Requires replacement of certain passenger windows with Macaer-manufactured jettisoning systems. Prompted by the discovery during a maintenance operation that several self-locking nuts of a window jettisoning system could be loosened by hand. The function of these nuts is to hold the threaded axis and associated cable tight, as part of passenger windows’ jettisoning system mechanism. Relevant investigations determined that certain cable kits, part of the windows jettisoning system, might not be in conformance with applicable specifications.
