## ACCIDENT SCENE SAFETY

- RECOGNIZE THE PRESENCE OF A BRS SYSTEM
- AVOID THE POSSIBILITY OF INADVERTENTLY INITIATING THE SYSTEM
- TAKE THE NECESSARY STEPS TO DEACTIVATE THE SYSTEM

## A BRIEF HISTORY...

**BRS WAS FOUNDED IN 1980 BY BORIS POPOV, WHO CREATED A WHOLE AIRCRAFT PARACHUTE RECOVERY SYSTEM FOR ULTRALIGHTS**
**SINCE THEN, BRS HAS MOVED INTO EXPERIMENTAL AND GENERAL AVIATION AS WELL **
**OVER 18,000 SYSTEMS SOLD – 1500 GENERAL AVIATION AIRCRAFT**

## AN OVERVIEW

**HERE’S A TYPICAL ULTRALIGHT INSTALLATION**

## ULTRALIGHTS

**THIS IS A BRS CANISTER SYSTEM INSTALLED ON THE UNDERSIDE OF AN ULTRALIGHT**

## GENERAL AVIATION

**IN 1998, CIRRUS DESIGN OF DULUTH, MINNESOTA BEGAN PRODUCTION OF THE SR20 SINGLE ENGINE, 4-PLACE, COMPOSITE AIRCRAFT, WHICH WAS SOON FOLLOWED BY THE SR22. EACH CONTAINS A BRS PARACHUTE SYSTEM**

## CIRRUS CALLS IT “CAPS”, OR:
    CIRRUS AIRFRAME PARACHUTE SYSTEM

**CIRRUS CALLS IT *****“CAPS”,***** OR:**
**    ****CIRRUS AIRFRAME PARACHUTE SYSTEM**

## CIRRUS DESIGN

**THE PARACHUTE IS INSTALLED BEHIND THE BAGGAGE AREA. ALSO VISIBLE HERE IS THE ROCKET MOTOR IGNITER**

##  CIRRUS DESIGN

##  CIRRUS DESIGN

**UNFORTUNATELY, THE CIRRUS ACTIVATION CABLE IS COMPLETELY COVERED. ONE LIKELY ACCESS POINT IS ADJACENT TO THE BAGGAGE DOOR, UNDER THE HEADLINER**

## CESSNA 172

**IN 2002, BRS RECEIVED A SUPPLEMENTAL TYPE CERTIFICATE (STC) FOR A C172 PARACHUTE SYSTEM**

## CESSNA 172

**THE CESSNA SYTEM IS MOUNTED IN THE BAGGAGE COMPARTMENT AND IS EXTRACTED THROUGH THE REAR WINDOW**

## CESSNA 172

## CESSNA 182

**IN MID-2004, BRS RECEIVED AN STC FOR THE C182 SYSTEM**

## CESSNA 182

**SHOWN DURING INSTALLATION, THIS IS THE PARACHUTE CANISTER AND ROCKET  HOUSING**

## CESSNA 182

**THE ACTIVATION CABLE CAN BE ACCESSED THROUGH THE BAGGAGE DOOR AND BEHIND THE PARACHUTE CANISTER**

## CESSNA 182

**THIS SHOWS THE IGNITER AT THE BASE OF THE ROCKET MOUNT. THE ACTIVATION CABLE EXTENDS DOWNWARD TO THE FLOOR PAN, THEN FWD TO THE HANDLE BOX**

## CESSNA 150

**IN THE EARLY 90’S, BRS RECEIVED AN STC FOR THE CESSNA 150/152 MODELS. NOT A GREAT NUMBER OF THESE SYSTEMS WERE FIELDED**

## CESSNA 150

**THE C150 SYSTEM IS INSTALLED INTO THE ROOF OF THE BAGGAGE AREA. THE ROCKET IS INSIDE THIS CONTAINER.**

## CESSNA 150

**CESSNA 150**

## INITIATING THE SYSTEM

**ALL BRS PARACHUTE SYSTEMS ARE EXTRACTED AND DEPLOYED THROUGH THE USE OF A SOLID PROPELLENT ROCKET MOTOR, WHICH USES A HIGHLY SAFE AND RELIABLE MECHANICAL IGNITER**
**THE IGNITER IS CONNECTED VIA ***CABLE*** TO THE ACTIVATION HANDLE**

## ACTIVATION ASSEMBLY

## IGNITER ASSEMBLY

**THE BRS MECHANICAL IGNITER ****DOES NOT USE STORED ENERGY****. THE SPRING IS *****NOT***** COMPRESSED PRIOR TO THE ACTIVATION SEQUENCE**

## IGNITER INTERNALS

## Slide 24

## BRS 600/900 MOTORS

**USED ON GENERAL AVIATION OR**
**    ****HEAVIER SPORT AIRCRAFT**

## BRS 300/400 SERIESROCKET MOTOR

**USED ON ULTRALIGHT AIRCRAFT**

## SPORT SYSTEM LAUNCH TUBE

** ****OFTEN ATTACHED DIRECTLY TO THE PARACHUTE BOX OR CANISTER**

## OLD “ISP” MOTOR

**FOUND ONLY ON PRE-1998 ULTRALIGHT AIRCRAFT**

## DROGUE GUN

**OBSOLETED**
**    ****IN 1988**

**THE DROGUE GUN USED A PROPELLANT CHARGE TO FIRE A HEAVY STEEL WEIGHT. KINETIC ENERGY PULLED THE PARACHUTE OUT**

## LARGE BRS MOTOR IN LAUNCH TUBE

**AS FOUND ON CIRRUS, CESSNA**
**   ****AND LARGE SPORT AIRCRAFT**

## BRS CANISTER MODELWITH LAUNCH TUBE

## BRS SOFT PACK MODEL

## VERTICAL LAUNCH SYSTEM(VLS)

## THE CORE ISSUE:

**AN AIRCRAFT HAS CRASHED, WHICH OFTEN RESULTS IN THE ROCKET FIRING UPON IMPACT. HOWEVER, IN CERTAIN INSTANCES, THIS DOES NOT HAPPEN, LEAVING A LIVE ROCKET, ATTACHED TO THE ACTUATING CABLE, IN THE MIDST OF A TWISTED WRECKAGE.**

## CIRRUS SR20/22

## THE PREFERRED ALTERNATIVE:

**    ****FIRST SUCCESSFUL USE OF THE “CAPS” SYSTEM BY A CIRRUS PILOT, LIONEL MORRISON, OCTOBER 2002**

## N116CD – IMPACT WITH TERRAIN

## PARACHUTE AND ROCKET

## Slide 39

## RECOGNITION

**WHEN YOU ARRIVE AT AN ACCIDENT SCENE AND CIRCUMSTANCES ALLOW YOU TO APPROACH THE WRECKAGE, LOOK FOR ANY OF THE THREE MAJOR BRS SYSTEM COMPONENTS:**

**PARACHUTE PACK**
**ROCKET**
**ACTIVATION HANDLE**

## CLEAR AN AREA

**ONE OF THE STICKERS ON THE LAUNCH TUBE ADVISES ****“TREAT LIKE A LOADED GUN”****. WITH THAT IN MIND, CLEAR A 90 DEGREE AREA LYING IN THE PATH OF THE ROCKET, EXTENDING 100 FEET OUT, IF POSSIBLE**

## ASCERTAIN:

**DETERMINE WHETHER OR NOT THE CRASH HAS CAUSED THE ROCKET TO FIRE. TYPICALLY, YOU WILL SEE THAT THE PARACHUTE HAS BEEN PULLED FROM ITS CONTAINER. **
**IN VIOLENT CRASHES, IT IS VERY COMMON FOR THE ROCKET TO HAVE FIRED. **

## WHY DOES THE ROCKET FIRE DURING IMPACT?

**DURING A VIOLENT CRASH, THE AIRFRAME SUBSTANTIALLY DEFORMS OR IS OTHERWISE DESTROYED.  AS A RESULT, THE CABLE JOINING THE ROCKET MOTOR TO THE HANDLE IS STRETCHED TO THE POINT THAT THE IGNITER IS FUNCTIONED AND THE ROCKET FIRES.**

## ROCKET HAS NOT FIRED

**YOU’VE DETERMINED THAT THE ROCKET HAS NOT FIRED. THEN...**
**DETERMINE THAT THE ACTUATING CABLE IS NOT STRETCHED TIGHTLY BETWEEN THE ROCKET AND THE HANDLE. THIS IS EXTREMELY UNLIKELY, BUT COULD PRESENT A SITUATION IN WHICH THE IGNITER IS ON THE BRINK OF BEING FIRED.**

## REPLACING THE SAFETY PIN

**LOCATE THE ACTIVATION HANDLE**

**PLACE A 3/16” DIA. PIN INTO THE SAFETY PIN HOLE**

## SAFING PROCEDURE

**YOU CAN NOW PROCEED TO DO**
**ONE OF TWO THINGS:**
**DISCONNECT THE CABLE FROM THE IGNITER, OR **
**CUT THE CABLE ITSELF USING A SUITABLE TOOL.**

## DISCONNECT CABLE

**REMOVE THE CAP PLUG THAT HIDES THE ATTACHING SCREW**
**USING A 1/8 INCH ALLEN KEY, REMOVE THE MACHINE SCREW THAT SECURES THE CABLE TO THE IGNITER**

## CABLE TO IGNITER ATTACHMENT

## CABLE TO IGNITER ATTACHMENT

## SEVER THE CABLE

**IN A CIRRUS OR CESSNA, THIS IS OFTEN THE MOST STRAIGHT- FORWARD METHOD. EXPOSE A SECTION OF THE ACTIVATION CABLE, PREFERABLY NEAR THE ROCKET AND CUT IT WITH A SUITABLE TOOL SUCH AS A FELCO CUTTER**

## THE FELCO CUTTER

**THIS IS THE SMALLER FELCO CUTTER – THEY MAKE SEVERAL SIZES, AS DOES THE GREENLEE TOOL COMPANY, DIVISION OF TEXTRON**

## ALTERNATE  APPROACH:

**SOME AGENCIES HAVE TAKEN THE POSITION THAT DEACTIVATING A BRS SYSTEM IS BEST LEFT TO EXPERTS AND THEREFORE RECOMMEND CONTACTING THE LOCAL BOMB SQUAD. WE LEAVE THIS DECISION UP TO THE AUTHORITIES IN CHARGE AT THE SCENE OF AN ACCIDENT**

## DISPOSAL OF ROCKET

**THE SMALLER ULTRALIGHT MOTOR IS RELATIVELY EASY AND SAFE TO DISPOSE OF. UPON REQUEST, BRS WILL PROVIDE THE NECESSARY INFORMATION.**
**THE LARGER GENERAL AVIATION ROCKET MUST BE HANDLED IN A MORE EXACTING MANNER. CONTACT BRS FOR INFORMATION**

## IN CLOSING

**A PRIMARY CONSIDERATION IN THE DESIGN OF BRS SYSTEMS IS ****SAFETY****. BY BEING OBSERVANT AND EXERCISING CAUTION IN DEALING WITH AN UN-ACTIVATED SYSTEM, THE CHANCES OF AN INADVERTENT FIRING ARE ALMOST NIL. HOWEVER, SHOULD YOU ENCOUNTER THIS SITUATION, DO NOT HESITATE TO CONTACT BRS FOR ADDITIONAL INFORMATION. THANK YOU.**
