Detailed recommendations for the improvement of the personnel restraint systems in the U. S. Army CH-47 aircraft are presented. The recommendations pertain primarily to the strengthening of existing components. The modifications proposed indicate the following strength improvements 1 Cockpit-the crews restraint system is increased from an 8-12G value to 25-30G value 2 Troop Compartment - the troops lap-belt attachments are increased from a 10-15G value to a 22-28G value. The above strength increases can be achieved with a weight increase of 7 pounds per aircraft and at a cost of approximately 300 per aircraft. The following information is included in the report 1 Engineering - strength analysis of proposed modifications 2 Administrative - a cost and weight summary of proposed modifications 3 Detailed engineering drawings are available as a supplement to this report a parts procurement or manufacture - drawings necessary for the procurement or manufacture of retrofit kits. b installation procedure - sufficient information is included in the drawings for installation of retrofit kits by army personnel.
