7.18.2 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
Before Flight” streamer is attached to the pin.
WARNING!
Always remove the safety pin of the BPRS before engine start-up and re-in-
sert before leaving the aircraft.
WARNING!
After maintenance has been performed or any other time the system has
been safe tied, operators must verify that the pin has been removed before
further flight.
