COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: This Directive applies to aircraft that have been fitted with Cessna P/N 0756005-2 top assembly, Cessna P/N 0756005-8 fuel strainer assembly or Cessna P/N 0756005-9 fuel strainer assembly shipped from Cessna between December 12, 1996 and September 5, 1997. Reports indicate that fuel strainer assemblies may have been manufactured with the fuel standpipes incorrectly installed in the assembly housing top which could allow foreign material to enter the engine fuel system resulting in loss of engine power or complete engine stoppage in flight.
Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 2 June 2000
The above AD is notified in the Commonwealth of Australia Gazette on 14 June 2000.
Overview
The Civil Aviation Regulations 1998 (CAR 1998), as enacted by the Commonwealth of Australia, play a crucial role in ensuring the safety of civil aviation operations within the country. This piece of legislation was introduced to address the need for stringent airworthiness standards and regulations to protect the safety of passengers, crew, and the general public. The CAR 1998 is administered by the Civil Aviation Safety Authority (CASA), which is responsible for enforcing and regulating compliance with the provisions outlined in the regulations. One of the key policy objectives of the CAR 1998 is to maintain the highest possible safety standards in the operation of civil aircraft, including the issuance of Airworthiness Directives (ADs) to address specific safety concerns. The ADs are legally binding instructions issued by CASA to correct unsafe conditions that may compromise the airworthiness of an aircraft. In this context, an AD may require aircraft owners or operators to take specific actions, such as inspecting, repairing, or replacing components, to ensure the continued airworthiness of the aircraft.
Scope and Application
This Airworthiness Directive (AD) applies to specific models of Cessna aircraft, namely the 170, 172, F172, FR172 and 175 series aeroplanes, that have been fitted with certain fuel strainer assemblies shipped from Cessna between December 12, 1996 and September 5, 1997. The AD is issued by the Civil Aviation Safety Authority (CASA) delegate under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) and requires specific actions to be taken to address a potential unsafe condition relating to the fuel strainer assembly. The action involves inspecting the fuel strainer assembly and measuring the standpipe tube to ensure it does not exceed a specified length, with a requirement to replace the fuel strainer top assembly if necessary. The AD must be complied with within 12 calendar months from the effective date of the directive and prior to further flight. The directive is effective as of 13 July 2000, and its details are published in the Commonwealth of Australia Gazette on 14 June 2000.
Key Provisions
The Airworthiness Directive (AD) issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) pertains to the inspection and replacement of fuel strainer assemblies in certain Cessna aeroplanes. Specifically, it applies to models 172F, 172G, 172H, 172I, 172K, 172L, 172M, 172N, 172P, 172Q, R172E (T41), R172F (T41), R172G (T41), R172H (T41), R172J, R172K, 172RG, F172F, F172G, F172H, F172K, F172L, F172M, F172N, F172P, FR172E, FR172F, FR172G, FR172H, FR172J and FR172K. The directive mandates that the aircraft fuel strainer assembly must be inspected if the aircraft was shipped with a fuel strainer assembly bearing part numbers 0756005-2, 0756005-8, or 0756005-9 between December 12, 1996 and September 5, 1997. If these parts were installed, the standpipe tube in the fuel strainer assembly must be measured to ensure it does not exceed a maximum length of 1.68 inches. If the measurement exceeds this length, the filter strainer top assembly must be replaced in accordance with the instructions provided in the Accomplishment Instructions of Cessna Single Engine Service Bulletin SEB97-9 dated November 17, 1997. Compliance with this directive must occur within 12 calendar months from the effective date of the directive and prior to further flight.
The AD imposes specific obligations on the holders of pilot licences, particularly those who are not student pilots. They are required to review the aircraft records to ascertain if the specified parts were installed. If the review confirms that these parts were not installed, a certification stating that “This Directive does not apply as no parts listed in the Cessna SEB97-9 have been fitted to this aircraft” may be entered into the aircraft records. This ensures that only those aircraft that have been fitted with the specified fuel strainer assemblies need to comply with the inspection and replacement requirements.
Failure to comply with the Airworthiness Directive may result in civil or criminal consequences. Under the Civil Aviation Act 1988, non-compliance could be considered an offence. The maximum penalties for breaches of civil aviation regulations are detailed in the Civil Aviation Regulations 1988, which can include substantial fines and imprisonment for individuals found guilty of contravening the regulations. Additionally, the AD highlights that the directive becomes effective on 13 July 2000, underscoring the urgency for compliance by the specified deadlines.
