Althouth E- 8 had indications of a previous Hon1tor check No- Go it was not the cause of shutdown at this time .

could have ,caused a No- Go ....ould have been 10s5 of confirm codes.
This type of fault 'Would not have produced a VRSA c,hannel 9 and
12, but only a channel 9 .
This'.infonnation elir.d.nated the No~o

theory as the cause of the incident.
(u)
As stated eariIer, all 10 launch facilities shutdown ~~th a
VRSA channel 9 an"d 12 (G&C No-Go and Logic Coupler No- Go) recordings .
Because of this consistency considerable invest1gat1o~ was ex
pended in the Logic Coupler area .
In the channel 50 anal ysis it
was sho....n th2.t the guidance section did not experience a Ho- Go
and therefore, it was felt th~t the VRSA channel 9 report was
not valid . It is possible} however,' for the Logic Coupler to

generate both of these No-Go .indications.
{§!feU
The logic of the coupler ~~s studied by the investigating
team in en efiort to identify a method by which both VRSA 9
and 12 could be ~~tivated. The opinion of the team was that
external generate~ signals caused the generation of these two
channels and shutdoftn of the launch facilities .
The possibility
of this is very remote due to the £act that all 10 couplers
~ould have to fail in the flight ~thin a few seconds of each

After performing the tests, it \(as decided that com.i':lerical f" " '-, I' 'i .: power switching operations \(ere not the cause of 'the EFl ight shutdown. This was based on the follo~~ng reason~ . Other flights fed by the Hilger substation ~ere not affected . Similar shut downs occurred in A Flight LFs ~hich were supplied by power not only fro~ separated substations ~ but also, from separate feed lines froin the generation station.

Representath'es from the Boeing Company, Autonetics, OOAMA, and 15th AF attencied . 43 ~(U) The group decided that insu'fficient data on the incident existed to resolve the problem. or for adequate engineering an~i.ly ~is without 2.cditional testing . The present data suggested that the problem Kc.S a "'jin&; I peculiar problen. Since the OOAH.!\. E>..-permintal Test Facility (E'Ir') 'h"a.s not a Hing' I type, it was necessary for the expermnts to be conducted at l-iall:istrom. Furt..l't er analysis of the proble;:!. sho...·ed that e;':permints \wuld be of no real value until a i\'o-Go Hode cculd be reprod~ced atleas.t 44 at a 1F level . ~) It was decided by the group to first cevelop a lo'ay to re produce a Nc":o Eade at the LY level then at the Launch Control Facility (Len level before a test could be made at HallI'.strom. The group was to rec:;mYene at Boeines' Seattle plant on 4 April 67 for develop!!lent of a -"2..y to safely reproduce a No-Go effect. Thu plan ,.;il.~ to 00 developed at the N~tr:ork.

10 separ~te applications of a sin~le Pulse, ..auld cause the system 06 to shut dOrm '\>Jith a Channel '1 .~ 12 1\'0- 00 6 ~(U) Subsequent testing at Autonetics has resulted in the follow ing explanation of what proo,~lf happens in the Coupler Logic Dra~er . The Pulse inserted is lor.g enough to initiate t~ Coupler Self test sequence r:ithin the C-S3P. HOt,ever, it is not :>f long enough dUl'ation t~ enable control lines to the cOI'i'.puter to place the computer in a L:oupler test loop }lode . 1'his causes the Coupler to issue a sequence e4ror due to lack of coincide~ce bet;.;een G!:.C and Co~plE'r i'~des . This sequence error, toeether with the action of tl';O other flip flop outputs (H- 17 (oi. 11- 20); is 47 sufficient to initiah the CO'J.pler and G&'C No-Go shut do·,m . ~(()) The effort at B':Jeing !·2,it ;;as to determine the source and most likely path of noi!;;e Pulse to the LoBic Coupler . The results fo the Electro j·;a.gnetic Pulse (:!;~1P) testin& at the IF and Hing r" indicated that t:-.e Sensitive Iniormation riet;.:ork (SIN) "r:e:re sus . 1:8 cept1ble to noi~e of the type that could ilave caused the !>l"':Jblern. ~(U) The SIN lir:.es &0 only fron t..~ ICC to all of the IF! s in the flight, 'I...hie:" could ex?12in the flight perculiar aspect of 491 the problem.

The best possible s~urce of the noise Pulse, so far in the analysis, HuS the transformer f~lure ,,-hich occurred at a stock ....'.ltering throuE;h the 3cho fli~ht area . The !'horting to ground of the single phase transforrr_er r.:ay have unbalanced the three phase Ilylt connected system enough to cause ground currents to flo'", back to the genera.tor. The Eardene.d Intersite Cable (l-iIC) shields ,.'O"u.ld provide a path for the gfound current thus inducing volt 50 age Pulses on the SIN lines to all LF1s. ~ (u) Testing at i::t~ has proven that there is sianificant coupling bet"een the shields ~f the SIN lines and the Self Test Co:nmaoo 51 (STC) line into the C- 53P 1~8ic Coupler. Ie< lU) A conference was held at Boein~ on 18 April 61 for the task te~:'!1 to revieH the preliminary test plan for LF, E- 18, a.t Ealm.stroGl.
