COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: The RLD has received a report of an aircraft Inventum DR6 galley water heater exploding during an overheat test in a maintenance facility. Investigation revealed that the heater did not have a pressure relief valve or 3-phase safety devices installed. Since this condition may exist on other similar Inventum water heaters, this Directive is issued to prevent explosions of water heaters and subsequent injuries to passengers or cabin crew members.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, is a comprehensive piece of legislation aimed at ensuring the safety and regulation of civil aviation within Australia. Specifically, Part 39 - 107 of these Regulations, issued by the Civil Aviation Safety Authority, addresses airworthiness directives to mitigate potential safety risks. One such directive, AD/ELECT/62, pertains to the inspection and modification of Inventum Model DR1 and DR6 series water heaters installed in certain aircraft, such as Boeing 727 and 737, McDonnell Douglas DC-9, and Fokker F28 models (excluding Mk. 1000). This directive was introduced to address the potential hazard of these water heaters exploding due to the absence of critical safety components, specifically pressure relief valves and 3-phase safety devices. The policy objective of this directive is to prevent such incidents and ensure the safety of passengers and crew by mandating inspections and necessary modifications or deactivations of the affected water heaters.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 107 and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, apply specifically to Inventum Galley Products Division Model DR1 and DR6 series Water Heaters with particular part numbers and serial numbers listed in the Inventum Alert Service Bulletins dated 6 December 1993. These water heaters are known to be installed in, but not limited to, Boeing 727 and 737, McDonnell Douglas DC-9, and Fokker F28 aircraft (excluding Mk. 1000). The directive mandates a one-time inspection of these water heaters to ensure that they are equipped with a pressure relief valve and two 3-phase safety devices as specified in certain Inventum Service Bulletins. If these safety components are not present, the directive requires either the removal of the water heater and installation of a modified version or deactivation of the heater with a placard indicating it is not to be used. Additionally, Inventum Model DR1 and DR6 water heaters are not permitted as replacement items unless they are modified according to the referenced Inventum Service Bulletins. The directive's compliance requirements necessitate inspections prior to 1 July 1994 and before further flights after the initial inspection, with the directive coming into effect on 28 April 1994.
Key Provisions
The Civil Aviation Regulations 1998, as detailed in Part 39 - 107, include specific Airworthiness Directives (AD) concerning the safety of electrical equipment in aircraft. Specifically, AD/ELECT/62 pertains to Inventum Water Heaters, which are used in several aircraft models including Boeing 727 and 737, McDonnell Douglas DC-9, and Fokker F28 (excluding Mk. 1000). The directive applies to Inventum Galley Products Division Model DR1 and DR6 series Water Heaters, as identified by specific part numbers and serial numbers listed in Inventum Alert Service Bulletins dated 6 December 1993.
The directive mandates a one-time inspection of all affected water heaters to ensure compliance with certain safety requirements. Firstly, inspectors must verify if a pressure relief valve has been installed in accordance with Inventum Service Bulletins dated 8 July 1976, 28 September 1977, or 6 December 1993. Secondly, inspectors must check if two 3-phase safety devices have been installed as per Inventum Service Bulletins dated 7 July 1977, 18 January 1978, 16 February 1978, or 6 December 1993. If either of these safety components is missing, the directive stipulates that the water heater must either be removed and replaced with a modified version or deactivated and marked with a placard stating "Not to be used". Additionally, Inventum Model DR1 and DR6 water heaters are not to be used as replacement items unless they have been modified according to the referenced service bulletins.
The obligations imposed by this directive are stringent and demand compliance from aircraft operators and maintenance personnel. Aircraft operators must ensure that all inspections are conducted prior to 1 July 1994 and that any necessary modifications or deactivations are completed before further flights post-inspection. This directive also clarifies that it takes effect on 28 April 1994, and any non-compliance could have serious safety implications. Failure to adhere to these requirements can result in severe consequences, including potential explosions and injuries to passengers and crew.
Breaching the provisions of this Airworthiness Directive can lead to significant civil and criminal penalties. The Civil Aviation Safety Authority (CASA) has the authority to impose fines and other sanctions on individuals and entities found in violation of the regulations. For instance, non-compliance can lead to hefty fines and, in severe cases, criminal charges. The exact penalties may vary depending on the severity and impact of the breach but can include substantial financial penalties and, in extreme cases, imprisonment for those found criminally liable.
