Aircraft Flight Operation Regulations Article 316

No person may operate any aircraft that has undergone maintenance unless:1. It has been approved for return to service by a person authorized;2. The maintenance record entry required has been made according to “Regulations of Airworthiness and Maintenance Management for Aviation Products, Appliances and Parts”.No person may carry any person (other than crew members) in an aircraft that has been maintained, rebuilt, or altered in a manner that may have appreciably changed its flight characteristics or substantially affected its operation in flight until an appropriately rated pilot flies the aircraft, makes an operational check of the maintenance performed or alteration made, and logs the flight in the aircraft records.The aircraft does not have to be flown as required in the preceding paragraph herein if, prior to flight, ground tests, inspection, or both show conclusively that the maintenance, preventive maintenance, rebuilding, or alteration has not appreciably changed the flight characteristics or substantially affected the flight operation of the aircraft.For aircraft engaged in non-revenue flight operation, the requirement of a maintenance release shall not be waived unless the request for waiver and pertinent procedures for such operation has been approved by CAA. Thereafter, with no malfunction occurrence to the aircraft and no maintenance actions taken, for the flight crew who have completed the approved training, the requirement of a maintenance release may be waived after the flight crew has conducted a before flight check and recorded the completion of the check in the maintenance log book.
