I purchased a good quality fuel funnel which has dual filters and a high flow rate. Avgas bowser fueling nozzles are too large for Sling aircraft fuel tank caps, so the funnel will solve that issue, also ensuring clean fuel. I received a " C of A " pack from SAAA ( Sport Aircraft Association of Australia ) this week. The package is an information guide of the "Process and Framework " required to be issued with a Certificate of Airworthiness. The package also includes "Maintenance Release " forms, " Flight Test Guide "and "Flight Test Cards ".
