AD/BEECH 76/3 - Elevator Trailing Edge Bond

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, represent a comprehensive framework for ensuring the safety and efficiency of civil aviation in Australia. Specifically, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives includes a directive for the Beechcraft 76 (Duchess) Series Aeroplanes, as detailed in AD/BEECH 76/3. This directive, introduced to address the potential safety risk of in-service separation of the elevator trailing edge bond, mandates corrective action in accordance with Beechcraft Service Information No. 1041. The policy objective is to ensure the continued airworthiness of affected aircraft by requiring compliance within 100 hours’ time in service following 30 June 1979, unless such action has already been accomplished. The directive applies to all model 76 with specific serial numbers, thereby aiming to mitigate the identified safety issue and maintain the integrity of these aircraft in operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, applies to all Beechcraft 76 (Duchess) series aeroplanes with specific serial numbers, namely those from ME-1 to ME-6 and ME-8 to ME-62. This regulation is issued under the authority of the Civil Aviation Safety Authority (CASA) and pertains to a directive concerning the elevator trailing edge bond of these aircraft models. The directive mandates compliance with Beechcraft Service Instruction No. 1041 to address the potential in-service separation of the elevator trailing edge bond, which poses a safety concern. The requirement is that the specified action must be undertaken within 100 hours of time in service following 30 June 1979, unless such action has already been completed. This regulation encompasses aircraft within Australia’s jurisdictional scope, ensuring adherence to safety standards set by CASA across the nation.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically address airworthiness directives related to certain aircraft models. Section 39-105 is concerned with the Airworthiness Directives for Beechcraft 76 (Duchess) series aeroplanes, particularly focusing on the elevator trailing edge bond. This section, known as AD/BEECH 76/3, requires compliance with Beechcraft Service Information No. 1041 (paragraph 1(a)). This directive is applicable to all model 76 aircraft with serial numbers ranging from ME-1 to ME-6 and ME-8 to ME-62 (paragraph 1(b)). Entities and individuals responsible for the operation or maintenance of the specified Beechcraft 76 aeroplanes are obligated to ensure that the elevator trailing edge bond is inspected and repaired or replaced as per Beechcraft SI No. 1041. This action must be undertaken within 100 hours of the aircraft being in service after 30 June 1979, unless it has already been completed (paragraph 2(a)). The directive underscores the importance of maintaining the integrity of the elevator trailing edge bond to ensure the safety of the aircraft and its occupants (paragraph 2(b)). Failure to comply with AD/BEECH 76/3 may result in serious safety implications, as there is a risk of in-service separation of the elevator trailing edge bond, which can compromise the aircraft's control and stability. While the Civil Aviation Regulations do not explicitly detail the penalties for non-compliance in this specific section, general provisions within the Civil Aviation Act 1988 may apply. These could include fines and potential prosecution for serious breaches that endanger flight safety, reflecting the high stakes involved in ensuring airworthiness directives are adhered to (paragraph 3).
