This quote is also from my addendum (supplement) to my first report (continued from previous day's quote):
I have noticed problems with our drawings matching the AMMs (Airplane Maintenance Manuals)/PPBU (Power Plant Build-Up) Manuals. I think I heard a rumor once that we weren’t updating our AMMs/PPBU Manuals (because of MRB (Rejection Tag) changes?). At least our drawings seem to be better than the AMMs/PPBU Manuals, though you’d expect we'd want to have our customers see our best, not our worst. I’ve submitted one change for an AMM (reference PCR # TBC-PCR-XX-XXXX-XXXXXX), though I’ve actually read very little from AMMs/PPBU Manuals, considering how much is out there, so far.
Representative installations:The (installation number) (Thermal Anti-Ice) duct installation on job (job I.D., model I.D., line number I.D.).
...Drawing (drawing number) sheet 5 has three views of link fasteners. The views seem to indicate a head (direction) position is required (pictorially, which violates drafting standards), regardless of the position of the clamp-up bushings (which violates (the design standard) and conflicts with the above two drawings), which matches (the engineering specification) requirements. But drawings trump spec requirements, and fasteners are not supposed to be shown in detail, so which direction the fasteners are supposed to be installed in the above (noted) drawings is anybody’s guess, because there are lots of conflicting requirements. The only given is that these (noted) drawings are typical of the quality and interpretability of our drawings at (BCA), where fastener installation requirements are concerned.
