AD/F27/96 - Pitot Static System - Modification

Overview

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, enacted as part of the Civil Aviation Regulations 1998, addresses specific safety concerns related to aircraft operations. One such directive, AD/F27/96, was introduced to address the identified problem of potential failures in the pitot static system of Fokker F27 series aeroplanes. This legislation was enacted to ensure the airworthiness of these aircraft by mandating modifications to the pitot static system. The directive applies to all model F27 aeroplanes with serial numbers ranging from 10505 to 10547 and 10550. Compliance with this directive is required within 800 hours of time in service after 30 September 1978, as specified in Fokker F27 Service Bulletin No. 34-41 or BLA 78-40-34. The policy objective of this directive is to enhance flight safety by mitigating risks associated with the pitot static system.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/F27/96, applies to all Fokker F27 series aeroplanes with serial numbers (S/Nos) ranging from 10505 to 10547 and 10550. This legislation pertains to the modification of the pitot static system in these specific aircraft models to ensure continued airworthiness and compliance with the Civil Aviation Regulations 1998. The directive mandates compliance within 800 hours of time in service following the directive's issuance on 30 September 1978. The modifications must align with either Fokker F27 Service Bulletin No. 34-41 or the British Light Aircraft 78-40-34 directive. The directive is applicable to aircraft operators and maintenance personnel who must ensure the specified modifications are implemented within the stipulated timeframe. The scope of the legislation is focused on enhancing safety and regulatory compliance for the designated Fokker F27 series aeroplanes within the Australian jurisdiction.

Key Provisions

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically pertaining to Fokker F27 Series Aeroplanes, mandates particular modifications to the pitot static system (Section 105). This directive, known as AD/F27/96, applies to all Fokker F27 aeroplanes with serial numbers (S/Nos) ranging from 10505 to 10547 and 10550. Compliance with this directive is crucial and must be achieved within 800 hours of time in service after 30 September 1978. This timeframe is non-negotiable and must be strictly adhered to by all operators of the specified Fokker F27 models. The modifications are outlined in two documents: Fokker F27 SB No. 34-41 or BLA 78-40-34, both of which provide detailed instructions on how the required changes should be implemented. Operators of the affected Fokker F27 aeroplanes are obligated to ensure that the modifications to the pitot static system are carried out in accordance with the specified documents. This includes the installation of any required components, the execution of necessary adjustments, and the performance of any testing that confirms the system's compliance with the safety standards set by the Civil Aviation Safety Authority. It is imperative that these modifications be performed by certified personnel to ensure that the safety requirements are fully met. The directive does not merely suggest improvements but mandates specific actions that must be taken to maintain the airworthiness of the aircraft. Failure to comply with the provisions of this airworthiness directive can lead to serious legal consequences. The Civil Aviation Regulations 1998, which govern these directives, include provisions for both civil and criminal penalties for non-compliance. Civil penalties may include fines and the possibility of grounding the aircraft until compliance is achieved. Criminal penalties can also be imposed, which may include imprisonment for individuals who knowingly and wilfully fail to adhere to the mandated modifications. The specific penalties can vary based on the severity of the breach and the intent behind it, but the overarching principle is that non-compliance will not be tolerated and will be met with appropriate legal action. The maximum penalties for violations of the Civil Aviation Regulations 1998 can be substantial. For corporate entities, fines can be quite significant, often running into hundreds of thousands of dollars. For individual officers or directors of the companies, the penalties can include imprisonment, with the length of the sentence depending on the severity and intentionality of the breach. It is essential for all parties involved in the operation of Fokker F27 aeroplanes to understand and comply with the requirements of AD/F27/96 to avoid these serious consequences. The directive is clear and unambiguous in its demands, leaving no room for interpretation regarding the necessity of compliance.
