AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect each internal and external snap fastener to determine whether they unbutton by hand. For external snap fasteners that do not unbutton by hand, replace the male part of the snap fastener and install self-gripping tape if it still does not unbutton by hand. Thereafter, inspect the external extraction tape and self-gripping tape and replace any tape that is cracked, torn, disintegrated, worn, or missing, and replace the snap fasteners. For internal snap fasteners that do not unbutton by hand, install self-gripping tape and replace the snap fasteners.
