This quote is also from my addendum (supplement) to my first report, and refers to a requirement in the Boeing QA Manual:
Manual retests: Another case where shop is performing tests without inspections is on the 737NG EBU fire detection system. They check the fire loop for a certain resistance reading, like XXX ohms, plus or minus some value, on job N93250 (L/N 1096), operation 190. The operation is titled a continuity test, but if that was the case, there would be no inspection operation and no ohmmeter would be required for the test. This should be witnessed or "verified," by the inspector checking the resistance himself. But it doesn’t happen. A "verify" inspection is in operation 190, just like there is F/T paperwork for some engines, but we just take shop’s word that the test was done, without the required inspections.
This just in (it’s 3/11/02): I was doing an NCR search last week for a specific NCR when I stumbled across a few NCRs in which I had written shop up for the same thing, lack of required witnesses on manual tests trying to be sold as "verified" only, some years ago. Reference NCRs (number) and (number). I believe they were written on the same functional test mechanic’s work as the recent ones were--(name). They were probably also similarly roller stamped on second shift also. These old NCRs prove that this problem (uninspected roller stamped tests) has been going on for a very long time at PSD.
