ABSTRACT:
A longitudinally central portion of a weaponry support plank is secured to the cabin area floor of a McDonnell Douglas 500/530 helicopter using a support and reinforcing system associated with forwardly and rearwardly disposed pairs of stiffening ribs anchored to the top side of the floor. Opposite end portions of the front and rear rib pairs are removed and are laterally enclosed in and anchored to elongated reinforcing structures each having opposite ends generally aligned with the opposite ends of its associated shortened rib. End members are anchored to the floor at the opposite ends of each pair of shortened ribs and are also anchored to the opposite ends of their associated reinforcing structure. Two front support strut members have upper sides fixedly secured in a spaced relationship to a front side edge of the central plank portion, and two rear support strut members have sides fixedly secured in a spaced relationship to the rear side edge of the central plank portion. The undersides of the support strut members are removably and pivotally secured to the end members by expansion pins extending along axes transverse to the stiffening ribs. In an alternate embodiment of the support and reinforcing system the front support strut members are provided with rearwardly projecting extension portions that are anchored to reinforced opposite end portions of the central floor stiffening rib.
