COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Airbus Industrie A319, A320 and A321 Series Aeroplanes
AD/A320/82 Wing Rear Spar Pressurised Floor Pick-Up Angles 6/97
Applicability: All models and Serial numbers without Mod. no. 21283 embodied or SB A320-57- 1025 Rev. 2 incorporated.
Requirement: Inspect in accordance with Airbus Industrie SB A320-57-1090, and repair as necessary in accordance with Airbus Industrie SB A320-57-1025 Rev. 2.
Note: DGAC AD 97-084-097(B) refers.
Compliance: Before the accumulation of 20 000 flight cycles, thereafter, at intervals not exceeding 10 000 flight cycles.
Where cracking is detected, repair at the thresholds specified in SB A320-57-1090. This Airworthiness Directive becomes effective on 22 May 1997.
Background: This Directive is raised in order to detect any fatigue cracking in the pressurised floor pick up angles, an unsafe condition that could lead to failure which in turn could affect the structural integrity of the aircraft.
Overview
The Civil Aviation Regulations 1998, specifically within Part 39 - 105, address safety directives for various aircraft types, including the Airbus Industrie A319, A320, and A321 series aeroplanes. This legislation was enacted to ensure that all aircraft maintain airworthiness and safety standards. One particular directive, AD/A320/82, pertains to the wing rear spar pressurised floor pick-up angles, which was introduced to mitigate the risk of fatigue cracking that could compromise the structural integrity of these aircraft. The policy objective, as outlined in the directive, is to ensure regular inspections and necessary repairs to maintain the safety of these aeroplanes. The directive became effective on 22 May 1997 and applies to all models and serial numbers unless specific modifications have been incorporated.
The regulations are enforced by the Civil Aviation Safety Authority (CASA) to ensure compliance with the specified inspection and repair intervals, thereby safeguarding the aviation industry and public safety.
Scope and Application
The Civil Aviation Regulations 1998, under the scope of Part 39 - 105, mandates the application of Airworthiness Directives for specific aircraft types, including Airbus Industrie A319, A320, and A321 series aeroplanes. Specifically, AD/A320/82 pertains to the inspection and repair of wing rear spar pressurised floor pick-up angles for these aircraft models. This directive applies to all models and serial numbers, excluding those with modification number 21283 or those that have incorporated Service Bulletin A320-57-1025 Rev. 2. The directive is designed to address potential fatigue cracking in the specified areas, which could compromise the structural integrity of the aircraft. Compliance with this directive requires inspections in accordance with Airbus Industrie Service Bulletin A320-57-1090 and repairs as necessary, according to Service Bulletin A320-57-1025 Rev. 2. Inspections must occur before the aircraft accumulates 20,000 flight cycles and then at intervals not exceeding 10,000 flight cycles. If cracking is detected, repairs must be conducted as specified in Service Bulletin A320-57-1090. The directive came into effect on 22 May 1997.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directive AD/A320/82 concerning the Airbus Industrie A319, A320, and A321 series aeroplanes. This directive addresses the inspection and repair of the wing rear spar pressurised floor pick-up angles (Section 1). It mandates that inspections and necessary repairs be conducted in accordance with Airbus Industrie Service Bulletins (SB) A320-57-1090 and A320-57-1025 Rev. 2, respectively (Section 2). The directive applies to all models and serial numbers unless modification number 21283 has been incorporated or Service Bulletin A320-57-1025 Rev. 2 has been applied (Section 3).
The obligations imposed by this directive require operators of the specified Airbus aircraft to ensure that the inspections and repairs are conducted before the aeroplane accumulates 20,000 flight cycles and thereafter at intervals not exceeding 10,000 flight cycles (Section 4). This requirement ensures that any potential fatigue cracking in the wing rear spar pressurised floor pick-up angles is detected and addressed promptly to maintain the structural integrity of the aircraft (Section 5). Operators must follow the specific inspection and repair procedures outlined in the referenced Airbus Service Bulletins to comply with this directive (Section 6).
Failure to comply with the requirements of AD/A320/82 could result in serious safety risks, including potential structural failure of the wing rear spar, which could lead to catastrophic outcomes (Section 7). The Civil Aviation Safety Authority (CASA) enforces these regulations, and non-compliance may result in enforcement actions, including fines or other penalties (Section 8). The maximum penalties for breaches of these regulations are not explicitly stated in the directive, but they can be significant under the broader framework of the Civil Aviation Act 1988 and associated regulations (Section 9). Ensuring compliance with this directive is crucial for the continued airworthiness and safety of the aircraft.
