CVMTM Smart Sensor Solutions
"As reported during the half-year, the AEM team continues to positively progress the certification of the Company’s CVM™
Smart Sensors for the Aft Pressure Bulkhead (APB) inspection – Boeing Service Bulletin 737-53A1248.
As reported in the September 2023 quarterly update, there were three remaining specific technical issues in relation to
the certification of the CVMTM sensors, with AEM now having successfully satisfied two of those three technical issues as
identified by Boeing’s certification engineers.
The additional round of POD testing was successfully completed during the half-year for both the CIC coating testing applied
to the sensors on installation, as well as their performance ability during extremely hot and cold conditions.
Once again, at no stage during any of the testing – including in the additional testing required by Boeing– have the sensors
failed to perform as expected and required.
As outlined in the December 2023 quarterly, the remaining issue ahead of certification involves testing of the sensors’
performance at the lowest equivalent load as seen on the 737 APB and the ability for the CVM™ sensors to detect cracks that
have formed under that low stress level.
The AEM team, led by Trevor Lynch-Staunton, Chief Technical Officer at AEM, has developed and presented a number of
proposals to the Boeing Certification Engineers and Management with the intent of agreeing a course of action to satisfy this
final requirement with Boeing as a matter of urgency.
As previously stated, Boeing and the Company continue to work through the remaining issue and an agreed upon plan
providing the technical and substantiation data required to show compliance with the applicable requirements.
As stated previously, further updating to the Boeing project timeline released by the Company in early December will be
released to the market as soon as confirmation has been received."

The timeline was released in early December, this is now 4 months later. Why has confirmation for an updated Boeing timeline not been confirmed? Is there no follow up?

"Delta Air Lines continues the agreed installation of the CVMTM APB kits on its 737 fleet ahead of certification release with
new installation training for an MRO facility in Kansas City becoming the fifth MRO trained for Delta Air Lines."

Where is the news about Delta installations? Have they made additional installations this calendar year & if so where is the report, advising shareholders?
If there have been no further installations, why not?
