What does it cost when you "firewall" an engine?
To start with - this is not an effrot to make pilots consider whether or not to Firewall and engine based on costs - when you need it you need it !!
Nevertheless - you go out, encouter a serious windshear on TO - and firewall the engine - and of course - write it up. Did you just buy the higher rated engine? Do they check the FADMS download and Pro Rate the info for Maintenance cost? Do they let you off the hook - Maintenance cost wise - if it was for short duration?
How do it know?
