Some may remember a service bulletin that came out
on Precision Airmotive fuel servos a couple of years
ago. A number of units manufactured in 2007 had
defective gaskets that caused a vent-plug to loosen.
This is a flight safety issue causing at least one
known off-airport landing. The S.B. number is PEX-1
and can be found at www.precisionairmotive.com.
Earlier this month I received a brand-new SilverHawk EX,
and found the same loose plug problem! A little research
revealed that my new unit was one of those manufactured
in 2007, and it had never been repaired as the S.B.
requires. It has been traversing the parts supply
pipeline for three years with no-one paying any
attention to S.B.'s from the manufacturer.
This a good reminder not to assume that "new" parts
are not subject to a S.B., A.D., or otherwise in non-airworthy
condition. You have to go back to the manufacturer
and check.
