Employability Skills | |||
Learning Outcomes and Application | This unit of competency requires application of procedures and techniques associated with the inspection and maintenance of aircraft structures, and with the performance of a limited range of metal and composite repairs during scheduled or unscheduled maintenance, including special inspections required after events, such as heavy landings, overstress or flight through heavy turbulence. Applications include the individual or team-related performance of structural maintenance activities on fixed or rotary wing aircraft on the flight line or in the hangar.The unit is part of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathway. The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide. | ||
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 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 across the variables in the Range of Conditions as follows: inspection and/or testing of at least one (1) item from each of: non-ferrous and ferrous alloys and composite (FRP) materials used in aircraft construction structural fastening and attachment hardware and/or devices seals and sealants glass and moulded plastics application of NDT techniques doors, hinges and locking mechanisms for damage/misalignment inspections applicable to each of safe life, damage tolerant and fail safe structure relevant to enterprise ageing aircraft inspection programs recognition of each type of damage: impact damage fatigue cracking corrosion delamination of composites and bonded structures one (1) repair task from each of the following groups: remove corrosion by chemical and mechanical methods restore protective coatings apply sealants and jointing compounds freehand precision hole generation remove and install structural hardware and fastening devices remove and replace bushes, bearings and bearing surfaces metal scab patch, flush, splice, lap and formed section repair composite external patch, scarf and stepped repairs. This shall be established via the records in the Log of Industrial Experience and Achievement or, where applicable, 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). Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards. Individuals being assessed who have already attained MEA369 Inspect and maintain structures and related components of non-pressurised small aircraft, MEA370 Repair the structure of non-pressurised small aircraft and MEA371 Perform major repairs and modifications to small aircraft metal structure will have met the requirements of the Performance Criteria and Range of Conditions variables for Elements 1 to 3 for common variables. Those who have attained MEA410 Maintain aircraft structure/components will have met the Performance Criteria and Range of Conditions variables requirements for Element 1. The Log of Industrial Experience and Achievement records relating to the units listed above may be accepted as also meeting the evidence requirements for this unit in the applicable areas. |
