I would not be surprised to see more information on the subject coming from the FAA. We have been asked by a customer if it was now OK to stop their revision service. I would urge customers to be cautious before dropping a revision service. Revision services are typically cheaper than starting a new subscription so a hasty change could be very expensive. I would also recommend you chat with your local FSDO for the latest feedback on maintenance requirements. Most importantly you should consider the safety of and resale value of an aircraft not maintained to the latest recommendations of the OEM.
