28.07 If the MMEL does not specify rectification intervals
        If the MMEL for an aircraft type does not specify a rectification interval for an inoperative item, the rectification interval for the item in an MEL for an aircraft of the type must clearly reflect the significance of the item for the safe operation of the aircraft.

28.08 Effects of repairs or modifications made to the aircraft
        If:
(a) a repair or modification is made to an aircraft; and
(b) the approval for the repair or modification places a new condition or limitation on the operation of the aircraft for flight with an inoperative item;
        then the conditions or limitations specified in the MEL for the inoperative item must be at least as restrictive as the conditions or limitations specified in the approval for the repair or modification.

28.09 Extension of rectification interval
       (1) A rectification interval prescribed by this Chapter is prescribed for the purposes of paragraph 91.945 (5) (b) as an original rectification interval.
       (2) For paragraph 91.945 (5) (g), this section prescribes the period by which an extendable original rectification interval may be extended.
Note   Category B and Category C rectification intervals are the extendable rectification intervals.
       (3) An original Category B rectification interval may be extended up to a maximum of 3 days.
       (4) An original Category C rectification interval may be extended up to a maximum of 10 days.
       (5) A reference in this section to an original rectification interval (however expressed) is a reference to the relevant rectification interval before any extension of it under this section.
Note   The intended effect of subsection 28.09 (5) is that a rectification interval that has been extended once may not be further extended.
