This seems like a potentially much worse problem than the OP topic.

Forget to turn the engine heat off in certain conditions and the engine pylon might melt off, with a possibility of the engine smacking the plane as it detaches?

I guess (?) this must be an extremely unlikey possbility.

I certainly don't believe Boeing when they say "but we'll totally fix this by 2026" (after a couple hundred planes are in the air)
