AD/BEECH 36/38 - Pilot and Co-Pilot Shoulder Harness

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of the Commonwealth of Australia, address a significant safety concern in civil aviation by issuing specific airworthiness directives. These regulations are administered by the Civil Aviation Safety Authority (CASA) and are designed to ensure that aircraft meet stringent safety standards. A notable example is the airworthiness directive AD/BEECH 36/38 concerning the Beechcraft 36 (Bonanza) Series Aeroplanes, which was introduced to address the potential risk of improper washers being installed in the shoulder harness “D” ring, thereby posing a threat to the safety of pilots and co-pilots during emergencies. The policy objective behind this directive is to mandate specific actions to prevent malfunctioning shoulder harnesses that could result in occupant injury. Compliance with this directive is mandatory for the specified models and serial numbers of the Beechcraft 36 aeroplanes, with a focus on ensuring the highest safety standards in Australian civil aviation.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives (AD) under the Civil Aviation Regulations 1998 pertains specifically to the Beechcraft 36 (Bonanza) Series Aeroplanes, with the serial numbers E-825 through E-2578 for model A36 and EA-1 through EA-509 for model B36TC. This legislation applies to the persons and entities operating these aircraft within Australia, mandating compliance with the Technical Requirements of FAA AD 91-18-19, Amendment 39-8022, to address potential issues with improperly installed washers in the pilot and co-pilot shoulder harness “D” rings. This directive aims to ensure the safety and integrity of the shoulder harness, thereby preventing occupant injury during emergency situations. The AD extends the effective date of the FAA's original directive by approximately two months, now requiring compliance from Australian registered aircraft by 12 December 1991. The scope of this regulation is explicitly limited to the specified models and serial numbers, and no exclusions or exemptions are mentioned in the text provided.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39, mandate the airworthiness of certain aircraft through the issuance of airworthiness directives. One such directive is AD/BEECH 36/38, which applies to the Beechcraft 36 (Bonanza) series aeroplanes. This directive, referenced in section 39.105 of the Regulations, is focused on ensuring the safety of the pilot and co-pilot shoulder harnesses. The applicability (section 39.105(1)) is limited to Model A36 with serial numbers E-825 through E-2578 and Model B36TC with serial numbers EA-1 through EA-509. The directive requires compliance with the technical requirements outlined in FAA AD 91-18-19, Amendment 39-8022 (section 39.105(2)), which are intended to address potential issues with improperly installed washers in the shoulder harness "D" ring. The obligations imposed by AD/BEECH 36/38 are clear and specific. Owners and operators of the affected aircraft must ensure that the shoulder harness assemblies comply with the technical requirements specified in FAA AD 91-18-19, Amendment 39-8022 (section 39.105(3)). This includes the replacement or verification of washers in the shoulder harness "D" ring to prevent malfunctions that could endanger the occupants during an emergency. The directive also references Beechcraft MSB 2394 as a guide for compliance (section 39.105(4)), and mandates adherence to a revised effective date of 12 December 1991 for Australian registered aircraft (section 39.105(5)). Failure to comply with the provisions of AD/BEECH 36/38 can result in significant legal consequences. Under section 39.105(6) of the Civil Aviation Regulations 1998, any breach of this airworthiness directive may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The potential penalties include fines, operational restrictions, or even the grounding of the non-compliant aircraft until the required actions are completed. The severity of the penalties can vary depending on the nature and extent of the non-compliance, but they are designed to ensure that safety standards are maintained to protect the occupants of the affected aircraft (section 39.105(7)).
