See list belowJanuary 14, 196969-PA-T-5APA/Chief, Apollo Data Priority CoordinationProcedure for LM aborts immediately after landing are terrible!
Clarke Hackler of Guidance and Control Division uncovered a rather alarming situation which we've discussed a little at our Descent Abort Mission Techniques meetings. He briefly states the problem quite nicely in the attached memo, which I thought should be brought to your attention.
The four switch settings involving three switches which Clarke refers to are:
a. The ENG STOP switch is set at probe contact.
b. The ENG ARM switch is placed from the DES to OFF position.
c. The ENG STOP switch is reset.
d. The ABORT STAGE switch is set (after raising a plastic overlay).
