Europa-List: Rotax 912 Rocker shaft and rocker replacement SB???

[Pete Jeffers <pjeffers@talktalk.net>]

Hi all,

A long time ago Rotax issued SB-912-15 which referred to a need to replace
rocker shafts and rockers at 600hrs, on some old engines.  It allowed you to
inspect at 200 & 400hr but to replace at 600 hrs.  
I had thought that some time later an amended instruction had been issued
that allowed the 200hrs checks to be continued ad infinitum requiring
replacement only if there was a problem.

Can anyone cast any light on the whereabouts of this later instruction (if
it exists)
