1967.04.27 - Reservations on wiring in Apollo CSM 101


Astronaut Donn F. Eisele. a member of the Block II Wiring Investigating Team, wrote the ASPO Manager his reservations as to whether the wiring in spacecraft 101 could be salvaged and made safe for flight.

"To render positive assurance of wiring integrity, strong consideration should be given to replacing the entire 101 harness with a new, like item-made to the same drawings as the present harness, but constructed and installed under more rigorous quality control measures; and using non-flammable materials. The replacement harness should be installed at the outset in protective trays and covers now being implemented at NAA (North American Aviation). A wiring overlay could be installed later, to accommodate recent spacecraft design changes, if adequate space is provided in the protective trays, connector support provisions, etc. This should provide a harness of good quality and known condition to start with; and the protection and quality control measures should keep its integrity intact." (Eisele was the pilot on the Apollo 7 mission - the first manned Apollo mission and the one on which spacecraft 101 was used.)
