Argus 4 Year Check

In order for an Argus to be considered airworthy, it must have a 4 Year Check within the previous 4 years + 3 months. Unlike other brands, the date of manufacture is not considered in calculating the time for the check.

The unit will be visually inspected, and run through a number of “must fire” and “must not fire” tests. It will be given a fresh set of batteries, and marked with a sticker indicating a year and a check number.

Repairs are not considered part of the check
