AD/F50/41 - Outboard Flap Drive

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, address the safety directives pertaining to airworthiness, with a particular focus on ensuring that aircraft maintain the required safety standards. Enacted by the Commonwealth of Australia, these regulations are administered by the Civil Aviation Safety Authority (CASA). The legislation aims to fill the gap in maintaining the airworthiness of aircraft, ensuring that any identified issues, such as those related to the outboard flap drive of the Fokker F50 (F27 Mk 50) series aeroplanes, are rectified to maintain safety standards. The policy objective is to mandate compliance with the applicable safety directives and requirements, thereby preventing potential hazards associated with non-compliant aircraft components. The specific legislative instrument F2006B09868, under the Civil Aviation Regulations 1998, targets the Fokker F50 (F27 Mk 50) series aeroplanes, identifying serial numbers 20103 and 20107 as requiring action in accordance with the Requirement Document RLD AD 90-148. The problem addressed by this directive is the non-compliance of certain outboard flap drive assemblies with current regulations. Compliance with the directive is essential to ensure that these aircraft meet the necessary safety standards, as outlined in the referenced Fokker SB F50-27-026.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety standards and requirements for civil aviation in Australia. The legislation mandates that certain Fokker F50 (F27 Mk 50) series aeroplanes, namely those with serial numbers 20103 and 20107, comply with Airworthiness Directive AD/F50/41 concerning the outboard flap drive. This requirement is directly tied to the need for adherence to the RLD AD 90-148, with reference to Fokker Service Bulletin F50-27-026. Compliance with these directives is essential to ensure the continued airworthiness of the specified Fokker F50 aircraft, which necessitates corrective actions as outlined in the relevant Requirement Document. The scope of this legislation extends to ensuring that the mentioned aircraft models meet the necessary safety standards, thereby safeguarding the integrity and safety of civil aviation operations within the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, which addresses the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, contains AD/F50/41 concerning the Fokker F50 (F27 Mk 50) Series Aeroplanes. This directive applies to the model F27 MK 50 with serial numbers 20103 and 20107 (section 1). It mandates that these aircraft must comply with the action stipulated in RLD AD 90-148, referencing Fokker SB F50-27-026 (section 2). Compliance must align with the specified requirements outlined in the Requirement Document (section 3). Under these regulations, the primary obligation for the operators and owners of the affected Fokker F50 aircraft is to ensure that the outboard flap drive assemblies are brought into compliance with the stated directives. This involves following the specific instructions and procedures laid out in RLD AD 90-148 and the Fokker Service Bulletin F50-27-026. Operators must verify that the modifications or checks are performed by qualified personnel and documented accordingly. Failure to adhere to these compliance requirements can result in serious safety risks, including potential operational restrictions or grounding of the aircraft. Breaching the provisions of AD/F50/41 may result in various consequences. The Civil Aviation Safety Authority has the authority to impose penalties on operators who fail to comply with airworthiness directives. Such penalties can include fines, enforcement actions, and the potential grounding of the non-compliant aircraft until the necessary actions are taken. The severity of the penalties can vary depending on the extent of non-compliance and any subsequent risk posed to aviation safety. While the specific maximum penalties are not detailed in the extract, they are typically substantial, reflecting the critical nature of airworthiness compliance.
