HAS SUBMITTED A SUMMARY OF BOARD PROGRESS TO DATED 29 MAY 63.
IT IS QUOTED BELON FOR YOUR INFORMATION.
A, ENt;I EESm AL l ENGINE ACCESSORIES HAVE BEEN RECOVERED
AND SENT TO UADq CONN. FOR TORO MAJOR COMPONENTS OF COM-
PRESSOR AND TURBINE F OM BOT4 ENGINES HAVE BEEN EXARINED
FOR ROTATIONAL DAMAGE',, LEFT HAND ENGINE S4OVS SUBSTANTIAL
ROTATIONAL L` ;=PAGE IND: CATIVE OF HIGH RPM All IMPACT, RIGHT HAND
ENGINE SHO V~:; LITTLE ROTATIONAL DAMAGE INDICATIVE OF LO RPM
AT IMPACT, EXTERNAL EXAMINATION OF ENGINES HAS NOT SHOWN ANY
INDICATION ENGINE FAILURE. INVESTIGATION VILL CONTINUE IN
AREA OF ACCESSORIES; BASIC ENGINE AND AFTERBURNER, AND FUEL
SYSTEM.
9m INS, AT SOME INSTANT OF TIME BEFORE IMPACT, THE INS
PLATFORM LOST REFERENCE, THE SYSTEM WAS APOARENiTLY FUNCTIONING
PROPERLY AS THE INITIAL DECELERATION BEGAN? THERE IS NO EVIDENCE

OF SYSTEM NALFUNC T IO OTHER THAN THE POSSIBLE LOSS OF POWER BE-
TWEEN DECELERATION AD IMPACT. ALL READOUT PANELS WERE
JAMMED AT REASONABLE VALUES AND CORRESPOND TO THE
APPROXIMATE COORDINATES OF IMPACT. JUDGING FROM THE CONDITION
OF THE PLATFORM STABLE ELEMENTS IT WAS INVERTED ON IMPACT, WHIC '
WOULD NOT BE THE CASE IF THE SYSTEM WERE FUNCTIONING PROPERLY. THE
CONDITION OF OTHER ASSOCIATED EQUIPMENT IN THE SYSTE T INDICATES
THAT IMPACT OCCURRED IN A NOSE DOWN, INVERTED ATTITUDE. THE IN-
DICATED GROUND SPEED GENERATED BY THE SYSTEM WAS JAMMED AT 308

C. MAINTENANCE AND AIRCRAFT RECORDS: INSPECT ION OF AIRCRAFT
MAINTENANCE RECORDS DID NOT REVEAL ANY FACTOR WHICH IS CONSIDERED
CONTRIBUTORY TO THE CAUSE OF THE ACCIDENT.
Da OPERATIONS GROUP3 CREW RESTS PHYSICAL CONDITION, PSYC4OLO-
CICAL FACTORS AND QUALIFICATIONS HAVE BEEN STUDIED AND DO NOT
APPEAR TO BE A FACTOR IN THE ACCIDENT. WEATHER WAS AS FORECAST
AND DOES NOT APPEAR TO HAVE BEEN A PRIMARY CAUSES BUT MAY HAVE
CONTRIBUTED TO THE ACCIDENT. THE PLANNED GROUND TRACK WAS
FLOWN ESSENTIALLY AS BRIEFED WITH ALTITUDE MODIFICATIONS
DUE TO CLOUD CONDITIONS. WEATHER OVER CHECK POINTS
PRECLUDED VISUAL IDENTIFICATION OF AUSTIN9 NEVADA DURING BOTH
CIRCUITS OF THE ROUTE AND ALSO OF WENDOVER9 UTAH9 DURING THE SECOND
CIRCUIT. VISUAL IDENTIFICATION OF OTHER CHECK POINTS CONFIRMED

LISTED BELOW STRUCK THE GROUND IN AN INVERTED ATTITUDE ." THERE
DOES NOT APPEAR TO HAVE BEEN ANY PRIMARY STRUCTURAL FAILURE..
THESE ITEMS LEFT THE STRUCTURE BEFORE IMPACT:
(1) PILO ? S CANOPY
(2) PILOT'S SEAT AND JETTISONING HARDWARE.
(3) MIS>CELLANTC)US PIECES OF COCKPIT TRIM. INSULATION.
RECORDER AND FLIGHT CORDS.
(4) SMALL FRAGMENTS OF HONEYCOMB MATERIAL.
2. RECOMMENDATIONS:
A. EVEN THOUGH THE FOLLOWING ITEMS MAY OR MAY NOT HAVE CONTRI49
BUTED TO THE ACCIDENT UNDER INVESTIGATION. IT IS RECOMMENDED THAT
THE FOLLOWING ACTIONS BE TAKEN PRIOR TO CONTINUATION OF FLYING
WITH 121 AND 124.
(1) RECONFIGURE THE ELECTRICAL SYSTEM SO THAT INVERTOR
NUMBER TWO WILL AUTOMATICALLY AND, IF NECESSARY'S MANUALLY CHANGE
OVER TO REPLACE A FAILURE ON NUMBER ONE INVERTOR, THIS IS BEING DONE.
LAC WILL GIVE BOARD A STATUS REPORT 3 JUNE ON THIS aUBJECTo
Q) INSTALL A CRASH RESISTANT FLIGHT RECORDER FOR USE
DURING TEST AND TRAINING PHASES OF THIS PROGRAM THAT WILL MEASURE
