AW139 PCM

Looking for anyone who has had trouble with their PCM from factory new. Specifically failure of the return shuttle valve when hooked up to the service cart such that the service cart fills the tank and overflows the system through the overboard drain (Overpressure) valve. We have a 28% failure rate in fleet.
Only one was caught durring the warranty period and they have denied the MMIR's for the others. Looking for instances of similar failures to help plead the case.
AC built in Italy. S/N in the 10-60 range.
Just wondering if we have three anomoulous PCM's or if Gary on the assembly line was sleeping for a bunch of them...
