Engine chip warnings
Seasons greeting to all
Question for the AMEs, is it normal to see both engine #1 and # 2 chip detection on the same aircraft within the space of one week?
We've just had one of our buses over here get two chip faults, engine #2 on Dec 27, was changed out and placed back in service, then engine #1 had a chip fault two days later (Dec 29). Splinters were deemed within limits for a serviceability check. From what I've read in the customer flight notification bulletin the serviceability check will take approximately 4 hours after which the aircraft will require a ½ hr ground run, ½ hour hover check followed by an inspection of the chip detector.
I would have assumed that engines are ran to stagger operational hours, so is there a shared lubrication system on the S92 that could cause cross-contamination, I would have assumed not?
Safe flying
