7.1 Petroleum, Oils, Lubricants and Allied Products (POLAP) refers to the fuels, oils, hydraulic fluids, greases, corrosion inhibitors and coolants that are used within or applied to aircraft. POLAP requirements for Defence aircraft, and the approval of such products, are considered during the aircraft (and/or engine) type certification and are documented within the certified type design. Approved POLAP is detailed in either the Type Certificate Data Sheet (for aircraft and/or aircraft engines), or in associated aircraft and engine Instructions for Continued Airworthiness (ICA), including the aircraft flight manual.
7.2 Consequently, the Authority does not prescribe airworthiness design requirements for POLAP. Compliance with the requirements for establishing the approved suite of POLAP for an aircraft/engine per the recognised NAA/MAA Airworthiness Codes at Section 1 Chapter 2 is appropriate.
7.3 Importantly, access to approved POLAP to support operations may have significant impacts on capability and interoperability. When seeking to acquire a Defence aircraft or aircraft engine, the responsible project office should engage with the Fuel Services Branch (FSB) to ensure that approved POLAP will be available for all proposed operational scenarios.
7.4 In-service management requirements for POLAP are documented in DEF(AUST) 206 Petroleum, Oils and Lubricants Handbook and DEF(AUST) 5695 Petroleum, Oils and Lubricants Manual. Further advice associated with management of POLAP for Defence aviation use can be provided by the FSB - Product Stewardship.
