1.3 Parachute Repack Interval
The Strong Enterprises Master Reserve Canopy has a 365-day repack cycle. Your countries laws
may dictate a stricter schedule, check your local regulations. The reserve canopy must be packed
by an FAA certificated parachute rigger with a back type rating, military equivalent, or foreign
equivalent. Alternately it may be returned to Strong Enterprises or an authorized Recertification
Center for complete inspection and repack. If your DHT system is exposed to moisture, excessive
dirt or is damaged it should be inspected sooner than the maximum allowed.
All records must be
kept in accordance with regulations.
Note!
USA current repack regulations can be found in FAA FAR 105.43
1.4 System Description
The Strong Enterprises Dual Hawk Tandem Parachute System is designed for freefall and open
canopy dual instruction applications. It allows two people, a Strong Enterprises Certified Tandem
Instructor in the rear and a student in the front, to jump using one extra large main parachute
while having the back up reliability of a compatible reserve parachute. The packed system, ready
to jump, measures 26 inches long by 16 inches wide by 8 inches thick.
The complete assembly consists of the Dual Hawk Tandem instructor harness and container
assembly, a student harness, the main deployment system, and the reserve deployment system.
All Tandem jumps made on the DHT System must be completed in accordance with FAA FAR
105.45 (or local regulations), this operation manual, and the Training Syllabus for the Tandem
Instructor Certification Course (TICC). Any violation of these procedures will cause revocation of
privileges.
1.4.1 Dual Hawk Main Harness/Container Description
1.4.1.1 Instructor Harness
The harness is made using type 7 webbing. The type 7 has a tensile strength of 6,000 lbs. It is
integrated directly into the container. The harness has integrated reserve risers and drogue risers
that ensure loads are evenly spread throughout. The harness is secured to the instructor by three
adjustable attachment points; one chest strap and two leg straps. Additionally there are two lower
adjustment points that allow users of all shapes and sizes a comfortable and secure fit.
The specially designed 3-D ring was pulled to 11,200 lbs with only a .002” distortion.
Its unique design attaches the student harness directly to the main and reserve
canopies which has multiple benefits. It allows independent loading of the instructor
and student harnesses under the main or reserve canopy. This means that the Tandem
Instructor can fly under the canopy unencumbered by the weight of the student. It
also keeps the students weigh and g-forces from transferring to the instructor harness,
instead it is transferred directly to the canopy via the 3-D ring. In addition, since it
is a solid piece of hardware it isn’t consistently stretching the main lift webbing, thus
eliminating a wear point and extending the life of the harness.
