The engine manufacturer orderes by the bulletins SB-912-070 R1 and SB-912-070UL, inspection and / or replacement of the valve push rod assy., and rocker arm. Due to deviations in the manufacturing of the valve push rod assy., partial wear on the rocker arm ball socket may occur. This wear might lead to a rocker arm cracking / fracture which consequence may lead to a malfunction of the valve train. Possible effect are rough engine running or an unusual engine operating behaviour.
Clarification of engine idle RPM, added information on throttle lever operation, added information to section 7 and added supplements No. 25 and 26 into List of Supplements in Section 9.
When the Dynon SkyView system and the radio station are switched on, the symbol RX on the radio station display may flash or stay lit even if the radio station does not receive transmission of other radio stations.The characteristic sound of open SQUELCH, or other disturbing noises (tones) are heard in the headphones.It is not possible to correct this interference by reducing the sensitivity of the radio station to the minimum level.The interference is caused by the SV-250-GPS antennas.
