AD/SM-205/9A - Wing Rear Spar - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, introduced the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives to ensure the safety and airworthiness of aircraft within Australian airspace. This legislative instrument, F2006B07067, was enacted by the Australian Parliament to address specific safety concerns associated with certain aircraft models. The particular focus of this directive is on the SIAI Marchetti S205 and S208 series aeroplanes, mandating inspections and modifications to the wing rear spar to mitigate identified risks and ensure compliance with safety standards. The policy objective of this legislation is to maintain and enhance the safety of civil aviation by enforcing rigorous airworthiness directives. CASA, as the enforcing body, sets these directives to ensure that operators of the specified aircraft models adhere to safety protocols, thereby protecting passengers, crew, and the general public from potential hazards. The directive requires inspections and modifications to be carried out within specific time frames, ensuring that these critical safety measures are implemented without delay.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all SIAI Marchetti S205 and S208 series aeroplanes, encompassing their airworthiness directives for the wing rear spar. These regulations are overseen by the Civil Aviation Safety Authority (CASA) and are applicable nationwide, covering all civil aviation activities within the Commonwealth of Australia. The directives mandate that unless already completed, an inspection of the wing rear spar must be carried out within 25 hours of time in service following 12 February 1976, with subsequent inspections occurring at intervals not exceeding 25 hours of time in service until the modification is made. Additionally, any necessary modifications must be completed within 200 hours of time in service after the same date. The regulations apply to all entities involved in the operation of these aircraft, including aircraft owners, operators, and maintenance personnel, and compliance with these directives is mandatory to ensure the continued airworthiness and safety of the specified aircraft models.

Key Provisions

The key sections of the Civil Aviation Regulations 1998 (sections 39-105) under the Schedule of Airworthiness Directives, specifically pertaining to SIAI Marchetti S205 and S208 series aeroplanes, mandate that inspections and modifications be carried out on the wing rear spar. Section 39-105(2) outlines that all models S.205 and S.208 are subject to these directives. According to the document SIAI Marchetti SB No. 205B42, the aircraft must be inspected within 25 hours of service time after 12 February 1976, and this inspection must be repeated at intervals not exceeding 25 hours of service time until the modification is made. The modification itself must be completed within 200 hours of service time following the same date. The obligations imposed by these regulations on the operators and owners of SIAI Marchetti S205 and S208 aeroplanes include ensuring that the inspections and modifications are performed in accordance with the specified timelines. This requires careful monitoring and scheduling of maintenance activities to ensure compliance with the regulatory requirements. Operators must maintain thorough records of all inspections and modifications conducted, as well as any actions taken in response to findings from these inspections. Failure to comply with the provisions outlined in section 39-105(2) can result in serious consequences. If an operator does not adhere to the mandated inspection and modification schedules, they may be subject to enforcement actions by the Civil Aviation Safety Authority (CASA). Potential outcomes of such non-compliance include fines, penalties, and the possibility of grounding the aircraft until the required work is completed. The exact penalties are not specified in the provided text, but they can be severe, reflecting the critical nature of ensuring the airworthiness of these aircraft.
