Quality Controll, O/H Parts
During the last two years many items on my little aircraft reached their TBO or calender dates, what I have found is that there seems to be a decline in the QA of many of these parts, eg: In the last month we have replaced two Tach Gens, overhauled, tagged, it took us three units before we had a servcieable unit, two failed at under five hours.{Yes they were installed as per spec} Had a R/H engine driven alternator fail, replaced with new, faulty oil seal, oil all over the place, also alternator clutch unit faulty. All these parts were purchased from aproved supliers, with tags and full traceability. I hesitate to mention the supliers but are others finding a decline in the QA of parts, or am I just getting old and cranky?
