No, they are amendable.

The fact that the FAA had to step up and tell Flight Satndards how to fly the plane they have had for the last 20 years displays the true incompetence of the cube dwellers that can't or never fly.

The irresponsible numbers that management said were safe, are obviously not, and finally they have been turned off.

SkyWest had this coming and it's embarrassing.

With any luck it will get somebody fired in SGU, but the normal management fashion I'm sure they will just blame the pilot group.
