Beechcraft 35 Bonanza — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) of Australia, specifically addressing the Beechcraft 35 Bonanza series aircraft. The directive outlines necessary actions to correct an unsafe condition related to the landing gear up-lock mechanism. It is applicable to various models within the Beechcraft 35 series, including A35, B35, C35, and others, with serial numbers D-1 through D-9287. The directive mandates inspections and potential replacements of components to prevent gear-up landings due to the seizure of up-lock rollers. Compliance with the directive is required within specified timeframes to ensure safety and airworthiness.

• The AD applies to Beechcraft 35 series aircraft with serial numbers D-1 to D-9287.
• Inspect up-lock rollers to determine if they are greasible within 100 hours TIS after the AD's effective date.
• Replace any non-greasible up-lock rollers before further flight.
• Install hollow zerk-ended mounting bolts on the up-lock rollers as part of compliance.
• Lubricate the up-lock mechanism initially within 100 plus/minus 10 hours TIS and thereafter at intervals not exceeding 100 plus/minus 10 hours TIS.
