The correct procedure for replacing a fwd cockpit window on a B737 will be found in the Boeing Aircraft Maintenance Manual for the B737-? model specific.. .As to how long it takes to change one, several hours, also to be considered is the removal/refit of the roof trim, glare shield panel, the best part of the instrument and autopilot panels and function tests required for these.. .Aerodynamic sealant cure can be aided by the use of short working life versions, heat and hi-speed tape as per AMM.. .The MEL, these are company/regulatory authority specific from the MMEL. So quoting what is allowable for one operator maybe different for another. . .As to the comment about the BAC1-11/B737 windshields earlier, the B737 windshield is mounted inside the flt deck window frame.
