Hi john,

I believe it is your starter adaptor that is slipping. Mine produced the same symptoms when it failed. 

I think the Iskra starter damaged your starter adaptor and then the extra torque provided by the Skytec starter finished the job. This has happened to enough Cirrus owners that many shops now recommend a preemptive IRAN on the starter adaptor when changing from an Iskra to one of the newer starters.

Greetings,

I have been flying my Legacy for one year now and have accumulated 80 hours flight time.  My Legacy is equipped with a Continental IO-550-N engine.

At hour 70, I removed the ISKRA starter as a preemptive measure to preserve the starter adapter.  I replaced it with a SkyTec starter.  All has been well for the next 10 hours.  However, now at 80 hours, it appears I am getting starter slippage.  While starting the engine, I'll get a couple blades of rotation  --- and then the prop will stop turning (at a compression stroke), but it sounds as if the starter motor is continuing to turn with full power.  Stop cranking.  Then resume, I'll get a few more blades of rotation, and then the prop will stop turning, while the starter motor continues with full power. 

Is this what a failed starter adapter sounds like?  Request advice on how to proceed from other Legacy, ES, and IV, (equipped with Continental IO-550-N) owner/builders who have had similar experience and successfully resolved the issue.

Thank you,

John
