DalMD88, I'm not familiar with PSV and Letter checks. In Tulsa we do Heavy C, Light C, and drop in work on MD80's, 757's, and A300's. We're told we do the only 3 day light C's in the business. There's a big initiative to cut turn times almost in half on our heavy's (MD-80's) and it's going very well. There's been a lot of articles about Tulsa's big plans and we'll be featured in some maintenance magizine in the near future. Wall street will certainly be watching AA as well. BTW, from what I heard from one of our first docks to implement major improvements, management didn't show much interest in their method of improving turn times but they did it anyway and suceeded. Survival of our profession may be left up to us dispite management.
