AD/BEECH 55/67 Amdt 1 - Fuselage Seat Attachment Brackets

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, introduced Airworthiness Directives to ensure the safety and airworthiness of aircraft within Australia. One such directive is AD/BEECH 55/67 Amendment 1, which pertains to Beechcraft 55, 58 and 95-55 (Baron) Series Aeroplanes. This amendment was enacted to address issues related to the fuselage seat attachment brackets, particularly for models 58P and 58PA with serial numbers between TJ-3 to TJ-435 and TJ-437 to TJ-443. The primary problem this directive aimed to resolve was to enhance the impact capability of the fifth and sixth seat attachment to better protect passengers. The policy objective is to mandate specific modifications and placarding to ensure compliance with safety standards, as outlined by Beechcraft Service Bulletin No. 2022, and in reference to the Federal Aviation Administration's AD 85-11-04. Compliance with these directives is crucial to maintain the airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety directives applicable to Beechcraft 55, 58 and 95-55 (Baron) Series aeroplanes. This regulation mandates particular actions for enhancing the airworthiness of these aircraft, focusing on the fuselage seat attachment brackets. It applies to all models 58P and 58PA with specific serial numbers, mandating the fabrication and installation of a temporary placard to warn against occupying seats 5 or 6 during take-off or landing, as well as modifications in line with Beechcraft Service Bulletin No. 2022. This directive is intended to ensure passenger safety by improving the impact capability of the 5th and 6th seat attachment during critical phases of flight. Compliance with these directives must be achieved within specified timeframes post the directive's issuance date of 1 July 1985. The regulation's scope is confined to the mentioned aircraft models and serial numbers, and it does not explicitly provide for extensions or restrictions through subordinate instruments, but rather sets out clear compliance deadlines.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a schedule of airworthiness directives pertaining to certain models of Beechcraft aeroplanes. In the context of the Beechcraft 55, 58, and 95-55 (Baron) Series Aeroplanes, AD/BEECH 55/67 Amendment 1 addresses the fuselage seat attachment brackets. According to the directive (section 1), operators of all models 58P and 58PA with specific serial numbers must adhere to certain requirements to ensure airworthiness and passenger safety. The key requirements of this directive include the fabrication and installation of a temporary placard in full view of the pilot, using letters of a minimum height of 3mm. The placard must state "DO NOT OCCUPY SEATS 5 OR 6 DURING TAKEOFF OR LANDING" (section 1.1). Additionally, the operators must modify the aircraft in accordance with Beechcraft Service Bulletin No. 2022, as referenced in FAA AD 85-11-04 (section 1.2). Compliance with these requirements must be achieved within specific timeframes: within 25 hours’ time in service after 1 July 1985, or within 100 hours’ time in service after 1 July 1985, or at the next scheduled inspection for Maintenance Release issue after 1 July 1985, whichever is the later (section 2). Operators of the affected Beechcraft aeroplanes are obligated to ensure that the required modifications and placarding are completed within the specified timeframes to maintain compliance with the Civil Aviation Regulations. Failure to comply with these airworthiness directives could result in serious safety implications, as the directive was issued to improve the impact capability of the 5th and 6th seat attachments for passenger protection. Non-compliance could potentially lead to severe consequences during critical phases of flight such as takeoff and landing. In terms of legal consequences, the Civil Aviation Regulations do not explicitly state penalties for non-compliance with airworthiness directives. However, the Civil Aviation Safety Authority (CASA) has the authority to take action against operators who fail to comply with these directives. Such actions may include the issuance of a Notice of Proposed Civil Penalty, enforcement actions, or in severe cases, grounding of the aircraft. The potential penalties could include fines, suspension of air operator certificates, or other regulatory actions deemed necessary to enforce compliance and ensure safety standards are met.
