GM1 ML.A.901 Aircraft airworthiness review
CAA ORS9 Decision No. 1
If a CAMO/CAO holding the AR privilege is contracted by the owner, this organisation does not have the obligation to carry out the AR itself. The owner may select another CAMO or CAO to carry out the AR, or request the maintenance organisation to carry it out and issue the ARC in conjunction with the annual inspection.
Please refer to GM1 ML.A.201 to identify the cases where the owner may also request an independent certifying staff (authorised by the CAA) to carry out the AR and issue the ARC in conjunction with the annual inspection.
Point ML.A.901(b) gives a list of the different organisations or persons that are allowed to perform an AR; it does not presume that they have the obligation to accept a request to carry out an AR.
