Meeting Boeing D6-51991 Requirements with Kubotek Validation Tool

Developed with input from Boeing to become the trusted name in aerospace data integrity 


Boeing’s D6-51991 requires that Boeing suppliers maintain the integrity of Digital Product Definition (DPD) data through all manufacturing operations.  It also requires its suppliers to “continuously improve the quality of the product delivered.”

An effective way to accomplish not only compliance with Boeing D6-51991, but to greater ensure quality, is to validate changes against a master data file and then clearly communicate those data set changes.  These changes can be a result of CAD data translations, CAD system migrations, and modifications such as revisions or engineering change orders (ECO's).

It’s not just Boeing.  Other aerospace suppliers are adopting this type of data integrity requirement as a way to improve their own design-to-manufacture processes and supply chain quality and accountability.  OEM’s such as Lockheed, Airbus and Gulfstream are also looking to continuously improve by validating digital product data throughout their extended enterprises.


 Validating changes and/or digital product data enhances:

  • CAD model translation assurance,
  • revision control of engineering change orders,
  • long term archiving (LOTAR) and storage requirements, and
  • other quality-based, manufacturing processes

Kubotek Validation Tool is the only geometry-based technology which provides superior accuracy for comparison and validation of CAD part & assembly data.  It is has been deployed to major aerospace OEM’s and to hundreds of aerospace suppliers.

 We invite Boeing and aerospace suppliers to learn more about Kubotek Validation Tool—which includes the PMI/MBD option to help you identify errors to Model Based Definition (MBD) or Product Manufacturing Information (PMI) contained in the 3D model—so you can ensure your data integrity and pass Boeing D6-51991 quality audits.
