This quote is also from my addendum (supplement) to my first report.
Please investigate the 777 strut and EBU (Engine Build-Up) programs at PSD to see if we are controlling any key characteristics per HVC (Hardware Variability Control) plans, if we have any. This is a customer and Prime Division requirement. It may be more...indication of us defrauding our customers in not making sure we meet requirements that we promised them, rather than a strict violation of FAA requirements. I’m not aware of any specific key characteristics on a particular drawing, but 777 Engineering can point you in the right direction, I’m sure. A good place to look for key characteristics would be on aerosmoothness drawings such as:
Drawing (I.D. number), aerosmoothness drawing, zone D8, flag note 3.
Update: I got the opportunity to work the 737NG EBU line yesterday (2/25/02) and I gathered some info while I was there. I forgot that the 737 drawings got updated to 21st century requirements during the NG Program, so key characteristics are not limited to the 777, it seems. On the aerosmoothness drawing, (I.D. number) sheet 1, General Note GN06 in zone C5, states that the measurement points used for final fit verification on any interface should be coordinated where practical with HVC points identified on...drawing (I.D. number) sheet 6. That drawing sheet shows key characteristics for the 737NG powerplant.
