The following tests verde completed:
T4 ? Autobalamce
Purpose: determine if autobalance is neeueu.
Conclusions autobalance is nee(Jed, occoruiag to the subeentroctor.
Actually, the test proved only that the conligmration goes out
of hatmace it there is no pitch autoisalaace. It did not ascer-
tato if the cause oi imbalance could WA removed mot that the
astehalaace was adequate to correct imbelameei
T5 ? Position Servo
Purpose: teat position servo over range 35 ? 110'i.
Coaclusions performance satisfactory, according to H.
Purpose: detonable it IMC command voltage is 6istorted, an iocats
distortion cause Li existent.
Coaclusion: IMC command voltaic is mot distorted, according to the
subcoatrector.
Actually, rev (Alta shows voltage diatertIosE the test methou
was poor, and the satire test should be rerun. ' (A cheek La
Groumd Ems fl shows distortion exists')
Ti LITS Satire Vibe Drive Mechanism & System
Purpose: learnt tor wear.
' ConclusiosW only the vacuum solenoid slug showed wear, mid this was
*Light.
At the present tine, the fits drive mo_loeser operates satiatec-
tartly it throws a tile loop fsequemtly. The satire film
drive was retested by the eubcoatraeter.
79, T15 & T16 - Shatters
Purpose: tor three ditiereut shutter modifications, determine
vihretion levels and frequencies, double exposure character
and parts subject to wear.
Conclusionas all modifications showed,simtlar characteristics.
30,000 cycles with few double exposures now is possible. Vi-
lorstihh data needs comparisoa with previous dote. A modification
is now being made to tour shutters so all, will be alike.

T17 ? Ground Acoustics
Porroses determine if scoustftatb 0049164 vigr t
sigmlficeatly to observeu iniLht vibrations.
Comclusioms accoustie exaltation creates negligible el
vibretioa
- Temperature Control
Purposes learn how temperefince affects resolution and Local length.
Conclusive: better test comdiamms are requirec to periorm this
test. However, increasing configuration tanpersture while
imaging teas temperature constant appears to *Lightly iSCUSOf
food length; and increasing lens temperature while held1n.
cemligurstion temperature constant greatiy increases Loge
length. It Is apparent that good control. of the t000 barrel
temperature is required.
121Vibration
Purpoesti deteemise what causes 3u cps vibration in scannis LIst
during programmer steps 8 6 1.1, and determine vibration transmie..
lion along axis of pitch stebilisationsoleneio.
Conclusion; vacuum solemoid causes vibration in scanning ilat and
its mount; mod an improved solenoio is needee. The pitch
/texture transmits negligible vibration along axis of the
plunger.
122 ? Autobelasse Malfunction
Purposes deteemlme why autobalanose will not compensate ier at end
low condition.
Conclusion: potentianster R23 was accidentl sis-edjusted.
12.3 - Optical Elements
Purpose; locate optical elements causing poor image as *widowed
on photographic plates.
Conclusion; poor image results true distortion at collbnated
source because of air layering ago turbulence. Also, project
collimators *Wald be tasted in sornal operettas position
with an auxiliary flat, not by rotating eellbnator's own fist.
124 - Cages
Purposes determime cause of eager solenoids failure to rsooao when
configuration IA turned to standby.
Coac1usio* a short circuit in instrumentation wiring bald power
on the oolenoids.

Purpose: ascertain syetem'e optical. quality.
Coeclusion: image has flat* on hard core; entire image was
approximately 204 (free 0 *parr* ot aPPro3tort#11Y 104).
Optical limitation is weal oboes preeeet-iyatam pariorssiscs. -

T26 - Ground Run #1
Purpose: determine Li conageration operates for entirelnission;
lure instrumentation required to ascertain if tomfigeration
operates correctly.
Coadusieee: conilguratiou did not operstseettectiy6 si.nce the
pitch ilexere broke twice, the follow-up potentloweter in the
oblique drive 40TVO broke dowel aed there is SOW variation
in the 1PMC command voltage. Also, to photographically chock
performance, a thuntfield,d.c. motor is seeded on the eollimator,
sad the room should have a stable temperature, Alia should be
about 65?Y if the lens barrel heaters are also checked.
-(Two other check* were made; The modifiedAmmesum solenoid
did not reduce transient vibrations La the SOOMMill fiat;
and the date restore/1r wee in good focus.)
T27 - Fitch Stabiliser Failure
Purpose: determine cause of lack of output from stabiliser.
Conclusions cleaning; comnections es printed circuit boards restores:
operation.
T26 - Files Drive Cheek
Purpose: determine cause of tendency to throw loop an le it side.
Conclusioa: looping caused by ose et mere of; faulty microswitch,
imcorrect shimming, and gum on plates'.
T29 4, Overload caused by shutter
Purpose: determine why circuit breakers actmate when *batter is
installed.
Conclusion: massive short circuit in shutter, probably caused by
careless rework of abutter.
Oblique Drive
Purposes determine why oblique drive goos to left limit stop
without C commaed signal.
Conclusion: there MOS an open circuit is the fellow up potentiometer,
caused by a mechailtal breakage.

It is proposed to embotitate a very thorough evaluation of reliability
Lor th4 present inefficient program'. The ilroposed evaluation would be
made with the combined emaimommims talents of the prime contractor sad
the subcontractor.
For raaaollus of ifti414acL both bsetmic.al and financial, the work would

PUSOMMS4 AND GANISAL PLAN
The premiss difficulties with the cemflpdrotion should be removed in
the Will4 SIMUM4r that the vibration problem* wore removed - by an
engineario4 evaluation and minor modification* ? state this is the
most officio:tut and economical method. The list of.recoired personnel

since the require.. talaats are raaly available:as Aseeed (instead of
as available to travel) and since a much seallertravel effort is

'should be available full time to pro-
Vida tho benefit of their familiarity with the present and past statue
of the coaliguratiom and its campooents. This should be extremist, villas
able for the expeditious completion of the proposed program. flovevor,
the prime aentrector can visualize no value in retentioa oi other sub..

would, however, plan to procure modified shutters trim the anbcootrector,
