Oil Analysis / Trend Monitoring

[Charlie Smith]

Trying to start a part 135 single pilot operation (IFR) with a Cirrus 2020 SR22T and hoping I can get some help.

I'm looking for help with FAR 135.421. We currently use Blackstone for oil analysis and have snapshots of engine data but are there any existing maintenance manuals or approved providers we could get services from rather than build the wheel ourselves?

Any help is appreciated. Thank you!

(c) For each single engine aircraft to be used in passenger-carrying IFR operations, each certificate holder must incorporate into its maintenance program either:

(1) The manufacturer's recommended engine trend monitoring program, which includes an oil analysis, if appropriate, or

(2) An FAA approved engine trend monitoring program that includes an oil analysis at each 100 hour interval or at the manufacturer's suggested interval, whichever is more frequent.​

Any help is appreciated.

Have you contacted TCM support or Cirrus support yet? Without any manuals, I believe the oil analysis is in CH 5 or 6 of the engine service manual. I don't know Cirrus, but I seem to recall a TCM document that was acceptable for the engine trend requirement for .421??
