AD/BEECH 50/4 - Rivets in Firewall Seal Plates

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B03958, address the need for ensuring the airworthiness of specific aircraft models by issuing Airworthiness Directives. This legislation was enacted by the Australian Parliament to fill the gap in regulatory oversight necessary for maintaining safety standards in civil aviation. The policy objective of these regulations is to ensure that aircraft meet specific maintenance and safety criteria, which in this case, concerns the rivets in the firewall seal plates of Beechcraft 50 (Twin Bonanza) Series Aeroplanes with serial numbers CH-1 to CH-98. Compliance with these directives is mandatory and must be undertaken immediately to ensure ongoing airworthiness and safety.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically Part 39 - 105, applies to Beechcraft 50 (Twin Bonanza) Series Aeroplanes with serial numbers ranging from CH-1 to CH-98. The directive mandates compliance with Beechcraft Service Bulletin B50 No. 7 concerning the rivets in the firewall seal plates, requiring immediate action. This regulation operates under the Civil Aviation Regulations 1998, with its applicability extending to the identified model and serial number range of the aircraft. There are no stated exclusions or exemptions within the scope of this directive, and it does not detail any extensions or restrictions through subordinate instruments, indicating that the requirement is to be strictly adhered to for the specified aircraft.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate that owners and operators of Beechcraft 50 (Twin Bonanza) Series Aeroplanes with serial numbers CH-1 to CH-98 must adhere to the Airworthiness Directive AD/BEECH 50/4 concerning the rivets in the firewall seal plates (section 39.105). The directive requires action to be taken in accordance with Beechcraft Service Bulletin B50 - No. 7. Compliance with this directive is mandatory and must be carried out forthwith (section 39.105(1)). The Act imposes specific obligations on the parties governed by it. Owners and operators of the affected aircraft must ensure that the rivets in the firewall seal plates are inspected and repaired or replaced as detailed in Beechcraft Service Bulletin B50 - No. 7. This includes conducting the necessary maintenance actions to address any issues identified during the inspection. It is the responsibility of the aircraft owner or operator to ensure that these requirements are met and that the aircraft remains airworthy (section 39.105(2)). Failure to comply with the Airworthiness Directive AD/BEECH 50/4 can lead to significant consequences. The Act provides for both civil and criminal penalties for non-compliance. Civil penalties may include fines, and in severe cases, the aircraft may be grounded until the required actions are taken. Criminal penalties can also apply, with potential maximum penalties specified under the relevant sections of the Civil Aviation Act 1988. These penalties are intended to enforce compliance and ensure the safety of air travel (section 39.105(3)).
