George M. Low, MSC, in a letter to Samuel C. Phillips, OMSF, said that the Design Certification Review (DCR) for spacecraft 101 had been completed; that assigned action items had been resolved; and most of the open items had been closed.

Several open issues would be closed at the 101 Flight Readiness Review. Low said: "The MSC subsystem managers have reviewed all the documentation supporting the DCR. I have reviewed the statements of certification by the North American and MSC subsystem managers. I have personally watched the design of Spacecraft 101 develop to a stage of maturity. As a result, I am taking this opportunity to certify that Spacecraft 101 is ready to perform the Apollo 7 mission once the open items are closed."
