Posted By lawrence baldwin Chris My experience is with helicopters, not light aircraft, but in the past we did have youngsters on work placements, before you are able to carry out a RA, you need to get a comprehensive list of activities the youngster could be expected to be involved in, bearing in mind any maintenance that requires a tech log entry can only be done by a licenced engineer. I would thinik for the most part he/she would only be a witness but may get involved in refueling, defueling (aviation gasoline is as flammable as 4 star with additional controls of earthing required by CAA), aircraft movements (manual pushing) tyre inflation, oil replenishment and any equipment used for any of the above tasks. This list though is not meant to be difinitive but just a quick summary off the top of my head. He would need a comprehensive induction on the do's and dont's particularly relating to the danger areas of aircraft, in this instance the propellor and how to approach aircraft with the engine running, also any other aircraft operating in the vicinity that may have differing risks, and other risks such as noise and fire and emergency controls that are requirements of and would be expected at the aerodrome. PPE required as a minimum would be ear protection foot protection and coveralls if involved in daily maintenance and aircraft movements. But first liaise with the placement and get a full picture of activities and expected levels of supervision and control particularly in the higher risk activities, then plan your risk control strategy.
