COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Pilatus Britten-Norman BN-2 Series Aeroplanes
AD/BN-2/44 Main Undercarriage Leg - Conversion 1/80
Applicability: All models.
Document: 1. Britten Norman SB No. BN-2/SB.134; and
2. A.P. Precision Hydraulics SB No. 32-277. Compliance: Before 1 June 1980.
Background: A number of undercarriage leg assemblies P/N AIR83002 not cleared for installation on BN-2A aircraft must be converted to the original design standard in accordance with the referenced Service Bulletin. Failure to promptly carry out the conversion may result in transmission of higher than normal landing loads to the airframe.
Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, include specific regulations to ensure the safety and airworthiness of aircraft operating within Australian airspace. One such regulation pertains to the Pilatus Britten-Norman BN-2 Series Aeroplanes, addressed in Airworthiness Directive AD/BN-2/44. This directive was introduced to address a critical safety issue concerning the main undercarriage leg assemblies of BN-2A aircraft. Specifically, undercarriage leg assemblies P/N AIR83002, which were not cleared for installation, must be converted to the original design standard to prevent the transmission of higher than normal landing loads to the airframe, which could compromise the structural integrity of the aircraft.
The directive, issued by the Civil Aviation Safety Authority (CASA), mandates compliance with the referenced service bulletins from Britten Norman and A.P. Precision Hydraulics, ensuring that all conversions are completed before 1 June 1980. The policy objective behind this directive is to maintain the highest safety standards for all aircraft operating within Australian airspace, thereby protecting both the aircraft and those on board from potential hazards associated with non-compliant undercarriage leg assemblies.
Scope and Application
The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the conversion of certain undercarriage leg assemblies on Pilatus Britten-Norman BN-2 series aeroplanes. This applies to all models of the BN-2 series, demanding compliance with the referenced Service Bulletins, namely Britten Norman SB No. BN-2/SB.134 and A.P. Precision Hydraulics SB No. 32-277. The directive is particularly pertinent for undercarriage leg assemblies P/N AIR83002 that were manufactured before 1 June 1980 and were not cleared for installation on BN-2A aircraft. Failure to convert these parts may result in higher than normal landing loads being transmitted to the airframe, which could compromise the aircraft's safety. This regulation is applicable across the Commonwealth of Australia, extending CASA's jurisdiction over the civil aviation safety measures that must be adhered to by all relevant operators and owners of the specified aircraft models.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, include a directive for Pilatus Britten-Norman BN-2 Series aeroplanes. This directive, identified as AD/BN-2/44, pertains to the conversion of the main undercarriage leg. The directive applies to all models of the BN-2 series aeroplanes (Section 1). The conversion must be performed in accordance with two service bulletins: Britten Norman SB No. BN-2/SB.134 and A.P. Precision Hydraulics SB No. 32-277 (Section 2). It is crucial that this conversion is completed before 1 June 1980 to ensure compliance (Section 3). The directive highlights the necessity of converting undercarriage leg assemblies, specifically those with part number AIR83002, which were not cleared for installation on BN-2A aircraft. These assemblies must be converted to meet the original design standards as outlined in the referenced service bulletins. Non-compliance with this directive can result in the transmission of higher than normal landing loads to the airframe, posing a significant safety risk.
Entities and individuals governed by these regulations are obligated to ensure that the conversion of the undercarriage leg assemblies is performed as specified. This involves following the detailed instructions provided in the service bulletins to accurately convert the parts in question. The directive emphasises the importance of adhering to the specified timelines to mitigate safety risks associated with the use of non-compliant parts. It is imperative that all stakeholders, including aircraft operators and maintenance personnel, are fully aware of and comply with these obligations to maintain the airworthiness of the aircraft.
Failure to comply with the requirements set out in this airworthiness directive may result in serious consequences. While specific penalties are not detailed in the legislative instrument, non-compliance with CASA directives generally can lead to enforcement actions. These may include fines, suspension or revocation of airworthiness certificates, and other regulatory actions. The severity of the penalties can vary depending on the nature and extent of the non-compliance, but the overarching goal is to ensure that all aircraft maintain the highest safety standards. Therefore, it is crucial for all parties involved to take this directive seriously and to ensure full compliance to avoid any adverse outcomes.
