NATURE OF PROPOSAL:
The drag chute doors will be modified as follows:
1. Increase the space for the drag chute by eliminating the forward
bulkhead.
2. Increase the gauge of the outer skin from .025 to .040 aluminum,
and the remaining bulkheads from .032 to 051 aluminum.
Add an .063 aluminum inner skin along the vertical sides of the
doors.
4+. The gauge of the bottom deflector skin will be increased from .020
to .032 steel.
Re-design the striker plate for the latch lock to obtain adjustability
so that the correct'' adjustment in the locked position will be maintained.
6. The locking mechanism will be modified in order that the doors can be
looked from the outside by direct engagement through a slotted screw.
Existing lock and cable system to be used.
7. A tongue type interlock will be incorporated to eliminate fore-and-aft
vibration to prevent inadvertent door opening during flight.
8. Prepare and issue a Service Bulletin and fabricate kits.
