ABSTRACT:
One of the routines required for maintaining the air worthiness of an aircraft is the frequent inspection of rudder and elevator cables. Given traditional aircraft design, for example the Cessna "335" and "340" aircraft, access to these cables has been achievable only by removing the tail-cone from the body of the aircraft. Composed as they have been of aluminum or ABS plastic, these tail-cones have been prone to breakage. Their replacements, also of ABS plastic, have consisted of two large halves bolted together, one of which must still be removed from the aircraft to allow cable inspection and for which breakage is still a concern. The invented generally one-piece tail-cone molded of fiberglass constitutes a durable replacement for a broken cone. Equipping the new fiberglass cone with relatively small doors to be used for cable inspection allows the tail-cone to remain in place on the aircraft during its conceivable considerably lengthened life span. Coverings for these door holes are easy to remove and reinstall, aerodynamic, safe, and are economical to replace when necessary.
