AD/BEECH 36/33 Amdt 1 - Pilot and Co-pilot Seat Tracks and Seat Frames

Overview

The Civil Aviation Regulations 1998, as amended through legislative instrument F2006B03888, introduce specific airworthiness directives aimed at ensuring the safety of Beechcraft 36 (Bonanza) series aeroplanes. Enacted by the Commonwealth of Australia, these regulations address the need for enhanced safety measures to prevent failures in the pilot and co-pilot seat attachment during emergency landings. The policy objective is to mandate compliance with specific Beechcraft service bulletins to rectify known structural issues, ensuring that the aircraft meet stringent safety standards. This legislative instrument specifically applies to certain serial numbers of Model A36 and Model A36TC, B36TC aeroplanes, requiring action in accordance with Beechcraft Mandatory Service Bulletin 2010 Revision 1, with specific parts of the bulletin applicable depending on the aircraft model and serial number. Compliance with these directives is mandatory and must be achieved at the next scheduled inspection following 29 December 1988.

Scope and Application

The Civil Aviation Regulations 1998, as outlined in Part 39 - 105, mandate airworthiness directives for specific aircraft models, including the Beechcraft 36 (Bonanza) Series Aeroplanes, which are subject to particular safety directives aimed at preventing mechanical failure during critical phases of flight. Specifically, AD/BEECH 36/33 Amendment 1 addresses the pilot and co-pilot seat tracks and seat frames for certain serial numbers within the Beechcraft 36 series. This directive applies to specific serial number ranges within the models A36 and A36TC, B36TC, necessitating adherence to Beechcraft Mandatory Service Bulletin 2010 Revision 1, with additional compliance options for certain parts of the service bulletin or alternative modifications as per Beechcraft Service Bulletin 2233. Compliance with these directives must be achieved at the next scheduled maintenance inspection following the date of 29 December 1988, ensuring that the aircraft remain airworthy and safe for operation. The regulations are binding across the Commonwealth of Australia and are enforced by the Civil Aviation Safety Authority, with no stated exclusions or exemptions for the specified aircraft models within the stated serial number ranges.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, governs the airworthiness directives for aircraft. The regulation AD/BEECH 36/33 Amendment 1 pertains to the Beechcraft 36 (Bonanza) series aeroplanes, detailing requirements for the pilot and co-pilot seat tracks and seat frames. The applicability section (1) specifies that the directive applies to certain serial numbers of model A36, A36TC, and B36TC aircraft (section 1). The requirements outlined in sections 1 to 3 mandate actions in accordance with Beechcraft Mandatory Service Bulletin (SB) 2010, Revision 1, with specific parts referenced for different serial number ranges (section 2). Notably, compliance with Beechcraft SB 2233 is recognised as an acceptable alternative to the modifications prescribed in SB 2010 Part I (section 3). The obligations under this regulation are clear and specific. Owners or operators of the affected Beechcraft 36 series aeroplanes must ensure that the pilot and co-pilot seat tracks and frames are modified as per the specified service bulletins. This involves either implementing the modifications detailed in SB 2010 Part I and Part II or complying with the alternative modifications outlined in SB 2233, depending on the serial number of the aircraft. These actions must be undertaken at the next scheduled inspection and before a Maintenance Release is issued, following the date of 29 December 1988 (section 4). Failure to comply with these obligations could lead to the aircraft being deemed unairworthy. Failure to adhere to the requirements and timelines set forth in this regulation can result in significant legal consequences. The primary concern is the safety of the aircraft and its occupants, and non-compliance could lead to severe penalties. While the specific penalties are not detailed in the regulation, breaches of airworthiness directives under the Civil Aviation Regulations 1998 can result in civil penalties, including fines and potential criminal charges. In severe cases, the Civil Aviation Safety Authority (CASA) may issue a Notice of Proposed Civil Penalty or take enforcement action against the aircraft operator or owner. The exact penalties would depend on the circumstances of the breach and the discretion of the regulatory authority.
