Category A Licence Privileges Explained
In aircraft maintenance, holding an Aircraft Maintenance Engineer (AME) licence does not automatically mean that a person can certify every maintenance task.
A Category A licence holder has limited certification privileges, mainly covering minor scheduled line maintenance and simple defect rectification.
Let's understand the privileges, limitations and responsibilities of a Category A licence holder.
1. What are Category A Privileges?
A Category A licence holder is permitted to issue a Certificate of Release to Service (CRS) following:
Minor scheduled line maintenance.
Simple defect rectification.
However, these privileges are subject to specific conditions established under the applicable licensing requirements and the approved maintenance organisation's authorisation.
2. Four Essential Conditions
Condition 1 – Privilege: The work must fall within minor scheduled line maintenance or simple defect rectification.
Condition 2 – Performance: The maintenance task must be within the permitted scope of Category A privileges.
Condition 3 – Permission: The specific task must be included in the authorisation issued by the approved maintenance organisation (AMO).
Condition 4 – Personally Performed: The licence holder must have personally performed the maintenance work before issuing the CRS under these privileges.
3. Why is AMO Authorisation Important?
An AME licence and an AMO authorisation are not the same thing.
AME Licence: Establishes the individual's licensing privileges.
AMO Authorisation: Defines the specific tasks the organisation permits that individual to certify.
Therefore, a Category A licence holder cannot certify a task simply because it appears to be a minor maintenance activity. It must also be specifically endorsed in their authorisation.
4. Practical Aircraft Maintenance Example
Imagine Rahul, a Category A licence holder, working on an aircraft during line maintenance.
He performs an authorised simple defect rectification task.
Before issuing the CRS, he must confirm:
Is the task within Category A privileges?
Is the task specifically included in my AMO authorisation?
Have I personally performed the task?
Have I completed the required maintenance procedures and documentation?
Only when the applicable requirements are satisfied can he exercise the relevant certification privilege.
5. Remember the 4P Rule
P1 – Privilege: Minor scheduled line maintenance.
P2 – Performance: Simple defect rectification.
P3 – Permission: Specifically endorsed in AMO authorisation.
P4 – Personally: Work personally performed.

7. Final Message for AME Students
Remember that an AME licence is not unlimited certification authority.
A responsible aircraft maintenance professional must understand the limits of their licence, follow the organisation's authorisation and complete the required maintenance procedures.
Golden Rule:
Right Task + Right Authorisation + Personal Performance = Safe Maintenance.
Instructor's Message: Never certify what you have not personally performed or what is outside your authorisation. In aviation maintenance, safety and accountability always come first.
