Your Top Source for Civil Aviation Products

Keep Your Lines Up is a website owned and operated by ASAP Semiconductor, meaning that we have access to a wealth of aviation products and longstanding market expertise. Since our formation in 2009, we have established ourselves as a strategic distribution partner that provides custom procurement, distribution, logistics, and project management solutions for customers within both the civil and defense aviation spheres. This particular platform specializes in providing civil aviation products for business, regional, and commercial jets, including top-grade engine parts. However, the military-grade part standards we uphold remain the same. In our vast inventory of available items, it is easy to find MS, AS, NAS, and BAC standard parts, as well as those which have otherwise been subjected to rigorous testing and document verification.

Having sourced all of these items from only accredited manufacturers and suppliers, we proudly stand behind the quality of our components. Moreover, we deliver each order alongside its manufacturer trace documentation and any applicable qualifying certifications, so there is never any guess as to the authenticity of our offerings. As you browse our website, we invite you to peruse the various categories at your leisure or search for specific items of interest. Using the provided search tool and filters, it is easy to quickly narrow down our offerings by a specific NSN, part type, part number, and other qualifiers. Kickoff the procurement process with us today to experience how easy your part acquisition could be with Keep Your Lines Up as your sourcing partner!
