AIRPLANE DESCRIPTION
the baggage compartment. There is an exhaust tube leading the activation
gasses from the rocket to the outside (bottom) of the fuselage, the exhaust
is placarded.
The type of BPRS is Galaxy Rescue System GRS 6/473. The parachute sys-
tem attaches with 2 belts to the aft fuselage/wings pins and belonging bulk-
head. When deployed, the aircraft is suspended under the parachute with
approx. 20° nose down attitude. The parachute system is activated by an
activation handle, located between the occupant seats on the tubular struc-
ture overhead. The handle is pulled forward and/or downward for activation.
A rocket is ignited that leaves the fuselage through a special egress panel
directly behind the main bulkhead. The rocket pulls the complete parachute
package out of its container at once. Maximum demonstrated parachute
activation speed is 170 KTAS.
7.15.2 ACTIVATION
The BPRS is activated by an activation handle, located between the occu-
pant seats on the tubular structure overhead. Pulling the activation T-handle
will activate the rocket and initiate the BPRS deployment sequence.
To activate the rocket, two separate events must occur:
1
Pull the activation T-handle from its receptacle. Pulling the T-handle
removes it from the o-ring seal that holds it in place and takes out
the slack in the cable (approximately 5 cm of cable will be exposed).
Once the slack is removed, the T-handle motion will stop and greater
force will be required to activate the rocket.
2
Clasp both hands around activation T-handle and pull straight for-
ward/downward with a strong, steady, and continuous force until the
rocket activates. A chin-up type pull works best. Up to 200 N force,
or greater, may be required to activate the rocket. The greater force
required occurs as the cable arms and then releases the rocket ignit-
er firing pin, which ignites the rocket fuel.
NOTE: Rapidly pulling on the activation T-handle greatly increases the pull
forces required to activate the rocket.
A safety pin is provided to ensure that the activation handle is not pulled
during inadvertantly; for example, the presence of unattended children in
the airplane, the presence of people who are not familiar with the BPRS ac-
tivation system in the airplane, or during display of the airplane. A “Remove
