Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to address the safety and operational standards within the aviation sector in Australia. This legislation was introduced to ensure the highest safety standards and to prevent accidents related to aircraft maintenance and operational issues. The Civil Aviation Safety Authority, as the responsible body, developed these regulations under the authority granted by the Civil Aviation Act 1988. The policy objective is to mitigate risks associated with aircraft operations by mandating specific maintenance and inspection protocols. One such protocol is the Airworthiness Directive AD/SM-260/16 concerning the SIAI Marchetti 260 Series Aeroplanes, which requires inspections of the wing main spar web to prevent structural failures.
This specific Airworthiness Directive was issued to address the identified risk of cracks in the wing main spar web of SIAI Marchetti 260 Series aeroplanes. The directive mandates a series of inspections and maintenance actions to ensure the continued airworthiness of these aircraft. The inspections are scheduled based on the aircraft's time in service, with varying intervals for aircraft that have accumulated different levels of flight hours. Compliance with these requirements is crucial to maintaining the safety and reliability of the aircraft within the Australian aviation sector.
Scope and Application
The Civil Aviation Safety Authority (CASA) issued the Airworthiness Directive AD/SM-260/16 for the SIAI Marchetti 260 Series Aeroplanes, specifically targeting model F260, F260B, F260C, and F260D with Serial Numbers up to and including 735. The directive mandates an inspection for cracks in the wing main spar web, in accordance with SIAI Marchetti Service Bulletin No. 260-B50, and references RAI AD 86-199/F260-32. The directive applies to aircraft based on their time in service as of 4 June 1987, with varying timeframes for the initial inspection depending on the number of hours the aircraft has accumulated. Compliance requires repeat inspections at intervals not exceeding 500 hours time in service until the aircraft is modified as per the requirement document. This directive is part of the Civil Aviation Regulations 1998 and carries the full jurisdictional reach of the Commonwealth of Australia, applying to all relevant aircraft registered within Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, contains an important directive for the SIAI Marchetti 260 Series aeroplanes, referenced as AD/SM-260/16. This directive pertains to the wing main spar web and applies to all model F260, F260B, F260C, and F260D aeroplanes with serial numbers up to and including 735. The directive mandates actions in accordance with SIAI Marchetti Service Bulletin No. 260-B50, referencing RAI AD 86-199/F260-32.
Under this directive, there are clear timelines and conditions for the initial inspection. For aircraft with less than 1000 hours of service as of 4 June 1987, the inspection must occur either before the aircraft exceeds 1000 hours of service or within 500 hours after 4 June 1987, whichever is later. For those with between 1000 and 3000 hours of service as of that date, the inspection must take place within 500 hours after 4 June 1987 or before the aircraft reaches 3100 hours of service, whichever comes first. Aircraft with 3000 or more hours of service as of 4 June 1987 must undergo the inspection within 100 hours of that date. Following the initial inspection, subsequent inspections must occur at intervals not exceeding 500 hours until the aircraft is modified according to the requirements outlined in the directive.
The directive imposes specific obligations on the operators and owners of the affected aircraft. They must ensure that the initial inspection is conducted as per the prescribed timelines and conditions. Furthermore, they must schedule repeat inspections at intervals not exceeding 500 hours of service until the required modifications are implemented. Failure to comply with these inspection requirements can result in severe consequences. The Civil Aviation Regulations 1998 provide for penalties for non-compliance, which may include fines and other sanctions, as detailed in the broader regulatory framework. Non-compliance can also lead to grounding of the aircraft, thereby affecting the operational capabilities of the operator.
