See list belowJAN 16 196868-FM-T-8FM/Deputy ChiefAGS accelerometers may not work.
1. Apparently, there is a basic problem in the LM Abort Guidance System (AGS). Although it is not widely known, there is a rumor the accelerometers do not work and it is highly likely G&C Division will elect to procure the AGS accelerometers from another source. Since it is too late to obtain and incorporate them into the system immediately, LM-3 and LM-4 will use the original accelerometers in the AGS. I believe it is their intention to select the best ones available in hopes of avoiding an unoperable system.
2. I am writing this note since, if the AGS is considered undepend- able on LM-3 and LM-4, this fact should be taken into account in mission planning and data priority decisions for those missions. For example, it seems highly undesirable to plan on utilizing the AGS for executing maneuvers in a nominal mission as is currently planned on Mission “D”.
