2339 прыжков
25 прыжков в вингсьюте, из них 15 прыжков в Vampire 3 (:facepalm: Vampire 3 требует 150 прыжков минимум в вингсьютах меньшей площади)
ОП Crossfire 135 WL 1.45
Шлем с левым расположением бокса (cx100) + с левой стороны смонтирована GoPro

Прыжок в вингсьюте 3way (59 сек с 4000м:-k), открытие, закрутка, отцепка ОП, RSL выдергивает шпильку ЗП, ЗП в работу не вступил, наблюдатели видели толко медузу над парашютистом. Стреньга ЗП вступила в конфликт с боксом видеокамеры или GoPro, фрибэг вышел из контейнера, ЗП из фрибэга - нет.

Main Canopy Crossfire 135, wingloading 1.45 - we know not a very optimal canopy for wingsuiting

Jumps 2339 - but only 25 total wingsuit jumps reported (15 on the V3 that was also on during the fatal jump). We know that a V3 is recommended with a minimum of 150 wingsuit jumps experience.

2 cameras on a tonfly diable converter 3 helmet, both mounted on the left side. Standard tonfly box with what looks like cx100 had the case ripped. It is reported that GoPro was mounted on top of the cx100 box.
You all can scroll down the report for pictures and imagine how scary the set up must have looked like.

Reported only 59 seconds of freefall from 4090 meters (13,400ft) to 1130m (3700ft) recorded by altitrack.
Jump was with 2 other wingsuiters, no report of a spin (not sure why only 59s of freefall recorded - insufficient skill? diving for speed?)

Now what's in the report:

Main canopy without any damage.

Reserve without damage. There were dark marks/smudges on the reserve bridle (40cm from the freebag) that were consistent with the helmet camera box coloring (material - I assume paint pic 2).
Similar smudges were seen on the bungee stow (pic 1) and on the reserve lines.

There is reported damage to the back of the left leg strap (under pic 2, page 3)
There is also a picture of AAD cutter, with description "AAD - destroyed during accident. (Below picture of the) Cutter after activation"

Wingsuit - damaged from accident, wing cutaway system was not used.

Helmet - damaged, GoPro camera installed above the Sony was ripped off.

Audible -Optima, altitudes set for 1700 (5500ft), 1000 (3300ft), 500 (1650ft)

Altitrack - I posted above.

Below that info is just general info about the type of the jump - so wingsuit with camera, reserve opening, no weather factors involved and info about the deceased.
He was 41 and had a valid skydiver's license until July 17th 2013 (equivalent to uspa membership). 2339 jumps, 25 wingsuit (15 V3 and 10 smaller), he also had a valid medical certificate (type 2) until Jan 30 2013.

Then there is record obtained form the dropzone of his last 10 jumps there. Looks like he jumped a stiletto 120 usually and with the camera.

Fatal jump description:
Jump with 2 other people, also in wingsuits flying cameras. Uneventful freefall. Main canopy spin after opening. Cutaway with RSL initiating reserve opening.
It is also believed the jumper pulled the cutaway handle. Reserve canopy did not inflate, only a reserve pilot chute was seen above the jumper.

After gear inspection and witness reports it is implied that the reserve bridle snagged the camera box or the GoPro. The most probable snag point is 40cm from the freebag. It also appears that the reserve freebag came out of the reserve tray and trailed behind the jumper's helmet.
Some of the reserve lines also snagged on the GoPro mount.

Here are contributing factors to the accident:
- main canopy selection - square canopy is recommended. Because of the burble and body asymmetry during opening elliptical canopies are much more prone to line twists.
- RSL - having RSL while using cameras could possibly cause a canopy snag when body position is not optimal during cutaway.
- camera mount - unfilled gaps between the helmet and the box, no protection from elements sticking out from the helmet.
- no helmet cutaway - made it difficult to ditch the helmet in case of entanglement
- wingsuit wings were not cut away - made it more difficult to free hands

So I will just add that the last contributing factor is a bit weird - I assume he unzipped his wings but maybe he never did... the report does not state whether the arms were zipped up, it only says that the arm cut away system was not used. I don't see it as a contributing factor though.
