COMPLIANCE: Required as indicated unless already accomplished.

To assure continued structural integrity of certain screws in the airplane control system, in accordance with instructions set forth herein and in Beechcraft Service Instructions No. 0629- 150, Revision II or later approved revisions, accomplish the following:

A) Within 100 hours time-in-service after the effective date of this AD:

For affected models and serial numbers, determine those Item Numbers applicable thereto by referring to the column above entitled "Item Numbers". Next, determine the number, type and location of screws by referring to Table I of this AD (see below). Replace each screw at the specified location except that an existing screw need not be replaced if inspection shows that the head has at least one raised or depressed "X" mark. Replace the screws one at a time at the hinge brackets to retain original alignment of the bracket.

B) Any equivalent means of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

TABLE I

Item 1. Two AN502-10-10 screws securing each hinge bracket at leading edge of rudder or ruddervator.

Item 2. Two AN502-10-10 screws securing each hinge bracket at leading edge of elevator.

Item 3. Two AN502-10-12 screws securing elevator control cables to forward bellcrank under pilot's compartment left floorboard.

Item 4. Two AN503-8-8 screws securing elevator control cables to aft bellcrank in fuselage tail section.

Item 5. Two AN503-8-10 screws securing rudder control cables to forward bellcrank under pilot's compartment floorboard aft of left rudder pedals.

Item 6. Two AN503-8-6 screws securing rudder control cables to aft bellcrank in the fuselage tail section.

Item 7. Two AN503-8-6 screws securing aileron control cables to bellcrank under floorboard just forward of the rear spar.

Item 8. Two AN503-8-8 screws securing rudder control cables to forward bellcrank under pilot's compartment floorboard aft of left rudder pedals.

Item 9. Two AN503-8-8 screws securing rudder control cables to the aft quadrant assembly in the fuselage tail section.

Item 10. Two AN503-8-8 screws securing aileron control cables to bellcrank under floorboard just forward of the rear spar.

This AD supersedes AD 74-13-02, Amendment 39-1874 (39 FR 20784).

NOTE: Scheduling accomplishment of this Airworthiness Directive simultaneously with accomplishment of Airworthiness Directive No. 78-22-05 will result in a savings of man-hours.

This amendment becomes effective January 8, 1979.
