Background: The UK CAA requires a periodic inspection of the engine pod mounting feet, and replacement of any mounting foot found to contain a crack.
Overview
The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses safety concerns regarding the maintenance and inspection of aircraft, particularly focusing on ensuring the airworthiness of specific aircraft models. Enacted by the Parliament of the Commonwealth of Australia, this regulation aims to mitigate risks associated with aviation safety by mandating specific inspections and maintenance actions. The enactment of these regulations aims to ensure the ongoing safety and reliability of civil aviation operations within Australia, aligning with the overarching policy objective of maintaining high safety standards in the national airspace.
The legislative instrument F2006B11414, issued under the authority of the Civil Aviation Regulations 1998, targets the OA7 Optica aircraft by mandating compliance with FLS Aerospace Service Bulletin OA7/SB/0040, which includes detailed requirements for the inspection and replacement of engine pod mounting feet. This directive is crucial for addressing a specific safety concern identified in the UK Civil Aviation Authority's AD 010-03-94, which requires periodic inspections and necessary repairs to prevent structural failure in the engine pod mounting feet. The regulation ensures that these inspections are conducted at regular intervals, specifically every 50 flight hours following the directive's issuance date of 23 June 1994, thereby reinforcing the commitment to aviation safety and operational reliability.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the OA7 Optica series aeroplanes manufactured by FLS Aerospace. The regulations mandate that certain maintenance actions must be undertaken in compliance with FLS Aerospace Service Bulletin OA7/SB/0040, which was issued in response to UK Civil Aviation Authority Airworthiness Directive 010-03-94. The scope of this legislation encompasses all OA7 Optica aircraft operating within Australia, ensuring that these aircraft meet the specified safety standards. The requirement necessitates periodic inspections of the engine pod mounting feet, with a particular focus on identifying and replacing any mounting feet that exhibit cracks. These inspections must occur at the next 50-hour inspection following 23 June 1994, and subsequently at every 50-hour interval thereafter. This regulation is instrumental in maintaining the airworthiness of the OA7 Optica aircraft and ensuring adherence to international safety standards.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive (AD) for FLS Aerospace OA7 Optica Series Aeroplanes, identified as AD/OPTICA/2, concerning the Engine Pod Mounting Feet (Section 7/94). This directive applies to model OA7 Optica aircraft and requires compliance with FLS Aerospace Service Bulletin OA7/SB/0040. The directive notes a reference to UK Civil Aviation Authority AD 010-03-94, indicating alignment with international safety standards.
Under the AD, the aircraft must undergo an inspection of the engine pod mounting feet at the next 50-hour inspection following 23 June 1994, and subsequently at every 50-hour inspection thereafter (Section 7/94). The primary requirement is to ensure that any mounting foot exhibiting a crack is replaced. This aligns with the periodic inspection protocol established by the UK CAA, reinforcing a safety standard across jurisdictions.
Entities governed by this directive, such as aircraft operators and maintenance providers, are obligated to conduct these inspections and necessary replacements to maintain the airworthiness of the aircraft (Section 7/94). This includes documenting each inspection and any actions taken, ensuring traceability and compliance with regulatory requirements.
Failure to comply with these directives can result in serious consequences, potentially leading to aircraft being deemed unairworthy. Such non-compliance could also expose parties to civil or criminal liability, including potential fines or other penalties as stipulated by relevant aviation laws. The specific penalties are not detailed in this AD but may be found within broader regulatory frameworks.
