Abstract: Means for mounting an engine component to the exterior of an engine's case that is mounted in an aircraft with limited access including a blind mount. The mount includes an elongated bracket fixed to the exterior of the engine case with a clevis at one end of the bracket to receive a blind mount on said engine component. Camming means operatively connected to an accessible torquing member secures the engine component in place. Hook elements on the bracket engage said engine component to allow the operator to free his hands to operate the torquing means. The mount is designed to be compatible with the existing vibratory isolation system built into the engine component.

Abstract: A serrated collar having an inner flange portion adapted to be trapped between the nut and threaded adapter of a Rosan fitting and an outer flange portion having a hole for accommodating a lock or safety wire that is splined to the outer spline of the lock ring for obviating the necessity of locating the lock wire hole directly into the casing.
