Textron Aviation (Beechcraft) 35 (Bonanza) Series Aeroplanes AD/BEECH 35/67 Amdt 5 Wing Bolt, Nut and Fitting 11/2024

Applicability: All models of Textron Aviation (formerly Beechcraft) 35 series aeroplanes, all serial numbers. 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 wing bolts, washers, nuts and fittings in accordance with Beechcraft Maintenance Manual 36-590001-9 Revision D1 Chapter 57, 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. Note 3: Amendment 5 of this AD makes reference to all serial numbers within the applicability as the Type Certificate holder has not updated the Beechcraft Shop manuals which includes other serial number ranges. The maintenance manual listed above at revision D1 is to be utilised for all serial numbers with reference to the wing bolt, nut and fitting requirements. 3. Retire wing bolts, washers and nuts from service and replace with new hardware in accordance with Beechcraft Maintenance Manual 36-590001-9 Revision D1 Chapter 57, 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.
