Inspection Poetponed!!

I have been informed by the VSC-24 Owners Group that they want to postpone the inspection l by 2 weeks - to the week of March 16,1998. The reason for the delay is an unsuccessful paint 1 job on the mock-up - the topcoat peeled in several areas.

For Mike A., Steve D., Ed H., Debbio J., and Mike V., regarding other subjects discussed I with the Owners Group:

1) They will tabulate data for UT scans on the painted surfaces for the UT tranadocers that they plan to use per the final procedure.

2) We need to get together and discuss the subject of grinding the entire weld crown off of the mockup. The Owners Group wants to seriously pursue this option as a part of their development process. There is the possibility that this examination approach may involve less dose, and yield better examination results then the current ' side view" method. However, that call cannot be made without trying out this approach.

From the regulatory and inspection logistics perspective, there ars concems, it is my understanding that the UT response for the weld with a crown will differ from the reshaped weld.

If the Ownars Group proposes the use both examination methods (a decision that remains to be made by the Owners Group), then what do we need to inspect? la there "before" and 'atter" data for the " side view" exam that we can review, or do we need to directly observe both examination methods. If we need to directly observe both methods, we need a basis. I would like to set up a call for tomorrow 2/24/98 at 11:00 am EST to' discuss this issue and come up with an answer for the Owners Group. Please let me know if this time is acceptable / unacceptable. I v411 try to call you later today.

Thanks Allen CC: FCS, TJK1, MGR, EJL, PLE 9
