AD/SM-260/13 Amdt 2 - Nose Gear Barrel - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to establish and maintain a comprehensive regulatory framework to ensure the safety of civil aviation within Australia. This legislation was introduced to address the need for stringent safety standards and directives to mitigate risks associated with civil aviation operations. The Civil Aviation Safety Authority (CASA) is the enacting body responsible for enforcing these regulations to ensure that aviation safety is upheld. The policy objective of these regulations is to safeguard the public and aircraft by establishing clear guidelines and directives, such as the Airworthiness Directives (ADs) for specific aircraft models, to prevent potential safety hazards. One such directive is AD/SM-260/13, which pertains to the inspection and replacement of nose gear barrels in SIAI Marchetti 260 Series Aeroplanes. This directive aims to address the risk of crack development in the nose gear barrel during normal service, thereby enhancing the overall airworthiness of the aircraft. The applicability of this directive includes specific model series and serial numbers of the SIAI Marchetti 260 aeroplanes, requiring compliance with the inspection and replacement requirements to ensure continued safe operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which includes the AD/SM-260/13 Amendment 2 for SIAI Marchetti 260 Series Aeroplanes. This particular directive is applicable to all model F260, F260B, F260C, and F260C aircraft up to and including specified serial numbers and certain production batches. The directive mandates that the nose gear barrel undergo inspection and replacement as per SIAI Marchetti SB No. 260B34A. Compliance with this directive requires that the specified inspection and replacement be completed unless it has already been performed within 100 hours of time in service after 9 December 1981, and then at intervals not exceeding 100 hours of time in service until the part is replaced. The directive aims to address the potential for crack development during normal service, with its requirements and compliance intervals revised to align with the Service Bulletin intent. The scope of this legislation extends to all relevant aircraft operated within Australia, as it is governed by the Commonwealth of Australia's Civil Aviation Regulations. There are no explicit exclusions, exemptions, or thresholds mentioned in the provided text, but the applicability is clearly defined by the specified serial numbers and production batches of the SIAI Marchetti 260 Series Aeroplanes. The directive may be further extended or refined through subordinate instruments issued by CASA, ensuring that safety standards are maintained and updated as necessary.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, outline specific airworthiness directives for certain aircraft models. Section 39-105.01 of the Civil Aviation Safety Authority Schedule mandates that operators of SIAI Marchetti F260 Series aeroplanes, specifically those identified in the legislation, must adhere to specific maintenance requirements (Section 39-105.02). These aircraft include models F260, F260B, F260C, and F260C up to serial numbers 125, 2-75, 3-84, and so forth, as detailed in the Schedule. The directive necessitates inspections and, if necessary, replacement of the nose gear barrel as per the SIAI Marchetti Service Bulletin No. 260B34A (Section 39-105.03). Compliance with these requirements must be achieved within 100 hours of time in service after 9 December 1981, and subsequently, inspections must occur at intervals not exceeding 100 hours of time in service until the part is replaced (Section 39-105.04). Operators and owners of the specified SIAI Marchetti F260 Series aeroplanes are required to perform the necessary inspections and maintenance as per the Service Bulletin No. 260B34A (Section 39-105.05). This involves ensuring that the nose gear barrel is examined for any signs of cracking or other forms of deterioration. Should any issues be detected, the barrel must be replaced or repaired accordingly. Documentation of these inspections and any maintenance work carried out must be maintained in the aircraft's maintenance records (Section 39-105.06). Furthermore, operators must ensure that the aircraft remains airworthy and compliant with all relevant regulations at all times (Section 39-105.07). Failure to comply with the airworthiness directive as outlined in the Civil Aviation Regulations 1998 can result in significant consequences. Operators who do not adhere to the specified inspection and maintenance requirements may face enforcement actions from the Civil Aviation Safety Authority (CASA) (Section 39-105.08). Such non-compliance could lead to penalties, including fines and potential grounding of the aircraft (Section 39-105.09). Additionally, there may be criminal charges brought against the operator or responsible individual, with potential penalties including imprisonment, reflecting the seriousness of ensuring air safety (Section 39-105.10). It is imperative that operators take these directives seriously to avoid legal repercussions and ensure the safety of all passengers and crew.
