After NASA reviewed the LM vibration environment and previous acceptance test decisions, Grumman recommended that complete vehicle vibration testing with externally mounted acoustic horns should be continued beyond LM-2; that wider use of thermovacuum testing at the component level be considered; and that the LM designated for the lunar landing mission be subjected to complete thermovacuum tests either at MSC or KSC.
MSC concluded that
- for schedule purposes it would plan to continue complete vehicle acoustic testing after LM-2; however, implementation of this decision would depend on the results of the LM-2 testing;
- MSC would reexamine the application of more widespread thermal testing at the component level; and
- the Grumman proposal to subject the LM designated for the lunar mission to more testing than earlier manned flights was unacceptable. Past experience had shown that earlier vehicles should always have more testing than later ones.
