The test plan was revised to delete the temperature-shock, temperature and humidity, and altitude tests from the Phase I testing and an edge drop test was added. After drop testing was completed, the end caps were removed and the potting in the ends of the energy absorption cylinder was cut out. Two additional flat drop tests from 36 inches were then performed, the first at a position of 90 degrees from the positions originally tested and the second at 180 degrees from the first. For the second test, the outer skin was removed. The first test resulted in a peak deceleration of 61.5gs and an average deceleration of 45gs. The second test, with both potting and skin removed, resulted in a peak deceleration of 41gs.
