Tag: Keep an Eye Out, March 2011

Although this jumper received a pin check a few minutes prior to exiting, his pin came loose prematurely, and he opened in a head-down position about six seconds after leaving the plane. Fortunately, he and the other jumper were unhurt by the premature deployment. more »

Why You Shouldn’t Leave Your Rig in the Trunk of Your Car

Tag: Keep an Eye Out, January 2011

A jumper left his rig in the trunk of his car for a few months before giving it to his rigger for a reserve repack. During the inspection, the rigger discovered that a stow band had melted to the grommet on the main deployment bag. As the photo shows, it took quite a bit force to break the stow band and allow the deployment bag to open fully. The melted stow band was a black rubber band from an unknown source. There have been similar cases reported in the past of black rubber bands melting and sticking to grommets or even disintegrating into small pieces. This may be caused by a chemical reaction between the rubber band and grommet or by the heat generated in the trunk of a car. more »

I want to buy a used rig from an internet site, but I’m not sure it will fit. How can I find out before I ask the seller to ship it, and can the size of the harness be adjusted? more »

Choosing the Correct Canopies for Your Students

Tag: The Rating Corner, January 2011

There are many variables to consider when deciding what size canopy a student should jump. Years ago, this was not really an issue—every student jumped a 300-square-foot canopy, and instructors didn’t need to make a choice. But while larger canopies allowed for soft landings (at least in most cases), the very low wing loadings meant that even the slightest amount of wind caused students to fly backward. In those days, it was not unusual for students to back into trees, power lines or other landing hazards. more »

Hypoxia: Impending Judgment on Reaction Times

Tag: Safety Check, January 2011

The Federal Aviation Regulations (FARs) set the requirements for the use of oxygen while on aircraft in Section 91.211 of the FAA’s General Operating and Flight Rules. The section applies to pilots and passengers, including skydivers, even though there is no mention of oxygen use in the more familiar Part 105, Parachute Operations. Jump pilots are required to use supplemental oxygen above 14,000 feet mean sea level (MSL), and supplemental oxygen must be provided to each skydiver when the aircraft is above 15,000 feet MSL. The USPA Basic Safety Requirements also mandate the use of supplemental oxygen for skydives above 15,000 feet MSL. more »

Loose Brake Line and Locked Toggles

Tag: Keep an Eye Out, December 2010

When excess steering line came loose from the keepers on one of a jumper’s risers during an otherwise-normal deployment, he inadvertently reached through the loop of excess line when he grabbed his toggle to release his brakes. When he pulled the toggle, it locked the steering line to the riser as shown in the photo. When he discovered that he could not steer or flare his canopy well, the jumper cut away and landed safely under his reserve. Jumpers should use caution when packing to make sure they stow the excess steering line securely. They should also make sure that their toggles are clear of any excess steering line when they release their brakes. more »

Closing the Gap

Tag: The Rating Corner, December 2010

A jumper who recently received a USPA A license stated that he wished he had learned the functions of the front and rear risers in detail, how to avoid canopy collisions, the appropriate times to disconnect a reserve static line (RSL), the best way to get back to the airport from a long spot and how he should flare his canopy during low-wind landings. If his instructors had trained this jumper properly, wouldn’t he already know this stuff? Yet somehow, his instructors still signed him off to receive his USPA A license. It is sad that some drop zones continue to provide student training that leaves so many gaps in skills and knowledge. more »
