Narrative:
The #1 CADC was changed on aircraft. Pitot static leak check was not performed. ZZZ gpm states a leak check is not required for CADC with quick disconnect. However, xyz airlines gpm states a leak check is required regardless if CADC has quick disconnect or not. The CADC installed does have quick disconnect.
