  • Patent number: 10967989
    Abstract: A tail-cone reinforcement angle of a Cessna 180-185 series aircraft is repaired by the removal of an aft most section of that tail-cone reinforcement angle and its replacement with an elongated splice body. The elongated splice body is attached to the remainder of the tail-cone reinforcement angle and to the tail-cone portion of the fuselage of the aircraft. The aft section of the original tail-cone reinforcement angle is subject to the development and propagation of cracks in the area of the rear pivot shaft receiving bore, which cracks render the aircraft unfit for use. The invention includes the provision of a suitable elongated splice body, a method for its installation, and a tool kit which is usable in accomplishing the removal and replacement of the aft section of the tail-cone reinforcement angle.
