Overview
The Civil Aviation Safety Regulations 1998, under Part 39 - 105, addresses the problem of ensuring aircraft safety through the issuance of Airworthiness Directives (ADs). The ADs are issued by a delegate of the Civil Aviation Safety Authority (CASA) to correct unsafe conditions identified in specific aircraft. In this particular instance, Airworthiness Directive AD/BN-2/77 Amendment 1, effective from 11/2003, targets the Pilatus Britten-Norman BN-2 series aeroplanes to rectify an issue with access panel bolts that could cause aileron travel restrictions. The directive mandates inspections and, if necessary, the replacement of specified bolts in accordance with the manufacturer's service bulletin. The overarching policy objective of these regulations is to maintain the highest standards of safety in civil aviation by providing clear and enforceable guidelines for aircraft maintenance and modifications.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, establish the scope and application of the Civil Aviation Safety Authority's (CASA) Airworthiness Directives (ADs). This particular AD, AD/BN-2/77 Amendment 1, pertains to all aircraft in the BN2, BN2A, BN2B, BN2T, BN2T-4R, and BN2T-4S series of the Pilatus Britten-Norman Islander. The AD mandates the inspection and, if necessary, replacement of access panel bolts in these aircraft to ensure compliance with safety standards. This requirement must be fulfilled in accordance with the specified instructions from the B-N Group Mandatory Service Bulletin SB 291, dated 1 May 2003. The directive also permits the use of appropriate bolts approved by the Type Certificate holder as an alternative to the A113-1D bolts listed in the bulletin. The compliance timeline stipulates inspections and actions to be completed at the next daily check after 4 June 2003 for action 6.1 and at the latest by the next major maintenance inspection for actions 6.2 and 6.3. This AD applies across the Commonwealth of Australia and was made effective on 30 October 2003, with the original issue becoming effective on 4 June 2003.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under PART 39 - 105 and the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, introduce a new Airworthiness Directive (AD) concerning the Pilatus Britten-Norman BN-2 Series Aeroplanes. This AD, identified as AD/BN-2/77 Amendment 1, addresses the issue of access panel bolts (section 1). It is applicable to all BN2, BN2A, BN2B, BN2T, BN2T-4R, and BN2T-4S series Islander aircraft (section 2). The directive mandates that these aircraft undergo an inspection in accordance with the specified actions outlined in the requirement section (section 3). It also allows for the replacement of certain bolts with approved alternatives (section 3). The compliance timeframes are set, with action 6.1 to be performed at the next daily check following 4 June 2003, unless already completed, and actions 6.2 and 6.3 to be carried out by the next major maintenance inspection (section 4).
The obligations imposed by this Airworthiness Directive on the parties it governs are quite specific. Aircraft owners or operators must ensure that the inspections and any necessary bolt replacements are carried out in compliance with the instructions provided in Service Bulletin SB 291 dated 1 May 2003. This includes adhering to the timing and methodology outlined in the directive. The directive also places a responsibility on the aircraft maintenance personnel to perform these inspections and replacements accurately and in accordance with CASA-approved procedures. Additionally, the directive requires that any changes to the aircraft's maintenance logs be properly documented and maintained, reflecting the compliance with the AD.
Failure to comply with the provisions of this Airworthiness Directive may result in significant consequences. Civil Aviation Safety Regulations 1998 outline potential civil and criminal penalties for non-compliance. The severity of these penalties can vary depending on the nature and extent of the breach. For instance, failure to perform the required inspections and bolt replacements could lead to fines or other civil penalties as stipulated by the regulations. In more severe cases, where the non-compliance results in safety hazards or accidents, criminal charges could be pursued, potentially leading to imprisonment. The exact penalties would be determined by the specific circumstances of the breach and the discretion of the enforcing authorities.
