Overview
The Civil Aviation Regulations 1998, under Part 39 - 105, were enacted to provide comprehensive regulations governing civil aviation safety in Australia, ensuring the safety and efficiency of the national airspace. This particular legislative instrument, F2006B05322, addresses the problem of ensuring the airworthiness of specific models of aeroplanes, specifically the Piaggio P166 Series, through the issuance of Airworthiness Directives (ADs). This directive was introduced to address the safety concerns related to the flap hinge attachment at rib number 13 of the Piaggio P166 Series aeroplanes, which needed regular inspections and, if necessary, modifications to prevent structural failure. The policy objective, as stated within the text, is to mandate inspections and modifications to specific components of the aeroplane to ensure they meet the required safety standards, thus enhancing the overall safety of civil aviation operations in Australia. The enactment of this regulation is a demonstration of the Commonwealth of Australia's commitment to maintaining stringent safety standards within the civil aviation sector.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives pertaining to civil aviation in Australia, including those related to the Piaggio P166 Series Aeroplanes. This particular regulation, AD/P166/29, focuses on the flap hinge attachment at rib number 13 for all models of the Piaggio P166 series prior to serial number 410. It mandates a stringent inspection procedure to detect any cracking in several components, including the attaching plate of the hinge bracket, the web of the dummy spar, the flanges of the joint plate, and the dummy spar post. The requirement is that these inspections must be conducted within the next 100 hours of time in service and at intervals not exceeding 100 hours thereafter until the necessary modifications are made. Additionally, aircraft that have exceeded 2,000 hours of service must comply by a specified deadline, while those with 2,000 hours or less must adhere to the requirement at their first routine inspection following reaching 2,500 hours of service. Failure to comply with these directives can result in significant safety risks, thus underscoring the importance of adherence to these regulations for all relevant aircraft operators within the Commonwealth of Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives for the Piaggio P166 Series Aeroplanes, mandates critical inspections and modifications concerning the flap hinge attachment at rib number 13. Section 5/64 of this directive applies to all models prior to Serial Number 410. The primary requirement (Section 1) is to inspect the flap hinge attachment at rib number 13 for any signs of cracking in several components: the attaching plate of the hinge bracket, the web of the dummy spar, the flanges of the joint plate, and the dummy spar post. This inspection must be carried out as per the guidance provided in Piaggio SL 166-9. If any cracking is identified, the aircraft must be modified in accordance with paragraph 2 before any further flights are undertaken.
The modification process (Section 2) requires adherence to the specifications outlined in Piaggio Service Bulletin No. P166.38. Additionally, the directive references RAI AD 64-26, P166-23, Revision 1, which should be consulted for further details. Compliance with these requirements is crucial to ensure the safety and airworthiness of the aircraft. Specifically, paragraph 1 necessitates that inspections be conducted within the next 100 hours of time in service, and subsequently, at intervals not exceeding 100 hours time in service until modifications are completed. Paragraph 2 stipulates that for aircraft that have already accumulated over 2,000 hours of time in service, compliance must be achieved by 1 November 1964. For aircraft with 2,000 hours or less of time in service, compliance must be met at the first routine inspection following the aircraft reaching 2,500 hours of time in service.
Failure to comply with the requirements of this directive can result in significant legal and operational consequences. The Civil Aviation Regulations 1998 impose obligations on aircraft operators and maintenance personnel to adhere to these airworthiness directives to ensure the safety of flight operations. Breaches of these obligations may lead to enforcement actions, including fines and penalties. The specific consequences for non-compliance are not detailed in the provided text, but typically, such breaches can lead to substantial financial penalties and potential grounding of the aircraft until the required modifications are completed. The severity of the penalties may depend on the degree of non-compliance and any resultant safety risks.
