Narrative:
During the aircraft preflight; the APU/hydraulic drain mast was found to have multiple fractures. Maintenance was called and when they inspected the damage; they found it to be two times beyond the approved limits for a temporary repair. Operations wanted to get an 'engineering authorization' to make an exception to fly the aircraft the rest of the day. The authorized and approved repair had already been 'engineered' and I did not feel it was safe to make an exception to the already approved exception; especially since we were at a major maintenance base and there were other aircraft available! After some delay waiting on maintenance and a decision; I informed operations that I would refuse the aircraft and to get a new one for us. The other issue was that the first officer and I were already scheduled for an 11-hour duty day and by now; we were going over 12 hours. We got a new aircraft and continued our trip; taking our passengers; 'customers' to their destination. 'Pushing' to move aircraft puts safety and common sense secondary. Don't accept 'exceptions' to 'exceptions'! Especially at major maintenance bases!
