AD/BN-2/68 - Rudder Lower Hinge Doubler

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve to regulate various aspects of civil aviation, including airworthiness directives that ensure aircraft safety. One such directive, AD/BN-2/68, pertains specifically to the Pilatus Britten-Norman BN-2 Series Aeroplanes, covering models BN2, BN2A, BN2B, and BN2T Islander aircraft. This directive was introduced to address reports of damage to the rudder lower hinge. It mandates the installation of a doubler at the left and right side of the rudder lower hinge bracket to mitigate this risk, as specified in Britten Norman Mandatory Service Bulletin BN2/SB.240. The directive became effective on 17 June 1999, with compliance required before 17 July 1999, aiming to enhance the safety of the aircraft by preventing potential rudder failures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39, applies to aircraft operators and owners of the Pilatus Britten-Norman BN-2 series, which includes the BN2, BN2A, BN2B, and BN2T Islander models. The regulation mandates compliance with the Airworthiness Directive AD/BN-2/68, which pertains to the installation of a rudder lower hinge doubler to mitigate damage to the rudder lower hinge, as reported by the manufacturer. This directive applies nationally across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority (CASA). The requirement to comply with the directive applies to all BN-2 series aircraft in operation before the effective date of the directive, 17 June 1999. Subordinate instruments may further detail the specific compliance measures and enforcement mechanisms, but the primary requirement remains the installation of the rudder lower hinge doubler as per the Britten Norman Mandatory Service Bulletin BN2/SB.240.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105 (Section 39.105), pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives for the Pilatus Britten-Norman BN-2 series aeroplanes, specifically addressing issues with the rudder lower hinge. The directive, AD/BN-2/68, requires action in accordance with Britten Norman Mandatory Service Bulletin BN2/SB.240, which mandates the installation of a rudder lower hinge doubler to mitigate reported damage. This directive applies to BN2, BN2A, BN2B, and BN2T Islander aircraft. The compliance deadline was set before 17 July 1999, and the directive became effective on 17 June 1999. The obligations imposed by this directive are clear and specific, requiring operators of BN2, BN2A, BN2B, and BN2T Islander aircraft to adhere to the installation of the rudder lower hinge doubler as outlined in Britten Norman Mandatory Service Bulletin BN2/SB.240. The directive ensures that this modification is made to all applicable aircraft before the specified compliance date to maintain airworthiness and safety standards. Operators must ensure that all required actions are documented and verified by CASA-approved personnel. Failure to comply with the provisions of this airworthiness directive can result in severe consequences. The Civil Aviation Regulations 1998 outline potential penalties for non-compliance, which may include both civil and criminal liabilities. Civil penalties can include fines, while criminal penalties can result in imprisonment. The exact penalties are not specified in the directive but are in line with the broader civil aviation regulatory framework, which may include substantial fines and/or imprisonment depending on the severity and impact of the non-compliance. Ensuring adherence to the directive is crucial to avoid these repercussions and maintain the safety and regulatory compliance of the aircraft in question.
