AD/SM-205/21 - Landing Gear Cross Members - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide the legal framework for the regulation of civil aviation in the country. Within this extensive body of law, Part 39 focuses on airworthiness directives, which are legally enforceable rules related to the design, production, maintenance, and operation of aircraft. One such directive, AD/SM-205/21, addresses the inspection of landing gear cross members for SIAI Marchetti S205 and S208 series aeroplanes. This directive was introduced to address a specific safety concern related to the structural integrity of the landing gear on these aircraft models, ensuring they remain airworthy. The policy objective of this directive is to mandate regular inspections to prevent potential failures that could compromise safety during landing operations. Compliance with this directive is mandatory for all applicable models, with inspections required within 100 hours of service time after the directive's issuance date of 29 September 1972, and subsequently at intervals not exceeding 100 hours of service time.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, apply to the SIAI Marchetti S205 and S208 series aeroplanes, specifically focusing on the inspection of the landing gear cross members. The legislation mandates that these inspections must be carried out for all models except those equipped with reinforced or newly designed landing gear cross members, as specified in SIAI Marchetti SB No. 205B36. Compliance with this directive requires inspections within 100 hours of time in service after 29 September 1972, and subsequently at intervals not exceeding 100 hours of time in service. This regulation operates under the purview of the Commonwealth of Australia, ensuring that all relevant aircraft within the specified parameters adhere to the stipulated safety standards. The regulations do not specify any exclusions or exemptions, and their application is enforced through subordinate instruments as necessary.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the SIAI Marchetti S205 and S208 Series Aeroplanes. Section AD/SM-205/21 pertains to the landing gear cross members and mandates an inspection protocol for these aircraft models. This directive applies to all models except those equipped with reinforced or newly designed landing gear cross members (Section 9/72). The required compliance document is the SIAI Marchetti SB No. 205B36, which must be adhered to by the operators of these aircraft. Under these regulations, the operators and owners of the specified SIAI Marchetti aircraft models must ensure that inspections of the landing gear cross members are conducted within 100 hours of time in service after 29 September 1972. This initial inspection must be followed by subsequent inspections at intervals not exceeding 100 hours of time in service. These obligations are critical to maintaining the airworthiness of the aircraft and ensuring the safety of all individuals on board. Failure to comply with these airworthiness directives can result in serious consequences. Section 105 of the Civil Aviation Regulations 1998 outlines potential offences and penalties. Infractions of these directives can lead to enforcement actions by CASA, which may include fines, suspension or revocation of the aircraft's certificate of airworthiness, or even criminal charges for those responsible. The maximum penalties for such breaches can be substantial, reflecting the importance of adhering to these safety standards. It is crucial for operators and owners to strictly follow the outlined inspection requirements to avoid these legal and safety repercussions.
