Johnie Quest at AirWolf falsely claimed to have the STC as required for our TBM Avenger flying on Limited airworthiness cert. Anybody help with paperwork - either 337, or ??? Must be at least ONE B-25 out there with this expensive, but now useless, filter.
The FAA around here will no longer issue a Field Approval on Oil Filters. It has to be done according to an STC process. It can be done as a one off STC applicable to that N Number only.
That sends it through a different approval process that an inspector at the FSDO would use.
