CSM ultimate static testing began. A failure occurred at 140 percent of the limit load test which simulated the end of the first-stage Saturn V boost.

The loads were applied at room temperature. Preliminary inspection revealed a core compression failure and upper face sheet separation of the aft bulkhead directly beneath both SM oxidizer tank supports.

A second failure was also observed where the radial beams between the oxidizer and fuel tanks joined the bulkhead and shell. The bulkhead closeouts were peeled for a distance of approximately two inches. No decisions were made regarding repairs, test schedule, etc. These tests were constraints on spacecraft 012.
