We recieved the following question:
I currently have an IAA inspector who believes that the latest operations manual for the O-360-J2A engine is 60297-12-6 and was revised in February 2014. I was under the impression that SL114AW is still in force and the latest revision of the operator's manual is 60297-12-5 last revised in 2009. Can you please let me know what the situation is?
We contacted the OEM and they reported:
You are correct about the last revision of the Operator’s Manual is 60297-12-5, revision December, 2009 per SL-114AW
Although, we have located draft pages for the 60297-12-6 February, 2014 revision that pertain to the magneto timing, we have no record of the draft going forward to the FAA for approval which means that the 60297-12-6 revision technically is not approved for release. We are putting the Magneto-to-engine timing procedure in a new Service Instruction SI-1564
