Analysis

Due to low oil pressure and high oil temp the right eng was secured. During the precautionary landing gear extension was delayed until aprx 800 ft AGL. Since the right eng powers the only hydraulic pump a landing gear down and locked condition was not possible by the normal means. As the gear were extended and hydraulic pressure began to decrease the plt realized that normal gear extension would not occur. The alt of the acft precluded the emerg extention of the landing gear. Shortly after touchdown the right main landing gear collapsed.
