Presentation Transcript

  1. 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

  2. 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

  3. AN OVERVIEW • HERE’S A TYPICAL ULTRALIGHT INSTALLATION

  4. ULTRALIGHTS • THIS IS A BRS CANISTER SYSTEM INSTALLED ON THE UNDERSIDE OF AN ULTRALIGHT

  5. 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

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

  7. CIRRUS DESIGN • THE PARACHUTE IS INSTALLED BEHIND THE BAGGAGE AREA. ALSO VISIBLE HERE IS THE ROCKET MOTOR IGNITER

  8. CIRRUS DESIGN

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

  10. CESSNA 172 • IN 2002, BRS RECEIVED A SUPPLEMENTAL TYPE CERTIFICATE (STC) FOR A C172 PARACHUTE SYSTEM

  11. CESSNA 172 • THE CESSNA SYTEM IS MOUNTED IN THE BAGGAGE COMPARTMENT AND IS EXTRACTED THROUGH THE REAR WINDOW

  12. CESSNA 172

  13. CESSNA 182 • IN MID-2004, BRS RECEIVED AN STC FOR THE C182 SYSTEM

  14. CESSNA 182 • SHOWN DURING INSTALLATION, THIS IS THE PARACHUTE CANISTER AND ROCKET HOUSING

  15. CESSNA 182 • THE ACTIVATION CABLE CAN BE ACCESSED THROUGH THE BAGGAGE DOOR AND BEHIND THE PARACHUTE CANISTER

  16. 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

  17. 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

  18. CESSNA 150 • THE C150 SYSTEM IS INSTALLED INTO THE ROOF OF THE BAGGAGE AREA. THE ROCKET IS INSIDE THIS CONTAINER.

  19. CESSNA 150

  20. 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

  21. ACTIVATION ASSEMBLY

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

  23. IGNITER INTERNALS

  24. BRS 600/900 MOTORS • USED ON GENERAL AVIATION OR HEAVIER SPORT AIRCRAFT

  25. BRS 300/400 SERIESROCKET MOTOR • USED ON ULTRALIGHT AIRCRAFT

  26. SPORT SYSTEM LAUNCH TUBE OFTEN ATTACHED DIRECTLY TO THE PARACHUTE BOX OR CANISTER

  27. OLD “ISP” MOTOR • FOUND ONLY ON PRE-1998 ULTRALIGHT AIRCRAFT

  28. DROGUE GUN • OBSOLETED IN 1988 • THE DROGUE GUN USED A PROPELLANT CHARGE TO FIRE A HEAVY STEEL WEIGHT. KINETIC ENERGY PULLED THE PARACHUTE OUT

  29. LARGE BRS MOTOR IN LAUNCH TUBE • AS FOUND ON CIRRUS, CESSNA AND LARGE SPORT AIRCRAFT

  30. BRS CANISTER MODELWITH LAUNCH TUBE

  31. BRS SOFT PACK MODEL

  32. VERTICAL LAUNCH SYSTEM(VLS)

  33. 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.

  34. CIRRUS SR20/22

  35. THE PREFERRED ALTERNATIVE: FIRST SUCCESSFUL USE OF THE “CAPS” SYSTEM BY A CIRRUS PILOT, LIONEL MORRISON, OCTOBER 2002

  36. N116CD – IMPACT WITH TERRAIN

  37. PARACHUTE AND ROCKET

  38. 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 RECOGNITION

  39. 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

  40. 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.

  41. 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.

  42. 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.

  43. REPLACING THE SAFETY PIN • LOCATE THE ACTIVATION HANDLE • PLACE A 3/16” DIA. PIN INTO THE SAFETY PIN HOLE

  44. 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.

  45. 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

  46. CABLE TO IGNITER ATTACHMENT

  47. CABLE TO IGNITER ATTACHMENT

  48. 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
