AD Issued on Rotax 912A engines 2011-14-09
AD Superceded for Rotax 912A Magneto Flywheel Hub.
Dimona, Super Dimona, Katana, AMT-200 and Scheibe SF-25C are some of the airframes included in AD 2011-14-09. Prior AD was 2011-11-03.
This is in response to the discovery of hardened material washers being found on the magneto flywheel hub. Failure or cracking of the washers could result in ignition problems, and perhaps engine failure.
This AD requires within the next 10 hours time-in-service, or four months of the effective date, replacement of the washers and gasket rings. There is no change in Part Numbers, following the Accomplishment Instructions in Rotax Aircraft Engines Mandatory Service Bulletin SB-912-058 and SB-914-041 (same document), dated April 15, 2011.
The effective date of this AD is July 25, 2011.
