https://www.independent.co.uk/news/w...-a9004401.html Sweden plane crash: Nine dead after aircraft carrying parachutists crashes into island Nine people have been killed after the plane carrying them to carry out a parachute jump crashed into an island in eastern Sweden, local media reported on Sunday. The plane left Umea airport shortly after 1.30pm, The Local reported, and sounded an alarm at 2.12pm, before crashing. Region Vasterbotten municipality spokeswoman Gabriella Bandling said: "I can confirm that all those aboard the plane have died". Speaking to regional media, witnesses have claimed they could see parachutists attempting to jump out of the plane as it careened into the ground. Footage of the crash captured by a local 16-year-old showed the plane spiralling as it nosedived into Storsandskar, an island close to the airport. Airport operators have claimed the plane was a GippsAero GA8 Airvan – a small aircraft popular with skydiving operations that is designed to carry eight people including the pilot. Local rescue service representative Conny Qvarfordt told local media “It's a parachute plane, and something seems to have happened just after take-off.” Police are now working to identify the passengers as they pick apart the circumstances behind their deaths. The Swedish Prime Minister Stefan Lofven said he had received the news “with great grief”. He added: “I think of the dead and their relatives in this difficult time”. The speaker of the Swedish parliament Talman Andreas Norlen added: "Every person has an infinite value. When nine people are pulled away at the same time, a large tear occurs in our social fabric. “Let us give a thought to those who died in the air accident at Umea, but also to their closest and all others whose lives will never really be the same again." |
I've a thousand hours or so flying a skydive Airvan. It's docile, you have to work hard to crash it.
The video is horrifying. I see no tail in the video but the fuselage seems long. Possible accidental deployment of a tandem parachute? But again I can't see it breaking off the tail which is high. Skydivers can hit it if they try hard. Also nine is a heavy load for an Airvan. We could get eight with minimum fuel. But without tandems. Yes it's nose heavy empty, you'd run out of trim and have to hold nose up on landing so clearly it was designed to minimise the possibility of being unbalanced with a heavy load to the rear. But nine is heavy. Obviously if they find the tail separated??? |

Vertical dive with rolling Nothing relevant on video that I can see - Sounds like audio of press interview or other discussion but I don't know Swedish. |
It appears to be confirmed that the airplane disintegrated in the air. Apparently they are looking for parts and are asking the population to look out and report.

There has been pictures of parts of a wing (right wing, with stall warning sensor as far as I could tell), as well as what looked like parts of the horizontal stabiliser. Both these parts (and probably more) were found in the river some distance from the crash site. There were witness reports saying that some parts came down _minutes_ after the fuselage, which sounded very strange. But a possible explanation could be a parachute got entangled in the tail section or similar, and the (parts of) wing(s) came off due to high g loads in the spin following disintegration.
According to Flightradar24 the plane was at 13.400 feet at the moment of crash, and they were ready to drop. |

They're grounded EASA wise, looks like it broke up in flight. On 14 July 2019, a fatal accident occurred with a GA8 ‘Airvan’ aeroplane, duringa flight where the purpose was to drop parachutists.Indications are that the aeroplane, at 4 000 meters altitude,suffered structural failure. Early reports are that a wing may have detached from the aeroplane prior to the accident, but,at this time, the root cause of the accident cannot be confirmed. |
It’s a big call to make by grounding them. Especially if the tail was damaged by skydivers and the wing was subsequently lost. |
How is that a big call? A sensible "safety pause" whilst the event/failure scenario can be determined. I would say it is a prudent call.

Yes it would be silly to ground an aircraft that had a wing structural failure after the tail had already been torn off due to outside influences (such as overspeed after stall, or entanglement with a parachute).
We don't know what the actual failure scenario was though. The question is whether they are grounding because (a) due to specific evidence that they suspect a structural problem, or (b) they are the type to ground something when they don't yet have any evidence either way. Wait and see. The EASA AD is vague as to the reasons for its decision, as it says it is both following the lead of Australia's temporary grounding, and using "all available information". |

Directive issued last year:AD/GA8/9 Airworthiness Directives as madeThis instrument amends certain part replacement times which were recently mandated by AD/GA8/9. As Australia is the State of Design for the type, CASA is required to develop, and to transmit to other States of Registry, an airworthiness directive (AD) to correct the problem. The AD sets out required remedial action to replace certain GippsAero GA8 wing struts and wing strut fittings within specified timeframes in response to a manufacturing quality escape which resulted in wing strut fittings in the effective serial number range to be manufactured with incorrect grain orientation.Administered by: Infrastructure, Transport, Cities and Regional Development
AIRWORTHINESS DIRECTIVE On the commencement date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below repeals Airworthiness Directive (AD) AD/GA8/9 and issues the following AD under subregulation 39.001 (1) of CASR 1998 and subsection 33 (3) of the Acts Interpretation Act 1901. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct an unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Grounding lifted
Reason:On 14 July 2019, a fatal accident occurred with a GA8 ‘Airvan’ aeroplane, duringa flight where the purpose was to drop parachutists.Indications were that the aeroplane, at 4 000 meters altitude,suffered structural failure. Early reports (later confirmed) indicatedthat a wing detached from the aeroplane prior to the accident. At thetime, the root cause of the accident could not be confirmed.The Civil Aviation Safety Authority (CASA)of Australia, the authority of the State of Design of the affected type design, issuedalegal instrument, temporarily prohibitingoperations of the GA8 Airvan in Australia, which tookeffect on 20 July 2019 and planned tobe validfor 15days.Based on all available informationat the time, and taking into account the Australian legal instrument, EASA issued Emergency AD 2019-0177-Eto prohibit all flights, thereby groundingthe affected aeroplanesregistered in EASA Member States, until further notice.Since that AD was issued, CASA Australia informed EASA that the results of the physical inspection of the accident aeroplane indicate that it appearsto have been exposed to aerodynamic loads beyondthose for which the type designis certificated. No evidence was found to indicate that anEASA AD No.: 2019-0177-CNTE.CAP.00116-007© European Union Aviation Safety Agency. All rights reserved. ISO9001 Certified.Proprietary document. Copies are not controlled. Confirm revision status through the EASA-Internet/Intranet.An agency of the European UnionPage 2of 2unsafe condition exists or could develop that would warrant AD action under Regulation (EU) 748/2012, Part 21.A.3B.Based on allavailable information, EASA has decided to allow GA8 aeroplanes to fly again.For the reasons describedabove, this Notice cancels EASA Emergency AD 2019-0177- |
I imagine the footage of one or several cameras on on board will have been reviewed by now as well. No doubt light has been shed on cause. Speculation perhaps they will have revealed one of a couple of scenarios.
Premature deployment of a parachute causing loss of control followed by structural failure of both tail and wing. Loss of control after inadvertent or otherwise entry into IMC with a subsequent overstress on attempted recovery. It's so easy to find yourself in a spiral dive after being distracted by the jumpers. Don't ask me how I know. Ice could be a factor too if in cloud. Even in the Summer months. A stall, spin on the run in is possible but most likely a few people would have got out in that case. Besides the Airvan has a docile stall even with everyone crowding the exit. As I said speculation but borne of experience flying the Airvan on Skydive ops. |
