HSWL requested deferment of changes to the EMU Rotation Plan to the 4/4/01 EHB, which will include crew issues and addition of 3rd EMU to 8A.
- USA SAFER Flight Logistics Plan XA/Anh Huynh
- EHB Action Status XA/D. Roberts
Changes to the USA Safer Flight Logistics Plan were presented. The plan was revised to substitute S/N 1006 for S/N 1003 on STS-100 and to substitute with S/N 1003 accordingly on subsequent flights.
This item was deferred.
