AD/P166/5 - Engine Nacelle - Drainage Modification

Overview

The Civil Aviation Regulations 1998, as amended and administered by the Civil Aviation Safety Authority, were enacted to ensure the safety and efficiency of civil aviation in Australia. One of the legislative instruments under this act is F2006B05331, which pertains to Airworthiness Directives for the Piaggio P166 Series Aeroplanes. This specific directive, AD/P166/5, addresses an issue related to the engine nacelle drainage, aiming to prevent water accumulation that could potentially affect the aircraft's performance and safety. The policy objective behind these regulations is to maintain the highest safety standards in the aviation industry, ensuring that all aircraft meet stringent airworthiness criteria. The regulations were enacted by the Commonwealth of Australia and are overseen by the Civil Aviation Safety Authority, reflecting the commitment to safeguard public safety in the skies.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which applies to the Piaggio P166 Series Aeroplanes. This directive, denoted as AD/P166/5, mandates that all models of the Piaggio P166 aeroplanes must provide adequate drainage facilities for all sections of the lower nacelles. The regulation applies universally to all Piaggio P166 models, ensuring that each aircraft adheres to the specified safety standards. Compliance with this directive is required immediately, emphasising the urgency and importance of the modification to maintain airworthiness. The scope of this legislation is jurisdictional, applying nationally across Australia as part of the Commonwealth's regulatory framework governing civil aviation safety. There are no exclusions, exemptions, or specific thresholds stated within this directive, meaning it applies uniformly to all relevant aircraft within the scope of the Piaggio P166 series. The directive may be further elaborated or implemented through subordinate instruments, ensuring that all necessary details and procedures are clearly defined and adhered to by the relevant operators and aviation authorities.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically in section 105, address the requirements for airworthiness directives, including those for the Piaggio P166 Series Aeroplanes. The directive AD/P166/5 pertains to engine nacelle drainage modification. The directive mandates that all models of the Piaggio P166 series must be equipped with adequate drainage facilities for all sections of the lower nacelles (section 105). This requirement is intended to ensure that any water accumulation in the nacelles is effectively drained, thereby preventing potential engine damage or operational issues that could arise from water ingress. The obligations imposed by this directive are straightforward and imperative for all operators of the Piaggio P166 series. Operators must ensure that the specified modifications are implemented as soon as possible, as indicated by the term "forthwith" (section 105). This means that the necessary drainage facilities must be installed without undue delay. Compliance with this directive is critical, as it directly impacts the safety and airworthiness of the aircraft. Failure to comply with the requirements set forth in the airworthiness directive AD/P166/5 can lead to serious consequences. The Civil Aviation Safety Authority (CASA) may impose penalties on non-compliant operators. While the exact penalties are not specified in the directive, they can range from fines to more severe repercussions such as grounding of the aircraft until compliance is achieved. The potential civil and criminal consequences underscore the importance of adhering to the stipulated airworthiness requirements.
