The flights are safe only because the pilots are demanding the company keep them safe.
The intent of an MEL is to allow a company time to gather their resources to properly fix a problem. USairways regularly violates that intent by stretching each MEL to it's legal limit, then changing a part just to extend the MEL another cycle. If they cannot fix the problem I have seen them get a last minute extensions several times. I find it quite suspicious that they can get a waiver within a few minutes on a late Saturday night. Perhaps, next time, I will require a fax with signature for follow-up.
I want the logbook concession. What a joke the new logbook is. Instead of being able to research a problem for several weeks, aircrewmembers are limited to several days at a time (yeah, there are that many write-ups). US now has two logbooks on each plane, one for airworthiness issues and one for the cabin. Most cannot even find the cabin log, much less fix anything in it.
I have seen aircraft flying around for weeks with bleed valves not shutting air supply, in one case, enough bleed leaked to run a pack. Improperly fixed in each case, not because of the mechanic, but because of MOC. Missing panels for weeks (in one case I bet USAir spent more in gas than it would have cost to replace the panel.) Planes sitting for six hours and overworked mechanics regularly get to the plane just prior to scheduled push.
A giant joke is notifying MOC of write-ups via ACARs or radio. The mechanics never get the word.
Yes, safety reports were filed each time.......to no avail.
I could go on but, unless the employees revolt, US will never see better.
