I used to know a young man that could identify almost any automobile just by looking at its headlight. I wonder what star mechanic can identify an aircraft by its gasket.

There is a plane that seems to have repeatedly missed its scheduled maintenance and it would appear there is a failure connected to its o-ring; which seems to be more of an oblong shape rather than an O.

Something like this: (may not be to scale or color accurate; not rigid).
