somehow caused the crash? The preliminary comments suggest there may have been an issue with the flight instruments.
on brand new plane? this like massive failure system that likely bom can did it with instrument with backup system....or fatal damage from the inside the engine....carbon fibre blades and ceramics turbin ???? this is unkown yet ....need time
Yes the engine is a new design. From what is reported the aircraft was having difficulties maintaining level flight the day before. Seems like a computerised flight control issue. I think the evidence from the maintenance engineer who cleared the aircraft before the crash will be important for the investigation as will the black boxes. I like Boeing aircraft but I would not be keen to currently travel on a new 737 Max8 until this crash is fully and independently investigated.
Can an aviation expert inform me how bigger engine or more powerful engine makes less fuel consumption ?? As I know in any mechanical system bigger engine means more fuel consumption ......
Lower rpm for the same amount of power as the older engine acheived through higher rpm. An engine that has power sooner and revs less will consume less.
From all the write up you will summarise that the cause is the new software installed and Boeing just sell their product and not educate pilots what the software can do to a aircraft
Don't you wish you could go back in time and tell Boeing and CFM that this is the wrong engine for the 737? This engine would have been perfect on a 757.
Same engine installed for Lion Air JT610 and Ethiopian Airlines ET302... All casualty have similar problem... Are you sure this engine are safe? Consider both aircraft are brand new and below half year routine flight.... The latest technology not guarantee for our safety.... Old school turboprop better more than modern "flying coffins".....
agus wijaya Leap1A is installed on airbus 320, no problem for years. It is the design and software flaw by Boeing, not the Engine or CFM. The engine did not fail. Wrong commands were fed into the engine by the software.
@@wangfengfight You are right. The engine is not the culprit. The problem was that the engines were moved closer to the fuselage as well as moved forward to avoid the huge engines touching the ground. This is because the 737 is traditionally built to be as low as possibe. The plane is so low that actually there are no doors for the wheel wells .....as , if there were doors, then , when in open position they would scrape the ground....so in 737...no doors for the wheel wells. All this shifting of the engine position has resulted in aerodynamic changes including lifting of the nose up due to the enormous thrust of the low slung new engines....it is to correct this nose-up tendency that the MCAS was devised...which now has become the issue.
@@rajarams5988 Yes the larger moment (force x distance from pivot point) during max thrust seems to make the airplane unstable, and until the 2nd crash, MCAS was thought to be able to recover stable operation under all known conditions. Now we can guess that there are unknown unstable conditions MCAS is unable to recover from.
Nah, the problem with the max was simple. It handled different than the NG, and the software was made so both flew the same. That way you wouldn't need any simulator training for the MAX... it has been proven and tested by EASA that the plan can safely fly and operate in all condition without any software help. Also.. a software to correct or modify a plane behavior is pretty common. As a matter of fact. The B737 (any version, including the MAX) is one of the less complicated airplanes, the only big airlines still in production that uses hydraulic controls over fly-by-wire. So the pilots control the aircraft directly. In the case of any airbus, the plane is flown by a computer, and it's behavior is heavily modified...
The point of this video is to give pilots a way of PRIVATELY studying procedures less the stress of always doing it in class. I think you'll find that CFM considers the video as support material that in no way replaces formal pilot training for this new engine. What I mean is... download it and put it in your phone/tablet/notebook and study it when you are relaxing and can best absorb the material. It is also a good reference to look at during a flight when "George" is flying the plane, as long as you don't start pushing buttons! Sorry Kevin, but I think this is a GREAT video and shows SUPERB foresight and imagination by CFM. I'm a Rolls Royce man myself, ( I mean that's who I support), and wish someone would, somehow, give them a contract to develop an equivalent engine! I am confident it would be as good as if not better than this Leaf. Hallo Theresa I'm talking to you!
All Airbus aircraft have a major design flaw the Airbus will not admit as if they do Airbus will be charged with thousands of manslaughter cases. On Airbus, the Co-pilot can be moving the flight control stick in the opposite direction to the Captain at the same time and neither will know. Also, if one of the pilots move the control stick on his side the other pilot will not know which way he is moving it. This has caused many Airbus to crash and kill all onboard. Carefully watch this RUclips link Captain Sully explain why you should never fly in Airbus ruclips.net/video/kERSSRJant0/видео.html
Hop Lam: The Leap engine has not killed anyone....it's Boeing's failure to provide a redesigned and larger elevator is what is causing the 737 MAXs to nose dive into the sea/land. Relying on MCAS is not good enough. When Boeing placed the much larger Leaps on the 737....it changed the flying-dynamic characteristics so much...at Maximum Takeoff Thrust...with the newer Large engines hung lower and further ahead....the plane naturally wants to pitch-up at maximum thrust...in instances like takeoff and climb-out to initial assigned altitude. Boeing should have given the 737-MAX a bigger rear wing "aka elevator" to counteract the effects of the new engines. The sick part is, the FAA ever approved it fly at all. Sadly, a software fix to the MCAS won't stop future deaths....only a fail-safe larger elevator will.

MCAS in 737 MAX only uses 1 sensor which is not very proper development. They should've put 2 instead of 1

Shadow Opp.'s RC There’s no reason RPM is a problem
