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 revokes Airworthiness Directive (AD) AD/PC-12/28 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.
Pilatus PC-12 Series Aeroplanes
AD/PC-12/28
Amdt 1
Cargo Door End Frame Lightening Holes 13/2001
Applicability: All PC-12 and PC-12/45 aircraft with manufacturers serial numbers MSN 301 through MSN 370.
Requirement: Inspect in accordance with Pilatus Aircraft Service Bulletin No. 52-004 Revision 1.
Note: Switzerland FOCA AD HB 2001-389R1 refers.
Compliance: Within 3 calendar months after the effective date of this Directive, unless already accomplished.
This amendment becomes effective on 27 December 2001.

Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the regulation and safety of civil aviation within Australia. Enacted by the Commonwealth of Australia, this legislation aims to ensure the safety and airworthiness of aircraft operating within the nation's airspace. One of the key components of this regulation is the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes Airworthiness Directive AD/PC-12/28 concerning the Pilatus PC-12 Series Aeroplanes. This directive was introduced to address safety concerns related to cargo door end frame lightening holes on specific models of Pilatus PC-12 aircraft, aiming to prevent potential cracking and other unsafe conditions that could compromise flight safety. The policy objective is to mandate corrective actions to ensure that these aircraft meet the required safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (AD) to ensure the safe operation of aircraft. In this instance, AD/PC-12/28 Amendment 1 pertains to Pilatus PC-12 Series Aeroplanes, specifically those with manufacturers serial numbers ranging from MSN 301 to MSN 370, including the PC-12 and PC-12/45 variants. This directive applies to all aircraft within the specified serial number range and requires an inspection in accordance with Pilatus Aircraft Service Bulletin No. 52-004 Revision 1, which addresses cargo door end frame lightening holes to prevent potential cracking. Compliance with this AD is mandatory and must be completed within three calendar months from the effective date, which is 27 December 2001, unless the inspection has already been performed. This AD is part of a broader framework under the Civil Aviation Regulations 1998 and is applicable across the Commonwealth of Australia, reflecting the national regulatory standards for civil aviation safety.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, govern the Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). Under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, a CASA delegate can revoke an existing AD and issue a new one if it is deemed necessary to address an unsafe condition (section 1). In this case, AD/PC-12/28 has been revoked and replaced by a new AD concerning the Pilatus PC-12 Series Aeroplanes, particularly focusing on the cargo door end frame lightening holes (section 2). The new directive applies to all PC-12 and PC-12/45 aircraft with manufacturers serial numbers MSN 301 through MSN 370 (section 3).
The AD mandates that an inspection be carried out in accordance with Pilatus Aircraft Service Bulletin No. 52-004 Revision 1 (section 4). This inspection is necessary to identify and rectify any potential issues with the cargo door end frame lightening holes, which, if left unaddressed, could lead to cracking at the edges of the unflanged holes (section 5). The directive references the Swiss Federal Office for Civil Aviation (FOCA) AD HB 2001-389R1 for additional context (section 6).
The obligation imposed on the relevant parties, such as aircraft owners, operators, and maintenance providers, is to conduct the specified inspection within three calendar months from the effective date of the directive, unless the inspection has already been completed (section 7). Failure to comply with the directive may result in the aircraft being deemed unairworthy, which could lead to grounding and further regulatory actions (section 8).
In the event of non-compliance with the AD, there could be severe consequences, including potential enforcement actions by CASA. While the Civil Aviation Regulations 1998 do not explicitly state the penalties for non-compliance with ADs, breaches of regulations under the Civil Aviation Act 1988 can result in significant fines and imprisonment for individuals, as well as substantial fines for corporations. The maximum penalty for a serious breach can be up to $1,100,000 for individuals and $5,500,000 for corporations (section 9).
