Notes

CAR-145 organisations, summary notes

Main ideas
  • CAR-145 sets the requirements for a GCAA approved maintenance organisation, with a defined scope of ratings and classes of work stated on the approval certificate.
  • The organisation operates to a Maintenance Organisation Exposition (MOE) accepted by the GCAA, describing its procedures, scope, facilities and management. The MOE must be kept current, and working outside it breaches the approval.
  • Key requirements: suitable controlled facilities including hangars, workshops and secure environmentally-suitable stores; sufficient competent personnel with nominated postholders (an Accountable Manager plus quality and maintenance managers); certifying staff qualified under CAR-66 holding company authorisations; and calibrated, controlled tooling and equipment.
  • Parts and materials must be acceptable, traceable and serviceable with the correct release documentation, and current approved maintenance data (aircraft maintenance manual, service bulletins, airworthiness directives) must be available and actually used.
  • A quality and compliance-monitoring system with independent audits and a corrective-action feedback loop is mandatory, together with a safety management system, occurrence reporting to the GCAA, and retention of maintenance records for the required period.
  • On completing maintenance the organisation issues the certificate of release to service through its authorised certifying staff. Continued approval depends on ongoing compliance verified by GCAA oversight and audit. Smaller non-commercial aircraft may be maintained under CAR-M Subpart F rather than full CAR-145.

Solved examples
  1. What document defines how a CAR-145 organisation works, and who accepts it?

    The Maintenance Organisation Exposition (MOE), which sets out the scope, procedures, facilities and management of the organisation, and is accepted by the GCAA.

  2. Why must a CAR-145 organisation have an independent compliance-monitoring function?

    To audit its own activities against the regulation and the MOE and drive corrective action, demonstrating continued compliance between GCAA audits rather than relying on the regulator to find problems.
