AD/SM-205/37 - Flap Cable Pulley Brackets

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, includes the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, specifically AD/SM-205/37 for the SIAI Marchetti S205 and S208 series aeroplanes. Enacted to address the problem of flap cable failure due to misalignment of the pulley brackets, this directive is a legislative instrument that mandates the replacement and inspection of flap cable pulley brackets and pulleys as per SIAI Marchetti Service Bulletin 205B60. The directive requires compliance within 100 hours of time in service after 7 December 1995 or at the next inspection for issue of a Maintenance Release, whichever occurs first. This regulation is issued by the Civil Aviation Safety Authority, aiming to enhance aviation safety by ensuring the structural integrity of the specified aircraft models. This Airworthiness Directive responds to a reported case of flap cable failure by the Italian airworthiness authority, which was attributed to the misalignment of the pulley brackets. The directive outlines the necessity for replacing certain pulley brackets with improved ones and conducting inspections of other brackets and pulleys for proper alignment and wear, thereby preventing potential safety hazards. The policy objective is to maintain the highest standards of airworthiness and ensure the safety of aircraft operations in accordance with international and domestic aviation regulations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a Schedule of Airworthiness Directives which governs the maintenance and operation of aircraft within Australia. Under this legislation, AD/SM-205/37 pertains to the SIAI Marchetti S205 and S208 series aeroplanes, mandating the replacement and inspection of flap cable pulley brackets. This directive applies to the S205, S208, and S208A models of the aircraft, requiring compliance with SIAI Marchetti Service Bulletin 205B60. Compliance must be achieved either at the next inspection for the issue of a Maintenance Release or within 100 hours of time in service after 7 December 1995, whichever comes first. This directive arises from a reported incident of flap cable failure due to the misalignment of the pulley brackets, as documented by the Italian airworthiness authority. The directive ensures that these aircraft maintain safe operational standards by requiring the replacement of specific components and inspecting others for alignment and wear. The regulations are enforced by the Civil Aviation Safety Authority and have a national jurisdictional reach across Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/SM-205/37, pertains to SIAI Marchetti S205 and S208 series aeroplanes and addresses the replacement and inspection of flap cable pulley brackets. This directive, issued on 13/95, applies to models S205, S208, and S208A aircraft. According to section 1 of the AD, the requirement is to replace and inspect the flap cable pulley brackets and pulleys as per the SIAI Marchetti Service Bulletin 205B60. This is to ensure the aircraft's safety following a reported case of flap cable failure due to misalignment of the pulley brackets by the Italian airworthiness authority. The AD references RAI AD 95-237 for further information. The AD imposes specific obligations on the operators of SIAI Marchetti S205 and S208 series aircraft. Operators must ensure that the replacement and inspection of the flap cable pulley brackets and pulleys are carried out in accordance with the requirements outlined in the directive. This includes adhering to the guidelines set forth in the SIAI Marchetti Service Bulletin 205B60. Compliance with these requirements is necessary at the next inspection for the issuance of a Maintenance Release or within 100 hours of time in service after 7 December 1995, whichever comes first. This ensures that the necessary safety measures are implemented promptly to prevent any potential flap cable failures. Failure to comply with the provisions of the AD may result in civil or criminal consequences. While the specific penalties are not detailed within the text of the AD, breaches of the Civil Aviation Regulations 1998 can lead to enforcement actions by CASA. Potential penalties may include fines, suspension or revocation of the aircraft's Certificate of Airworthiness, or other regulatory measures. It is crucial for operators to adhere to the requirements of the AD to avoid any legal or safety repercussions. Ensuring compliance with the AD is essential for maintaining the airworthiness of SIAI Marchetti S205 and S208 series aircraft and preventing any potential flap cable failures.
