Can an airworthiness review certificate (ARC)/recommendation be issued after an airworthiness review with open findings?
Neither an ARC nor a recommendation can be issued with open findings. Each finding requires a corrective action before the issue of the ARC or recommendation. The corrective action should be adequate to the open finding and it should be carried out and verified by the airworthiness review staff (ARS) before the issue of the ARC/ recommendation.
