MALFUNCTION INVESTIGATION OF SIMULATOR, BOOBYTRAP, FLASH: M117 SIMULATOR, BOOBYTRAP, ILLUMINATION; M118 AND SIMULATOR, WHISTLING: M119
Abstract
A malfunction investigation was conducted on Boobytrap Simulator M118. The investigation disclosed a greater force on the pull cord was needed. This was done by the use of a spring with increased tensile strength and through a change in procedures for setting up the simulator to obtain full energy from the spring action. Various tests were made with the old and new spring and procedures. The investigation also showed that certain test procedures were impractical and unrealistic in that they permit the acceptance of certain simulators, which do not meet requirements for use in the field. It was concluded that improved performance will be obtained from these Boobytrap simulators through the use of the improved spring and the new procedures in setting up the simulators. Drawings and published procedures will be revised accordingly. By retesting under the new procedures and using the improved spring, it will be possible to remove from suspension lots that have been placed in Grade III (unserviceable) because of pull cord failure.
