NOTE
Keep in mind that a badly broken apart aircraft may
have already put the activating housing into a stretched
state that may be close to detonation.
(2) Identify the rocket motor launch tube (photo below).
Note where the activating housing screws onto the base
of the launch tube.
(3) Using a Felco-brand cutter (identified below), cut the
activating housing at the base of the launch tube where
the activating housing screws onto the launch tube.
(4) Remove the still-live rocket motor to a secure place
and contact BRS for further directions about permanently
disabling the rocket motor.
2-63. The term ballistic in this reference has nothing to
do with guns or ammunition. Instead it refers to a means
of extracting a parachute. For Ballistic Recovery Systems
(BRS) today, this means a rocket-deployed emergency
parachute system. The term recovery has nothing
to do with recycling ammunition, but instead means
bringing a payload to the ground via parachute canopy.
[National Transportation Safety Board states: “CAPS
uses a solid-fuel rocket (stored in a compartment in the
aft fuselage of Cirrus airplanes) to deploy a 55-pound
parachute that allows the airplane to descend in a level
attitude at about 26 feet per second. To activate the
system, a pilot pulls an overhead handle in the cockpit
(after removing a metal pin that secures the handle in a
stowed position). The aluminum CAPS rocket, which
weighs 1 pound 6 ounces, contains 1 pound of propellant,
fires for 1.2 seconds, and accelerates to over 100
miles per hour in the first tenth of a second. It produces
peak thrust of about 300 pounds. Under normal conditions,
CAPS is well secured and is not prone to accidental
firing. The rocket will only fire if the activation
handle in the cockpit is pulled with sufficient force (about
35 pounds for Cirrus airplanes 6). However, the system
can be less predictable if an airplane has been in an
accident.”]
Used as intended, these BRS-brand emergency parachute
systems have saved over 150 lives. However, the
pilot must elect to deploy the system, completely different
than, say, an airbag which deploys automatically
when certain conditions develop. Because the pilot (or
his passenger) must pull the activating handle, sometimes
the units are not used.
The pilot may have felt he could rescue the aircraft from
its predicament. Or he may have been unable to deploy
for physical or other reasons. Regardless of why a ballistic
parachute was not used, the fact remains for safety
personnel that when handling an accident where a BRS
unit was not deployed, a potentially dangerous device
now confronts them.
2-64. Consider the rockets extremely dangerous. While
the total firing period is only one second, someone in
the path of an escaping rocket could be seriously injured
or killed. These are powerful little rockets (about
one and a half inches diameter and 10 inches long) that
work very efficiently.
The rocket motors are activated by pulling a firing handle
in the cockpit. Both parachute container and handle
should be permanently fastened to the aircraft. However,
in an accident, things come apart. Should the sections
of an airplane be broken apart, the activating hous-

ing may become stretched tight. If the parts separate
enough, the unit could be detonated even with the blast
handle still secured by its safety pin.
The danger to safety personnel may now be more obvious.
A rescue worker who disregards the position of the
ballistic parachute system, or who moves the aircraft
without determining the existence of a ballistic parachute
system may put him or herself in considerable
jeopardy.
BRS staff members have worked with several NTSB
people as well as rescue personnel at airshows in Florida
and Wisconsin. BRS company employees have assembled
some information for safety personnel to disarm
these systems.
When an accident happens, emergency personnel may
need to call for assistance.
Fortunately, those of you reading this article have the
luxury of time to respond. The accident has not yet
occurred. Given enough time, BRS has a simple solution
to offer. First, we need to provide a little background
information.
2-65. A BRS unit is comprised of four major elements.
The first thing emergency people will see may be a red
firing handle. This will usually be located near the victims
as it should be close to the pilot so it can be operated.
The red firing handle will connect to an activating
housing, an armored yet flexible shaft that links the firing
