These provisions for scope expansion of an aircraft maintenance engineer (AME) licence are based on the principle that a person who holds an AME licence, has demonstrated competency to perform maintenance on an aircraft provided they are familiar with the tasks to be performed. The supervised task performance process provides a mechanism by which a licensed aircraft maintenance engineer (LAME) can demonstrate acceptable familiarity with a task that would otherwise be outside the recognised scope of their licence.

What is task supervision?

A LAME may expand the scope of their certification privileges on a task by task basis by satisfactorily performing a task under direct supervision. The supervision can be provided by an accredited trainer or a LAME who is permitted to certify for that particular task.

When is a supervised task performance required?

A supervised task performance is required any time a LAME is performing a maintenance task that is outside the boundaries of their recognised licence scope.

“Recognised licence scope” includes privileges attached to a person’s licence subcategory, any type ratings held by a LAME and any tasks a person has been performing in the normal course of their duties.

What types of tasks require a demonstration of familiarity by a LAME?

If a maintenance task is out of category—for example, not within the scope of a person’s licence—and is not a task that is common to aircraft within the LAMEs licence category, it would be acceptable for supervised task performance.

If a:

  • 2 LAME was to remove and replace a main or tail rotor on a helicopter, they would need to have previously satisfactorily carried out the work under supervision of a person permitted to certify that work. Additionally, in the case of working on a rotor system, they would also be required to hold a credit for CASA basic examination FR (Helicopter controls and systems) or MEA 308 (Remove and install rotary wing rotor and flight control systems and components)
  • B1 LAME were to perform an engine installation on a type rated aircraft for which they do not hold the relevant rating, they would be required to have demonstrated task familiarity under supervision
  • B1 LAME were to remove and replace an aileron on a type rated aircraft, the work would be regarded as a “common” task and would not require task supervision unless an unusual rigging requirement exists
  • B1 LAME proposes to perform a piston engine overhaul, they would be required to have carried out an overhaul of a similar type of piston engine under the supervision of a person who is authorised to certify for the overhaul. “Similar type of engine” would mean one of the following: normally aspirated, supercharged, geared.
  • B1 LAME with a propeller exclusion endorsed on their licence would require a satisfactory task performance under supervision in order to perform minor maintenance such as inspecting, dressing out stone chips and making RPM adjustments to a propeller.

Who can supervise a person performing a task?

To supervise a person’s performance of a task, the supervisor must be familiar with the task. The supervisor could be an appropriately qualified workplace trainer or a LAME or aviation maintenance technician (AMT) who is authorised to perform and certify for the maintenance task being performed under supervision.

How should a LAME record a supervised task?

A LAME should keep a diary to record supervised task performance. Each record should state the date of the task performance, the type and registration of the aircraft if applicable, the maintenance task performed, and the name and ARN of the supervising person. Wherever possible, the supervisor should sign the record as having supervised the task.

Other acceptable evidence would include copies or photographs of maintenance entries certified by the LAME, a written statement by a LAME or a workplace supervisor that the LAME has satisfactorily carried out the task(s).

Would the supervisor be held responsible for future work completed by a LAME who they have task supervised?

As 43.13 (a) places the responsibilities on each person performing maintenance, modification, or preventive maintenance on an aircraft, engine, propeller, or appliance, if the supervisor provided any physical assistance with the task, they would be jointly responsible with the LAME performing the task.

After completion of a supervised maintenance task — under the regulations — the supervisor will not carry any responsibility for future work completed by the LAME (unless they are involved in a further maintenance activity with the LAME).
