60-02-03 BOEING: Amdt. 79 Part 507 Federal Register January 15, 1960. Applies to the following 707-100 Series Aircraft Only: Serial Numbers 17586 through 17591, 17609 through 17612, 17628 through 17650, 17658 through 17672, 17696 through 17702, 17925 through 17927.\n \n\tCompliance required by June 1, 1960.\n \n\tBecause of the hazardous condition caused by water injection system failures, the following modifications shall be accomplished as indicated: \n\n\t(a) Relocate the water inlet valve switch from the co-pilot's panel to the flight engineer's panel and add four transient position blue indicating lights (one for each valve). Install a placard for nomenclature.\n \n\t(b) Change water booster pumps start switch on co-pilot's panel to a two-position toggle switch. \n\n\t(c) Install an appropriate placard adjacent to the water booster pump switch to specify that this switch is to be turned off after the water pressure lights go out at the end of water injection. This is necessary to avoid damaging the tank mounted water booster pump after water runout. These modifications are included in Boeing Service Bulletin No. 194 (R-1) dated June 19, 1959. \n\n\tRevised March 29, 1960.
