Overview
The Civil Aviation Orders, enacted by the Commonwealth of Australia through the Civil Aviation Safety Authority, include a comprehensive schedule of airworthiness directives designed to ensure the safety of aviation operations. One such directive, AD/G159/32 Amendment 1, pertains specifically to the Gulfstream (Grumman) G.159 series aeroplanes, addressing the critical safety issue of prohibiting jumpseat occupancy during taxi, takeoff, or landing to prevent injuries. This directive was introduced to fill a gap in ensuring passenger and crew safety by mandating either the installation of a specific placard or the incorporation of certain structural modifications. The policy objective behind this legislation is to mitigate the risk of accidents by enforcing stringent safety measures, reflecting the Civil Aviation Safety Authority's commitment to maintaining high standards of airworthiness and safety within the aviation industry.
Scope and Application
The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, mandates compliance for all Gulf Stream (Grumman) G.159 series aeroplanes. This directive applies to any jumpseat located between fuselage stations 119 and 169 and aims to prevent injury by prohibiting occupancy during critical phases of flight, namely taxi, takeoff, and landing. Compliance is required within 10 hours of time in service after 15 May 1978, unless the requirement has already been fulfilled. The directive stipulates that either a placard must be installed on the bulkhead adjacent to the jumpseat or an approved alternative location using lettering of at least 3/16 inch (5mm) high, or the aeroplane must be modified according to the specifications provided in the directive. Notably, the directive explicitly states that no concessions for extensions beyond 8 November 1979 will be granted, unless a firm commitment for the availability of the modification kit is provided by 21 July 1978.
Key Provisions
The Civil Aviation Orders under Part 105, specifically AD/G159/32 Amendment 1, mandate the installation of a placard on the GulfStream (Grumman) G.159 series aeroplanes to prevent injuries during critical flight phases. According to Section 1, the placard must either be affixed to the bulkhead adjacent to the jumpseat or any equivalent location approved by the Secretary. The wording on the placard must be at least 3/16 inch (5mm) high and state “JUMPSEAT OCCUPANCY DURING TAXI, TAKEOFF OR LANDING PROHIBITED.” Alternatively, Section 2 allows for a modification to the nose landing gear drag strut (fused) or the bulkhead in accordance with GAAC Service Change No. 226, Part 1 or Part 11 as applicable. The placard can be removed if either of these modifications is incorporated or if an extension of compliance is granted by concession. Compliance with these requirements must be achieved within 10 hours of time in service following 15 May 1978, unless the requirement has already been met.
Operators and entities governed by this legislation must ensure that the specified placard is installed or the required modifications are completed within the stipulated timeframe. They must also keep records of compliance and be prepared to demonstrate adherence to the Civil Aviation Safety Authority’s directives. Additionally, any requests for concessions must be made well in advance, with evidence of commitment to the availability of the modification kit provided by 21 July 1978. Failure to comply with these provisions may result in safety risks and potential legal consequences.
Breach of the requirements outlined in AD/G159/32 Amendment 1 may result in significant consequences. Under Section 3, there are no specific penalties mentioned in the text, but non-compliance with Civil Aviation Orders generally can lead to enforcement actions, fines, and potentially criminal charges for serious breaches. The maximum penalties for such breaches can include substantial fines and imprisonment, depending on the severity and impact of the non-compliance. Operators must therefore take these requirements seriously to avoid any legal ramifications and to maintain the safety standards required by the Civil Aviation Safety Authority.
