AD/F28/41 - Wing Flap Mechanical Actuators - Modification

Overview

The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B09777, address the need for specific safety directives concerning certain models of Fokker F28 series aeroplanes. Enacted by the Australian Government, these regulations were introduced to ensure that airworthiness directives are strictly followed, particularly for Fokker F28 series aeroplanes with serial numbers within the specified ranges. The policy objective behind these regulations is to maintain the highest safety standards in civil aviation, ensuring the safe operation of aircraft by mandating specific modifications and compliance with outlined safety requirements. The Civil Aviation Regulations 1998, as amended, fall under the jurisdiction of the Civil Aviation Safety Authority (CASA) and are enforced to fill a critical gap in ensuring the airworthiness of Fokker F28 series aeroplanes. The regulations mandate modifications to wing flap mechanical actuators for specific Fokker F28 models, as detailed in the applicable service bulletins and airworthiness directives. Compliance with these directives is crucial to prevent potential safety hazards, thereby protecting passengers, crew, and the general public. The enforcement of these regulations underscores the commitment to aviation safety and the continuous improvement of aviation practices in Australia.

Scope and Application

The Civil Aviation Safety Authority (CASA) regulates the airworthiness of aircraft operating in Australian airspace through the Civil Aviation Regulations 1998, as amended. Specifically, Part 39 - 105 outlines Airworthiness Directives (ADs) that mandate modifications to ensure the continued safe operation of aircraft. One such AD is AD/F28/41, which pertains to Fokker F28 series aeroplanes with specific serial numbers, namely those ranging from 11003 to 11162, 11991, and 11992. This directive mandates modifications to the wing flap mechanical actuators to address safety issues identified in the Fokker or Menasco service bulletins or RLD AD BLA 79-34-27. Compliance with AD/F28/41 is mandatory for the specified aircraft, and operators must follow the detailed requirements outlined in the relevant service bulletins or the authority's directive to ensure the aircraft remain airworthy. The application of this directive is enforced by CASA, which has the authority to issue penalties for non-compliance. The regulation's scope is limited to the specified Fokker F28 series aeroplanes, and it does not extend to other aircraft types or models unless similarly specified by other ADs.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives (ADs) applicable to the Fokker F28 Series Aeroplanes, including AD/F28/41 concerning wing flap mechanical actuators. The directive applies to all models with serial numbers (S/Nos.) ranging from 11003 to 11162, 11991, and 11992. Compliance with this directive is mandated through one of the specified service bulletins or the RLD AD BLA 79-34-27 document, as detailed in the requirement document (Section 39.105). Entities and individuals responsible for maintaining the airworthiness of Fokker F28 Series Aeroplanes within the specified serial number range must ensure that the modifications outlined in the applicable service bulletins or the RLD AD BLA 79-34-27 document are implemented. This includes conducting necessary inspections, repairs, and replacements of wing flap mechanical actuators to meet the safety standards set by CASA. Compliance with these directives is crucial for maintaining the safe operation of these aircraft, as mandated by the Civil Aviation Regulations (Section 39.105). Failure to comply with the airworthiness directives specified in the Civil Aviation Regulations 1998 can result in serious safety risks and potential breaches of aviation safety regulations. Entities and individuals found to be in non-compliance with these directives may face legal consequences, including fines and potential criminal charges under the Civil Aviation Act 1988. The maximum penalties for such breaches can include substantial financial penalties and, in severe cases, imprisonment, highlighting the critical importance of adhering to the stipulated airworthiness requirements (Section 39.105).
