Regulations and Exemptions

Q7.  What are the requirements to be followed by an air operator that is not the holder of an Approved Maintenance Organization (AMO) Certificate?

Because the certificates are independent, there is no difference in principle between the responsibilities of operators with an AMO and those without. In all cases, the Air Operator is responsible for keeping the aircraft technical records, planning the scheduled maintenance, deciding what other maintenance needs to be done, and removing from service any aircraft that does not comply with the applicable airworthiness requirements. AMOs are responsible for correctly performing and certifying the requested work. In practice, operators without an in-house maintenance capability (and those with such a capability who choose to contract out certain kinds of maintenance) will require more detailed records of communications with their maintenance providers, whereas those who have all their maintenance performed in-house may be able to rely to a greater degree on previously established procedures that outline the responsibilities of the respective operations.
