  • placing a scalloped lock pin having lugs in axial engagement with the periphery of the rotor disk by installing the pin in a groove which faces outwardly;

    aligning the scalloped pin with slots in the disk to permit insertion of at least two rotor blades in a generally axial direction, each into a corresponding blade attachment slot in the disk;

    inserting said rotor blades in the blade attachment slot such that a groove in each rotor blade is axially and radially aligned with and faces said groove in the disk;

    sliding the scalloped lock pin along the groove in the disk to bring the lugs of the scalloped pin into engagement with the correspondingly aligned grooves in each of the rotor blades; and

    securing the lock pin against circumferential movement.
