Bringing a redesigned cabin-pressure system to certification — within the constraints of a B737 MAX programme schedule
Project details
Customer: Nord-Micro GmbH & Co. KG
Branch: Aviation
Period: 09/2017 – 05/2020
The challenge
My customer redeveloped the cabin pressure control system for the commercial aircraft B737 MAX.
Certification depended on one critical question: which verification evidence from the existing B737 platform remained valid for the redesigned system, and which evidence had to be generated again? The programme schedule did not allow for full re-verification.
Cooperation
Over the course of a few months, I reviewed more than 2,500 requirements and assessed the applicability of existing B737 verification evidence to the redesigned system.
The result was a clear and solid verification scope that distinguished, requirement by requirement, between evidence that remained valid and evidence that had to be recreated.
What we have achieved
Project results
Project goal achieved
More than 2,500 complex requirements and their verification evidence had been evaluated within a few months, and my customer had a complete overview of the compliance status of the system and its components.
Clear structure
At the end of the assignment, all Lessons Learned from the project and the project results were clearly communicated to the involved employees, so that they can also benefit from them in future projects.
Confidence for implementation
After the collaboration, my customer had clarity on which verification documents were still valid for the revised system. With that, they knew what to do in order to deliver the revised system on time.
