First 757 to outsourced MRO

The safest airline? I'll take you at your word. The airline that outsources its heavy airframe overhauls to places like Aeroman in El Salvador? The airline that has this to say about its maintenance program:



At 12/31/10, WN had just 2,464 maintenance personnel to maintain its 548 737s.


They just have a few blow holes in the fuse due to improper maintenance. Also a fine to prove it,but safety wasn't compromised yea right...At least AA's blow hole was a manufacturing defect.

Wasn't. WN blow a 737 Convertible?
 
By the end the year there will be a total of 75, 757's along with some 767's and MD80's at the later date.
 
The only vendor I know out at ROW is storage. I've driven around the airport at ROW, and don't remember a MRO out there...

No sorry, I meant to indicate that another operation as in FEDX or UPS.
 
That wouldn't surprise me, although I can't see the MD80 being a great airframe for freighter mods..
 
Anyone heard any feedback on the overhauls at TIMCO?

I keep hearing rumors but nothing from the company.
 
On a related note to the original topic...... I just found an old hardcopy of the M&E Plans Book from 1999....

In Section 12 - Economics... they have a table for the learning curve on major base visits & mod programs.

Code:
Aircraft Sequence      Multiplier
-----------------      ----------

 Initial               2.44x
 Second                1.95
 #3                    1.76
 #4                    1.56
 #5                    1.48
 #6                    1.41
 #7                    1.33
 #8                    1.25
 #9                    1.22
 #10                   1.19
 #11                   1.16
 #12                   1.13
 #13                   1.09
 #14                   1.06
 #15                   1.03
 #16                   1.00

This table is for planning purposes only. It is intended for use prior to
the start of new check lines and mod programs and is based on the
estimated level-off man hours required.

These numbers are based on worse case learning curve possibilities.

Man-hour costs level off at the sixteenth aircraft when using the
same work crew with nose-to-tail schedules. Use the same table for 
each production line when more than one line is involved in the 
same program.

In all the haste to condemn how long it took for the first or second checks compared to an experienced line, perhaps you might want to reconsider... If AA has to admit it takes 2.4x more time in TUL or AFW for a first check, then it is a fair bet that it would take at least 2.5x to maybe 3x as long for the first check.

Learning curves are fine, however management must learn also.
