Hexadecimal Code Test?
John T. (Cochise airmotive)
This is a little lawyer-esk, and I am not a lawyer, but reading the AD ...
(g) Repetitive Actions and Corrective Actions requires complying with section 3.4 of the Installation and Operation Manual.
Section 3.4 of the Manual includes, among other things, 3.4.8 Verification of Digital Message. Under that Item, is "Note: This test is not mandatory per FAR 91.207(d) however Ameri-King strongly recommends that it be performed as part of periodic maintenance, at least every year."
I argue that you do not need to verify the digital message to comply with section 3.4 of the manual or, therefore, to meet the requirements of the AD.
