145.A.75 defines the privileges granted to an approved Part 145 organisation, including the right to maintain aircraft and components within its approved scope, issue certificates of release to service, and, where specifically approved, perform maintenance at locations other than those listed in the approval.
What it means in practice
An approved Part 145 organisation has the privilege to carry out maintenance on any aircraft or component within the scope of its approval and to issue the corresponding certificate of release to service. This is the core commercial and operational value of the approval. Without it, the organisation cannot legally release maintenance work.
The privileges also extend to performing maintenance at line stations that are controlled by the organisation, and in certain circumstances, carrying out maintenance at locations not specified in the approval, for example when an aircraft is grounded at a location where the organisation does not have a permanent presence, provided the MOE contains the appropriate procedures.
Key requirements
The organisation may only exercise its privileges while it remains in compliance with Part 145. The privilege to perform maintenance is directly linked to the scope of work stated on the approval certificate. The privilege to issue a CRS may only be exercised by certifying staff authorised in accordance with 145.A.35. The organisation must ensure that all maintenance performed under its privileges meets the same standards regardless of where the work is physically carried out.
Where maintenance or specialised services are subcontracted, the subcontracted activity must remain under the organisation's management system in accordance with 145.A.205 — and the privileges do not extend to subcontracting a base maintenance check of an aircraft or a complete engine or engine-module overhaul to an organisation that is not itself appropriately approved. Since the deletion of the former 145.A.80, the limitations on the organisation are expressed through 145.A.75 and the terms of approval rather than through a separate limitations clause.
For light aircraft managed under Annex Vb (Part-ML), an organisation that is specifically approved for it may also perform the airworthiness review and issue the corresponding airworthiness review certificate (ARC), in accordance with ML.A.903 and the privileges listed in 145.A.75(f).
Common compliance gaps
Organisations sometimes inadvertently exceed their privileges by performing work on aircraft variants or component types not covered by their specific ratings. This is particularly common at line stations where the full range of fleet types may arrive but the station's approval may not cover all variants. Exercising privileges at non-approved locations without proper procedures in the MOE is another area of non-compliance.
