Overview
The Civil Aviation Regulations 1998, as amended by the Airworthiness Directive AD/BN-2/66 Amendment 1, was enacted to address the safety concerns arising from cracks in the nose wheel steering aluminium drive-rings of Pilatus Britten-Norman BN-2 Series Aeroplanes, specifically the BN2, BN2A, BN2B, and BN2T Islander models. This directive was issued by the Civil Aviation Safety Authority (CASA) to mandate corrective actions in response to reports of these cracks. The overarching policy objective of this legislation is to ensure the safety and airworthiness of aircraft operating within Australia by enforcing necessary maintenance and operational protocols.
The Airworthiness Directive AD/BN-2/66 Amendment 1 requires the installation of a steel drive-ring (part number NB-41-193) and mandates inspections and actions as outlined in the Britten-Norman Mandatory Service Bulletin BN2/SB.214 Issue 2. The directive was published in the Commonwealth of Australia Gazette on 12 July 2000 and became effective on 10 August 2000, necessitating compliance within 100 hours of time in service after this date or at subsequent intervals not exceeding 100 hours until the specified corrective action is completed.
Scope and Application
This Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 applies specifically to the Pilatus Britten-Norman BN-2 Series Aeroplanes, including models BN2, BN2A, BN2B, and BN2T Islander aircraft. The directive mandates corrective actions to address a safety issue identified with the nose wheel steering drive-ring of these aircraft. The requirement for compliance involves following the instructions outlined in the Britten-Norman Mandatory Service Bulletin BN2/SB.214 Issue 2. For aircraft that have not yet undergone the initial inspection, this directive necessitates action within 100 hours of time in service following 10 August 2000. Thereafter, the required inspections must be carried out at intervals not exceeding 100 hours of time in service until a steel drive-ring (part number NB-41-193) is installed. The AD applies throughout the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA), which ensures that all necessary safety measures are adhered to in the operation of these aircraft.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39, specifically section 105, mandates the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to address safety issues with aircraft. The latest AD concerning the Pilatus Britten-Norman BN-2 Series Aeroplanes, identified as AD/BN-2/66 Amendment 1, mandates particular actions to ensure the safety of the aircraft (section 105(1)). This AD specifically applies to the BN2, BN2A, BN2B, and BN2T Islander aircraft models (applicability section).
The AD requires that maintenance actions be performed in line with the Britten-Norman Mandatory Service Bulletin BN2/SB.214 Issue 2 (requirement section). The initial inspection must be completed within 100 hours of service time after the AD's effective date of 10 August 2000. Following this initial inspection, further inspections must occur at intervals not exceeding 100 hours of service time, until a steel drive-ring (part number NB-41-193) is installed (compliance section). This AD was issued to rectify a previously noted issue regarding cracks in the nose wheel steering aluminium drive-rings.
Entities governed by this AD must ensure that the required inspections and actions are performed by qualified personnel within the specified timeframes. They must adhere to the instructions set out in the Britten-Norman Mandatory Service Bulletin BN2/SB.214 Issue 2 to maintain the airworthiness of the affected aircraft models. Failure to comply with the AD may result in the aircraft being deemed unairworthy, leading to potential grounding and legal repercussions.
Breaching the requirements of this AD may result in severe consequences. Non-compliance with the AD could lead to the aircraft being deemed unsafe for operation, resulting in potential grounding or refusal of airworthiness certification. This could have significant financial and operational implications for the aircraft owner or operator. Additionally, CASA has the authority to enforce penalties, including fines and other legal actions, against entities that fail to comply with the airworthiness directives issued under the Civil Aviation Regulations 1998.
