SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/EXTRA/5 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.
Extra EA-300 Series Aeroplanes
AD/EXTRA/5
Amdt 1
Upper Longeron Cutout Bridge 9/2004
Applicability: Model EA-300 aircraft, serial numbers V1 and 01 through 50, and Model EA-300/S aircraft, serial numbers 01 through 17.
Requirement: Action in accordance with the requirements of Extra Service Bulletin SB-300-3-93 Issue B, dated 10 June 1998.
Note 1: If aircraft is modified in accordance with Procedure I of SB-300-3-93 Issue B, no further action is required.
Note 2: LBA AD D-1994-043R1 refers.
Compliance: Before the accumulation of 1,000 flight hours.
If action is required in accordance with Procedure II, exchange the bridges at intervals not to exceed 1,000 flight hours.
This Amendment becomes effective on 2 September 2004.
Background: Cracking has been experienced during the fatigue test.
Amendment 1 is issued in response to a new LBA AD, which was prompted by in- service reports of cracking of the upper longeron cutout-bridge.
The original issue of this Airworthiness Directive became effective on 9 November 1995.

Overview
The Civil Aviation Safety Regulations 1998, particularly as amended by the Civil Aviation Safety Regulations 1998 Amendment (Airworthiness Directives) (No. 1) 2004, address a specific safety concern related to the upper longeron cutout bridge in Extra EA-300 Series aeroplanes. The regulations were enacted by the Parliament of Australia and administered by the Civil Aviation Safety Authority (CASA) to ensure that civil aviation operations in Australia meet safety standards. This particular amendment was introduced to address a safety issue identified in the Extra EA-300 Series aircraft, where cracking was experienced during fatigue tests of the upper longeron cutout bridge. The policy objective is to mitigate potential risks associated with this structural component by mandating specific maintenance actions or modifications, ensuring that the aircraft remain airworthy and safe for operation.
The Civil Aviation Safety Regulations 1998 Amendment (Airworthiness Directives) (No. 1) 2004, issued by CASA, revokes the previous Airworthiness Directive AD/EXTRA/5 and introduces a new directive requiring specific actions in response to identified safety concerns. This legislative instrument aims to ensure that aircraft remain compliant with airworthiness standards by specifying that any affected aircraft must be modified or maintained in accordance with the Extra Service Bulletin SB-300-3-93 Issue B, dated 10 June 1998. This directive is designed to prevent in-service cracking and maintain the structural integrity of the aircraft, thus ensuring ongoing safety in civil aviation.
Scope and Application
This Airworthiness Directive, issued under the Civil Aviation Safety Regulations 1998, pertains specifically to certain models of the Extra EA-300 series aeroplanes. The directive applies to the Extra EA-300 aircraft with serial numbers V1 and 01 through 50, as well as the Extra EA-300/S aircraft with serial numbers 01 through 17. The directive requires corrective action to address a safety concern identified in the upper longeron cutout bridge of these aircraft. The action required is in accordance with the procedures outlined in Extra Service Bulletin SB-300-3-93 Issue B, dated 10 June 1998. Notably, if the aircraft has been modified in accordance with Procedure I of the bulletin, no further action is necessary. However, if Procedure II applies, the bridges must be exchanged at intervals not exceeding 1,000 flight hours. The directive must be complied with before the aircraft accumulates 1,000 flight hours. The directive revokes the previous AD/EXTRA/5 and becomes effective from 2 September 2004, responding to reports of in-service cracking of the upper longeron cutout-bridge, and references the LBA AD D-1994-043R1.
Key Provisions
The main operative sections of this legislative instrument include the applicability, requirement, and compliance sections of the Airworthiness Directive (AD) AD/EXTRA/5. The AD applies to specific models of Extra EA-300 aircraft with certain serial numbers and mandates actions to address a known safety issue related to the upper longeron cutout bridge. The requirement section specifies that action must be taken in accordance with the Extra Service Bulletin SB-300-3-93 Issue B, dated 10 June 1998, with particular attention to Procedure I or Procedure II, depending on the condition of the aircraft. The compliance section outlines the timeline for taking the required action, which must occur before the aircraft accumulates 1,000 flight hours, or at intervals not exceeding 1,000 flight hours if action is required under Procedure II.
The obligations imposed by this AD are primarily on aircraft operators and maintenance personnel. They must ensure that the specified aircraft undergo the necessary inspection and maintenance actions as outlined in the Extra Service Bulletin SB-300-3-93 Issue B. This includes determining whether the aircraft requires modification under Procedure I or if it needs bridge replacement under Procedure II. Operators and maintenance personnel are required to follow the instructions meticulously to maintain the airworthiness of the aircraft and prevent potential safety hazards associated with the cracking of the upper longeron cutout bridge.
Failure to comply with the AD and its requirements can lead to serious safety issues, and the regulations do not explicitly outline penalties. However, non-compliance with airworthiness directives can result in the aircraft being deemed unairworthy, which could lead to grounding and potential enforcement actions by the Civil Aviation Safety Authority (CASA). In severe cases, it may also result in civil or criminal liability for the aircraft operator or maintenance personnel if the non-compliance leads to an accident or incident. The exact penalties would depend on the specific circumstances and any additional regulations that may apply.
