For example, an airframe rated AMO may have the capability to perform maintenance or alteration on landing gear, but if the in-house facility cannot accomplish the work scope within a specified time, it may want to contract that work to another facility. It would not be able to contract the work unless the maintenance function of landing gear maintenance was on its DAAO-approved list. 3 Additionally, the AMO may wish to provide a method for which a maintenance function can be added to its DAAO approved function list on an emergency basis. This would be accomplished by explaining how the maintenance function would be added and how the DAAO approval would be obtained in a short period of time.

provide only approval for return to service of a complete type-certificated product following contract maintenance, preventive maintenance or alterations. If the AMO chooses to exercise the privileges of its certificate by issuing an approval for return to service for a maintenance function contracted to the DAAO-certificated AMO, the AMO must determine that the contracted AMO is properly rated to perform the maintenance. An AMO may issue an additional approval for return to service under its privileges, such as tagging a previously maintained or altered article as inspected, provided the AMO:
