Is it true that a category "C" MEL must be repaired within 10 days of discrepancy recording?

A category "C" Minimum Equipment List (MEL) item is one that allows the aircraft to remain airworthy with certain limitations in place. The important aspect of a category "C" item is that it does not necessitate immediate repair; instead, it specifies that the aircraft may be operated with the inoperative equipment for a longer period, which is generally up to 10 days, provided that specific conditions and operational limitations are met.

The phrasing of the question might lead one to think that a fixed timeframe for repair is mandatory for all cases, which is not accurate for category "C" items. As they allow the airplane to continue safe operations with inoperative equipment, this flexibility is a key distinction that sets category "C" apart from categories that may impose stricter repair timelines. Therefore, asserting that it must be repaired within 10 days misconstrues the applicable operational guidelines for category "C" MEL items.

This deeper understanding of MEL categories reinforces why the assertion that a category "C" MEL must be repaired within 10 days is false.
