The release unit bolts to the bottom of the bomb rack
frame near the center. Before the hook tie linkage is
cocked, you must cock the release unit plunger. The
electrical cable assembly supplies 28 volts of dc through
a four-pin male connector. Three types of electrical
release units are used-the Aero 7B release unit, the
Aero 7B-1 release unit, and the linear electromechanical
actuator (LEMA). The external difference between the
Aero 7B and Aero 7B-1 is the two-piece plunger barrel
on the Aero 7B-1. The LEMA is similar to the Aero
7B-1 release unit. You can identify it by the decal
located on the release unit.
There are two arming solenoids at the bottom of the
bomb rack frame, slightly forward of the center. The
arming units are electrically controlled and
mechanically operated continuous-duty solenoids.
They provide fully selectable arming for nose, tail, or
nose and tail when weapons are armed by arming wires.
Arming is selectable in flight by the pilot. The pilot also
has a safe selection, which does not energize the arming
The weapon/store is suspended from two
suspension hook assemblies protruding from the bottom
of the bomb rack. Each hook latches independently.
You mount it in the bomb rack frame by using a pivot
pin. Each hook is made from chrome-plated steel or
stainless steel. It has a bushing in the pivot hole, a latch
pin engaging the hook tie linkage to latch the hook, and
a threaded spring stud to attach a spring to preload the
hook in the open position.
A manual release cable assembly is located at the
center of the bomb rack. It consists of a pull ring and a
cable extending for the depth of the bomb rack. The
cable is attached to a manual-release link assembly or a
manual-release lever located at the bottom of the bomb
reck. When the pull ring is connected to the aircrafts
externally routed manual-release cable, the pilot has the
option of manual release.
The release-linkage assembly, located at the center
of the bomb rack, contains a release bell crank and bell
crank link, a sear link, and two attaching pins.
The hook tie linkage assembly extends end-to-end
on the bomb rack. It contains a bumper and four moving
parts-two latches and two links, which are set between
two hook tie links. The tie linkage latch link contains
cutouts so you can insert the lock-link assembly and the
screw holding the latching pin in place.
The electrical cable assembly consists of five leads.
Two leads are attached to the solenoids. The remaining
leads are routed along the top inside surface of the bomb
rack. They terminate in a female connector that mates
with the release unit.
There are two accessories for the Aero 65A bomb
rackan Aero 1A adapter assembly and a safety
interlock mechanism. These accessories are issued as
required. They do not come with the bomb rack.
Aero 1A Adapter Assembly
The Aero 1A adapter assembly (fig. 10-2) lets you
load and carry weapons/stores that have suspension lugs
spaced 30 inches apart and weigh up to 2,000 pounds.
When you install two Aero lA adapter assemblies on the
bomb rack (one on either end), the adapter assemblies
let you attach the bomb rack to the aircraft pylon
assembly. The Aero 1A adapter linkage attaches to the
bomb rack. The movement of the Aero 1A adapter
suspension hooks corresponds to the movement of the
bomb rack suspension hooks. If you need more
information about the Aero 1A adapter assembly, refer
to Bomb Rack Adapter Assembly Aero 1A, NAVAIR
Safety Interlock Mechanism
The safety interlock mechanism is an in-flight,
operable bomb-rack lock (IFOBRL) (fig. 10-3). It
provides additional safety when the aircraft carries
