2 Duration

This instrument:

(a) commences on the day after it is registered; and

3 Alternate means of compliance for private operations aircraft

(1) The following means of compliance with the AD other than that set out in the AD is approved for a relevant aircraft:

(a) for an inspection due on or before 12 March 2024 under Requirement 2 in the AD, completion of the inspection by not later than 12 April 2024;

(b) instead of the magnetic particle inspection required under Requirement 2 of the AD, removal of the wing bolts and performance of a detailed visual inspection of each wing bolt using a 10-power or stronger magnifying glass for corrosion, cracks, and mechanical damage and replacement of any wing bolt that is corroded, cracked or has mechanical damage;

Note 1 A magnetic particle inspection is required under both the Beechcraft Baron Shop Manual and Baron Maintenance Manual, as described in the AD, that are adopted by reference by Requirement 2 of the AD.

Note 2 The cadmium plating of a wing bolt may display areas that appear rubbed, discoloured, or polished. These areas are usually the result of prevailing installation procedures and are of no significance. A wing bolt should not be rejected because of cadmium plating deterioration.

(c) the increase of the compliance time for Requirement 3 in the AD from 15 years to 20 years after the first installation of a new zero-time wing bolt.

Note All other requirements and compliance times stated in the AD remain unchanged.

(2) In this section:

relevant aircraft means an aircraft to which the AD applies that is operated only in private operations.
