    Expired cypres in a riggers rig

    Are you sure? I've never heard of lithium battery doing that. Just older chemistry ones. ------------------------------------------------------------------- I have seen one Cypres 1 battery short-circuit and over-heat. I detected the unusual temperature when I touched the bottom wall. I quickly removed the Cypres, removed the battery and sent the AAD back to SSK. Fortunately, I reacted quick enough to prevent long-term damage to AAD, canopy or container.

    Expired cypres in a riggers rig

    First time I have heard that rumour. But I have only been jumping for 40 years and rigging for 33 years. Do you remember the biblical story about Jesus Christ encountered a crowd stoning an adulteress? Jesus stepped into the fray and said:"Let he who is without sin throw the first stone." "A boulder the-size-of-a-watermelon sailed over the crowd, crushing the accused's skull." Jesus looked to the back of the crowd. "Mom! Some days you can be a real bitch!" Hah! Hah! Responding seriously to the OP's question: when Airtec was testing Cypres 1 prototypes, they subjected them to thousands of hot and old cycles. Eventually they determined that soldered joints might fail after 12 years of hard use. These tests are standard for a wide variety of aerospace components. Engineers try to imagine the most rugged service life ..... Try to picture a flying school with student pilots landing hard dozens of times per day. Then engineers simulate that abuse in a lab. Once they have determined how long a component with last in rough service, they delete the last 30% and set that as the maximum service life. MSL might be defined by years ..... number of landings ..... hot-cold cycles ..... corrosion ..... etc. MSL is at best an educated guess by knowledgeable engineers.

    Expired cypres in a riggers rig

    Agreeing with councilman ...... If you mailed a Cypres 1 (or most Cypres 2 production) back to the factory after its 12th birthday, Airtec staff would have a good laugh and offer you a discount on a new Cypres. In 2032, if you mail a 2017-made Cypres to Airtec or SSK, they will have a good laugh and offer you a discount on a new Cypres. Bottom line, no factory will: inspect, assemble, repair, modify, alter, update or pack any parachute component after its planned retirement. Retirement schedule is written in the manual.
  4. Glad to hear that the vote was postponed. As a Canadian pilot and skydiver, I was ambivilant about ATC privatization until a couple of years ago. Over the last two years an-overly-ambitious airport manager and under-ambitious air traffic controllers (Nav Canada) limited skydiving at Pitt Meadows Airport (CYPK) so many times that they could not pay their bills. Many sunny Sundays (over the last two summers) saw zero parachutes over Pitt Meadows! That DZO closed forever on Sunday, 2017, September 23. Skydivers had been jumping at Pitt Meadows on-and-off for the last half century. Pilot Donn Richardson has shared some his experiences flying jumpers back during the 1960s. Yes, I was honoured to be invited on the last load at Pitt Meadows ........ but it was one of those honours that stirs up sad thoughts ..... like being invited on an ash dive! In conclusion: Americans are wise to resist privatized ATC because privatized ATC will routinely deny clearance to jump-planes, forcing DZs out of business.

    Expired cypres in a riggers rig

    ----------------------------------------------------------------------- Holy thread diversion our dear skytribe!!!!!!! You are the first person to mention "warranty"during a debate on AADs! Warranty only relates to repairing manufacturing defects during the first few months after it left the factory. NO parachute component is warrantied to save your sorry ass! Even with the best manufactured, assembled and packed parachutes will not keep you alive if you make too many mistakes. All the early Cypres retire after 12.5 years. Only Cypres 2 - made this year - will be factory-maintained by Airtec and only before their 15.5 year retirement date.

    I did my first cutaway and it feels bad

    Congratulations! You made a mistake. You responded correctly You did not tear up your parachute You did not injure yourself You learned a lesson You shared your learning experience with other skydivers That makes you a better skydiver than most Convratulate yourself!

    I did my first cutaway and it feels bad

    That "only a single jump-run" policy may have been imposed by lazy air traffic controllers. Bad attitude because it increases everyones' stress levels and malfunction rates. Professional DZOs don't whine about the few extra dollars worth of gasoline because they understand the alternative.

    world record for highest tandem jump?

    Ask Steve Noonan about his exit altitude MSL when he tandem jumped near Mount Everest. I suspect that some military tandems have jumped from higher, but they are not the sort to brag .....

    Most athletic skydiving discipline?

    ....... Dozens of tandems: Is it the stress that deployment puts on the body with all that weight? Or steering the toggles? I've noticed on tandems that the toggles seem "heavier" when I try to steer than when I'm flying my own canopy. -------------------------------------------------------------------- All of the above ..... plus carrying a 50 pound rig, plus carrying 200 pound students out of the airplane, plus all of the psychology of couxing first-timers out of the airplane, maintaining professional decorum even when you are exhausted, plus ..........

    Most athletic skydiving discipline?

    A dozen tandems a day challenges Many muscle groups, endurance, situational awareness, balance, coordination, etc.

    opening door during flight

    Returning to the OP ...... COOLING is the primary reason for opening the door during climb. Comfort ..... This is a " First World" problem .... that pales in comparison with staying alive ..... flying the airplane, etc.

    Victoria vs Vancouver?

    Yes, they are searching for an alternate airstrip, but it will take a couple of years gather all the resources needed to operate a DZ. I overheard some negotiations, but it is way too early to say anything publically.

    Victoria vs Vancouver?

    Sorry if I got you all excited about Pitt Meadows. I only heard the bad news Saturday evening. Pitt Meadows is closed for the season and for the next few years. People have jumped at Pitt Meadows since the 1960s, but the last couple of years have been too slow because of uncooperative ATC and runway upgrades. They simply could not fly enough days to earn a living. Sunday evening, the sunset load included 10 belly-fliers trying to build a formation.

    Victoria vs Vancouver?

    Today I did 5 tandems at Victoria Skydivers. My best day I did 8. My best day at Pitt Meadows included 14 tandems. Sport jumpers can match those numbers if they pack quickly and consistently meet the plane when it lands. For 10 a day, you will need to jump at the bigger "resort" DZs that fly multiple Twin Otters .... none in Canada. Also consider that the jumping season in Canada is half as long as Perris. Pitt Meadows hosted their year-end BBQ today and most Canadian DZs close between Halloween and Easter.

    Victoria vs Vancouver?

    Both major cities each have their own pair of dropzones. Victoria is served by Capital City Skydivers and Victoria Skydivers. Both schools fly their Cessna 182s from Victoria International Airport and land I farm fields to the south. On a clear day you can see the Gulf Islands, Olympic Penninsula and Mount Rainier from 10,000 feet. Then you enjoy a 20 minute van ride back to the airport. Both offer tandem, IAD and gradual freefall training. Good vibes at both DZs 'cus they share many of the same fun jumpers. If Saturday dawns sunny, I will go do tandems for Victoria Skydivers. The big city: Vancouver is also served by a pair of DZs, but they are much farther from the city centre. Pitt Meadows always jumps in controlled airspace to avoid heavy jet traffic headed for Vancouver International Airport. Abby jump-pilots chat with ATC at Abbottsford Municipal Airport. Both DZs routinely climb to 12,000 feet .... maybe more if ATC is in a good mood. Vancouver Skydivers are closest to downtown Vancouver , at Pitt Meadows Airport. You can ride public transit (Skytrain and bus) to within 2 kilometres of Pitt Meadows Airport. Their airlift varies from Cessnas to King Airs. The last couple of seasons they have flown a shiny Navajo. PM's year end BBQ is this Saturday (2017 Sept 23). I may be biased towards Pitt because I worked there full-time for 11 years. The other Vancouver DZ is even farther out at Abbotsford ..... almost to the Mission Bridge! They run a shuttle van from downtown Van' but that is mainly for tandem students. Airlift includes a Porter, a Kodiak and a flock of single-engined Cessnas. Much more partying at Abby. If you are trying to choose between UVic and UBC confided other factors like cost of living. Vancouver housing is frightfully expensive within 2 hours commute from the campus.

    Raven1 reserve - What size?

    If you hang more than 180 pounds under a Raven 1, you are "a stupid, fat white man." That is because Ravens were designed long before any one was building canopies designed for wing-loadings more than 1 pound per square foot. Why anyone would expect a Raven to land softly at more than 1 pound per square foot is ..... um ..... er ...... optimistic ...... clueless ....... over confident .......
  17. She ENJOYS cleaning? She clearly does not have enough to keep her mind occupied. OTOH most dogs think that vacuum cleaners are the spawn of Satan, while cats instinctively flee from those evil, cat-swallowing machines. On a related note: many years ago I was visiting family in Denmark. I phoned the local jump club to see if I could sneak in a jump. Later, I mentioned to my uncle that the club was opening a DZ near Roskilde .... quiet town surrounded by farms. My uncle replied: "They are going to have problems with mopeds." "What?" The he explained Denmark's graduated drivers' licences and how teenagers were only allowed to drive mopeds for the first few years. Teenaged boys being teenaged boys ...... some of them "modified" moped mufflers to go faster.

    Rapide link vs Slink on bridle connection

    Maillot Rapide link barrels create an extra wear point that frays your bridle. OTOH soft links eliminate one wear point.

    opening door during flight

    Refer to hackish's last post. Some planes fly miserably with a door open. Other operating handbooks (single-engine Cessnas) say to unlatch the door and push it slightly open before a forced landing. Both options are best discussed with your jump-pilot long before a forced landing. Maybe this should be a topic during SAFETY DAY in the spring??? As for the risk of being trapped in burning wreckage .... A: Few jump-planes are destroyed by fire (see Annette O'Neil's series of articles from a year ago) .... B: I would rather be awake for the fire, belted into my seat, etc.

    opening door during flight

    To clarify: risks of opening doors in flight varies radically with the type of door. 1. Cessna top-hinged 2. Sliding external side door 3. Slide up internal door 4. Tail ramp 1. Cessna top-hinged door is only available as a Supplementary Type Certificate. STCs include airspeed limits and whether the pilot must wear a pilot emergency parachute (normal). Typically the pilot slows the airplane, yells "DOOR" and twists a handle to unlock the door. Then he/she does the secret dance-on-rudder-pedals to prevent the door from slamming against the underside of the wing. If the Cessna makes multiple passes (e.g. Static-line students) the pilot usually closes the door between passes. The pilot definitely closes the door before descending. The greatest risk is if a pilot huge gets loose when the door is open. The preferred response involves diving after the offending pilot-chute. If the chute inflates before you exit, it will try to drag you THROUGH the door frame ..... around ..... through. Since most Cessnas have control cables and fuel lines hidden in door frames, things can get real messy .... real fast! A few Cessnas have gotten lucky (?) and landed under fully-inflated round canopies ...... not the recommended configuration. The other risk is hitting the horizontal tail during a pre-mature deployment. 2. Sliding external door (Airvan, Porter and many helicopters. Only opened when the pilot tells you to. Sometimes the pilot signals "door open" with pretty coloured lights. The best airplanes have labels beside lights. Second best is briefing every jumper who sits beside the door. Some external sliding doors can be closed by the pilot ..... if not, the pilot needs to limit airspeed during descent. Risks are similar to above. 3. Slide-up internal doors are popular on airplanes with the side cargo door aft of the wing: Cessna U206 & 208 and most light twins. Jumpers still need approval from the pilot before opening the door (see above about signal lights). Since SUID are the easiest to open in flight, some DZs allow jumpers to open doors a bit between 1500' and 5000'. Most insist that all seat-belts be disconnected before opening the door. Smart jumpers pat their handles and glance at their buddies' rigs before opening the door. This allows cool air into the cabin on hot, muggy summer days. Above 5000' all doors should be closed while tandems connect students, pin-checks, etc. Even if jumpers near the door don't hear it, some open doors create nasty air turbulence in the cockpit making it impossible for pilots to hear air traffic controllers. Risks are as above. 4. Tail ramps are the most fun to jump because you can stand upright ... like a Neanderthal .... Er ..... Um ..... you get the joke? Opening ramps too early is scary because it feels like you might slide out of the airplane/helicopter without seatbelts. Tail ramps are normally left closed until the start of jump-run. They are usually only opened by specially-trained staff members. Ramps on large (20+ jumpers) military aircraft are opened and closed - hydraulically - by the crew. Ramps prose T the lowest risk if a parachute deploys pre-maturely. The hapless parachutist disappears out the back!
  22. ........ About the only way I know is to comb through the old local newspapers from the time to find if it's mentioned. ........ ------------------------------------------------------------ Fortunately for Canadians, Mr. Molson did all that research and his book includes sources .... like local newspapers. He documents dozens of exhibition jumps - from hot air balloons - during the late 1800s. Most of those jumps were done to entertain crowds at county fairs. He also documents a few exhibition jumps from rickety early biplanes early in the 20th century, but exhibition jumping didn't really take off until after World War 1 when hundreds of military pilots returned to Canada and military-surplus airplanes (e.g. Curtis JN-4 Jenny trainers) were sold at auction for a song. The 1920s were the heyday of barnstormer a working county fairs etc.

    Unsupportive people/downers/scare-bears

    Agreeing with pterodactyl!1986 How they challenge their youths is a measure of the maturity of a society. All teenagers want to challenge themselves physically and mentally to prove that they are capable of the greater challenges in life. Back in cave-man days, chasing a pack of wolves off a deer carcass might mean the difference between starvation or survival. Modern society - with steady food supplies - presents fewer live-or-die challenges ..... so societies invent other challenges: cattle rustling, warfare, exploration, mountain climbing, deep sea diving, barroom brawling, marathon running, skydiving, etc. Skydiving offers a rare opportunity to scare your self to death but still have a reasonable chance of survival .... IF ..... you follow the plan. Whenever I hear that old saw: "Why would you want to jump out of a perfectly serviceable airplane?" I rely: "You haven't seen our airplanes!" If they persist in their obnoxious ... I offer them a long, painful, bloody story about my last ride in a particular King Air. If they doubt my story, I point them towards the wreckage laying in the middle of Pitt Meadows Airport. If whuffos switch to asking "Do you have a death wise?" I reply 'Yup! But I must be the clumsiest suicide in history becasue I have failed more than 6,000 attempts."

    Strong Release System Failure.

    Hee! Hee! Your comment reminds me of a DZO who offered junior packers $5 to do 25-jump inspections. None of the riggers showed any interest for those wages. .... considering that a 25-jump inspection takes me at least of couple of hours on a Dual Hawk .... and by the time I have re-sew a few popped stitches .... I have been at it for half a day.

    Rigger Study Materials

    The FAA Parachute Riggers' Manual is the best English-language book. Strong's "25 Jump Inspection" Manual (Dual Hawk Tandem) is excellent for teaching inspections. Also tell them to start copying manuals for all the gear that is popular on their DZ. To that end, I usually start a rigging course by asking students to name popular gear on their DZs, then tailor the course to match the gear they are most likely to work on. Following that same logic, I start the lecture on AADs by asking which AADs are most popular at their home DZs. If apprentices only mention modern electronic AADs, then I teach Cypres-centric course with brief mentions about how Vigil differs. More often, I assign a student to research a technical question and report back to the class tomorrow morning. The Australian Parachute Federation's master list of Service Bulletins, Airworthiness Directives, Technical Bulletins, etc. is the best single source for post-production fixes. French-speaking apprentice riggers should start with Eric Fradet's book: "Materiel d'au jour d'iu" (sp?).
