AD/F28/9 - Flap Vane Drive Mechanism - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form the backbone of aviation safety regulations in the country. Specifically, Part 39 of these regulations addresses the authority and procedures for issuing Airworthiness Directives (ADs) to ensure that aircraft are maintained in a safe condition. The AD/F28/9, which pertains to the Fokker F28 Series Aeroplanes and specifically mandates an inspection of the flap vane drive mechanism for certain serial numbers, was introduced to address safety concerns identified with the aircraft model. This particular directive aims to ensure that these aeroplanes meet the required safety standards before a specified compliance date. The Civil Aviation Safety Authority (CASA), which is responsible for enforcing these regulations, has identified a need for regular inspections to prevent potential failures in the flap vane drive mechanism that could compromise flight safety. The overarching policy objective is to maintain the highest standards of airworthiness and public safety in Australian aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, apply to Fokker F28 Series aeroplanes with serial numbers ranging from 11003 to 11026 and 11991. This legislation mandates that all affected aircraft undergo an inspection of their flap vane drive mechanism, as detailed in Fokker Service Bulletin F28/27-41. This directive ensures that the aircraft meet the necessary safety standards before any subsequent flight following the compliance date, which is set before 31 March 1971. The regulations extend to all operators and owners of these specific Fokker F28 models, ensuring that the inspection is performed by certified personnel in compliance with the outlined procedures. The geographic reach of these regulations is national, applying to all aircraft registered and operating within Australia, with no stated exclusions or exemptions. Compliance is critical, as failure to adhere to these airworthiness directives could result in the aircraft being grounded until the required inspections are completed satisfactorily.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (ADs) that are critical for maintaining the safety standards of aircraft in Australian airspace. Among these, AD/F28/9 pertains to Fokker F28 series aeroplanes, focusing on the flap vane drive mechanism (section 1). This directive applies to all models with serial numbers ranging from 11003 to 11026 and 11991, and it mandates compliance before 31 March 1971 as detailed in Fokker Service Bulletin F28/27-41 (section 2). The directive requires an inspection of the flap vane drive mechanism to ensure it meets the specified airworthiness standards. Operators and owners of the affected Fokker F28 series aeroplanes must adhere to the requirements set out in AD/F28/9. This involves conducting a thorough inspection of the flap vane drive mechanism as per the guidelines provided in Fokker Service Bulletin F28/27-41. The inspection is necessary to identify and rectify any issues that could compromise the safety of the aircraft, ensuring that the aeroplane remains airworthy and compliant with aviation safety standards. Failure to comply with these requirements could lead to serious consequences, including the grounding of the aircraft until the necessary inspections and repairs are completed. Failure to comply with AD/F28/9 can result in various civil and criminal consequences. Non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA), which could include fines, legal proceedings, or other penalties. The exact penalties are not specified in the directive but are generally aligned with the severity of the non-compliance and its potential impact on aviation safety. In the most severe cases, significant non-compliance could result in criminal charges, leading to substantial fines and imprisonment for the responsible parties. Additionally, ongoing non-compliance could result in the suspension or revocation of the aircraft's airworthiness certificate, preventing it from operating in Australian airspace. This not only affects the operator's ability to conduct flights but also carries reputational risks and financial losses. It is crucial for operators and owners to take AD/F28/9 seriously and ensure all required inspections are performed in a timely manner to avoid these adverse outcomes.
