for all aircraft. If visible corrosion is found within the recess or on visible portion of the bolt or nuts, washers or fittings, then Requirement 2 must be accomplished before further flight.

                  a. For aircraft operating only in private operations:
                     i. unless the inspection has already been accomplished in accordance with either of the requirement documents within 10 years from the installation of the wing bolts, inspect within 100 hours' time in service (TIS) or 12 months from the commencement date of this AD, whichever occurs first.
                  Note 3:  Installation of the wing bolts includes where they are removed for inspection purposes and re-installed.
                     ii. re-inspect at intervals not to exceed 10 years from the previous inspection.
                  b. For all other operational categories,
                     i. unless the inspection has already been accomplished in accordance with either of the requirement documents within 5 years from the installation of the wing bolts, inspect within 100 hours' time in service (TIS) or 12 months from the commencement date of this AD, whichever occurs first.
                  Note 4:  Installation of the wing bolts includes where they are removed for inspection purposes and re-installed.
                     ii. re-inspect at intervals not to exceed 5 years from the previous inspection.
             For Requirement 3:
                   1. For models 55 and 58 series aeroplanes - Before 20 years TIS after the first installation of new zero time wing bolts.
                  b. For models 58P and 58TC series aeroplanes - Before 15 years TIS after the first installation of new zero time wing bolts.
             Mandatory reporting requirements:
             Both NIL findings of defects and confirmed defects for Requirement 2 inspection must be reported to CASA.
             This AD commences on 30 May 2024.
Background:  The initial issue of this Airworthiness Directive became effective on 1 February 1996 and made mandatory the inspection and replacement periods for the wing attachment hardware as detailed in the requirement document.
             Amendment 1 of this AD updated the revision status of the Beech 55 Shop Manual.
             Amendment 2 of this AD added the Note to Requirement 2 and added the fittings as an item to be inspected when the wing bolts, washers and nuts are removed and inspected.
             Amendment 3 removed the alternative means of compliance that had been issued to allow in-situ inspection of the wing attachment bolts and nuts rather than conduct the manufacturer's required MPI.
             Amendment 4 of this AD was issued to extend the compliance time for Requirement 1 by two months whilst the proposed airworthiness directive process was conducted for AD/BEECH 55/79 Amdt 5.
             Amendment 5 of this AD allowed for aircraft used in private operations to be visually inspected for corrosion in the exposed areas of the wing attach bolts and wing fitting
