That's rather odd to certify to one standard and design and install to another, but that's how the contract read. And that was missed.
Well the military has always had- required greater shielding and power- instrument- safety separation for reasons of EMP hardening generally above FAA standards. Most old timers in Boeing knew this- but the few remaining were igmnored by the latest whiz kids- it was that kind ofv issue that fubared the italian and japanese tankers in the early 2000;s Thebasic 767 airframe WAS mil certified in early 2000 oor so. But the mcdoug types wanted it thier way and drove the costs/lease issue in 2001 to a fubar squared cluster.****- And the rest is history !
