18. รายละเอียดกระบวนการและวิธีการประเมิน (Assessment Description and Procedure)

•    The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

•    Competency should be assessed in the work environment or simulated work environment, using tools and equipment stated in aircraft maintenance manuals. It is also expected that applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.

•    The application of ground testing procedures should clearly indicate knowledge of system operation. Before undertaking any action, system operation knowledge, the relationship of individual components and the links with other systems will be necessary to supplement evidence of ability to troubleshoot the system within the limits of the aircraft/system fault-finding guide. The work plan should consider applicable safety and quality requirements according to the industry and regulatory standards.

•    Functional testing of rotors and rotor control systems with engine/s running may be performed with the applicant directing a pilot qualified on type.

•    A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on at least one (1) item from each of the following groups:

•    Main rotor blades and tail rotor blades.

•    Rotor heads, swash plates and tail rotor pitch control assemblies.

•    Mechanical, powered flight control components.

•    Main rotor, intermediate or tail rotor gearboxes.

•    Drive shafts and couplings.

    This shall be proven via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.
