SEA RESCUE EQUIPMENT FOR AIRPLANE CREWS

e [Music] tough luck pilot but don't worry about a dunan you'll be back on the surface Pronto and that's where you'll get a welcome assist from a real pal your life vest and a pretty Dependable pal with that because here in the parachute equipment room we sought an anticipate an emergency like yours yes even though Flyers make their own pre-flight checkups it's our job to double check with regular inspections of our own how do we do it just relax and we'll show you every 6 months that vest of yours gets a complete inspection whether you have used it or not to begin with we open the mouth valve and blow up the two compartments as hard as we can we never use an air hose though it might bust the scenes we could use the CO2 equipment on the vest itself providing there are plenty of replacement cartridges don't forget that we never use CO2 cartridges unless we've got plenty on hand after both compartments are inflated the vest is tested underwater like an ordinary tire tube any leaks uh-oh there she blows if there are Replacements in stock it's better to condemn any leaky vest and turn it in for second outage but if not and that's often the case dry the vest and Mark it for repair we never vulcanize a patch on a life vest why well that's easy to explain it's made of a single shell of rubberized fabric oh it's sturdy enough to take plenty of punishment and rough water but the rubber on the inside where the Vulcanizing machine can't reach it so we apply a cold patch we remember when cleaning and brushing not to use any pressure on the damaged area another important warning at this stage is to avoid the use of any oily or aromatic cleaning solvents that might injure the fabric after the damaged area is cleaned and brushed we apply cement one coat spread it around and give it a chance to dry two coats spread that around and wait 10 minutes three coats some more spreading some more drying and finally the patch itself and we make it stick we know how tough it is for a flyer to be floating around in the ocean with nothing but a mile of more Ocean between him and the bottom so plenty of care goes into that patch right up to the talcum powder that finishes the job still not satisfied however we inflate the newly repaired compartment once more then back it goes to the dunking department just to make sure you can bet your buddy's last buck there are no bubbl now having made sure of that we wipe off the vest again open the valves and deflate when we're sure it's empty of all air we close the mouth valves and give the vest another visual inspection not only the fabric itself but all of the gadgets as well we've got to be sure the discharge mechanism Works freely and easily there are two CO2 cylinders that have to be checked with every test so we unscrew a chamber and take out the CO2 cartridge we make sure the cartridge is intact by examining the tip to see that it hasn't been punctured well we know now that one CO2 cylinder is in perfect working condition but we don't take anything for granted so we turn the vest over and repeat the same inspection on the other cylinder and that's that except for stenciling the date of inspection the job on the life vest is complete now let's see about the oneman life raft first we open the pack and take out the raft and accessories we handle this and all C rescue equipment carefully banging it around now cause it to fail when some flyer really needs it we make sure the snap Fasteners are in good working order and examine the pack covering carefully for traces of oil or acid now we remove the raft itself from the pack and unfold it this is a good time to make a preliminary note of any chased or worn places along the fold it's all right to use an air hose or a pump to inflate this raft we attach it to the mattress valve open the valve and let her go the the mattress valve is closed tightly before we detach the air hose the pressure is now taken with a Mercury monometer by the way if a Mercury monometer isn't available we could rig up a sensitive gauge out of a fuel pressure indicator but we never use any Hasty substitute like an ordinary tire gauge it just wouldn't be accurate enough the pressure must be 2 lb per square in now we note the time and in an hour check the pressure again if it is varied at all we bring it back to the 2 lbs per square in pressure this time we leave the raft inflated for 24 hours then the pressure is measured again if it has fallen to less than a pound we disconnect the monometer and go hunting for leaks using the good old soapy water method if any leaks are to be found we find Sherlock Holmes is a at hunting Clues compared to us we cover every inch of the raft surface ready to Mark any and all Telltale soap bubbles for later repair uhoh see what I mean if the damage is serious the raft is condemned for Salvage if it's minor however we Mark the Spot and go back to patchet after finishing our inspection like the life vest the oneman rft calls for a cold patch we make sure the surface is clean before applying the three coats of cement having finished our patch we turn to the CO2 unit leakage is checked here by removing the cylinder and weighing it on a sensitive scale if it shows a loss of weight beyond the content specified in its marking we can demem it and replace it with a fresh one but this one's okay so we check the lock pin to see that it slides easily and is well tied after that it's placed back in its container on the side of the ra here it will be securely laced after it is finally reconnected now for the accessories and we don't have to talk about how important they are in the accessories kit we should find emergency drinking water C marker then there's also a repair outfit consisting of a pair of scissors a roll of cold patch material a scraper to clean the damaged area and a bottle of cement we make sure it hasn't dried out after checking these pieces back they go into the repair kit but there are other accessories too Bullet Hole plugs two of them like this paddles and they better be two of those too sea anchor bailing cup each item present and accounted for and each item in perfect condition now we unscrew the mouth valve and deflate the raft all of the air must be removed for on high altitudes The increased pressure might cause any remaining air in the raft to expand so we use a deflation pump to make sure every bit of air is sucked out a flyer with a nip on his tail has enough to do without worrying about a raft blowing up under his pants when we are positive the raft is as empty as a Hitler promise the mouth valve is put back on and tightly closed powdering is the next step and I mean powdering like a baby after a bath covering all parts where chaping might rough up the skin now back go the accessories into their proper places and this is no time to leave any of them behind finally we're ready to fold the raft and here's an operation that has to be handled with a special care we're particular to smooth out the fabric as we go because unwelcome wrinkles might weaken the surface when the raft is packed the complete pack mustn't have any lumps or bulges it should fit as tightly as Garing into his air stot girdle the inspection record tag is initialed and dated and after the raft strap is check the inspection job is finished at least every 6 months all types of multiplace rfts are given a complete checkup this one is 1,000lb type after the accessories bag is removed the raft is inflated with compressed air again we could use the CO2 system of the raft itself but as we said before why use up the supply of cylinders unless you have to the pressure of the multiplace raft is also measured with the Mercury monometer we use the same pressure reading as in the Onan life R 2 lb per square in the raft is then left inflated for 6 hours perhaps a slow leak may show itself if there should be a drop of more than 10% in the pressure we would again hunt for the leak with soapy water on these big babies a Hot Patch is better providing equipment is available if not however a cold patch is adequate but according to the monometer this one didn't need any patch so our next move is to deflate the raft the manifold valve is now disconnected and inspected we examine every part of it minutely for dirt grease corrosion or mechanical defects if it is in the pink of condition back it goes each mattress valve is unscrewed and examined for the same kind of flaws if up to par it's reset we can't be too careful with these gadgets there's no guessing in this kind of work so much for the mattress valve now for the accessories which are just as important as the raft itself any one of these items May mean saving a Flyer's life there's the fishing kit with a knife and different kinds of tackle and bait everything a guy needs for a sure dinner now we check the cans of sea marker which are used to color the water so the raft can be spotted easily from the sky then there's your emergency drinking water and a reversible orange and blue waterproof cloth that can be used for a sail for camouflage a recognition flag a rain catcher or to prevent sunburn having seen that everything the to calls for is there we now to the CO2 cylinder itself we examine every part of it carefully again watching out particularly for dirt oil corrosion or defective parts and turning in the cylinder for replacement if it's faulty if everything checks however the cylinder is reinstalled and reconnected to the manifold after the wing nut is tightened both manifold and cylinder are tested for security now we hook up the deflation pump and remove all the remaining air from the raft after the raft has been well powdered the accessories are repacked that completes the six months inspection except for folding the raft and stowing it in its case the raft is now ready to be stored far away from light stoves radiators damp cellers or leaky sheds only where it is cool and dry the 100h hour inspection is the same for all sizes of multiplace rats let's take a th000 Pounder from a B7 and see what happens first the cover of the small compartment is unfastened then the release cable is disconnected and the cover of the WRA compartment is unlocked we are careful not to accidentally discharge the CO2 cylinder and the raft compartment while doing this the raft is then taken out and spread on the wing which makes it easy to UNS SC the release cable from the CO2 cylinder now the release cable is disconnected from the release lever of the cylinder the cable housing and cable are then replaced and temporarily attached in the compartment where they won't get lost damaged or needlessly exposed to any dust or dirt now the raft is brought to a repair shop or any sheltered spot one man begins to remove the CO2 cylinder while another verifies the inspection record tag Yep this baby's 100 hours are up so he sees to it that all ties holding accessory kits are made secure while his buddy carries the CO2 cylinder to the scale to be weighed if it registers a loss of more than 3100s of a pound it is replaced with a fresh cylinder the cylinder will also be repl plac if it has been exposed to seawater however this cylinder is okay so back to the raft it goes meanwhile the other man examines all tags Corners edges and seen perhaps there may have been chasing next he sees to it that each of the mattress valves is tightly closed every one of them the CO2 cylinder is returned and reconnected to the manifold meanwhile the raft is getting a good powdering the wing nut is screwed to the manifold and the coupling made secure it takes a lot of powder to cover this rubber hippopotamus especially when you have to spread it around so but that's about all there is to the 100h hour inspection of the multiplace raft the only remaining touch now is to replace the raft in its compartment on the plane once more the raft is spread out on the wing careful not to lose any powder the release cable is taken from the compartment to be reconnected to the CO2 cylinder first the coupling is put on then the release cable is joined to the release lever of the cylinder the little Gadget is tricky so we make sure it's hooked and locked next the housing is connected and made fast with a wrench after that we're ready to put the wraft back in the airplane to do that little job we lift the cylinder end of the raft into the raft compartment then move over to the small compartment to reset the lock and connect the free end of the release cable to the pull cable now we lay the remain of the raft into the raft compartment fold by fold and then fasten the cover tightly finally the inspection record tag is initialed and the cover of the small compartment is secure well that gives you an idea of how we do our job but there's one thing more we know how you Flyers depend on us to keep your sea rescue equipment in good shape we want you to know that we're always in their punching we just won't gamble on your f [Music]
