COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Compliance: As detailed in the Requirement table.
This Amendment becomes effective on 13 July 2000.
Background: The initial issue of this directive was raised to promulgate the wing and carry-thru structure fatigue life limitations, which were based on the results of a comprehensive program of full scale fatigue tests conducted by the manufacturer. Subsequent amendments updated the lives as the test program continued; and consolidated the content with that of other directives. There are some differences between some of the lives shown above and the corresponding lives shown in SB 744 and the FAA AD, however all Australian lives derive directly from the fatigue test program.
This amendment is issued to clarify that for spar assemblies P/N 97701, only the upper and lower spar caps need be retired.
Amendment 2 of this Airworthiness Directive became effective on 1 September 1982. The original issue of this Airworthiness Directive became effective on
29 November 1974.
Bernard Malcolm Hole
Delegate of the Civil Aviation Safety Authority 31 May 2000
The above AD is notified in the Commonwealth of Australia Gazette on 14 June 2000.
AL 7/2000
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide the legal framework governing civil aviation safety in the country. To address specific safety concerns, the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) under subregulation 39.1 (1) of the Civil Aviation Regulations. One such AD, AD/PA-36/6 Amdt 3, pertains to Piper PA-36 (Pawnee Brave) Series Aeroplanes and was introduced to manage the structural fatigue of wing components. This directive mandates the retirement of certain wing parts at specified service hours to ensure continued airworthiness and safety. The policy objective is to mitigate the risk of structural failure by enforcing timely replacement of critical components based on rigorous fatigue testing data. The AD is issued by a CASA delegate and becomes effective as per the compliance section outlined in the directive.
Scope and Application
The Airworthiness Directive (AD) outlined in the Civil Aviation Regulations 1998 applies to all models of Piper PA-36 (Pawnee Brave) series aeroplanes, specifically targeting wing structural fatigue limitations. This legislative instrument is issued under the authority of the Civil Aviation Safety Authority (CASA) and applies to aircraft operating within the Commonwealth of Australia. The AD mandates the retirement of specific components from service at or before their designated life hours, as detailed in the requirement section. The directive is applicable to aircraft with specific serial numbers and aims to address unsafe conditions identified through comprehensive fatigue tests conducted by the manufacturer. The AD supersedes previous versions, including AD/PA-36/6 Amdt 2, and is effective as of 13 July 2000. The directive is issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, and its application can be extended or restricted through subordinate instruments. This particular AD focuses on ensuring that the specified wing components are retired or replaced to maintain the airworthiness and safety of the aircraft in compliance with Australian civil aviation standards.
Key Provisions
The Civil Aviation Regulations 1998, specifically in PART 39 - 105, outline the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for Piper PA-36 (Pawnee Brave) Series Aeroplanes. This AD/PA-36/6 Amdt 3 applies to all models of the aircraft (Applicability) and mandates the retirement of specific components from service at or before certain times in service to prevent structural fatigue (Requirement). For instance, the wing carry-thru spar fittings (Part No. 97713-0097713-0297713-03) must be retired after 4100 hours for aircraft with serial numbers 7360001 and subsequent, and 7802001 and subsequent. The compliance section details when these actions must be taken, aligning with the requirement section.
Entities governed by these regulations, including aircraft operators, maintenance providers, and aviation authorities, are obligated to adhere strictly to the specified directives. This includes conducting mandatory inspections, timely replacements, and ensuring that all components meet the prescribed retirement times. Operators must maintain detailed records of inspections and actions taken to comply with the AD. Maintenance personnel must be trained to identify the affected parts and understand the retirement requirements.
Failure to comply with these airworthiness directives can result in serious consequences. The Civil Aviation Safety Authority has the authority to enforce compliance, and non-compliance can lead to severe penalties. Specifically, under the Civil Aviation Act 1988, operators can be subject to fines and potential criminal charges. The maximum penalties for non-compliance with airworthiness directives can include substantial fines up to AUD 504,000 for individuals and AUD 2,520,000 for corporations, alongside potential imprisonment terms. These stringent measures underscore the importance of strict adherence to the ADs to ensure the safety and airworthiness of the aircraft.
