COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety 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 revokes Airworthiness Directive (AD) AD/B737/164 and issues the following AD under subregulation 39.1 (1) of CASR 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 737 Series Aeroplanes
AD/B737/164
Amdt 1
Elevator Tab Repair 13/2003
Applicability: All Model 737-600, -700, -700C, and -800 series aircraft.
Requirement: Installation of repairs on any elevator tab shall be accomplished in accordance with Boeing All Operator Message M-7200-01-00756 Revision 1, dated 29 May 2001
Note 1: FAA AD 2001-14-05 Amdt 39-12315 refers.
Compliance: As of 15 August 2001. Compliance with AD/B737/210 (FAA AD 2003-03-22) constitutes terminating action for the requirements of this Directive.
The compliance time remains unchanged by this issue. This Amendment becomes effective on 25 December 2003.
Background: The FAA is prohibiting repair of the elevator tab using previously approved repair procedures. This action prevents installation of repairs that are outside allowable limits, which can adversely affect the weight and centre of gravity of the elevator tab and result in excessive in-flight vibrations; and consequent loss of controllability of the aircraft.
Amendment 1 is issued to introduce terminating action for the requirements of this Directive.
The original issue of this Airworthiness Directive became effective on 15 August 2001.
David Villiers
Delegate of the Civil Aviation Safety Authority 13 November 2003
The above AD is notified in the Commonwealth of Australia Gazette on 3 December 2003.

Overview
The Civil Aviation Safety Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) and enacted by the Parliament of Australia, were established to ensure the safety of civil aviation in Australia by setting out regulatory requirements for the maintenance and operation of aircraft. This legislative instrument specifically addresses safety concerns regarding the Boeing 737 series aeroplanes by introducing Airworthiness Directive AD/B737/164, Amendment 1, which mandates particular repair procedures for elevator tabs to prevent unsafe conditions that could lead to in-flight control issues. The policy objective behind this directive is to ensure that all repairs to the specified aircraft models are conducted according to precise standards, thus maintaining the integrity and safety of the aircraft in accordance with international safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998 (CASR 1998) under the authority of the Civil Aviation Safety Authority (CASA) provide a comprehensive framework for ensuring the safety of civil aviation within Australia. Specifically, Part 39 of the regulations outlines the process for issuing Airworthiness Directives (ADs) which are mandatory instructions issued to correct an unsafe condition on an aircraft. The applicability of these directives is stringent, applying to specific models of aircraft, such as all Boeing 737-600, -700, -700C, and -800 series aeroplanes, and mandating that elevator tab repairs be performed according to the instructions specified in Boeing All Operator Message M-7200-01-00756 Revision 1. These directives aim to ensure that such repairs adhere to strict safety standards to prevent adverse effects on the aircraft’s weight, centre of gravity, and overall controllability. Compliance with these directives is mandatory, with a compliance date set from 15 August 2001, and any deviation could result in significant safety risks.
Key Provisions
The Civil Aviation Safety Regulations 1998 (CASR), specifically Part 39, Section 105, outlines a series of Airworthiness Directives (ADs) aimed at ensuring the safety of civil aviation in Australia. Section (a) of the AD/B737/164 (13/2003) applies to all Boeing 737-600, -700, -700C, and -800 series aircraft. The directive mandates that any repairs to the elevator tab must adhere to Boeing All Operator Message M-7200-01-00756 Revision 1, dated 29 May 2001, and references FAA AD 2001-14-05 Amdt 39-12315. Compliance with these specific repair procedures is crucial to prevent adverse effects on the elevator tab’s weight and centre of gravity, which could lead to in-flight vibrations and loss of controllability.
The obligations imposed by this AD are clear: operators of the specified Boeing 737 models must follow the detailed repair procedures outlined in the referenced Boeing All Operator Message. This includes ensuring that all personnel involved in the repair process are adequately trained and that the repairs are performed in a manner consistent with the specified standards. Operators must also ensure that any repairs completed before the compliance date of 15 August 2001, as referenced in the AD, meet the standards set forth in the AD/B737/210 (FAA AD 2003-03-22), which serves as terminating action for the requirements of this Directive.
Failure to comply with the provisions of the AD/B737/164 could result in severe consequences. While the specific penalties are not detailed within the text, it is implied that non-compliance with ADs can lead to serious safety issues, potentially resulting in aircraft being grounded until the required repairs are made. Additionally, there may be civil or criminal penalties imposed by the Civil Aviation Safety Authority (CASA) for non-compliance with safety regulations. These penalties can include fines and other sanctions, which are intended to enforce adherence to safety standards and protect the public.
