A First Officer reports about delamination of the Captain's forward windshield on a B717 aircraft. Two Mechanics refused to sign-off the window delamination because it was out of limits. The Maintenance Supervisor arrived and without looking at the window condition; signed-off the logbook write-up.

Narrative

Upon Arrival for flight; the Captain and I started our pre-flight of the B717 aircraft. Captain found his (forward) windshield delaminated. He asked me to give Maintenance a call; to come and check out the windshield. Two Maintenance personnel arrived and found that the delaminated window was 1 inch out of limits. The maintenance crew then radioed in to their Supervisor to advise him that the windshield was out of limits. Captain and I heard the Supervisor call back and say; 'Sign it off.' The maintenance crewmember said; 'It is out of limits and I am not going to sign it off.' The Supervisor then said; 'Are you scared?' The maintenance crewmember then said; 'I am not scared; it is out of limits and I'm not signing it off! If you want it signed off; you have to sign it off.' About 3 minutes later; we see a Supervisor come up the stairs of the jetway and walk straight to the logbook and signed it off without looking at the delamination on the window. Then the Supervisor walks into the aircraft and looks at the window; pushes on it; turns around and says; 'Your window is fine.' I made a comment to the Captain I can't believe what he just did; (he) signed it off without even looking at it and not even measuring the delamination on the window. Captain got a call back from Mr.'Z'. He advised Mr.'Z' of what happened. Mr.'Z' advised us to write a pilot report and he would be looking into the situation. He never advised us not to fly the flight. In-flight back; Captain saw that there was a scratch in front of the delamination on the window. We had a jumpseating pilot; from a different carrier on board; and all three of us agreed it needed to be inspected. Once we got back; we wrote up the scratch on the window and also requested the delamination on the window to be re-inspected. Maintenance met us at the aircraft and inspected the aircraft and found that it was out of limits and grounded the aircraft. The event occurred due to the unprofessionalism of the Maintenance Supervisor. I would suggest getting rid of the Supervisor. If he is pencil whipping in front of our faces; what is he doing behind our backs?
