Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

MEA392 - Disassemble aircraft piston engines

What evidence can you provide to prove your understanding of each of the following citeria?

Determine requirements

  1. Engine defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
  2. Piston engine is inspected in accordance with maintenance publications to establish serviceability state and confirm defects, if necessary
  3. Piston engine build status is determined and quick engine change (QEC) components are recorded in accordance with standard enterprise procedures
  4. Modification status and engine operating hours are clearly established from the engine log book to assist in determining the repair or overhaul requirements for the engine
  5. Extent of overhaul or repair is identified and documented in accordance with standard enterprise procedures
Engine defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
