6 tm f VERinCATON TESTNG L (CCN-7, Project 1715) *' BS, through the local A FPRO, has been sent a complete package consisty- ng of electrical schematics, operating manuals, and drawings for review and sub- sequent approval. Changes are being made to incorporate Air Force suggestions received to date. Fabrication of the remaining two consoles will be completed after final approval is received by Thiokol. NUCLEAR HARNESS STUY (CCN-54, Project 17116) Physical property testing of the first irradiated specimens were completed and an interim report, TWR-233, was released on 15 Jan The second irradiation specimens are scheduled to be prepared and shipped to Lockheed in August. The test is planned for November SAFETY AN ARMNG EVCE VERFCATON AN VALATON (CCN-6, Project 17117) ii e o ' uring this report period, the Safety and Arming evice Verification and Validation Program Plan was updated and submitted to BS. This plan was technically approved excepting the schedule, for which CCN approval is required. The schedule will be updated and coordinated with BS/OOAMA after all outstanding Figure A's are placed on contract for design, fabrication, or analysis. The Figure A's requiring action are 15.6A, 165.6A, A, A, and A. TT"

7 M )' j E E MOFCATON OF SPECAL TEST MOTORS FOR OOAMA (CCN-96, Project 17119) This project was established in ecember 1966 to rework three motors. The Avcoat is to be removed from 46 forward skirt holes to make the motors compatible with the special <est program. Two motors were reworked and returned to AF Plant 77 on 12 and 27 Jan The third motor was of the 1U323-2 configuration and thus did not require modification. This project is now completed. RP NOZZLE VERFCATON AN VALATON (CCN-87, Project 1712) The existing aft closure mockup, which was used in the Wing -V Nozzle Verification and Validation Program, has been modified for compatibility with the RP nozzle configuration. OOAMA is in the process of sending 14 Figure A items to Thiokol as GFP to support the Thiokol inhouse portion of this program. These 14 items are scheduled to be available to Thiokol in April li>«7. The remaining MGE to support this program is scheduled to be available by late April or early May FABRCATON OF MNUTEMAN H STAGE MOTORS (GTM's) (CCN-93. Project 17121) This project was established to fabricate and deliver four Stage motors according to the following schedule. GTM elivery n a 7 June September February February 1968

8 ' ' i a ( i li The coat proposal and program plan wcie submitted to TZ on 31 Mar Thiokol supported the Technical nterchange Meeting on 15 February and the nstrumentation and n-process esign Review Meetings on 21 and 22 March All of these meetings were held at Boeing, Seattle. Air Force approval was received to use fired cases and closures for this program. The technical evaluation of MNUTEMAN Criteria ocuments is complete except for the Nuclear effects study. A subcontract is being prepared to accomplish this effort. PLANNNG, OCUMENTATON, AN CONTROL VALUE ENGNEERNG (Project 17171) The value engineering program status for this quarter s tabulated below.

9 1. i i: SAFETY AN ARMNG EVCE REESGN AN TESTNG NTERCHANGEABLTY (CCN-86, Project 17172) This effort was completed during the current report period. KR8-9 VERFCATON TESTNG (CCN-86, Project 17172) Twelve KR8-9 safety and arming devices are presently undergoing verification testing in accordant with Thiokol Test Plan TWR-219 to determine conformance with the devices with BS 62-64A requirements. p, Testing of the ES-3 squibs will begin upon approval of the next lot from the vendor. Anticipated delivery of this lot shall be on or before 1 May fl SPECAL TOOLS (CCN-77. Project 1718) The six special tools are currently scheduled to be available for engineering checkout by early April These tools will be used by OOAMA for modifying the KR8-Ü7 safety and arming device to the KR8-9 configuration. EPOT MGE, WNG V ( : PROJECT 1714 Preparation of ECP's WS-133B-THB259, -B26, and -B261 was completed for Figure A's A, A, and A. An ECP is currently in process for Figure A A. PROJECT CCN thru -67. and -78 thru -85 Problems associated with approval of MGE specifications and qualification test supplements were resolved. All specifications and applicable qualification test

10 i! supplements are scheduled to be forwarded to BS/TRW for final approval on or before 15 Apr \i E CCN-61 Air Force acceptance tests for Figure A A are scheduled to be completed during April Upon completion of these tests, the nozzle torque and deflection prototype will be delivered to the Air Force and subsequently used by Thiokol to support the Nozzle Verification and Validation Program. CCN-1 This CCN, received during March 1967, involves the engineering design effort for Figure A A, nspection Gage, Nozzle nsert Seal. esign review (PR/ CR) is scheduled for May, LOGSTCS SUPPORT (CCN , and -89, Project 17176) R 6 AGE (Task 1) A continuing analysis was maintained for Wing V R & AGE requirements atetr. SYSTEM REQUREMENTS ANALYSS (Task 3) Finalization of the system requirements analysis baseline has been delayed pending release of the supplemental agreement for incorporation in the analysis documentation of all OOAMA solutions to Thiokol recommended Figure A's. R& SPARES FOR ETR (Task 4) A priced spare parts list was prepared in accordance with the MCPT document. Partial spares hardware deliveries were made during March Additional spares hardware is scheduled for delivery during April 1967.

Four sets were received last quarter and six this quarter. One set was returned to AF Plant 77 for use in the STM program leaving nine motor sets in storage at the end of the quarter. By authority of CON-15. the storage period was extended through 3 Jun 1967 and ten additonal Stage motors were scheduled for storage.
