EASA rules prohibit tech log entry's under the heading FAO because under EASA each tech log entry has to have an appropriate defect removal reply.
Who makes the reply is down to how well your EASA 145 maintenance exposition is written most airlines have a part of the exposition that permits the captain to move a tech log defect from the defects page to the Deferred defect pages provided it is within the aircraft MEL.
It is for your company to negotiate with your maintenance provider to get the approval for the crew to do this, while you are about it you might like the maintenance company to give the crew some "simple & limited task" maintenance approval to carry out and certify minor items of maintenance such as changing lamps, topping up fluids and the like. ( there will be an element of crew training involved)
A lot of maintenance company's are stuck in a bit of a rut and don't like issuing such approvals, this is usualy because they don't know the rules very well themselves and/or the national authorities know even less about the rules and the easiest option of those with little knowlage who you are taking outside their comfort zone is to say it is not allowed.
In my view the EASA prohibition of FIO tech log entry's is a step backward in flight safety as it allowed feed back on things that are not necessarily defects but are of interest of a new crew.
