EV CREW SUPPORT REQUIREMENTS

The following groundrules apply for establishing equipment quantities to
support the EV crew.

a\. Sufficient quantities of SSA equipment will be provided by NASA to
assure a 90 percent probability of fitting an EV crew population of 101
members with HUTs and an 80 percent probability of fitting the same
population with the other sized SSA equipment. In addition one (1) spare
HUT of each size is to be provided. Spares for the other SSA sized
equipment are to be selected by NASA on a non-dedicated basis.

b\. NASA will provide sufficient flight SSA equipment to support the
following flight and crew familiarization altitude chamber runs
requirements.

1\) A flight rate of up to one (1) flight per month.

2\) Flight equipment quantities to support the same size items on three
(3) back-to-back flights.

3\) A crew familiarization altitude chamber run rate of up to one (1)
per month will be accommodated.

c\. Hard upper torso (HUT) usage for flights are governed by the
following:

1\) Extra-small HUTs are not to be provided or considered.

2\) A maximum of one (1) small HUT may be flown on any given flights.

3\) There is no restriction on the flight use or mix of uses for the
remaining HUT sizes (Med., Large, and Extra Large).

d\. EV crewmembers are to be identified a minimum of twelve (12) months
prior to the launch of their assigned flights.

e\. Glove quantities are to be based on the following:

1\) Twenty-five percent of the EV crewmembers will "re-fly" and have
acceptable flight gloves.

2\) Seventy percent of the remaining 75 percent will require custom
gloves consisting of one pair for training and one pair for flight.

3\) Backup gloves, if required, will be drawn on a best fit basis from
existing inventories.

f\. A quantity of 12 each, or pairs as applicable, of non-sized class I
flight items and nine (9) each, or pairs, of class III WETF items as a
minimum will be maintained in FEPC inventories.

g\. NASA will provide EMU training equipment to support eight (8)
training events in two (2) days at JSC with two (2) shifts between uses.
Quantities will be available to obtain the same probability of fit as
required for flight equipment.

h\. No dedicated spares are to be provided for training equipment.

i\. The usage rules of flight HUTs also apply to training HUTs.

j\. A minimum of one (1) of each size will be provided as a sizing
verification unit.
