BALLISTIC PARACHUTE RESCUE SYSTEM (BPRS)
The aircraft is equipped with the Ballistic Parachute Rescue System (BPRS)
designed to bring the aircraft and its occupants to the ground in the event
of a life-threatening emergency. The system is intended to save the lives of
the occupants but will most likely destroy the aircraft and may, in adverse
circumstances, cause serious injury or death to the occupants. Because of
this it is important carefully to consider when and how you would use the
system. !
WARNING :
The parachute system does not require electrical power for
activation and can be activated at any time. The solid propellant rocket flight
path is upward from the parachute cover. Stay clear of parachute canister
area when aircraft is occupied. Do not allow children in the aircraft unattend-
ed.
7.18.1 SYSTEM DESCRIPTION
The BPRS consists of a parachute, a solid-propellant rocket to deploy the
parachute, a rocket activation handle, a composite container and a harness
connecting the canopy to the wingbox structire.
A composite box containing the parachute and solid-propellant rocket is
mounted to the airplane structure behind the right seat and is divided from
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 6/600 SD SPEEDY. The
parachute system attaches with 2 belts to the aft fuselage/wings pins and
belonging bulkhead. When deployed, the aircraft is suspended under the
parachute with approx. 20° nose down attitude. The parachute system is ac-
tivated by an activation handle, located between the occupant seats on the
tubular structure 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 com-
plete parachute package out of its container at once.
Maximum demonstrated parachute activation speed is 170 KTAS.
