5. Fasten a 36 inch loop of suitable material such as fishing line, braided wire, or other similar
material having a breaking strength of at least 100 lbs., diagonally between two of the
screws. Then fasten another loop diagonally between the other two screws, adjusting the
length of the loop so it exactly matches the first.
6. Hook a calibrated force gauge through both loops and apply a sustained pull for at least 3
seconds in each of the other three directions (upward, sideward and forward) at the above
calculated forces (i.e. 20.4 lb. upward, 15.3 lb. sideward and 61.2 lb. forward).
7. Examine the support structure carefully. If there has been damage or permanent deformation,
the structure is not suitable and must be replaced with one that is strong enough to withstand
the test loads. Examine all aircraft stringers, bulkheads and skin surfaces, which may have
direct or indirect contact with the fabricated shelf. If it is determined that no damage or
permanent deformation has occurred, the structure is of sufficient strength and the GTX 32
equipment rack may be permanently mounted on it.
