On a D-check, done once about 5-6 years
|Quoting EMBQA (Reply 3):|
D-check from what I see are a thing of the past with newer aircraft. The C-check has become the driving inspection now a days. The C-check has been broken down to more intense levels such as C, C1, C2..Also, many aircraft are now driven by cycles such as a 12K, 30K inspections

At DL our MD88 fleets get D check at 6 years. I think the 737 classics were the same.
|Quoting Tobi3334 (Reply 10):|
Certainly this has nothing to do with "safety" but acutally I thought that also these parts will be replaced on D-Checks
|Quoting 320tech (Reply 13):|
As much as we'd like to think so, an airplane just out of a D check is not really like new. Many wear items - control bearings, for example - will get replaced, and structural damage will be repaired. But in most cases, you still have the same old aluminium under the paint.
|Quoting 320tech (Reply 15):|
I haven't seen any big patches, like on the 737 upper fuselage. I've only seen patches where someone beat the airplane (baggage handlers, jetways, etc).
|Quoting 320tech (Reply 17):|
They are done pretty much the same as on a 737, though.
|Quoting 320tech (Reply 19):|
I've seen lots of patches, some of them pretty ugly. Just never thought to take a photo of one
|Quoting HikesWithEyes (Reply 21):|
It is not uncommon for aircraft coming out of D-checks have some "bugs"
that take a few weeks of revenue service before they are identified
|Quoting HAWK21M (Reply 22):|
A test flight Post Check D will help judge.
|Quoting HikesWithEyes (Reply 23):|
I agree, but my experience has been that there are always some
little problems that keep surfacing for a few weeks, if not longer.
|Quoting Airfoilsguy (Reply 25):|
D check sounds very costly. Anyone know the cost
