Document
Tim,
et.
al,
Attached
is
a
merged
document:
old
February
10
full
document
and
February
11
Regulatory
Provision
section
with
the
extension
of
time
for
"
carryover"
engine
families
as
requested
by
Jed
on
February
11.
Please
not
that
I
also
revised
the
second
sentence,
second
paragraph
under
Objective,
Approach,
and
Accomodations
to
read
that
"
most,
if
not
all,"
of
the
testing
and
analysis
will
be
under
contract,
rather
than
"
much."
This
was
consistent
with
the
February
11
Regulatory
Provision
footnote,
which
was
removed
in
this
new
document
(
redundant).
