COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Short SD3-30 Series Aeroplanes
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/SD3-30/38 and issues the following 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.
Applicability: All SD3-30 aircraft.
Requirement: Action in accordance with Shorts Mandatory Service Bulletin SD330-53-68 Revision 1.
Compliance: Initial Inspection: Before 25 September 1999.
Subsequent Inspection:
Where no corrosion is found, or where all corroded items have been replaced in accordance with the Requirement document, inspect in accordance with Aircraft Maintenance Program Chapter 5-26-57.
Where corrosion is found and remedial action taken to remove the corrosion, inspect in accordance with the Requirement document every 12 calendar months thereafter.
The compliance time for the initial inspection remains unchanged for this issue of the Directive.
This amendment becomes effective on 9 August 2001.
Background: Corrosion has been found in the area of the lower and upper shear decks and outer and inner ribs, especially the flanges.
Amendment 1 is issued in response to a revision of the Requirement document, which introduces changes to clarify repeat inspection requirements and accomplishment instructions.

SCHEDULE OF AIRWORTHINESS DIRECTIVES
The original issue of this Airworthiness Directive became effective on 25 March 1999.

Delegate of the Civil Aviation Safety Authority 26 June 2001
The above AD is notified in the Commonwealth of Australia Gazette on 11 July 2001.
Overview
The Civil Aviation Regulations 1998, as amended, were enacted by the Australian Parliament to regulate civil aviation safety within the country. The Regulations establish the framework for ensuring the safety of aircraft and aeronautical products, and one specific mechanism for maintaining safety standards is through Airworthiness Directives (ADs). In response to identified safety concerns, the Civil Aviation Safety Authority (CASA) issues ADs to address specific unsafe conditions that may exist in certain aircraft or aeronautical products. These ADs mandate corrective actions to be taken to mitigate identified safety risks, ensuring the continued airworthiness of affected aircraft. The policy objective of the ADs is to enhance the safety of civil aviation by mandating timely and effective corrective actions in response to identified hazards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39, applies to all SD3-30 series aircraft within the Australian jurisdiction, and the Airworthiness Directive (AD) SD3-30/38 concerns the mandatory inspection and maintenance requirements to address corrosion issues identified in certain structural components of these aircraft. This AD is issued under the authority of the Civil Aviation Safety Authority (CASA) and is applicable to all SD3-30 aircraft operating in Australia. The AD mandates that the corrective actions be taken as outlined in the associated Shorts Mandatory Service Bulletin, particularly Revision 1. The requirement includes conducting an initial inspection before 25 September 1999 and subsequent inspections at intervals of up to 12 months, depending on the findings and actions taken during the inspection. This AD, which became effective on 9 August 2001, was issued to address corrosion found in specific areas of the aircraft, namely the lower and upper shear decks and outer and inner ribs, especially the flanges. The AD also clarifies the inspection requirements and instructions for accomplishing the necessary repairs and maintenance.
Key Provisions
The Airworthiness Directive (AD) AD/SD3-30/38 issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) applies to all SD3-30 aircraft (Section 39.105). The directive requires that action be taken in accordance with Shorts Mandatory Service Bulletin SD330-53-68 Revision 1 to address corrosion found in the lower and upper shear decks, outer and inner ribs, particularly the flanges (Section 39.105). The AD specifies that the initial inspection must be conducted before 25 September 1999 (Section 39.105). If no corrosion is found or if all corroded items are replaced according to the requirement document, subsequent inspections should be carried out in line with Aircraft Maintenance Program Chapter 5-26-57. However, if corrosion is found and remedial action is taken, inspections must be conducted in accordance with the requirement document every 12 calendar months thereafter (Section 39.105). The compliance time for the initial inspection remains unchanged, and this amendment becomes effective on 9 August 2001 (Section 39.105).
Under this legislation, the primary obligation for the parties involved is to ensure that inspections and necessary repairs are carried out as specified in the AD (Section 39.105). Operators of SD3-30 aircraft must adhere to the inspection schedule and comply with the mandatory service bulletin to maintain the airworthiness of their aircraft. This involves conducting an initial inspection before the specified deadline and subsequent inspections at the prescribed intervals, depending on the findings of the initial inspection (Section 39.105). Failure to comply with these requirements could result in the aircraft being deemed unairworthy, leading to potential safety risks and legal consequences.
In terms of consequences for non-compliance, the AD does not explicitly outline specific penalties or legal repercussions in the provided text. However, the overarching legal framework under CAR 1998 and the authority of the Civil Aviation Safety Authority (CASA) implies that non-compliance with airworthiness directives can result in serious civil or criminal penalties. These may include fines, suspension or revocation of airworthiness certificates, and potential criminal charges if the non-compliance leads to accidents or unsafe conditions. The exact penalties would depend on the severity of the non-compliance and any resultant harm or safety risks.
