Line maintenance

Any work at outstations of an air carrier must be performed by approved maintenance organisations. A carrier is encouraged to apply for outstation line maintenance approval based on management by its main base. Equally, the maintenance organisation of a carrier is regarded as an independent organisation when it performs this work on aircraft that are not its own. 
General servicing work is not regarded as line maintenance. Self-handling or entrusting to another company by agreement, the carrier submits application to its local civil aviation management organisation for line maintenance approval at outstations for specific aircraft under its maintenance agreement. 
          A maintenance organisation takes full responsibility for compliance between maintenance at outstations and 145 requirements to the approved standards. Airworthiness documentation provided by the aircraft manufacturer must be available onsite at outstations.
Line Maintenance agreements
If a carrier's maintenance organisation entrusts other companies to perform such work or release at an outstation, it has to sign a clear maintenance agreement with the contracted company. The maintenance agreement must include the following: 
(1)Technical documentation, material, management procedures provided by the carrier 
(2)Training instructions provided by the carrier; 
(3)Work scope entrusted by the carrier and authorization instructions; 
(4)Maintenance records and reporting methods.

A copy of all these must be kept at the outstation. A line maintenance organisation has full responsibility for compliance to 145 requirements and never performs work at locations out of maintenance certificate approval.
Organisations must have the tools & equipment necessary to perform work at locations listed in maintenance certificates, and special equipment belonging to the carrier by means of agreements.
