AD/G159/27 - Landing Gear and Oxygen Systems Gas Cylinders - Inspection and Replacement

Overview

The Civil Aviation (Airworthiness) Regulations 1988, as amended by Civil Aviation Order (CAO) 105, Schedule of Airworthiness Directives, addresses the need for maintaining specific safety standards for the Gulfstream (Grumman) G.159 series aeroplanes, particularly focusing on the landing gear and oxygen systems gas cylinders. Enacted by the Australian Government through the Civil Aviation Safety Authority (CASA), this legislation aims to ensure the ongoing airworthiness and safety of these aircraft models. By aligning with international standards and directives, such as those from the Federal Aviation Administration (FAA), the regulations seek to mitigate risks associated with the specified components, thereby enhancing the overall safety and reliability of the aircraft in operation. This legislative framework underscores the commitment to maintaining high safety standards in the Australian aviation sector.

Scope and Application

The Civil Aviation Orders (CAO) set forth in Part 105 of the legislative instrument F2006B10071 apply to all Gulfstream (Grumman) G.159 series aeroplanes that include gas cylinders specified in the requirement documents, specifically Grumman Customer Bulletin No. 282 or FAA AD 75-22-22 Amdt. 39-2409. This legislation governs the inspection and replacement of the landing gear and oxygen systems gas cylinders, ensuring they meet the stipulated safety standards. The directive mandates compliance within 100 hours of time in service following 31 March 1975, ensuring that these aircraft maintain their airworthiness as per the specified timelines. The reach of these regulations extends across the Commonwealth, ensuring uniformity and safety standards are upheld nationally. No exclusions, exemptions, or specific thresholds are mentioned in the provided text, and the CAO may extend its application through subordinate instruments as necessary to ensure compliance and safety.

Key Provisions

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, include detailed provisions for ensuring the safety and compliance of various aircraft models, including the Gulfstream (Grumman) G.159 series aeroplanes. Section 105.002 (AD/G159/27) pertains to the inspection and replacement of landing gear and oxygen systems gas cylinders. According to this section, all models of the Gulfstream (Grumman) G.159 series equipped with gas cylinders listed in the requirement documents must comply with the directive. The requirement documents include Grumman Customer Bulletin No. 282 or FAA AD 75-22-22 Amdt. 39-2409. This directive applies to aeroplanes that have accumulated 100 hours of time in service after 31 March 1975. The obligations under Section 105.002 require operators of the Gulfstream (Grumman) G.159 series to ensure that the landing gear and oxygen systems gas cylinders are inspected and replaced if necessary. This inspection must be conducted within 100 hours of time in service after 31 March 1975, as specified in the requirement documents. The compliance with these directives ensures that the aircraft's landing gear and oxygen systems are maintained in a safe and reliable condition, reducing the risk of in-flight failures or emergencies. Failure to comply with the provisions outlined in Section 105.002 may result in civil or criminal consequences. Civil Aviation Regulations, specifically Section 91.701, provide for penalties and enforcement actions against operators who fail to comply with airworthiness directives. The maximum penalty for non-compliance may include fines, suspension, or revocation of the aircraft's certificate of airworthiness. Additionally, criminal penalties may apply if non-compliance results in a serious aviation incident or endangers the safety of passengers or crew. These provisions underscore the importance of adhering to the mandated inspections and replacements to maintain the highest standards of aviation safety.
