Subject: DN55000..I PARACHUTES
Several pilots have problems with the DN55000-1 parachutes because
the stiff spreader bar across the top of the shoulders interferes with
the neck ring of the helmet. This forces their head forward and also
prevents them from moving their head aft to the headrest for ejection
if necessary.
We have modified an old pack to mock up a suitable spreader bar con-
figuration which would cure the problem. This is shown in the enclosed
photos. We have not adversely affected the function of the spreader
action and have made the pack more comfortable for the pilots.
The following is a blow by blow description of our modification:
1. Horizontal Spreader Bar
A. Remove stitching around two ends and top of
drogue container from parachute pack.
B. Cut stitching on spreader bar and back diagonals.
Pull spreader bar down one inch at center of pack,
forming a shallow "V" shape, and restitch.
Back Diagonals
A. Cut stitching on fabric sleeves at shoulder area.
B. Pull fabric over one inch and resew.
A. Cut excess fabric out between diagonals down to toil
edge of pack and refinish raw edge with binding tape.
4. Tie Loops
A. Attach two tie loops on end flaps of drogue container
and top flap of main parachute pack so as to hold
drogue container from rolling forward.

Tack drogue release housings down with type "1" thread so
as to break away on opening shock.
In particular, we would like to have this modification accomplished on
twonarachute-5 as soon as possible for use by our company pilots at
25X1A
I am sending a copy oII this letter to to keep hirn informed 25X1A
of our request. I believe this nodi desirable for all
pilots and perhaps could be scheduled in during your normal factory over-
haul of the parachutes.
Best regards,
