1967.03.30 - The Apollo 204 Review Board accepted the report of its Sequence of Events Panel


The Apollo 204 Review Board accepted the report of its Sequence of Events Panel (No. 3), which had been charged with analyzing data from immediately before and during the January 27 fire, including digital, analog, voice communications, and photography.

The data was required to display significant events as they occurred with the precise time tag. Time histories of all continuous or semicontinuous recorded parameters and correlation of parameter variations and events were to be recorded, as well as interpretation of the analysis results. Where pertinent, normal expected variations were to be compared with those actually obtained.

Panel 3 had served as a separate panel from January 31 through February 23, when it was merged with the Integration Analysis Panel (No. 18). Panel 3 reported one finding and one determination:

Finding

The data recorded from the spacecraft and ground instrumentation system during the Spacecraft Plugs-Out Test were found to be valid except for three brief dropouts after 6:31:17 EST, January 27 (13 seconds after the pilot reported "fire in the cockpit"). All onboard data transmission ended about 6:31:22 EST.

Determination

The onboard instrumentation system functioned normally before and during the initial phase of the fire. There were no indicated malfunctions in any of the instrumentation sensors during this period.
