COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: This directive was issued to address reports of cracking and break up of certain air filter elements. The defects resulted from evidence of manufacturing errors in filters produced during the period January 1997 though September 1998.
This amendment adds the PA-28S-160 and PA-28S-180 models and PA-28-151/161 aircraft modified in accordance with STC SA2946SO to the aircraft applicable and adds a terminating action.
The original issue of this Airworthiness Directive became effective on 9 September 1999.

Delegate of the Civil Aviation Safety Authority 30 June 2000
The above AD is notified in the Commonwealth of Australia Gazette on 12 July 2000.
Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide a comprehensive regulatory framework governing all aspects of civil aviation in Australia. One of the critical components of these regulations is Part 39, which outlines the requirements for maintaining the airworthiness of aircraft. Under this Part, the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) to address safety concerns and ensure compliance with safety standards. For instance, AD/PA-28/95 Amdt 1, issued on 30 June 2000 and notified in the Commonwealth of Australia Gazette on 12 July 2000, pertains specifically to Piper PA-28 Series Aeroplanes. This directive was introduced to address the problem of cracking and break up of certain air filter elements, which were found to result from manufacturing errors in filters produced between January 1997 and September 1998. The policy objective behind this directive was to mitigate potential safety risks by requiring inspections and replacements of the affected air filters, thereby enhancing the overall safety and airworthiness of the specified aircraft models.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, establishes a specific Airworthiness Directive (AD) applicable to Piper PA-28 series aeroplanes with certain engine air filters. This directive applies to aircraft models PA-28-140, -150, -160, -180, -181, -235, -201T, -28R-201T, -28S-160, and -28S-180 of all serial numbers, as well as to PA-28-151 and PA-28-161 aircraft modified in accordance with Supplemental Type Certificate (STC) SA2946SO, which are equipped with specific Puralator (FACET) air filters identified by certain brand names and part numbers. The directive mandates the inspection and replacement of these air filters to address safety concerns arising from manufacturing defects that led to cracking and break up of the filters. The compliance timeframes for inspections and replacements are clearly outlined, ensuring that affected aircraft are brought into compliance in a timely manner. The directive extends its application across the Commonwealth of Australia, as it is issued under the authority of the Civil Aviation Safety Authority (CASA) and published in the Commonwealth of Australia Gazette, thereby binding all relevant entities and individuals operating within the Australian jurisdiction.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish a Schedule of Airworthiness Directives, which include specific requirements for maintaining the airworthiness of aircraft. This particular section concerns the Piper PA-28 Series Aeroplanes and mandates specific actions to address identified safety issues. The directive issued, AD/PA-28/95 Amendment 1, targets the engine air filter for certain models of Piper PA-28 aircraft (section 1). The applicability section (section 2) specifies the aircraft models and serial numbers that are subject to this directive, including PA-28-140, -150, -160, -180, -181, -235, -201T, -28R-201T, -28S-160, and 28S-180, as well as PA-28-151 and PA-28-161 aircraft modified with Supplemental Type Certificate (STC) SA2946SO, if equipped with a specific air filter. The requirement section (section 3) mandates that these air filters be inspected and, if necessary, replaced with an approved air filter, ensuring that any replacement other than the specified Puralator (FACET) P/N 638873 filter constitutes a terminating action for this directive.
The obligations imposed by this Airworthiness Directive are clear and stringent. Aircraft owners or operators must ensure that the applicable air filters are inspected in accordance with specified service bulletins (section 3.1). This inspection must occur either at the next engine air inlet filter element inspection or within 25 hours of the directive's effective date, whichever comes first (section 3.2). For filters already installed, the inspection must occur at the next periodic inspection or within 12 months from the directive's effective date (section 3.3). Any spare filters must be inspected before being installed in an engine (section 3.4). These requirements are designed to ensure that the identified safety issues are promptly addressed, maintaining the airworthiness of the affected aircraft.
Failure to comply with this Airworthiness Directive can result in serious consequences. The directive is issued under the authority of the Civil Aviation Safety Authority (CASA) and is legally binding. Non-compliance could potentially lead to the grounding of the aircraft until the required actions are taken. While the specific penalties are not detailed in the text, non-compliance with CASA directives generally can result in enforcement actions, which may include fines, legal action, and other regulatory penalties. The intent of the directive is to prevent unsafe conditions and ensure the continued airworthiness of the aircraft, underscoring the seriousness of adherence to these requirements.
