@mantodowhattodo what the- No. They aren't required to replace them with "brand new" ones. Engines can be kept in the air indefinitely, given it doesn't encounter SB and ADs that would require a major overhaul. As long as regular drop checks and scheduled maintenance is done, as well as replacing any worn part. Not always economically practical to do on the plane. It would cost the company to much money to leave a plane grounded as long as it would take to, say, pull the HPT and do a disc change

Lets see it in flight !!!!

@qwerty112311 I see, found a document on Google which says that the blade-off test for this engine has been done at 2580rpm. Must be the full power then. Found also that the rpm's for an CFM56 engine are about 5000rpm for idle and 15000rpm for full thrust, i was probably confused with the sound of those speeds :-) Bigger airplane = lower rpms.
-
@Engineer9736 I'm almost positive that it is at full thrust. No way it is idle.
-
@ulooklikeadope I was just about to mention that.

At least they didn't use a forklift to mount the engine like the bozo's that worked on the 191 flight 2 months before the rear flange on the pylon that failed and the turbine flipped over the wing before e plane crashed!

@jetfreak4 Dont forget get to put 115-B they Sound GREAT!
-
Why only the right engine? Nice video!

The 777 has the largest and most powerful jet engines in the world, not just in civilian aviation. Also, the engines pictured here, the Roll Royce Trent, is not the biggest...the GE-90 is bigger.
I am originally Iranian and I'll be the first person in my family to be an airplane mechanic. I am taking my A&P license test this week and hope to do this one day. Where is this hanger? I see so many lightenings. Is this Tampa, FL?

@jonny2k100 Engines eventually will wear to the point where they are less efficient, at which point airlines are required to replace the engines with brand new ones.
