(1) It is thought that people which perform the zonal tasks have an adequate knowledge of the aircraft construction and systems installations thus a list of all the items contained in the zones to be inspected is not given.

(2) If you find damage, corrosion, leaks, it is recommended to refer to the related structure/system inspection ata-chapter for detailed inspection and corrective action

(3) Any Fairing, access panel, access door, etc removed or opened to gain access to zones should also be examined during the zonal inspection. This requirement is not specially quoted within each individual procedure because it is a standard maintenance practice.
