Title:Shipping Caps, Covers and Plugs
Issuing Committee:Age-2d Packaging, Handling And Transportability Committee
Scope:This document recommends the definition and utilization requirements for shipping and storage caps, covers, plugs and related shipping hardware. These items are commonly used on aircraft engines and associated hardware but may be used elsewhere.The primary purpose of the shipping closure is to protect the aircraft parts or system from damage and foreign material ingress/egress (e.g., dust, dirt or other contaminants) during transport and storage. Shipping closures are not airworthy items. Therefore, their usage is defined as preventative for the parts to be protected as opposed to operational. Military and commercial customer requirements for the prevention of damage or contamination to stored parts are generally limited to the generic instructions “all openings should be sufficiently covered to prevent the entrance of dust, dirt, moisture or other foreign contaminants”. This recommended practice outlines basic minimum parameters for suggested item construction and usage. Additionally, this recommended practice provides instruction on how to apply these closures to various openings.
