Required Skills
|
Required skills |
Look for evidence that confirms skills in: Application of relevant occupational health and safety (OHS) practices The use relevant maintenance documentation and aircraft manuals to: remove flight control surfaces check the mass balance of control surfaces where required install flight control surfaces remove power flight control system components install power flight control system components remove mechanical flight control system components install mechanical flight control system components |
Required knowledge |
Look for evidence that confirms knowledge of: Flight control surface and system component attachment methods Connection hardware and couplings Electrical circuit isolation and plug removal and installation Requirements for balancing of control surfaces Flight control system rigging requirements Requirements for independent inspection of work performed on flight control systems and components Relevant OHS practices Relevant maintenance manuals Relevant regulatory requirements and standard procedures |
Evidence Required
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to apply hand skills and use maintenance publications to remove and install fixed wing aircraft flight control system components while applying all relevant safety precautions. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The underlying skills inherent in this unit should be transferable into other units that require similar techniques. It is essential that safety precautions applicable to the fixed wing flight control system being maintained are fully observed, understood and complied with (especially flight control system inter-relationships with other systems where applicable). An awareness of dual inspection requirements associated with work on flight controls and systems must also be demonstrated. Evidence of transferability of skills and knowledge related to removal and installation is essential. This may be demonstrated through removal and installation of a representative range of the fixed wing flight control system components listed in the Range Statement. An understanding of component attachment methods and the need for adjustment or rigging and system operation as it relates to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on at least one item from each of Groups 1 to 3 listed in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry . |
Context of and specific resources for assessment | Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate. |
