On the first of August 2024, the École de Parachutisme Sportif de Vannes Bretagne organised a parachute drop for 14. The sky diving centre is a non-profit working their plane underneath AIR OPS.
The plane was a Cessna 208 Caravan, a single-engine turboprop, registered in France as F-HVPC and owned by the sky diving centre. It was configured for sky diving, with two benches, one in all which seats 5 sky divers and the second seven.
As much as three sky divers can sit on the ground between the benches or by the door, for a most of 15 sky divers.
Every parachute system included a harness, a reserve (backup) parachute, the principle parachute and an computerized security system designed to deploy the reserve as wanted. The parachutes are linked to their harnesses by way of risers: webbing straps that group the suspension strains.
When leaping from the plane, the sky diver pulls out the deal with and releases it, inflicting the small pilot chute to slide out of a material pouch on the again of the harness. The pilot chute catches air which initiates the deployment of the principle cover.
The parachutes had been inspected 4 months earlier than the leap, 4 April 2024, with the reserve repacked by an authorized packer and legitimate till 4th April 2025.
For the flight that day, there have been two jumps deliberate round 1,200 metres and 4,000 metres. (~4,000 ft and 13,000 ft).
At 1,200 metres, the primary jumpers had been three skilled sky divers practising precision touchdown and two college students underneath the supervision of the sky diving teacher. Then at 4,000 metres, the remaining sky divers and the trainer would leap collectively.
The sky divers carried out their gear checks on the bottom earlier than boarding and would repeat them through the climb earlier than reaching leap altitude. The deployment handles for the principle cover, reserve cover, and cutaway can simply turn out to be dislodged from their housings with minimal motion.
The trainer was liable for checking the gear of the 2 college students, which he did. He held C and D licences, permitting him to oversee different sky divers and carry out demonstration jumps. He was in coaching for the federal teacher ranking.
The pilot held a industrial licence with 6,600 flight hours, with 5,500 as a sky diving pilot.
It was a sizzling August day, 28-30°C (82-86°F) and it could have been sweltering within the cabin. They departed Vannes and climbed away, prepared for his or her jumps.
The sky divers had been sitting in line with their jumps, with the eight sky divers leaping second seated nearest the cockpit, with one on the ground between the benches. The sky diving teacher sat on the finish of the longer bench, with one scholar on the bench to the trainer’s left and one scholar to the best of the bench, sitting on the ground. The three skilled sky divers practising precision landings had been nearest the door, with one on the brief bench and two on the ground. The three sky divers on the ground (one scholar, two precision) sat shoulder to shoulder. Everybody was sitting with their backs to the cockpit.
The aft door was a vertical sliding design of Plexiglas slats. The Cessna 208 was licensed to fly with the door open as part of its sky diver operations. The one restriction was that the door ought to stay closed throughout take off and under 500 metres, in order that occupants couldn’t fall out at a top too low for the cover to deploy. The pinnacle of the sky diving centre confirmed that it was normal for the sky divers to partially open the door for some contemporary air when temperatures had been excessive, in an effort to calm down the cabin. There had by no means been any problem with partially opening the door. The pilot had explicitly given permission for this earlier than the flight.
The sky diver sitting on the ground closest to the door had been assigned the duty of working the plane’s vertical sliding door. He was very skilled: he held C and D licences and likewise a federal teacher ranking with 3,600 jumps logged. He had attended a briefing earlier than the flight to study in regards to the door and the precautions to take when working it. The pilot had informed him that he may partially open the door through the climb in an effort to ventilate the cabin.
It was extremely popular within the cabin. After checking for any anomalies, the sky diver raised the slats a bit to ventilate the cabin. He opened the door by about ten centimetres (4 inches) to let the air in, barely lower than the peak of a soda can.
The trainer, seated on the finish of the bench furthest from the door, began to test his college students’ parachutes. He began together with his scholar sitting on the ground. The extra skilled sky diver sitting subsequent to him on the ground shifted in the direction of the door to present the scholar some room.
The sky diver sitting by the door positioned his foot to behave as a door cease. He felt the sky diver within the center shift in the direction of the door and press towards him. He didn’t transfer however turned his chest to the best and leaned a bit out of the way in which.
Within the course of, he should have squashed the leather-based ball of the pilot chute between the parachute and the ground. What nobody realised was {that a} little bit of his pilot chute had come out of the material pouch.
The slipstream from the open door caught the chute and yanked it out of the plane. This triggered the principle container to open, the beginning of the sequence to deploy the principle cover.
The sky diver sitting on the bench heard one thing from the door. He turned to look and noticed the pilot chute of the sky diver nearest the door fly out of the plane. The primary cover container of the parachute was open and being dragged outdoors. He grabbed the suspension strains however he couldn’t pull the container again in.
The sky diver on the ground was relentlessly pulled in the direction of the door.
The primary parachute opened outdoors of the plane underneath the left horizontal stabiliser, the small wing on the tail.
Whereas the sky diver was being dragged out of the plane, the highest loop of the right-hand riser snagged on the door body after which snapped underneath the pressure. The primary cover was now solely partially linked to the harness.
The sky diver felt himself being pulled by way of the underside of the door, three slats breaking underneath the stress. He felt a pointy ache in his leg as he went over the edge. He didn’t comprehend it but however his leg was damaged.
The riser that snapped meant that the principle cover was now solely partially linked to the harness. The reserve cover deployed up and in the direction of the tail. It rubbed towards the horizontal stabiliser, sufficient to go away a mark, however fortunately didn’t get caught up within the tail.
The person sitting on the bench seemed out the damaged door and noticed the sky diver outdoors of the plane underneath the reserve cover, with the principle cover nonetheless partially linked.
From the sky diver’s perspective, he was all of a sudden outdoors of the plane. He rapidly noticed that the reserve had deployed however that the principle cover was nonetheless partially linked to the harness. He started to make use of the reserve cover to manage his descent whereas protecting the principle cover out of the way in which so it could not get tangled with the reserve. In the meantime, the earth was speeding at him.
He hit the bottom, onerous. He broke his again, fracturing 5 lumbar vertebrae. All he may do was lie there and wait for somebody to search out him.
In the meantime, within the cockpit, the pilot heard a loud noise. They had been at about 2,000 ft, midway to their leap altitude. His stick vibrated strongly. He wasn’t positive what was occurring and thought that an elevator could have failed. He pulled again on the facility and began to descend. The vibrations stopped however he determined it was higher to abort the leap, as he wasn’t positive what was unsuitable with the plane.
The sky divers should have been in shock. The one on the bench stated they had been already descending by the point he thought-about saying one thing, so he presumed the pilot realised what had simply occurred.
I believe it’s truthful to imagine that everybody was in shock.
They landed safely inside a couple of minutes. The pilot had no concept that he had misplaced a passenger till he had taxied to the parking stand. He instantly referred to as ATC to say they wanted an emergency seek for the sky diver.
There aren’t any particulars in regards to the search and rescue apart from that the pilot informed the BEA that the sky diver was “rapidly discovered” by the rescue providers.
In actual fact, normally, I’m disillusioned by the element within the BEA report. There are a selection of angles that appear to not have been explored in any respect. That stated, I like that the report is cautious to not assign blame or second-guess anybody’s choices. Cracking open the door to get some air into the recent cabin was authorised and the sky diver assigned to the door was skilled and correctly briefed. All the gear checks had been accomplished as anticipated.
The important thing right here is the positioning of the sky diver. This meant that the leather-based pilot chute ball was nearly definitely squished between the parachute and the ground. Many sky divers want the leather-based ball: it’s simpler to grip and doesn’t break as simply as a plastic ball. However the leather-based additionally slides much less simply, which explains why it bought trapped, pulling out the pilot chute.
Additional, the pilot chute pouch, on the best facet of the again, was immediately uncovered to the slipstream. It was a sequence of occasions that nobody had thought-about.
When the best riser snagged on the door body, the textile loop securing it severed, triggering the reserve deployment, precisely as designed. It was pure luck that neither cover caught on the horizontal stabiliser. The sky diver managed each canopies to the bottom, which speaks to his expertise stage.
The report concludes that though the danger of a parachute snagging on the horizontal stabiliser or elevator is a identified hazard of sky diving, nobody had thought by way of the interplay of the airflow from the partially open door.
On account of this incident, the sky diving centre not permits for the door to be opened throughout flight, not even partially, besides through the drop phases.
It should get awfully sizzling within the cabin however that’s nonetheless higher than all of a sudden discovering out you might be outdoors of it.
