I doubt seriously if American pilots care too much about CAP 513, whatever that is. Here's the pertinent FAR:
Sec. 121.565 - Engine inoperative: Landing; reporting.
(a) Except as provided in paragraph (b) of this section, whenever an engine of an airplane fails or whenever the rotation of an engine is stopped to prevent possible damage, the pilot in command shall land the airplane at the nearest suitable airport, in point of time, at which a safe landing can be made.

What some of us Microsoft pilots forget is that a long haul 777 has a lot of fuel to dump before it can get down to landing weight. After the dump and diversion, JFK was probably nearest suitable airport in point of time. And it was an AA maintenance base <g>...
