SofemaOnline www.sofemaonline.com takes a look at the FAA Training Requirements to comply with AC 120-29A

Initial and Recurrent Maintenance Training

a. Maintenance personnel should be knowledgeable regarding the information contained in this AC and 14 CFR related to any significant aspects of LLM that may pertain to maintenance.

Operator and contract maintenance personnel including mechanics, maintenance controllers, avionics technicians, personnel performing maintenance inspection or quality assurance, or other engineering personnel if applicable, should receive initial and recurrent training as necessary for an effective program.

The training curriculum should include specific aircraft systems and operator policies and procedures applicable to low-visibility operations.

Recurrent training should typically be accomplished at least annually, or when a person has not been involved in the maintenance of the specified aircraft or systems for an extended period (e.g., greater than 6 months). Training may lead to a certification or qualification (e.g., for lower landing minima “LLM”) if the operator so designates such qualification in that operator’s approved program.

b. The training should at least include, as applicable:

(1) An initial and recurrent training program for the appropriate operator and contract personnel. Personnel considered to be included are maintenance personnel, quality and reliability groups, maintenance control, incoming inspection, stores, or equivalent organizations.

Training should include both classrooms and at least some “hands-on” aircraft training for personnel who are assigned aircraft maintenance duties.

Otherwise, training may be performed in a classroom, by computer-based training, in simulators, in an airplane, or any other effective combination of the above consistent with the approved program, and considered acceptable to the FAA.

(2) Subject areas for training should include: Operational concepts, aircraft types and systems affected, aircraft variants and differences where applicable, procedures to be used, manual or technical reference availability and use, processes, tools, or test equipment to be used, quality control, methods for testing and return to service, signoffs required.

Proper Minimum Equipment List (MEL) application, general information about where to get technical assistance as necessary, necessary coordination with other parts of the operator’s organization (e.g., flight operations, dispatch), and any other maintenance program requirements unique to the operator or the aircraft types or variants flown (e.g., human factors considerations, problem reporting).

(3) Procedures for the use of outside vendors or vendor’s parts that ensure compatibility with program requirements and for establishing measures to control and account for parts' overall quality assurance.

(4) Procedures to ensure tracking and control of components that are “swapped” between systems for troubleshooting when systems discrepancies can not be duplicated. These procedures should provide for total system testing and/or removal of aircraft from lower minimum status.

(5) Procedures to assess, track, and control the accomplishment of changes to components or systems pertinent to low visibility operations (e.g., ADs, service bulletins, engineering orders, 14 CFR requirements).

(6) Procedures to record and report lower minimum operation(s) that are discontinued/interrupted because of system(s) malfunction.

(7) Procedures to install, evaluate, control, and test system and component software changes, updates, or periodic updates.

(8) Procedures related to the minimum equipment list (MEL) remarks section to use, which identifies low visibility-related systems and components, specifying limitations, upgrading, and downgrading.

(9) Procedures for identifying and addressing performance assurance for any necessary low visibility-related components and systems, such as for use of “built-in test” features, for required inspection items, and for providing quality assurance, whether performed in-house or by contract vendors.
