Well, now that you mention it... they would probably have saved quite a bit of money had they done what every other airline with excess capacity of newish frames does, and either 1) lease the frames out to another airline or 2) kept flying the frames at reduced utilization. But instead they decided to let two of them rot, and then had to refurbish them at considerable expense.
You are arguing in vaccum.Why AI kept 3 x B77Ls
1) B77L are niche plane, limited resale market
2) AI managed to sell 5/8 to EY
3) AI was taking B787 deliveries, supposed to be fuel efficient if and when they fly
4) There were no potential(even cost brake even) ULH routes.
5) Prior to B787 deliveries it was using these to Japan.Mothball (vs) Variable Usage
If you really care about cost and resale value you mothball your surplus capacity. You want to showoff or your lessor won't allow you to mothball, go with variable usage option, which is more expensive.
AIESL in-house reactivated these planes, there was no considerable expense
. That is a myth.
I guess you are call the dirt as rot. Missing engines,avionics and removable control surfaces is a standard long term storage practice. If you store a surplus frame at one of the VCV long term storage providers, they do exact same thing. Covering windows with mylar and presentation are optional.
Two theories here: 1) that AI's 787s were somehow inexplicably worse than other 787s in the same production block or even in earlier blocks (ANA's LN 7-9 and "terrible teens"; or 2) that AI for whatever reason was not driven to fix the issues in a timely manner. I find one more believable than the other..
You can interpret whichever way you want, that doesn't change the reality. Some frames from same time frame are not even delivered yet. Looks like general consensus is up to LN99 are iffy.
Who else had
-Central wing box repairs.
-Both bad engines need overhaul
-Both engines had fault in the accessory gearbox and need to grounded (of the total 8 bad GEnX engines 2 were on ONE AI 787)
-Had an un-contained engine failure before delivery
-Hydraulic line rupture and structural damage before delivery
-3 FMCs failure
-RAT disintegrated during taxi
-Constant windshield cracks
-Constant spoiler actuator failures
-Constant software glitchesWhich of the above can you contribute to AI mx practices
Ethiopian, China Southern, ANA, JAL and United all have frames from the same block. All of them had to do some updates. All of them finished the updates in a matter of less than a week. AI, on the other hand, took twice as long to do the updates as Ethiopian took to repair an aircraft (which also happened to be from the same block) that got mangled by fire.
Small fire repair took 6 months, but 11 months for central wing box fix is out of ordinary!!!
Each GEnX/GE90 engine overhaul takes 2-3 months at an AI facility. Six months for both is normal.
