Fokker Model F27 and F28; Gulfstream Model G-1159 and G-IV; Lockheed L-1011; and
McDonnell Douglas Model DC-9, DC-9-80, DC-10 and MD-11;
Requirement: 1. Perform a one time inspection of the water heater or coffee maker, in accordance with Nordskog Industries Service Bulletin SB-93-35, to determine if a NUPRO pressure relief valve having part number SS-2C4-65 has been installed.
2. If a NUPRO pressure relief valve part number SS-2C4-65 has been installed then either:
- replace the pressure relief valve with a new, improved NUPRO pressure relief valve part number SS-CHF2-65, or
b. deactivate the water heater or coffee maker and install a placard stating `Not to be used’.
3. NUPRO pressure relief valves part number SS-2C4-65, held as spares are not to be fitted to water heaters or coffee makers identified in Nordskog Industries Service Bulletin SB-93-35 and these water heaters or coffee makers are not to be fitted to an aircraft as replacement items, if a NUPRO pressure relief valve part number SS- 2C4-65 is installed.
Note: FAA AD 94-14-03 Amdt 39-8955 refers.
Compliance: 1 - Prior to 15 September 1995.

SCHEDULE OF AIRWORTHINESS DIRECTIVES
2 - Prior to further flight.
3 - With effect 15 September 1994.
Background: The FAA received a report of injuries to cabin crew members that resulted from an explosion of a galley water heater caused by the failure of the pressure relief valve. Although that heater was fitted with an integral check valve, the FAA has determined that the possibility exists for the pressure relief valve to fail in other water heaters or coffee makers without the integral check valve.
Compliance with this Directive will decrease the likelihood of galley water heaters and coffee makers exploding, causing either injuries to passengers and crew or structural damage to the aircraft.
Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address the need to ensure the safety of civil aviation by setting forth detailed regulations. Part 39, which encompasses the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes provisions for the mandatory inspection and modification of specific electrical equipment such as Nordskog water heaters and coffee makers. This legislation was introduced to mitigate the risk of pressure relief valve failure in certain water heaters and coffee makers, which could result in explosions causing injuries to passengers and crew, or structural damage to the aircraft. The policy objective, as stated, is to enhance aviation safety by reducing the likelihood of such incidents through the enforcement of specific compliance measures.
Scope and Application
The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies specifically to Nordskog water heaters and coffee makers without an integral check valve, as identified in Nordskog Industries Inc Service Bulletin SB-93-35 dated 21 October 1993. These directives mandate a one-time inspection to determine if a specific NUPRO pressure relief valve part number SS-2C4-65 has been installed. The applicability extends to these devices manufactured between January 1990 and July 1991 or serviced since January 1990. Notably, these water heaters and coffee makers are installed in a variety of aircraft series including Airbus, Boeing, Canadair, Dassault-Aviation, de Havilland, Fokker, Gulfstream, Lockheed, and McDonnell Douglas models, among others. Compliance with these directives is crucial, requiring the replacement of the specified pressure relief valve with a new, improved model or deactivation of the water heater or coffee maker and installation of a placard stating ‘Not to be used’. Additionally, spare NUPRO pressure relief valves part number SS-2C4-65 must not be fitted to these devices, and these devices must not be used as replacement items on aircraft if they contain the specified pressure relief valve. These directives aim to mitigate the risk of explosions caused by pressure relief valve failures, thereby preventing potential injuries to passengers and crew and structural damage to the aircraft.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 107, outlines the requirements for airworthiness directives, such as AD/ELECT/64, which pertains to Nordskog water heaters and coffee makers. This directive applies to water heaters and coffee makers, without an integral check valve, manufactured by Nordskog Industries Inc between January 1990 and July 1991, or serviced since January 1990 (section 107). These appliances are known to be installed in various aircraft models, including Airbus, Boeing, Canadair, Dassault-Aviation, de Havilland, Fokker, Gulfstream, Lockheed, and McDonnell Douglas series.
Under section 107, the key requirements of AD/ELECT/64 include conducting a one-time inspection to determine if a NUPRO pressure relief valve with part number SS-2C4-65 has been installed in the Nordskog water heater or coffee maker. If the specified valve is present, the directive mandates either replacing it with a new, improved NUPRO pressure relief valve with part number SS-CHF2-65 or deactivating the appliance and installing a placard stating ‘Not to be used’ (section 107(1)). Furthermore, spare NUPRO pressure relief valves with part number SS-2C4-65 must not be fitted to these appliances, and appliances fitted with this valve must not be used as replacements in aircraft (section 107(3)).
The obligations imposed by this directive require aircraft operators to ensure compliance with the airworthiness directive. This includes conducting the necessary inspection and taking corrective action as specified in the directive. The directive stipulates that compliance must be achieved before 15 September 1995, and any subsequent flight must adhere to the directive's requirements (section 107(1)-(3)). Additionally, the directive came into effect on 15 September 1994.
Failure to comply with the airworthiness directive may result in serious safety consequences, including potential injuries to passengers and crew or structural damage to the aircraft due to an explosion of the galley water heater. The directive references FAA AD 94-14-03 Amdt 39-8955, indicating a coordinated effort with the Federal Aviation Administration to address this safety issue. The consequences of non-compliance could potentially involve civil penalties under the Civil Aviation Act 1988, including fines, and criminal charges if the non-compliance results in harm or damage. The exact penalties are not specified in the directive but are generally determined by the severity of the breach and the impact on aviation safety.
