I know of 7 r44 Raven2 that have been checked in the last week and all found the same issue - be careful out there.

No! couldn't possibly happen! After all, these parts go through very strict and thorough Airworthiness certifications....that's why they are hundreds of times more expensive than standard, off the shelf components.
