Overview

The Civil Aviation Regulations 1998, amended in 2006, include specific directives to ensure the safety and airworthiness of aircraft operating in Australia. One such directive is the Airworthiness Directive AD/SM-260/15, which pertains to SIAI Marchetti 260 Series aeroplanes. This directive was introduced to address the potential safety issue of fuel flow obstruction caused by movement of the tip tank fuel tubes in certain SIAI Marchetti aeroplanes. The directive mandates an inspection and, if necessary, the replacement of wing tip fuel tank components to ensure they are securely welded to their supports. The objective of this directive is to maintain the integrity of the fuel system and prevent any potential hazards that could compromise the safety of the aircraft. This directive is issued by the Civil Aviation Safety Authority and is intended to ensure compliance with airworthiness standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the scope and application of the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, including AD/SM-260/15 concerning SIAI Marchetti 260 Series Aeroplanes. This legislation applies to all model F260, F260B, and F260C aeroplanes with specific serial numbers detailed in the Requirement Document. The directive mandates an inspection and, if necessary, replacement of wing tip fuel tank components to prevent fuel flow obstruction due to the movement of the tip tank fuel tubes. Compliance is required within 25 hours of time in service after 31 October 1984. The directive is geographically applicable across the Commonwealth of Australia, extending CASA’s regulatory reach to ensure the airworthiness of these specific aircraft models. The directive does not explicitly exclude any entities or persons from its application, and the compliance is mandatory for the specified aircraft within the stipulated timeframe. Subordinate instruments may further detail the inspection and compliance procedures as necessary.

Key Provisions

The Civil Aviation Regulations 1998, particularly under PART 39 - 105, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. Specifically, AD/SM-260/15 pertains to SIAI Marchetti 260 Series Aeroplanes, focusing on the wing tip fuel tank components. This directive applies to all model F260, F260B, and F260C with specific serial numbers detailed in the Requirement Document. The key requirement (section 260B39.10/84) is to ensure that the wing tip fuel tank components are inspected to prevent fuel flow obstruction caused by movement of the tip tank fuel tubes. This inspection must be conducted to ensure the tubes are securely welded to their supports. The compliance mandate (section 260B39.10/84) specifies that this inspection must be carried out within 25 hours of time in service after 31 October 1984. Operators and owners of SIAI Marchetti 260 Series Aeroplanes must adhere to these regulations by conducting the required inspections of the wing tip fuel tank components. The inspection must be thorough and ensure that the fuel tubes are properly welded to their supports, thus preventing any obstruction of fuel flow. This is a critical safety measure to maintain the airworthiness of the aircraft. The requirement to perform these inspections within the specified timeframe is also an essential obligation, underscoring the importance of timely compliance with air safety standards. Failure to comply with these airworthiness directives can result in serious consequences. The legislation does not explicitly state the penalties for non-compliance, but non-compliance with airworthiness directives generally can lead to severe repercussions, including fines, aircraft grounding, or even revocation of airworthiness certificates. Such actions can significantly impact the operations of the airline or aircraft operator, potentially leading to substantial financial losses and reputational damage. Additionally, non-compliance can pose significant safety risks, leading to potential accidents and endangering lives. Therefore, adhering to these directives is not just a regulatory requirement but a critical safety imperative.
