Overview

The Civil Aviation Regulations 1998 (CAR 1998), enacted by the Australian Parliament, govern the safety and airworthiness of aircraft operating in Australian airspace. Part 39, specifically Schedule 105, details the Airworthiness Directives, which are mandatory safety instructions issued by the Civil Aviation Safety Authority (CASA). These directives address safety concerns and ensure compliance with aviation standards. One such directive, AD/JBK 117/16, was issued to address an unsafe condition identified in Kawasaki BK 117 Series Helicopters. The directive mandates specific actions to prevent engine cowling doors from opening during flight, a critical safety measure following incidents where doors did not latch correctly during pre-flight checks. The policy objective is to mitigate potential hazards and ensure the continued safety of these aircraft in Australian airspace.

Scope and Application

The Airworthiness Directive (AD) outlined in the Civil Aviation Regulations 1998, specifically under PART 39 - 105, pertains to the Kawasaki BK 117 Series Helicopters, with serial numbers ranging from 1001 to 1123, excluding serial numbers 1007, 1085, and 1107. This AD mandates the installation of a hook system on the doors of the transmission and engine cowlings to prevent them from opening fully during flight, particularly when the fasteners are not correctly latched during pre-flight checks. The AD, issued by the delegate of the Civil Aviation Safety Authority, requires compliance with Kawasaki Service Bulletin KSB-117-154 dated 25 November 1999 and references JCAB AD TCD-5190-99. The directive stipulates that the specified action must be completed before 30 December 2000 unless already accomplished, with the directive becoming effective on 23 March 2000. This AD applies to the mentioned helicopter models within the Australian jurisdiction, overseen by the Civil Aviation Safety Authority, ensuring adherence to aviation safety standards.

Key Provisions

This Airworthiness Directive (AD), AD/JBK 117/16, issued by the Civil Aviation Safety Authority (CASA), specifically addresses the Kawasaki BK 117 Series helicopters, serial numbers 1001 through 1123, excluding serial numbers 1007, 1085, and 1107 (section 1). The directive mandates that the helicopter owners and operators comply with the actions outlined in Kawasaki Service Bulletin KSB-117-154, dated 25 November 1999, to correct an unsafe condition related to the transmission and engine cowling doors (section 2). This requirement aims to prevent the doors from opening fully during flight, which could occur if the door fasteners are not correctly latched during the pre-flight check. In terms of obligations, the AD imposes specific duties on the owners and operators of the affected helicopters. They must ensure that the installation of the hook system, as described in KSB-117-154, is completed before the deadline of 30 December 2000 (section 3). If the action has already been taken prior to this date, then the requirement is considered fulfilled. The AD became effective on 23 March 2000, meaning that compliance must be achieved by the stated deadline, unless the necessary action has already been completed. Failure to comply with this Airworthiness Directive can result in serious consequences. While the specific penalties are not detailed in the text, non-compliance with ADs generally can lead to enforcement actions by CASA. These actions may include fines, grounding of the aircraft, and other administrative penalties. In severe cases, non-compliance could result in criminal charges, especially if the failure to adhere to the directive leads to an accident or incident that endangers safety. The maximum penalties for such breaches can vary but may include substantial fines and imprisonment, depending on the circumstances and the severity of the non-compliance.
