REGULATORY TEXT:  
64-13-04 WALTER KIDDE: Amdt. 749 Part 507 Federal Register June 18, 1964. Applies to Aircraft Incorporating Inflatable Escape Slides or Life Rafts Utilizing Walter Kidde Series 1 Actuating Valve P/N's 891771, 891178, 891178-01, 890881-01, 890683, and 890881 Which Have Had Their Seat Assemblies, Walter Kidde P/N 801906 Replaced or Modified With Parts Purchased Since April 1, 1963, and All Series 2 Actuating Valve P/N's 891771-01, 891178-02, 890881-02.

Compliance required as indicated.

During recent demonstrations of inflatable escape slides and life rafts, certain Walter Kidde inflation valves did not provide adequate inflation and required excessive pull forces to actuate the valve. Effective July 1, 1964, all Walter Kidde valves specified herein which are used in escape slides or life rafts installed in civil aircraft shall be modified as follows or in accordance with an FAA Western Region, Aircraft Engineering Division, approved equivalent:

(a) Remove seat assembly Walter Kidde P/N 801906 and install a new nylon seat assembly Walter Kidde P/N 843045.

(b) Functionally test the valve by installing it, along with anti-recoil fitting Walter Kidde P/N 6531, on an appropriately charged bottle and discharging the bottle. During this functional check, the pull load required to actuate the valve is to be determined and is not to exceed 30 pounds. Do not install valves which require a pull in excess of 30 pounds. (NOTE: If Walter Kidde P/N 6531 anti-recoil fitting is not available, the bottle should be adequately constrained.)

(c) Reidentify the reworked valves in accordance with Walter Kidde Service Bulletin No. 168 dated May 8, 1964.

NOTE: Walter Kidde valve P/N's 891771, 891178, 891178-01, 890881-01, 890683 and 890881 which have not had seat assemblies replaced or modified with parts purchased since April 1, 1963, are not affected by the provisions of this AD.

(Walter Kidde Company Service Bulletin No. 168 dated May 8, 1964, with Addendum No. 1 dated May 15, 1964, and Addendum No. 2 dated June 2, 1964, and Boeing Alert Service Bulletins Nos. 2000 dated May 11, 1964, and 2000A dated May 15, 1964, cover this same subject. Note that where the applicability specified in these Bulletins is not the same as that in the AD, the applicability specified in the AD applies.)

This directive effective June 18, 1964.
