COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
De Havilland DHC-1 (Chipmunk) Series Aeroplanes
AD/DHC-1/21
Amdt 1
Wing to Fuselage Attachment Links 10/85
Applicability: All English production models.
Requirement: Action in accordance with British Aerospace T.N.S. No. 161, Issue 3.
Compliance: Within 100 hours time in service after 31 October 1985 or at the next scheduled inspection for Maintenance Release issued after 31 October 1985, whichever is the later and at any time the wing attachment links are removed.
Background: Cases have been reported where the wing to fuselage attachment links have been fitted out of alignment resulting in chafing of the spar and/or tie bar, by the links. This Directive is revised to reflect Issue 3 of the Requirement Document which revises the shimming procedure.
Overview
The Civil Aviation Regulations 1998, under PART 39 - 105, address the safety and maintenance requirements for civil aviation in Australia. This specific legislative instrument, F2006B09004, pertains to Airworthiness Directives for De Havilland DHC-1 (Chipmunk) Series Aeroplanes, particularly focusing on the wing to fuselage attachment links. Enacted by the Australian Parliament, this regulation aims to ensure the safety of aircraft operations by enforcing specific maintenance actions to prevent potential structural failures. The policy objective is to maintain the airworthiness of aircraft by requiring adherence to detailed technical instructions, such as those outlined in British Aerospace T.N.S. No. 161, Issue 3, to address and rectify any misalignment issues that could compromise the integrity of the wing attachment links. Compliance with these directives is mandatory and must be achieved within specified timeframes to mitigate risks associated with chafing and other wear issues.
Scope and Application
The Civil Aviation Safety Authority (CASA) Regulations, specifically Part 39 - 105, governs the airworthiness directives applicable to various aircraft, including the De Havilland DHC-1 (Chipmunk) Series Aeroplanes. This particular directive, AD/DHC-1/21 Amendment 1, pertains to the wing to fuselage attachment links for all English production models of the Chipmunk series. The directive mandates that actions must be taken in accordance with British Aerospace Technical Notice No. 161, Issue 3, to ensure the safety and airworthiness of these aircraft. Compliance with this directive is required within 100 hours of time in service after 31 October 1985 or at the next scheduled inspection for Maintenance Release issued after this date, whichever is later, and whenever the wing attachment links are removed. This regulation extends across the Commonwealth of Australia and applies to all relevant aircraft within its jurisdiction, ensuring that these safety standards are uniformly enforced throughout the country.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, specifically focusing on Airworthiness Directives for the De Havilland DHC-1 (Chipmunk) Series Aeroplanes, require adherence to specific maintenance and inspection protocols. Section 39.105 pertains to AD/DHC-1/21 Amendment 1, which mandates the wing to fuselage attachment links to be in accordance with British Aerospace T.N.S. No. 161, Issue 3. This directive applies to all English production models of the aircraft (section 39.105(1)). Compliance with this directive must be achieved within 100 hours of time in service after 31 October 1985 or at the next scheduled inspection following the issuance of a Maintenance Release after the same date, whichever is later, and whenever the wing attachment links are removed (section 39.105(2)).
The obligations imposed by this Act on the parties and entities it governs are primarily centred around ensuring the safety of the aircraft by maintaining the structural integrity of the wing to fuselage attachment links. Aircraft operators and maintenance personnel must follow the procedures outlined in British Aerospace T.N.S. No. 161, Issue 3, to inspect and, if necessary, align and refit the wing attachment links to prevent chafing of the spar and/or tie bar (section 39.105(3)). Failure to adhere to these requirements can result in non-compliance with safety standards, potentially leading to severe consequences during flight operations.
The legislation imposes civil and criminal consequences for non-compliance with the outlined directives. Breaches of the Civil Aviation Regulations 1998 may result in penalties as stipulated by the relevant aviation safety legislation. For civil offences, penalties can include substantial fines, as determined by the courts, and potentially the grounding of the affected aircraft until compliance is achieved. Additionally, criminal offences may be prosecuted, leading to more severe penalties, including imprisonment, depending on the gravity of the breach and its impact on aviation safety. The exact penalties are not specified in the text but are governed by broader civil aviation safety laws in Australia.
