An early function of the FMU-98 fuze mounted on the 2.75-in. rocket occurred approximately 0.1 sec after mechanical arming. Circumstantial evidence is documented that indicates the 600-G, Skinny inertial switch to be the cause. The theory is that the switch had a deformed gap and was excited into closure by rattling of the rocket fins and sputtering of the rocket motor. Although the evidence is not conclusive on the cause of the early function, a precautionary change to the less resonant, 600-G, low cost switch is recommended. (Author)
