FAA Issues Emergency AD for Some Rotax 912 Engines


August 29, 2012 - The FAA has issued an emergency airworthiness directive affecting certain Rotax 912 series engines. The AD requires that the pressure side fuel hose be replaced on fuel pumps with the following serial numbers:

  • 11.3117 through 11.3325 inclusive
  • 11.4036 through 11.4355 inclusive
  • 11.4516 through 11.4595 inclusive
  • 12.0251 through 12.0270 inclusive

An AD from the European Aviation Safety Agency indicates that the pressure side fuel hose on these pumps may not be manufactured to full fuel-resistant standards, which could result in the degradation of the interior of the hose and the resulting debris fouling the fuel system.

The AD becomes effective Monday, September 10. Affected owners have five flight hours from that date to make the prescribed repairs. EAA advises owners of Rotax 912-powered aircraft - type certificated and non-type-certificated - to check the AD to determine if your engine is among those affected. For more information, EAA members may call EAA Aviation Services at 920-426-5912.
