Rationale:
AMS4037P adds -T81/-T851 response to heat treatment test and response to heat treatment to the -T42, -T62, -T72 temper (3.3.3, Table 4), adds ultrasonic inspection requirements when specified (3.4.1), and revises Acceptance (4.2.1) and Periodic (4.2.2) Tests. These changes will help facilitate the cancellation of AMS-QQ-A-250/4.
