Rotax announces revised Service Bulletin SB-912-064 R1 / SB-914-045 R1 : Periodic checking of the crankshaft journal for 912 & 914 series engines.

This revision includes the following changes:

The procedure for checking the crankshaft journal has been revised slightly; checking the oil level and purging the oil system is no longer required.

The range of affected serial numbers for non-certified (UL) engines has been updated.

Rotax has previously released SB-912-059/914-042 wherein a limited range of engines required an inspection looking for potential cracks developing in the PTO end crankshaft journal. Field experience has subsequently shown that a one time inspection is not sufficient, and therefore an ongoing periodic inspection will be necessary every 100 hours of operation and/or annually every twelve months, up to 1000 hours total engine time.

In addition, Rotax engine owners and operators should be aware the range of engine serial numbers affected has been expanded, therefore your engine serial number should be checked against those listed in the appropriate SB for your engine type (Certified or UL). Engines which have been overhauled or repaired using a new crankshaft should also have their crankshaft serial number checked against specific crankshafts listed as affected in the appropriate SB release.

Rotax has also designed a new tool that greatly simplifies this inspection requirement for engines affected. This tool is easy to use and speeds up the process of meeting compliance to the SB.

Rotax has now released revision 2 of Alert Service Bulletin ASB-912-062 / 914-044

This Mandatory Alert Service Bulletin covers the inspection of cylinder heads #2 and #3 for oil leakages into the intake port on Rotax 912 and 914 Series aircraft engines.

For this revision of the bulletin, the range of serial numbers has been expanded. Please check carefully to determine if this bulletin may now be applicable to your engine!

Also affected are cylinder heads sold from the factory as spare parts between 31 January 2013 and 28 May 2013 inclusive (Cylinder Head part no. 623682 and 623687). If you’ve purchased spare part cylinder heads of these part numbers since January 31st 2013, you must check with the supplying Rotax dealer/distributor to determine if they are affected by this latest ASB revision. If so, and the cylinder heads are still un-installed in an engine, they must be returned for replacement. If the affected cylinder heads are already installed on an engine with over 15 minutes of running time, a spark plug examination for carbon contamination from excess oil burn in accordance to the inspection requirements in the ASB (latest revision) must be performed. For more detailed information on how to perform these tasks, see the Rotax-Owner video on this subject by clicking on the link below.
