Description of Driving Event:
During the post modification pressure test, the fore and aft cavity walls deflected inward until it reached the full pressure (8.0 psi) deflection value at only 2psi. The test was stopped because of the large deflections present at only 2psi. An investigation was performed to determine the cause of the large deflection at 2psi. It was determined that the contractor had underestimated the cavity wall stiffness by a factor of 4.
