Overview
The Civil Aviation Regulations 1998, under Part 39 - 105, includes the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which aims to ensure the continued airworthiness of aircraft and aeronautical products. This legislative instrument was enacted to address safety concerns and mitigate risks associated with aviation operations. The authority to enact such regulations lies with the Civil Aviation Safety Authority, which is responsible for ensuring compliance with safety standards to protect the public and enhance the safety of civil aviation. The policy objective of these directives is to mandate specific actions to correct identified unsafe conditions, ensuring that aircraft meet the necessary safety standards and are maintained in a safe operational condition.
The Airworthiness Directive AD/JBK 117/18, issued under subregulation 39.1 (1) of CAR 1998, is one such directive aimed at addressing an unsafe condition in Kawasaki BK 117 Series Helicopters. The directive mandates specific actions, such as affixing placards, revising the flight manual, and installing specific caps on pressure ratio switch elbows, to ensure the safe operation of these helicopters. This directive was issued due to a potential limitation in engine power during single engine operations when the heating or environmental control system is in use, thereby necessitating corrective measures to maintain airworthiness and safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all Model BK 117 B1 or B2 helicopters equipped with LTS101-750B-1 engines that have an acceleration schedule biasing system, or those with engines identified by a suffix "B" after the engine serial number, or engines fitted with an FCU P/N 4-301-413-02, -03 or -04. This directive is issued under the authority of the Civil Aviation Safety Authority (CASA) and is applicable nationwide within Australia. The primary aim of this Airworthiness Directive is to ensure the safe operation of these specified helicopters by mandating certain actions to address a potential unsafe condition. Compliance with this directive must be achieved by adhering to the specified requirements and timelines, which include affixing placards, revising the Limitation section of the JCAB approved flight manual, and installing a specific cap on the pressure ratio switch elbow. The directive became effective on 20 May 2000, and actions must be completed before subsequent flights and within specified timeframes following this date. This Airworthiness Directive is subject to further amendments and interpretations through subordinate instruments, ensuring its ongoing relevance and effectiveness in maintaining aviation safety standards.
Key Provisions
The Airworthiness Directive (AD) AD/JBK 117/18, issued under section 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998), mandates specific actions to ensure the safety of Kawasaki BK 117 Series Helicopters equipped with certain engine types (section 1). The AD applies to all Model BK 117 B1 or B2 helicopters that are fitted with LTS101-750B-1 engines equipped with an acceleration schedule biasing system, or where the engine is identified by a suffix "B" after the engine serial number, or engines fitted with FCU P/N 4-301-413-02, -03, or -04 (section 2). The required actions include affixing placards as per Kawasaki SB KSB-117-161 paragraph 9(1), revising the Limitation section of the JCAB approved flight manual to include specific wording, and installing a cap on the pressure ratio switch elbow (section 3). Notably, altitude limitation placards must remain in place until further notice (Note 1), and JCAB AD TCD-5097A-99 refers (Note 2).
This AD imposes several obligations on the operators of the specified helicopters. Firstly, operators must affix the required placards as directed, ensuring compliance with the instructions provided in paragraph 9(1) of Kawasaki SB KSB-117-161. Secondly, operators must revise the Limitation section of their JCAB approved flight manual by inserting a copy of this Directive facing page 2.20. Finally, operators must install the specified cap on the pressure ratio switch elbow and remove the placard restricting Heater/ECS operation. It is critical that these actions are carried out in a timely manner to maintain the airworthiness of the aircraft.
Failure to comply with this AD can result in significant consequences. While the specific penalties are not outlined in the text, under the Civil Aviation Regulations 1998, non-compliance with Airworthiness Directives can lead to severe civil or criminal penalties. In the case of civil penalties, the maximum fine for contravening an AD can be substantial, often reaching up to $222,200 for corporations and $44,440 for individuals, depending on the severity and frequency of the breach. Additionally, non-compliance may result in criminal charges, potentially leading to imprisonment, particularly if the non-compliance results in a significant risk to safety. These potential penalties underscore the importance of adhering to the requirements set out in the AD.
