Employability Skills | |||
Learning Outcomes and Application | This unit of competency requires application of hand skills, theory knowledge and maintenance publication procedures to repair and overhaul rotary wing dynamic components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.Applications include rotor assemblies and components, transmissions, drive shafts and couplings from piston and turbine engine rotary wing aircraft.The unit is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA). | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Competency should be assessed in the work environment, or simulated work environment, using tools and equipment specified in maintenance documentation. It is also expected that general-purpose tools and test equipment found in most routine situations would be used where appropriate. The application of testing procedures should clearly indicate knowledge of system operation. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed. 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: rotor blades rotor heads, hinge assemblies and swashplates transmission gear boxes, drive shafts and couplings. This must include demonstration of the following repair processes: finishing or re-finishing of metal surfaces through processes, such as polishing, lapping and blending of damage within maintenance manual limits removal of corrosion within maintenance manual limits replacement of seals and gaskets replacement of bearings application of surface treatments, such as alodining restoration of paint finishes. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines). Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors). |
