Each point (requirement) in Part-26 specifies who is affected by the requirement. Today most of the requirements concern operators of large aeroplanes used in commercial air transport. However, certain requirements can also affect large aeroplanes, and this independently of the type of operation. It is for instance the case for point 26.400 on fire extinguishers, introduced with Commission Implementing Regulation (EU) 2019/133.
Some requirements can also affect Large helicopter.
