COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY

SCHEDULE OF AIRWORTHINESS DIRECTIVES

 



Boeing 727 Series Aeroplanes

 

AIRWORTHINESS DIRECTIVE


For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

 

AD/B727/167 Forward Entry Doorway 6/2000

Applicability: All Model 727 series aircraft.

 

Requirement: Inspect in accordance with the technical requirements of FAA AD 2000-05-19 Amdt 39-11629.

 

Note: Boeing Service Bulletin 727-53-0186 Revision 1 refers.

 

Compliance: As specified in the Requirement document with a revised effective date of 15 June 2000.

 

This Airworthiness Directive becomes effective on 15 June 2000.

 

Background: The FAA received reports of fatigue cracking in the fuselage skin and bonded doublers in the corners above the forward entry doorway. The one-time inspection and follow-on actions and modification are intended to prevent cracking of the fuselage skin and bonded doubler, which could result in reduced structural integrity and consequent loss of cabin pressurisation.

Overview

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, address the issue of ensuring the safety of civil aviation through airworthiness directives. Enacted by the Civil Aviation Safety Authority (CASA), this legislation aims to maintain the safety of aircraft by mandating specific actions to correct unsafe conditions. In the case of the Boeing 727 Series Aeroplanes, an Airworthiness Directive was issued to address reported instances of fatigue cracking in the fuselage skin and bonded doublers above the forward entry doorway, which could potentially compromise structural integrity and cabin pressurisation. This directive, effective from 15 June 2000, requires a one-time inspection and follow-up actions as specified, aiming to prevent the progression of such cracks and ensure continued safe operation of the aircraft.

Scope and Application

The Airworthiness Directive AD/B727/167 issued by the Civil Aviation Safety Authority (CASA) applies to all Boeing 727 series aircraft operating within the Commonwealth of Australia. The directive mandates a specific inspection protocol to address identified safety concerns, namely fatigue cracking in the fuselage skin and bonded doublers located above the forward entry doorway. This requirement is to ensure the structural integrity of the aircraft and prevent potential loss of cabin pressurisation. The directive's compliance must be adhered to as specified within the directive, with a revised effective date of 15 June 2000, and it became effective on the same date. The directive was issued under the Civil Aviation Regulations 1998, which grants CASA the authority to issue such directives to mitigate identified safety risks. The directive refers to the technical requirements outlined in the Federal Aviation Administration's AD 2000-05-19 and Boeing Service Bulletin 727-53-0186 Revision 1 for detailed implementation guidelines.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 and the Airworthiness Directives, establish critical requirements for the safety and maintenance of aircraft, such as the Boeing 727 series aeroplanes. The Airworthiness Directive issued under subregulation 39.1 (1) of CAR 1998, mandates specific actions to address safety concerns identified in these aircraft models. For instance, AD/B727/167 requires a thorough inspection of the forward entry doorway area to prevent fatigue cracking in the fuselage skin and bonded doublers, which could compromise the aircraft’s structural integrity and lead to a loss of cabin pressurisation. This inspection must comply with the technical requirements outlined in FAA AD 2000-05-19 Amdt 39-11629, and references Boeing Service Bulletin 727-53-0186 Revision 1. The directive became effective on 15 June 2000, and compliance with the inspection requirements is mandatory for all Model 727 series aircraft. The obligations imposed by this directive on the parties and entities it governs are stringent and clear. Operators and owners of Boeing 727 series aeroplanes must ensure that the specified inspection is conducted in accordance with the detailed technical requirements set out in the FAA’s directive and Boeing’s service bulletin. This involves adhering to the procedures and standards outlined in these documents to effectively identify and mitigate potential safety risks. The directive underscores the importance of timely and accurate inspections to maintain the airworthiness of the aircraft, thereby ensuring passenger safety and compliance with regulatory standards. Failure to comply with the requirements of the Airworthiness Directive can result in significant legal consequences. The Civil Aviation Regulations 1998 provide for both civil and criminal penalties for breaches of airworthiness directives. Civil penalties may include fines, while criminal penalties can result in imprisonment, reflecting the serious nature of non-compliance with safety directives. The specific maximum penalties for breaches are not detailed in the provided text, but they are substantial, emphasising the regulatory body's commitment to enforcing safety standards rigorously. Operators and owners who neglect their obligations under the directive risk not only financial penalties but also the safety of passengers and crew, as well as the overall integrity of the aviation system.
