Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to ensure the safe operation of aircraft by establishing and enforcing airworthiness standards. This legislative instrument, known as F2006B11329, addresses the specific issue of ensuring the structural integrity of Aerospatiale Rallye series aeroplanes, particularly focusing on the spot welding of the skin to the rear fuselage frame. The problem it seeks to resolve is the potential risk of structural failure due to insufficient or degraded welds, which could compromise the safety of the aircraft in operation. This instrument was enacted by the Australian Parliament, aiming to uphold the overarching policy objective of maintaining high standards of aviation safety by mandating regular inspections and compliance with specified maintenance schedules. The directive applies to all Aerospatiale Rallye series aeroplanes with serial numbers ranging from 1 to 80, requiring inspections to be conducted at intervals not exceeding 100 hours of time in service.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Aerospatiale Rallye Series aeroplanes with serial numbers from 1 to 80, establishing requirements for their airworthiness. This regulation mandates that inspections of spot welding of the skin to the rear fuselage frame must be conducted at intervals not exceeding 100 hours of time in service. Compliance with these directives is ensured through the provision of Rallye Service Bulletin No. 6 or MS Modification No. 17. The regulation is applicable across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority, ensuring that the specified maintenance practices are uniformly applied to uphold the safety standards of these aircraft within the national jurisdiction.
Key Provisions
The Civil Aviation Regulations 1998, specifically within Part 39 - 105, contains the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, including the AD/MSR/3 concerning the spot welding of the skin to the rear fuselage frame on Aerospatiale Rallye Series Aeroplanes. This directive applies to all Rallye models with serial numbers (S/Nos.) 1 to 80. To comply with this directive, operators must adhere to the instructions provided in either Rallye Service Bulletin No. 6 or Maintenance Supplement Modification No. 17. The requirement is for inspections to be conducted at intervals not exceeding 100 hours of time in service.
Operators of the Aerospatiale Rallye Series Aeroplanes covered by this directive are obligated to ensure that the spot welding of the skin to the rear fuselage frame is inspected according to the specified documentation and intervals. This involves a detailed review and possible repair or replacement of welds to maintain the structural integrity and airworthiness of the aircraft. Operators must keep detailed records of all inspections and any actions taken as a result of these inspections, ensuring that all maintenance and safety standards are consistently met.
Failure to comply with the provisions of AD/MSR/3 may result in serious consequences. The Civil Aviation Regulations 1998 do not explicitly detail the penalties for non-compliance within this specific directive, but generally, non-compliance with CASA directives can lead to enforcement actions, fines, or other regulatory measures. In severe cases, non-compliance could potentially result in the grounding of the aircraft until the necessary inspections and repairs are completed, thereby affecting the operational readiness and safety of the aircraft.
