Aviation Maintenance Organizations Regulations

An approved maintenance organization (AMO) must re-apply for initial issuance if they don't renew their approval within the specified timeframe.

An AMO's approval remains valid unless it's surrendered, superseded, suspended, revoked, or expired. This depends on continuing to comply with regulations, allowing inspections, and paying required fees.

The Authority can inspect an AMO to assess if it meets the regulations at any time.

The Authority may conduct inspections at least once a year to check an AMO's compliance.

The Authority can suspend or revoke an AMO's certificate if it's found they don't or no longer meet the regulations.

An AMO must develop and update its training program based on the specific tasks and responsibilities of its operation.

An AMO must ensure every employee assigned to maintenance, inspections, or modifications can perform their assigned tasks.

An AMO must revise its training program and submit it to the Authority for approval.

An AMO must keep detailed records of individual employee training for at least two years.

An AMO's training program includes initial, recurrent, specialized, and remedial training to ensure employees maintain their skills.

AMO's quality system must include a plan to check if maintenance procedures are following the approved standards.

The quality assurance program must include procedures to monitor compliance with required aircraft and aircraft component standards.

AMO's quality system must include a procedure to initially qualify and periodically audit persons performing work on behalf of the AMO.

The quality system needs a feedback loop to report any issues found during audits to the responsible managers.

AMO's quality system should review all maintenance procedures annually.

AMO's quality system should track audit schedules, completion dates, and keep records accessible to the authority.

Audit reports that find non-compliance or poor standards must be communicated to the Accountable Manager.

Small AMOs can contract the independent audit portion of their quality system to another approved organization or a qualified individual.

An AMO must keep training records for at least two years.

A person working on aircraft maintenance must have at least 8 hours of rest before starting their shift.

A person cannot be scheduled to work more than 12 consecutive hours on aircraft maintenance.

In emergencies, maintenance workers can work up to 16 consecutive hours, or 20 hours in a 24-hour period.

After an unscheduled duty period, maintenance workers must have a mandatory 10-hour rest period.

An AMO must have a roster of all management, supervisory, inspection, and certifying staff, detailing their responsibilities.

Each certifying staff member must receive written notification of their specific responsibilities.

The scope of the authorization document must be clearly defined, with an interpretation document available if codes are used.

An AMO can outsource some maintenance and alteration work, but they must ensure that any contracted work meets all the requirements and is done according to approved methods.

An AMO can only work on aircraft they're approved for, and only if they have all the necessary resources, including facilities, equipment, and certified staff.

AMOs can't contract out the complete maintenance or alteration of a type-certificated aircraft. This is a core function they must perform in-house.

An AMO can't approve return to service without verifying that the work performed was satisfactory, even when the work was contracted out.

An AMO must certify that the aircraft or part is ready for service, ensuring that all required maintenance has been performed correctly according to their manual.

The release to service certification must clearly state that the work was done according to regulations and that the aircraft or component is ready for service.

The release to service certification must reference the manufacturer's maintenance instructions or instructions for continued airworthiness.

When an aircraft or component has been disassembled, cleaned, inspected, repaired, reassembled and tested using approved methods and standards.

The process of taking an aircraft or component apart, cleaning it, inspecting it, making necessary repairs, and putting it back together.

The process of verifying that an overhauled aircraft or component meets the required standards and is safe for use.

An aircraft or component that has been disassembled, cleaned, inspected, repaired, and put back together to the same quality as a new one.

The process of verifying that a rebuilt aircraft or component meets the required standards and is safe for use.

Required documentation must be completed for any aircraft or aeronautical product that has undergone maintenance, preventive maintenance, rebuilding, or alteration.

If any maintenance or alteration changes the operating limitations or flight data of an aircraft, these changes must be documented in the approved aircraft flight manual.

The Authority may prescribe specific procedures for how a maintenance or alteration entry is recorded and approved.
