So does anyone have any statistics regarding windscreen cracks? A fleet of 17 aircraft in service for 13 months having three occurrences does seem high. Same airframe? Have any of the other operators experienced problems? Is this a screen manufacturing/design fault or a "mounting" issue?
In terms of stresses, with the 787 being a predominantly long haul bird the number of pressurisation cycles will be lower than a shorthaul equivalent? Additionally the 787 is pressurised to a lower deltaP than "conventional" airliners.
Something fundamental going on here - or just unlucky?
