Structural Monitoring Systems Plc announced that it has received notification from Delta Engineering that it has submitted the completed probability-of-detection (POD) testing data to the Federal Aviation Administration (FAA) as specified in the Issue Paper (IP) for the GoGo 737-800 2ku WiFi program. The POD test report was submitted to the FAA's New York Aircraft Certification Office (NYACO). The independent testing process, which began in December 2020, was completed by the Company's industry partners - Delta Engineering and Sandia National Laboratories. Delta Engineering will also submit to the FAA a final Compliance Report over the next week or so which defines how SMS met and exceeded expectations for the initial IP guidance requirements to achieve certification. FAA feedback is expected prior to the end of second quarter of 2021 for review of the test data and to return any follow up questions. CVMTM is progressing to a commercial and technical ready status which will allow the industry to replace costly ground based hangar inspections.
