To prevent a power loss resulting from defective T2 aspirator hoses, accomplish the following:

(a) Within the next 10 hours' time in service after the effective date of this AD, and thereafter at intervals not to exceed 75 hours' time in service from the date of the last inspection, visually inspect the T2 aspirator hose, P/N MY 20 510.001 or P/N MY 20 510.001A, in each nacelle to see if the hose is collapsed, if the fabric is loose from the hose coil, or if the hose is twisted.

(b) If during the inspection required in paragraph (a) either hose is found to be defective, before further flight, replace the defective hose with a new hose of the same part number, or with either hose P/N MY 20 510.001/2 or hose P/N AWF 1.11.1.2.1.

(c) The repetitive inspections required by paragraph (a)may be discontinued after the installation of either hose P/N MY 20 510.001/2 or hose P/N AWF 1.11.1.2.1 on each nacelle, in accordance with Avions Marcel Dassault Service Bulletin No. 374, Revision 1, dated March 27, 1969, or later SGAC-approved revision or an FAA-approved equivalent.

This amendment becomes effective June 2, 1969.
