## The airworthiness directive

68-03-05 AVIONS MARCEL DASSAULT: Amendment 39-552. Applies to Dassault Fan Jet Falcon airplanes, Serial Numbers 1 thru 107, 109 thru 113, and 115.

Compliance required as indicated.

To detect and prevent binding of the auxiliary hydraulic system selector valve control cables, accomplish the following unless already accomplished.

  (a) Within the next 10 hours' time in service after the effective date of this AD, ground test the functioning of the auxiliary hydraulic system selector valve control cables under simulated flight pressurization deflection of the fuselage floor, in accordance with Dassault Service Bulletin 29-17, Revision 1, dated November 22, 1967, or later SGAC-approved revision, or FAA-approved equivalent. If control cable binding is evidenced during the ground test, comply with paragraph (d) before further flight, except that the airplane may be flown unpressurized to a base where the modification can be performed in accordance with FAR Sec. 21.197.(b) If control cable binding is not evidenced during the ground test, flight test the functioning of the auxiliary hydraulic system selector valve control cables under actual pressurization deflection of the fuselage floor at the next flight, in accordance with Dassault Service Bulletin 29-17, Revision 1, dated November 22, 1967, or later SGAC-approved revision, or FAA-approved equivalent. Passengers may not be carried during this test. If control cable binding is evidenced during this flight test, comply with paragraph (d) before further flight, except that the airplane may be flown unpressurized to a base where the modification can be performed in accordance with FAR Sec. 21.197.

  (c) If control cable binding is not evidenced during the tests required by paragraphs (a) and (b), comply with paragraph (d) within the next 50 hours' time in service after the effective date of this AD.

  (d) Modify the fuselage floor support angles and the upper fairleads, clamps and antichafing strips of the auxiliary hydraulic system selector valve control cables, in accordance with Dassault Service Bulletin 29-17, Revision 1, dated November 22, 1967, or later SGAC- approved revision, or an equivalent approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Region. Performance of this modification at any time makes further action under this AD unnecessary.

This amendment becomes effective February 13, 1968.
