Supply Chain: Periodic Testing of Avgas
The objective of this Bulletin is to improve the control requirements for Avgas grades at supply terminals and airports to ensure that the product meets the specification at the point of delivery. This Bulletin relates to a need to carefully manage those Avgas properties that may deteriorate when kept in tank for extended periods, or where certain product properties are already close to specification limits which may limit the remaining storage life of the product.
This changes previous guidance that Periodic Testing has to be carried out after 6 months of inactivity. For low flash-point product such as Avgas, more frequent testing may be required to ensure the product remains on-specification.
