AD/BEECH 35/63 - Wing Forward Spar Carry-Through Structure

Overview

The Civil Aviation Regulations 1998, specifically Part 39, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives which govern the safety standards for aircraft in Australian airspace. One such directive, AD/BEECH 35/63, pertains to Beechcraft 35 (Bonanza) Series Aeroplanes and was enacted to address the identified problem of cracks in the wing forward spar carry-through structure. The directive was issued in response to reports received by the Federal Aviation Administration (FAA) of structural weaknesses in the specified aircraft models. The objective of the directive is to ensure the airworthiness of these aircraft by mandating compliance with the technical requirements outlined in FAA AD 91-14-13 Amdt 39-7054, including necessary inspections and repairs to mitigate the risk of structural failure. The directive applies to Beechcraft 35 Series aeroplanes with certain serial numbers, and compliance is required in accordance with the stipulated requirement document, which includes a revised effective date. The directive ensures that Australian-registered aircraft meet the necessary safety standards, thereby enhancing the overall safety of civil aviation within Australia. The enactment of this legislation by CASA is intended to uphold the safety and integrity of the aviation industry by enforcing stringent airworthiness standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Beechcraft 35 (Bonanza) Series aeroplanes with the specified serial numbers D-4866 through D-10403, including models H35, J35, K35, M35, N35, P35, S35, V35, V35A, and V35B. These aircraft must comply with Airworthiness Directive AD/BEECH 35/63 which mandates inspections, repairs, or reinforcement of the wing forward spar carry-through structure to address reported cracks. This regulatory requirement is applicable to Australian registered aircraft, enforcing compliance with the technical specifications outlined in the FAA AD 91-14-13 Amendment 39-7054. Compliance must be achieved in accordance with the specified Requirement Document, with an effective date of 3 October 1991. The regulation extends its reach to ensure safety standards are met for these particular aircraft types within the national airspace.

Key Provisions

The key provisions of the AD/BEECH 35/63 (section 39-105 of the Civil Aviation Regulations 1998) address the inspection, repair, and reinforcement requirements for the wing forward spar carry-through structure of specific Beechcraft 35 (Bonanza) series aeroplanes. These aeroplanes include models H35, J35, K35, M35, N35, P35, S35, V35, V35A, and V35B with serial numbers ranging from D-4866 through D-10403. The directive mandates compliance with the technical requirements outlined in the Federal Aviation Administration (FAA) AD 91-14-13 Amendment 39-7054. It also notes that Beechcraft Service Bulletin 2360 provides additional details. The directive was revised with an effective date of 3 October 1991 for aircraft registered in Australia. Under the Civil Aviation Regulations 1998, the Act imposes several obligations on the parties or entities it governs. Aircraft owners and operators must ensure that the wing forward spar carry-through structure is inspected in accordance with the specified requirements. This includes both initial inspections and any repetitive inspections as mandated. If any cracks are detected, the affected area must be repaired or reinforced to the standards set forth in the FAA AD 91-14-13 Amendment 39-7054. Failure to adhere to these requirements can result in the aircraft being deemed unairworthy, potentially leading to grounding and other regulatory consequences. The Civil Aviation Regulations 1998 also establish specific offences, penalties, and consequences for non-compliance with the AD/BEECH 35/63 directive. Operators who fail to comply with the mandatory inspections and repair requirements may face civil penalties. These penalties can include fines and other regulatory actions. Additionally, if non-compliance results in an accident or incident, criminal charges could be brought against the responsible parties. The exact penalties for civil and criminal violations are not specified in the AD/BEECH 35/63 directive itself but are governed by the broader provisions of the Civil Aviation Regulations 1998 and related Australian laws.
