AD/F27/125 Amdt 3 - Corrosion Prevention and Control

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives, and within this framework, there exists the Fokker F27 Series Aeroplanes AD/F27/125 Amendment 3 concerning corrosion prevention and control. This legislative instrument was enacted to address the need for a structured approach to managing and mitigating corrosion within the Fokker F27 series aircraft, excluding the Mk 050 series. The Civil Aviation Safety Authority (CASA) mandates adherence to these regulations to ensure that corrosion does not compromise the structural integrity of these aircraft. The underlying policy objective is to maintain high safety standards in civil aviation by requiring specific reporting and corrective actions for identified corrosion levels, thereby ensuring that any potential risks are promptly identified and addressed. The regulations outline a tiered approach to corrosion reporting, with level 1 corrosion not requiring any report, level 2 corrosion needing a consolidated report within sixty days of corrective action, and level 3 corrosion demanding individual reports submitted to the relevant authority office. This systematic approach aims to facilitate efficient monitoring and management of corrosion-related issues, ensuring that all identified problems are appropriately documented and rectified. The directive references Fokker document SE-291 Revision 3 for compliance specifics, maintaining the integrity of previously issued directives while introducing this amendment to reflect the most current corrosion prevention and control protocols.

Scope and Application

The Civil Aviation Regulations 1998, as part of the legislative instrument F2006B09692, specifically address the airworthiness directives for Fokker F27 Series aeroplanes, excluding the Mk 050 series. These regulations apply to the maintenance and operation of the affected aircraft models and are enforced by the Civil Aviation Safety Authority (CASA). The directives mandate adherence to the technical requirements outlined in RLD AD 91-113/4(A) concerning corrosion prevention and control. The legislation establishes a tiered reporting system for corrosion findings, where level 1 corrosion need not be reported, level 2 corrosion may be consolidated into a single report detailing corrective actions submitted to the relevant Authority District Office, and level 3 corrosion must be reported individually. The compliance with these directives is to be achieved as specified in the requirement document, with this amendment taking effect from 9 November 1995. The directive reflects updates from the latest revision of the corrosion control program document, as referenced in Fokker document SE-291 Revision 3.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, contain the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which governs the maintenance and safety requirements of aircraft. One such directive, AD/F27/125 Amendment 3, pertains to the Fokker F27 series aeroplanes, excluding the Mk 050 series, and is focused on corrosion prevention and control. This amendment mandates that operators must adhere to the technical requirements of RLD AD 91-113/4(A) (section 1). Corrosion identified at level 1 does not need to be reported, while level 2 corrosion can be consolidated into a single report of corrective action, which must be submitted to the Authority District (Airport) Office within sixty days, using a single MDR (section 2). Any level 3 corrosion must be reported individually via an MDR (section 3). The directive imposes specific obligations on the parties involved, primarily the aircraft operators. These obligations include implementing a corrosion prevention and control program as required by the Country of Origin Airworthiness Authority, which aims to prevent structural degradation of the aircraft (section 4). The directive further specifies the reporting requirements for different levels of corrosion identified during the maintenance or inspection processes, ensuring that all necessary information is accurately communicated to the relevant authorities (section 5). Compliance with these directives is crucial for maintaining the airworthiness of the Fokker F27 series aeroplanes. Failure to comply with the requirements of AD/F27/125 Amendment 3 can result in significant consequences. While the specific offences and penalties are not detailed within this directive, non-compliance with airworthiness directives generally can lead to enforcement actions by the Civil Aviation Safety Authority. These actions may include administrative penalties, enforcement actions, or even the grounding of aircraft if the non-compliance poses a safety risk. The severity of the penalties can vary depending on the nature and extent of the breach, but they can include fines and other sanctions as prescribed by relevant aviation laws (section 6).
