Baron,Folks,
Schedule 8.
Note that Item (6) make no mention of why a side window might be removed and replaced.
It goes without saying that all maintenance must be carried out to approved data, where something is replaced, various "approved part" rules apply, but one to note here is the provision for parts manufactured in the course of maintenance (Part 21), which is quite different to manufacturing under a production certificate or such as an STC.
It is relatively straightforward to "legally" make side windows, and fit same, I would hope your friendly family LAME would assist. For a non-structural side window, it can be done legally without the expense of an approval from an Approved Design Organization (used to be CAR 35).
Naturally, there is an array of advisory information available that constitutes
acceptable means of compliance.
Either comply with the CAAP/AC or have CASA approve an alternative means of compliance. Believe me, the former is much easier, cheaper and more certain of outcome.
Tootle pip!!
