AAD

The m2 AAD has a 15.5-year lifetime, and does not require factory maintenance service during that time.

The unit can be inspected by your rigger annually. Info on that inspection is in the m2 manual at this link and in the photo below.

Still, there are scenarios where an m2 does need to go back to the manufacturer for inspection, repair or service due to an error message, damage to the unit or the like.

Some error codes can be resolved, so first read the manual from this link for more info. ChutingStar also carries common replacement parts for the m2 at this link, which can be installed by your rigger.
