CAA ORS9 Decision No. 1
(a) The tools ‘necessary for day-to-day maintenance’ refers to those needed to perform standard maintenance practices plus those needed in order to complete the normal servicing tasks as well as those needed up to the annual/100-hour or equivalent inspections and which are common to the majority of aircraft contained in the scope of approval.
(b) The availability of tools rarely used because the particular maintenance task is very rarely performed can be handled through a procedure in accordance with CAO.A.050(a)(2).
