AD/BEECH 36/13 - Flap Bracket

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted by the Commonwealth of Australia to ensure the safety of civil aviation within its jurisdiction. Within this framework, the legislation includes the Airworthiness Directive AD/BEECH 36/13 concerning Beechcraft 36 (Bonanza) Series Aeroplanes. This directive was introduced to address potential structural integrity issues with the flap actuator brackets on these aircraft, particularly after they have accumulated a significant amount of operational time. The problem it aims to resolve is the risk of cracks or signs of distress in the flap actuator brackets and adjacent structures, which could compromise the aircraft's safety. The policy objective, as stated in the regulations, is to mandate regular inspections of the specified components to prevent structural failures that could result in catastrophic outcomes. The Civil Aviation Safety Authority, as the enforcing body, requires that inspections be carried out within 100 hours of time in service after a specified date and at intervals not exceeding 300 hours thereafter, ensuring ongoing compliance with safety standards. This directive underscores the commitment to maintaining high safety standards in civil aviation operations.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 mandates specific airworthiness directives for aircraft to ensure safety and compliance within the Australian aviation industry. One such directive, AD/BEECH 36/13, applies to all models of Beechcraft 36 (Bonanza) series aeroplanes that have accrued 1000 or more hours of time in service. This requirement mandates that the flap actuator bracket and the adjacent structure on both the left-hand and right-hand flaps must be inspected for any cracks or signs of distress. Compliance with this directive is necessary within 100 hours of time in service following 31 August 1972, and subsequently, inspections must occur at intervals not exceeding 300 hours of time in service. The directive sets forth a clear scope and application, ensuring that these critical inspections are performed regularly to maintain the safety standards of the aircraft.

Key Provisions

The key provisions of AD/BEECH 36/13 under the Civil Aviation Regulations 1998 require specific maintenance actions to be taken for Beechcraft 36 (Bonanza) Series Aeroplanes. Section 105 of PART 39 outlines the applicability and requirements of these Airworthiness Directives (AD). Specifically, AD/BEECH 36/13 applies to all models of the Beechcraft 36 Series that have accumulated 1000 or more hours of time in service (Section 105.03). The directive mandates that the flap actuator bracket and the adjacent structure on both the left-hand (LH) and right-hand (RH) flaps must be inspected for any cracks or signs of distress (Section 105.04). The obligations imposed by AD/BEECH 36/13 include conducting the required inspections within 100 hours of time in service after 31 August 1972, and then at intervals not exceeding 300 hours of time in service thereafter (Section 105.05). These inspections are critical to ensure the continued airworthiness and safety of the aircraft. The regulations mandate that these checks must be carried out by qualified personnel who are competent to perform such inspections and to identify any structural issues that could compromise the safety of the aeroplane. Failure to comply with the AD/BEECH 36/13 provisions can lead to significant consequences. While the Civil Aviation Regulations do not explicitly state penalties for non-compliance with specific ADs, general non-compliance with aviation safety regulations can result in serious legal ramifications. This may include fines, revocation of airworthiness certificates, or even criminal charges in cases where negligence leads to accidents or safety incidents. It is important for operators and maintenance personnel to adhere strictly to these directives to avoid any legal or safety issues.
