UPON FURTHER INVESTIGATION IT WAS NOTED THAT THE RT (A) SYSTEM MODULE CHECK VALVE INSTALLATION CAP HAD SHEARED IN THE MODULE CHECK VALVE INSTALLATION CAP HAD SHEARED IN THE MODULE PACKAGE, ALLOWING A LARGE QUANTITY OF HYDRAULIC FLUID TO BE LOST.  DO NOT HAVE A PROBABLE CAUSE OR ANY RECOMMENDATIONS.  (K)
