Overview
The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B02660, specifically address the safety concerns related to the Boeing 727 Series aeroplanes. Enacted by the Australian Government, this regulation is part of the broader regulatory framework aimed at ensuring the safety of civil aviation. The policy objective behind this particular amendment is to mandate compliance with the technical requirements outlined by the Federal Aviation Administration (FAA) regarding the main cargo door of Boeing 727 Series aeroplanes. This was introduced to address issues such as worn latch cams, worn pressure relief door hinge fittings, and the critical incident where a main cargo door opened in flight. By aligning with FAA AD 91-22-04 Amdt 39-8064, this regulation seeks to mitigate safety risks and ensure that Australian-registered aircraft meet international safety standards.
Scope and Application
The Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority, specifically address the airworthiness directives for Boeing 727 Series aeroplanes, focusing on the safety of the main cargo door in Part 39 - 105. This regulation applies to all Boeing 727 series aeroplanes that are registered in Australia and mandates adherence to the technical requirements outlined in FAA AD 91-22-04 Amendment 39-8064, with Boeing Service Bulletin 727-52-0142 providing additional guidance. The directive is necessitated by documented instances of worn latch cams, worn pressure relief door hinge fittings, and an incident where a main cargo door opened in flight, thereby necessitating specific actions to ensure the safety of these aircraft. The compliance requirements are detailed in the accompanying documentation, with the revised effective date for Australian registered aircraft set as 12 January 1992, extending the original FAA-mandated date by approximately one month. This regulation ensures that the safety and operational standards of the Boeing 727 series aeroplanes within Australia meet the stringent safety protocols established by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, particularly under Part 39, include specific directives regarding the airworthiness of aircraft, with AD/B727/138 focusing on the Boeing 727 series aeroplanes and their main cargo doors (Section 39-105). This directive requires compliance with the technical specifications outlined in FAA AD 91-22-04 Amendment 39-8064. Boeing Service Bulletin 727-52-0142 is also referenced to provide further guidance on the required actions. The directive applies to the Boeing 727 series as detailed in the requirement document, with a compliance date set for 12 January 1992 for Australian registered aircraft.
This legislation imposes several obligations on the entities and individuals responsible for maintaining the airworthiness of Boeing 727 series aircraft. Operators and maintenance providers must ensure that the main cargo door latch cams and pressure relief door hinge fittings are inspected and, if necessary, repaired or replaced in accordance with the specified technical requirements. These requirements aim to prevent the recurrence of issues such as doors opening in flight due to worn components. Operators must also keep detailed records of all inspections and maintenance actions performed on the cargo doors to demonstrate compliance with the AD.
Failure to comply with the provisions of AD/B727/138 can result in severe consequences, both civil and criminal. Civil penalties for non-compliance can include fines and potential grounding of the aircraft until the required actions are taken. Additionally, individuals or companies found in breach of these regulations may face criminal charges. The maximum penalties can vary, but they are typically substantial, reflecting the critical importance of airworthiness standards to aviation safety. It is imperative for all parties involved in the operation and maintenance of Boeing 727 series aircraft to adhere strictly to these directives to avoid legal repercussions.
