DO: Remove the fire sleeve during periodic inspections to verify that
nothing bad is happening to the line underneath.

We had an engine fire on one of our airplanes because the oil tank vent
line deteriorated under the fire sleeve.  As it cracked the fire sleeve
soaked up the oil.  There was no evidence from the outside.  When the tube
finally broke the blowby gases impinged on the exhaust manifold and things
got real interesting.  If it hadn't been on the ground I might not know
what happened.
