The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct an unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Textron Aviation (Beechcraft) 55, 58 and 95-55 (Baron) Series Aeroplanes
AD/BEECH 55/79 Amdt 6  Wing Bolt, Nut and Fitting  11/2024

Applicability:  All models of Textron Aviation (Beechcraft) 55, 58 and 95-55 series aircraft.
Requirement:       1. Remove inspection covers from wing attach fitting recesses and inspect for corrosion or loss of inhibitor. Also inspect drain holes for any blockage that would cause water or debris to accumulate.
                Note 1:  It may be necessary to use a bright light and mirror/magnifying glass to see hard to view areas of the bolt or fittings for signs of corrosion on accessible areas of the bolt. Non accessible areas like the bolt thread encapsulated by the nut will be inhibited, so it is highly unlikely they will experience corrosion unless the general surrounding area is corroded.
                   2. Remove and inspect the wing bolts, washers, nuts and fittings in accordance with Beechcraft Baron Maintenance Manual 55-590000-13 Revision H1, Section 57‑10-00, for model 55 and 58 series; or Baron Maintenance Manual 102‑590000-5 Revision A25, Section 57-00-00, for model 58P and TC series, both as in force on the date of commencement of this AD.
                Note 2:  The bolt torque should be checked before removal for inspection or replacement to confirm the bolt has been torqued to correct value. If the torque value is incorrect, other maintenance action may be required.
                   3. Retire wing bolts, washers and nuts from service and replace with new hardware in accordance with Beechcraft Baron Maintenance Manual 55-590000-13 Revision H1 Section 57-10-00 or Baron Maintenance Manual 102-590000-5 Revision A25 Section 57-00-00 as applicable, both as in force on the date of commencement of this AD. Render unserviceable all hardware retired.
Compliance:     For Requirement 1:
                   Every 12 calendar months 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.

             For Requirement 2:
                  a. For aircraft operating only
