Engine fire as a result of IFSD??

Doesn’t that put an end to 180 & 240 minutes ETOPS then in the event of IFSD?

Let alone continuing on 3 of 4 assuming adequate terrain clearance when the next one fails?

I’ve been P2 on 6 3-engined ferrys all of which had the fan etc tethered by proper engineering kit, especially the one with the remains of a borescope in it!

And yes, there was a 747 transiting through Europe with the front end tethered by a collection of leather belts and other Heath Robinson improvised devices. It was impounded by the relevant xAA until a more airworthy solution was found and the subsequent dispatch proven as legal and compliant.
