The FAA has issued a new airworthiness directive (AD) covering some Lycoming, Continental, and Superior Air Parts engines with certain Precision Airmotive LLC RSA–5 and RSA–10 series, and Bendix RSA–5 and RSA–10 series fuel injection servos.
This AD follows a March 2008 emergency AD that required repetitive inspections of the fuel injection servo plugs.
The newly issued AD provides an ending action and requires owners of the affected fuel injection servos plug gaskets to replace them with new gaskets by Dec. 31, 2009. This AD affects newer-model single-engine Cessnas and some Pipers, as well as some overhauled and new replacement engines.
Some engines that had fuel injection gaskets installed prior to March 2008 could also be affected.
