Marking Blocks: A Review of Notable Features and NSN Identification Methods

From the structural bodies of aircraft to a range of individual hardware items and fasteners, permanent marking blocks are a common design element in the aviation industry for the means of conveying important data for traceability and compliance. With marking blocks sometimes being independently purchasable items that must be carefully chosen based on their intended assembly or part, having accuracy in identifying suitable options for procurement is a must. This is where the National Stock Number (NSN) system comes into play, offering a standardized means for buyers and other professionals to engage in supply management with ease.

As Integrated Aviation Electronics specializes in connecting customers with options for marking blocks and other aircraft solutions with curated catalogs based on NSN data, having an understanding of such part types and the benefits derived from standardized identifiers can be useful for buyers seeking to streamline fulfillment. This blog will serve to offer such an introduction, so be sure to read on to gain useful insight for addressing marking block part needs and beyond.

What Are Marker Blocks In the Context of Aviation?

As stated before, marker blocks serve to convey important data or information to a viewer, such as part numbers, serial numbers, manufacturer information, regulatory data, date of manufacturing, and beyond. While the various forms of documentation that commonly accompany any purchase are essential for a range of basic review and compliance needs, marking blocks guarantee a permanent and physical record that can be referenced by technicians for a range of traceability goals. In order for the important data on blocks to remain legible in the face of long-term exposure to operational and environmental stressors, these components generally come in the form of:

Data Plates & Tags: For larger assemblies like engines, wings, flaps, and beyond, data plates and tags made from stainless steel or other metals are most common. To ensure security, these marker blocks are either riveted onto workpieces or attached through another, more permanent means.
Placards & Decals: Within interior cabin spaces and exterior servicing areas, placards and decals prove to be prevalent with their role in conveying instructions for servicing tasks, information for emergency procedures, etc.

With a variety of marker block options at the disposal of a buyer and the lack of clarity offered by many conventional identifiers, leveraging NSN data becomes a key strategy in confidently narrowing down the perfect option for any requirement.

The Benefits of Shopping for Marker Blocks by NSN

While one may begin the search for fulfillment options with a manufacturer part number or product description, such identifiers are not always the best for streamlining processes and guaranteeing a match. For example, part numbers are not standardized between manufacturers, meaning that two entities may use the same exact identifier for completely different items. On the other hand, marker block descriptions may vary widely between documentation and lists, with online catalogs often presenting these items as “Block Marking NSN parts” for alphabetized part type organization. As such, the use of NSN data becomes increasingly useful for its ability to remove any confusion or risks surrounding discrepancies in presentation.

Major Benefits of Using NSN Data for Searches

Standardized Identifiers: Every NSN comes in the form of a 13-digit code that is uniquely assigned to items based on shared design characteristics or function, providing a means for everyone from government agencies and manufacturers to NATO ally nations to trade and manage material items of supply with shared language. For buyers of marker blocks, this translates into full confidence in purchasing decisions as exact needs are narrowed down quickly.
Manufacturer Identification Codes: NSN data is regularly tied to a range of listing information, such as Commercial and Government Entity (CAGE) Codes. When searching for items by NSN, one can cross-reference this data with manufacturer part numbers and CAGE Code information to have clarity into the source of any desired item.
Lot and Batch References: Lot numbers identify the specific production run of a component, with such information regularly being provided on marker block parts and/or connected to associated NSN data.

Tips for Searching and Securing Marking Blocks Online

As buyers prepare to search the market for suitable marking block fulfillment options, it is important that they have the basics down for common lookup and vetting practices that mitigate risk and facilitate confidence in decisions. Generally speaking, measures that allow for these goals to be realized include:

Identifying Associated NSNs: If starting with part numbers as a reference, be sure to use government databases, manufacturer documentation, and the NSN lookup tools on Integrated Electronic Parts to cross-reference information and confirm the NSNs of any desired items.
Search Catalogs by NSN: As we have mentioned before, NSNs provide a sure way to narrow down exact items of need without any worry for issues that stem from overlapping part numbers or differences in descriptions. As such, utilizing purchasing platforms that allow customers to look up needs by NSNs can streamline fulfillment and ensure exact parts are purchased, whether projects call for marking blocks, towbar assembly NSN parts, or other such items.
Vet Potential Sources: Even if you have the ability to locate specific needs with ease, having assurance that the distributor or supplier you purchase from is going to address requirements with care and efficiency is essential. Typically, it is recommended that customers looking for aviation-oriented marking block parts prioritize sources with AS9120B, ISO 9001:2015, and FAA AC 00-56B accreditation, as this attests to industry-leading inventory management and quality control practices.
