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.
Extra EA-300 Series Aeroplanes
AD/EXTRA/7 Upper Longeron at Horizontal Stabiliser 2/2003
TX
Applicability: Model EA 300 S aircraft, serial numbers 01 through 29.
Requirement: 1. Inspect in accordance with Part I of Extra Mandatory Service Bulletin (MSB) No.
SB-300-2-95 Issue D, dated 30 January 2001.
2. Modify in accordance with Extra MSB No. SB-300-2-95 Issue D.
Note: LBA AD 2003-001 refers.
Compliance: 1. Before further flight after 23 December 2002, unless already accomplished.
2. Before 28 February 2003, unless already accomplished.
This Airworthiness Directive becomes effective on 23 December 2002.
Background: Cracks have been discovered on Model EA 300 S aircraft in front of the horizontal stabiliser attachment as well as between the attachment fittings in the upper longeron. This Directive introduces an additional pair of tubes to improve the stiffness of the fuselage cross-section underneath the stabiliser attachment.

Overview
The Civil Aviation Regulations 1998 (CAR 1998), enacted by the Australian Parliament, provide the legal framework for regulating civil aviation safety in Australia. One specific legislative instrument under this act is the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) in response to identified safety issues. For instance, AD/EXTRA/7 pertains to the Model EA 300 S aircraft with serial numbers 01 through 29. This directive was introduced to address the problem of cracks found in the upper longeron at the horizontal stabiliser of these aircraft, which could compromise structural integrity. The directive mandates specific inspections and modifications to prevent the propagation of these cracks, ensuring that the aircraft remain airworthy. The CASA delegate, David Alan Villiers, issued this directive on 19 December 2002, which became effective on 23 December 2002, with compliance deadlines set for 28 February 2003. The policy objective here is to enhance the safety and reliability of the affected aircraft by implementing necessary corrective actions.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, which pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, sets out stringent requirements to ensure the safety of civil aviation. This particular Airworthiness Directive (AD) applies to Model EA 300 S aircraft with serial numbers ranging from 01 to 29, highlighting the necessity for inspections and modifications to address identified structural issues. The AD mandates that inspections be conducted in accordance with Extra Mandatory Service Bulletin (MSB) No. SB-300-2-95 Issue D, dated 30 January 2001, and modifications be made in line with the same bulletin. The directive underscores that these actions must be completed before further flights after 23 December 2002, and in any case, before 28 February 2003, unless already undertaken. This AD, issued by a CASA delegate, is effective from 23 December 2002 and was gazetted to ensure compliance with the specified safety measures.
Key Provisions
The Airworthiness Directive (AD) AD/EXTRA/7, issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998), applies to Model EA 300 S aircraft with serial numbers ranging from 01 to 29. The primary requirement of this AD is that the upper longeron at the horizontal stabiliser must be inspected and modified in accordance with the Extra Mandatory Service Bulletin (MSB) No. SB-300-2-95 Issue D, dated 30 January 2001. The inspection and modification must be carried out before further flight after 23 December 2002, and in any case, before 28 February 2003. This directive aims to address cracks found in the upper longeron at the horizontal stabiliser attachment by enhancing the stiffness of the fuselage cross-section underneath the stabiliser attachment through the addition of an extra pair of tubes.
Operators and owners of the affected Model EA 300 S aircraft must ensure compliance with the AD by conducting the specified inspection and modification before the stipulated dates. This includes following the detailed instructions outlined in the Extra MSB No. SB-300-2-95 Issue D, which provides the technical guidelines for these actions. Failure to adhere to the AD can result in the aircraft not being deemed airworthy, thereby preventing it from being flown until the required actions are completed. The AD is intended to ensure the continued safety of the aircraft by addressing the identified structural issues.
Breaches of the AD can lead to significant consequences. If an operator fails to comply with the AD, the aircraft may be grounded, as it would not meet the required airworthiness standards. This can result in operational disruptions and financial losses. Furthermore, non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Depending on the severity and frequency of non-compliance, penalties can include fines, legal action, and potential criminal charges if the non-compliance results in a safety incident. The maximum penalties for such offences can vary, but they are intended to be stringent enough to ensure compliance and maintain the high safety standards required in civil aviation.
