COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 727 Series Aeroplanes
AD/B727/137
Amdt 1
Brake Wear Limit 11/92
Applicability: Model 727 series, equipped with brake part numbers identified in Tables 1 and 2 of the Requirement Document, and BF Goodrich brake P/N 2-873.
Requirement: Action IAW the technical requirements of FAA AD 92-12-08 Amdt 39-8269. Compliance: As specified in the Requirement Document with a revised effective date of 15
October 1992 for Australian registered aircraft.
Background: An investigation by the FAA of a runway excursion by a transport category aircraft following a rejected takeoff, has revealed that the majority of brake assemblies were near the current maximum wear limit and unable to absorb the required energy. This Directive required new maximum brake wear limits. Amendment 1 is issued to reflect the requirements of FAA AD 92-12-08 which lists certain additional landing gear brakes.
Overview
The Civil Aviation Regulations 1998, which are administered by the Civil Aviation Safety Authority, include Part 39 - 105 and the Schedule of Airworthiness Directives. This legislation was enacted to ensure the safety of civil aviation in Australia by addressing various aircraft maintenance and operational issues. One such issue is addressed by the Airworthiness Directive AD/B727/137 Amendment 1, which pertains specifically to the Boeing 727 series aeroplanes. The directive was introduced to tackle the problem of brake wear limits following an investigation by the Federal Aviation Administration (FAA) into a runway excursion incident. The policy objective is to enhance safety by enforcing stricter brake wear limits as specified in FAA AD 92-12-08 Amendment 39-8269, thereby ensuring that Australian registered aircraft meet these enhanced safety standards.
The Airworthiness Directive AD/B727/137 Amendment 1 mandates that Boeing 727 series aeroplanes equipped with specific brake parts must adhere to new maximum brake wear limits to prevent runway excursions and other safety incidents. This requirement was established after an investigation revealed that many brake assemblies were nearing their maximum wear limit and were unable to absorb the required energy during a rejected takeoff, leading to the runway excursion. Compliance with this directive involves adhering to the technical requirements outlined in FAA AD 92-12-08 Amendment 39-8269, with a revised effective date of 15 October 1992 for Australian registered aircraft. The directive aims to ensure that all relevant aircraft maintain adequate brake performance to enhance overall aviation safety.
Scope and Application
The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically AD/B727/137 Amendment 1, pertains to Boeing 727 series aeroplanes equipped with certain brake parts and the BF Goodrich brake P/N 2-873. This directive applies to all aircraft registered in Australia that meet the specified model and brake part numbers, ensuring they adhere to the technical requirements outlined in FAA AD 92-12-08 Amendment 39-8269. Compliance with these directives is mandatory for the safety of Australian registered aircraft, with a revised effective date of 15 October 1992. The directive was prompted by a Federal Aviation Administration (FAA) investigation into a runway excursion incident where the majority of brake assemblies were found to be near the maximum allowable wear limit, highlighting the need for stricter brake wear limits to prevent future incidents.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, include a schedule of airworthiness directives that govern the maintenance and operational standards for various aircraft models. One such directive, AD/B727/137 Amendment 1, pertains to the Boeing 727 series aeroplanes and addresses brake wear limits (sections as referenced in the legislative instrument). This directive applies to Boeing 727 models equipped with specific brake parts identified in the Requirement Document, including BF Goodrich brake part number 2-873. The primary requirement of this directive is for aircraft to comply with the technical standards outlined in FAA AD 92-12-08 Amendment 39-8269, which includes implementing new maximum brake wear limits.
In terms of obligations, the directive requires that the specified Boeing 727 series aircraft must adhere to the newly set brake wear limits to ensure safety and compliance with Australian aviation standards. This involves detailed inspections and maintenance actions as specified in the Requirement Document, which has been revised to reflect an effective date of 15 October 1992 for Australian registered aircraft. This means that operators of the affected Boeing 727 series must conduct thorough checks on their brake assemblies, ensuring they fall within the newly established limits to prevent any potential safety issues.
The directive also imposes specific requirements on compliance. Operators must follow the guidelines provided in the Requirement Document to ensure that their aircraft meet the new standards. This includes the need for thorough documentation and record-keeping of inspections and any maintenance actions taken to comply with the directive. Failure to comply with these requirements could result in serious safety implications, including the potential for increased risk of runway excursions or other accidents related to brake failure.
Should an operator fail to comply with the provisions of this airworthiness directive, they may face significant consequences. The Civil Aviation Regulations 1998 outline potential penalties for non-compliance, which can include both civil and criminal penalties. The exact penalties depend on the severity of the breach, but in some cases, they can result in substantial fines or even imprisonment for serious violations. The directive emphasises the importance of adhering to these standards to maintain the safety of air travel.
