You may assemble the airframe/engine but you will need someone with an IA to sign off the paperwork and inspection. You can sign for any N reg as long as you have accomplished the task previously either with another mechanic or under supervison. This is important as you are not authorised to work on a type or complete a task that you have no RECENT experience on. People in this thread are giving you good advise. If you want to avoid a LOI or worse a little bit of research would do you no harm!!!
