Pilots who fly behind engines with certain Precision Airmotive RSA-5 and RSA-10 series fuel injection servos must have their aircraft inspected and repaired by a mechanic before their next flight under an emergency airworthiness directive (AD) issued by the FAA.
The March 12 AD affects all newer-model single-engine Cessnas and some Pipers, as well as overhauled and new replacement engines, and engines that have had fuel injection gaskets replaced.
The AD comes stems from the possibility that a loose brass regulator plug could cause significant or complete engine power loss and follows a service bulletin from Precision Airmotive. In one case, an aircraft engine lost power and misfired during flight, resulting in an off-airport landing and significant damage to the airplane.
In addition to the initial inspection and repair, the AD requires repetitive inspections every 50 hours or at every engine oil change, whichever comes first.
