COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
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.
Boeing 747 Series Aeroplanes
AD/B747/287 Drip Shield and Supports above Rudder Pedal
Mechanism
3/2003
Applicability: Model 747-400 and -400D series aircraft, as listed in Boeing Service Bulletin 747-25A3271 Revision 1 dated 19 December 2001.
Requirement: Action in accordance with the technical requirements of FAA AD 2003-02-02 Amdt 39-13018.
Compliance: As specified in the Requirement document for the initial and repetitive inspections, with a revised effective date of 20 March 2003.
This Airworthiness Directive becomes effective on 20 March 2003.
Background: This Directive requires inspections to detect discrepancies of the drip shield and supports located above the rudder pedals. The inspections and eventual terminating action specified by this Directive are intended to prevent unrestrained drip shields from interfering with the rudder pedal mechanism, which could result in reduced controllability of the aircraft.

Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, provide a comprehensive regulatory framework for ensuring the safety and airworthiness of aircraft within Australian airspace. Part 39 of these regulations, in particular, outlines specific directives that must be followed to maintain the safety standards of aircraft. One such directive, AD/B747/287, was issued to address a specific safety concern identified in Boeing 747-400 and -400D series aircraft. This Airworthiness Directive mandates inspections and corrective actions for the drip shield and supports located above the rudder pedals to prevent potential interference with the rudder pedal mechanism, which could compromise the aircraft's controllability. The directive aims to rectify the identified unsafe condition and ensure the continued airworthiness of these aircraft, aligning with the overarching policy objective of maintaining the highest safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, mandate the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aviation operations within the Commonwealth of Australia. These ADs are specifically applicable to particular aircraft or aeronautical products, such as the Boeing 747 Series Aeroplanes, as illustrated in AD/B747/287. This directive applies to Model 747-400 and -400D series aircraft listed in Boeing Service Bulletin 747-25A3271 Revision 1. The AD requires that certain actions be taken, as specified in the requirement section, which are aligned with the technical requirements of FAA AD 2003-02-02 Amdt 39-13018, to address discrepancies in the drip shield and supports above the rudder pedals. Compliance with this AD involves adhering to the specified inspection schedules and dates outlined in the requirement document, with a revised effective date of 20 March 2003. The directive aims to prevent potential safety hazards, such as the unrestrained drip shield interfering with the rudder pedal mechanism, which could compromise the controllability of the aircraft. This AD was issued by David Alan Villiers, a delegate of the Civil Aviation Safety Authority, and was notified in the Commonwealth of Australia Gazette on 26 February 2003.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, which governs the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, contains specific mandates for maintaining the airworthiness of aircraft. Section 39.1 (1) of these regulations empowers the CASA delegate to issue Airworthiness Directives (ADs) when it is necessary to address identified safety concerns. One such directive, AD/B747/287, pertains to the Boeing 747 Series Aeroplanes and focuses on the drip shield and supports above the rudder pedal mechanism (section 3). This AD became effective on 20 March 2003, following its publication in the Commonwealth of Australia Gazette on 26 February 2003.
Under this AD, the specified applicability (section 3(a)) includes Model 747-400 and -400D series aircraft, as referenced in Boeing Service Bulletin 747-25A3271 Revision 1 dated 19 December 2001. The requirement (section 3(b)) mandates action in accordance with the technical specifications outlined in the Federal Aviation Administration (FAA) AD 2003-02-02 Amdt 39-13018. Compliance (section 3(c)) is governed by the timing and method detailed in the requirement document, specifically for initial and repetitive inspections with a revised effective date of 20 March 2003. The directive aims to ensure that any discrepancies in the drip shield and its supports, which could potentially interfere with the rudder pedal mechanism, are identified and rectified to prevent reduced controllability of the aircraft.
The obligations imposed by this AD on the relevant parties include conducting thorough inspections as per the FAA AD 2003-02-02 Amdt 39-13018 to detect and correct any issues with the drip shield and supports above the rudder pedals. This involves following the specific instructions and timelines set out in the directive to maintain the airworthiness of the affected aircraft models. Failure to comply with the AD could result in significant safety risks, as unrestrained drip shields could interfere with the rudder pedal mechanism, potentially compromising the controllability of the aircraft during flight.
Should any party or entity fail to adhere to the AD, there could be serious civil and criminal consequences. The regulations do not explicitly detail the specific penalties for non-compliance in this context, but generally, non-compliance with ADs can result in enforcement actions by CASA, which may include fines, suspension or revocation of aircraft certificates of airworthiness, and potential criminal charges for serious violations. The severity of penalties may depend on the nature and impact of the non-compliance on aviation safety.
