Quoting NicoEDDF (Thread starter): My understanding is, that most of the B-Check work got rendundant because the work is done either
Letter checks (A, C, and D, as well as B) actually disappeared with the 737NG. Now you can have the maintenance plan rearranged in a multitude of ways to fit your operation. Everything from "Do a little bit every night and that's it until heavy structural checks" to "Don't touch the airplane for several weeks then do a big check".

Yeah it does depend from type to type. But no check will be totally obsolete. Whilst there is the potential for things to break, the aircraft operators will help to find them and fix them. they dont want to compromise the astonishing safety record aviation currently has.

You split the check so instead of one big check which might take days, you have secveral small checks which can be done overnight with the aircraft flying pax in the day

It all depends on the operator, the aircraft, the manufacturer, the regulatory authority and the approved maintenance program for that aircraft type. One operator may still do B-checks, while another does not.
We still do them on our DC-8 aircraft, but on no other. We do A-checks on our B747-classic, but not on our other Boeings.
Maintenance programs evolve. We've eliminated D-checks because we've segmented them into our C checks. We've shortened our C check times (certain segments) by incorporating some tasks into our non-major maintenance program.
It's all designed to maintain a high level of safety and reliability while at the same time limiting the expense of keeping the aircraft on the ground for extended periods of time.

This is exactly what WN does.
A Safe Flight Begins With Quality Maintenance On The Ground.

No clue. I seem to recall that PanAm took 30 - 45 days at hangar 19 at JFK, but I worked at 17. Never really got involved in the "D" check.
I'm not sure anyone does a D check on B747 anymore. We do segmented C checks that incorporate D check tasks in the C check.
