Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address the need for stringent safety measures in civil aviation, particularly concerning aircraft airworthiness and operational safety. This legislative instrument, specifically Amendment 1, pertains to the Gulfstream (Grumman) G1159 and G-IV Series Aeroplanes, focusing on the installation of placards on jumpseats to prevent injuries during critical phases of flight such as taxiing, takeoff, and landing. The amendment mandates that a placard with specific wording must be installed on the bulkhead adjacent to the jumpseat or another location approved by the Secretary, ensuring that the lettering is of a minimum height of 5mm. Alternatively, the installation of a nose landing gear wheel-well bulkhead modification to eliminate drag strut penetration can be an acceptable compliance measure. The requirement to adhere to these directives aims to enhance passenger and crew safety, ensuring that all concerned are aware of the dangers associated with occupying jumpseats during these critical flight phases. Compliance with these directives is mandatory within 10 hours of the aircraft being in service after 15 May 1978, with no concessions extending beyond 8 November 1979.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, applies to all Gulfstream (Grumman) G1159 and G-IV series aeroplanes to ensure their airworthiness. This legislative instrument mandates the installation of a placard on jumpseats located between fuselage stations 119 and 169 to prohibit occupancy during taxi, takeoff, or landing, or the incorporation of a nose landing gear wheel-well bulkhead modification to eliminate drag strut penetration. The requirement applies to all models of the specified aircraft, necessitating compliance within 10 hours of time in service following the directive's issuance on 15 May 1978, with no concessions extending beyond 8 November 1979. The placard can be removed upon implementing the modification or if a compliance extension is granted, provided certain conditions are met. This regulation extends to the entire Commonwealth of Australia, overseen by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain a directive under Schedule of Airworthiness Directives for Gulfstream (Grumman) G1159 and G-IV series aeroplanes. This directive, identified as AD/G1159/21 Amendment 1, pertains to the installation of a placard on jumpseats located between fuselage stations 119 and 169. The primary objective of this directive is to prevent injury to occupants by clearly prohibiting jumpseat occupancy during critical phases of flight such as taxiing, takeoff, and landing. To achieve this, operators must either install a placard on the bulkhead adjacent to the jumpseat or an equivalent approved location, with lettering no less than 3/16 in. (5mm) high, stating "JUMPSEAT OCCUPANCY DURING TAXI, TAKEOFF OR LANDING PROHIBITED", or alternatively, they may implement a modification to the nose landing gear wheel-well bulkhead as per GAAC Service Change No. 226 Part 11 to eliminate drag strut penetration. The placard may be removed upon completion of the specified modification or if a compliance extension is granted. Operators governed by this directive must ensure compliance within 10 hours of time in service following the directive's issuance date of 15 May 1978, unless the requirement has already been fulfilled. It is crucial to note that no extension beyond 8 November 1979 will be granted, and any request for an earlier compliance date must be accompanied by evidence of a firm commitment by the Gulfstream Aerospace Corporation (GAAC) on the availability date for the modification kit for that specific serial number aircraft, submitted to the Secretary by 21 July 1978. This requirement underscores the necessity for timely and effective implementation of safety measures to protect passengers and crew during critical flight operations. Failure to comply with the provisions of this airworthiness directive can result in serious safety implications, potentially leading to injury or worse during flight operations. The directive explicitly prohibits any concession extending compliance beyond the specified deadline, reflecting the importance placed on adhering to these safety protocols. Non-compliance not only poses a risk to the safety of occupants but also may incur legal repercussions. Civil Aviation Regulations, overseen by the Civil Aviation Safety Authority (CASA), mandate stringent adherence to such directives to maintain the highest safety standards in aviation. In the event of non-compliance with the AD/G1159/21 Amendment 1, operators may face civil or criminal penalties as stipulated under the Civil Aviation Act 1988 and associated regulations. The severity of the penalty can vary depending on the nature and extent of the breach, but it may include fines, enforcement actions, and potential grounding of the aircraft until compliance is achieved. Given the critical nature of the safety measures outlined in this directive, CASA may take swift and decisive action against operators who fail to meet these requirements, ensuring that the aviation industry maintains the highest standards of safety and operational integrity.
