2nd May 2010, 09:21
Swiss News are reporting that an Intersky Dash 8 en route from ZRH to EBA hit a power cable on final approach to Marina die Campo airport LIRJ on Elba Island in Italy.
The new managing director of Intersky blames the pilot,he is cited in the press saying "the plane must have been a few meters outside the glide path". (??)
Thanks God the plane landed safely.

Any experts here who have flown into LIRJ who can shed some light on the incident?

Only news-agency and newspaper publications so far.

The ANSV does not yet show the accident but then it was 1st of May and today is Sunday.

Local newspapers report that aircraft has landed with prop damage, Me thinks that even on Dash's the landing gear length exceeds the prop dia:eek:

As Basil mentioned, there are some videos on youtube, here is one with the same A/C type and airline involved in this incident.

If you look very very closely, perpendicular to the displaced threshold is a power line. That must be the one they hit.

If you scroll to 2:43 you see two poles below and behind the left wing.

Then at 2:59, much closer to the runway, you actually see a power line underneath the a/c.

There are also two separate power lines marked in the charts, but I am not sure if the one at 2:59 is the one referred to in the charts or not.

In one of the media reports the CEO of the airline (Bernatzik) was quoted in saying the power line was at "great height".

Couldn't find any historical Met data for LIRJ, prolly don't have a qualified observer, but checking LIRP/LIRF looks like a southerly wind component of between 10/15Kts, add to that the terrain to the S/E of the threshold plus the vis for those places has not been wonderful all day. LIRP 3000m in rain for instance

Flown there a few occasions in a B200, and it was certainly a challenge at the best of times.

Just happy that nobody was hurt.

A microlight pilot witness descibes rwy 16 in use, aeroplane arriving very uncoordinated, before hitting electric wires (8 metres high) had a 60° bank, entered airport area very unsettled, touched rwy halfway down and bounced 3 times.

if you check Incident: Intersky DH8C on May 1st 2010, touched power line on final approach (http://avherald.com/h?article=42aefed0&opt=0)

you will see where they hit the powerline: the powerline was 9 m:eek: (!!!) high and 1000 m(!!!!) :eek:from the threshold......also check the metar looking very similar to the tu154 accident recently....you wonder why they press on in this wx for a visual approach in mountainous terrain.......

I think as long as the prop radius is less than the landing gear length (or threabouts - depends what you measure it from) you should be ok.

Glad to see nobody was hurt.

Am I misunderstanding something (I'm just a SLF), or was there a tailwind? Would this perhaps have led to a downdraft as the Dash crossed the high terrain on approach?

hmmm if they were on runway 16, with a southerly, .. no tailwind.
Possibly some sink in the area downwind of the terrain, or just plain lumpy when you need it least !

It is a challenging approach in the best of conditions, the S340 video shows that rather well.

Looks like groundfog, or fog in the lower few hundred feet. Could be very well seen by the witness if he is situated a bit higher up in the valley than the airport. question is why a professional pilot would continue an approach in this weather in mountainous terrain....Pressure from the company?

nobody any pictures from the event or prop damage?where are the spotters when you need them.......

Flight İnternational:

InterSky, however, describes the weather during the approach as "normal". It has not indicated the type of approach being conducted when the incident occurred.
But managing director Claus Bernatzik says: "The aircraft seems to have been located, on approach, a few metres off the intended flight path.:confused:

İf it is true they hit a 9m high powerline 1000 m from the runway,surely they where more than a few meters from the intended flight path.

either this guy bernantzik does not know what he is talking about or he is trying to cover the whole thing up with soft talk, or both.

if the wx was good according to the company it does not make sense why a pilot with "decades of experience" will make 60 degr bank turns and hit a powerline 1000 m before the runway. sounds more to me as a pilot trying to find the runway in fog conditions..........

luckily nobody hurt

could not open the pictures but the site is Marina di Campo (Isola d'Elba): Dash Intersky da ZRH trancia cavi elettricità - Pagina 3 - I forum di Aviazione Civile (http://www.aviazionecivile.com/vb/showthread.php?t=108545&page=3)

halfway the page are the pics

hopefully the moderators will allow the adress as it clearly shows it was indeed very foggy.

Also important to note is that with a damaged prop but gear and fuselage intact the aircraft can only have hit the high voltage powerline in a very steep bank close to the ground.

the gpws must have sounded continiously or was it perhaps switched off as to avoid nuisance warnings:E like close by hills and terrain?

obviously the weather was not that bad. you can not fly an approach like this with 100m vis.
somewhere else I found that the met station should be around 8nm southeast of the airport, so not very reliable

HeadingSouth
3rd May 2010, 10:53
bank angle of 60° ? not bad a manoeuver that close to terrain. I however dare not to believe that bank angle indication when hitting the cable.
If the power line is 9m above ground and you'd hit it with the prop at a bank angle of 60° then you'd probably touch the ground with the wingtip the very next second.

somehow lucky they hit the line with the prop, not with the wing or gear...

Maybe they should put a hook on Dash Eights, seems a shame to waste such a handy wire!

Air Tourer
3rd May 2010, 10:56
Well it seemed to me to be high ground all the way in, so the 9m would be just above ground height. Some trees looked in danger of getting wacked also, in the video. And the undercarrage length has nothing to do with anything in this context.

HeadingSouth
3rd May 2010, 12:44
Flying a meter higher and - well if the prop had missed the line and the line would have tangled up in the wheels somehow... not a nice thought.

I once saw a Mooney M20 being entangled with a wire. It ended catastrophically for the Mooney. And yes I know a Dash 8 is a different set of plane. Still...

3rd May 2010, 13:20
Hello Guys,

i think the distance is not true.

From what i know, the wire is somewhat 150-200 Meters away from the RWY.

Visibility was not bad, more than 10 Kilometers.

Pilot is called to be one of the experienced @ InterSky, with at least 30years flying and +20.000flthrs

mickjoebill
3rd May 2010, 13:38
since the prop is mounted ahead of the main gear, then a cut line wouldn't have damaged the wheels - surely the lack of gear damage is a red herring?

You are all assuming it passed over the wire!

3rd May 2010, 14:02
"From what i know, the wire is somewhat 150-200 Meters away from the RWY."

There is another wire as you can see on the airport diagram a page earlier

"Visibility was not bad, more than 10 Kilometers."

That does not agree with the pictures taken right after the accident, the hill tops are not even visible and the cloudbase is low

it does not make sense then that he hit a cable so far from the runway and banked 60 degr if the wx had been so great he?

"30000+ hours"

does not mean a thing.even with all the gadgets on board.

something smells not right about this accident...the facts do not add up.....unless the cable was raised 1000 ft up:ok: or the pilot was not wearing his glasses and the co pilot happened to look just the other way:bored:

or was he afraid to speak up or interfere? was he flying with a management pilot perhaps, intimidated by his experience:E?

an old pilot told me once:your priorities in flying should always be :Life-Licence-Job. that has and will not change.fly safe.

Hitting any sort of electric cable ( i.e with metal iside) at say 150 Kts will go through metal like a cord in butter. Hitting a propeller only and not have any fuselage colateral damage is very strange I would say.

I have some years ago seen pictures of a glassfiber glider cut in 2 ( unfortunately also the pilot ) by a small cow-fence electric wire during a attempted landing into a field , and the estimated landing speed of that glider was less than 60 Kts.

I have to agree I'm struggling to understand how the prop was damaged and nothing else. If the a/c was banked, the wing surely would have been damaged as well as the prop. If the a/c flew over the cable, the fuselage would have been damaged as it 'hangs' lower than the bottom of the prop disc.

SomeGuyOnTheDeck
3rd May 2010, 15:58
At the risk of making an idiot of myself again, can I suggest that there may be evidence from the photos of minor fuselage damage adjacent to the prop?

Between the last 'w' int the 'www.t-city.de' marking and the window above, there is what looks like a dent. To the left and below the first 'w' is a liniar mark running down and back, and running from the lower end of this forward and down is what looks like more damage. Whether this was caused by the wire, by fragments from the prop, or indeed is just dirt, I don't know.

Piece of Cake
3rd May 2010, 18:04
SomeGuyOnTheDeck-There is indeed some damage to the fuselage, just under the window and also about 4ft below that (and slightly aft), these dents are outside the re-inforced composite panels which are desigend to protect the fusealge from ice being shed from the props.

There is also a hefty dent on the front right hand side of the engine cowling, in the 8-9 O'clock position in relation to the prop... that's expensive.

SomeGuyOnTheDeck
3rd May 2010, 18:43
Yes, Piece of Cake, I'd missed that. Possibly the spinner was lost in the incident too. At a guess, I'd say the wire was whipped round as it hit the prop, from the marks on the fuselage. Nasty...

Though the map seems to indicate power lines running roughly east-west across the flightpath, the photos also show other wires (possibly phonelines) running north-south. I wonder if it was one of these that was hit? This might explain how the prop got the worst of it, though it rather implies that there would have been a near-miss with a pole or two.

Edit ---
Looking at the map again, the power lines are more or less aligned with the flightpath at some points anyway, rather than perpendicular to it.

The right hand side windsheild wiper looks to be bent upwards at the inboard end.

I was parked next to this aircraft at ZRH on Saturday and and noted the Captain doing his walk around. Not that I have anything to say about that but I almost went over to ask what airline they were due to the hybrid colour scheme.

Very glad to be looking at a lightly damaged aircraft on the net rather than reading the headlines in the paper.

You are all assuming it passed over the wire!

I think you have got it if you see the damage to the prop is at about the diameter that is about the distance to the top of the fuselage.

Runway101
4th May 2010, 10:27
that's expensive

The airlines CEO yesterday estimated the damage to be 100k Euro, mostly for the rental of a replacement a/c.

He also told the press that visibility was 10km at the time of the incident.

Looks like there is also a slice on the tail just slightly higher than line of damage to the prop.


Any chance that the aircraft went under the powerline rather than over?

That wasn't the question ... where is the report ??
A line or two in the press about how much it was going to cost to fix the plane does not constitute information that may prevent future incidents with possible loss of life which appears to have been a distinct possibility here. Almost 18 months on .... nothing.

When an incident occurs with a G-reg the AAIB investigates with the assistanceof the local authorities no?If you're talking about an Annex 13 investigation, no.

For an accident or serious incident falling within the remit, Annex 13 says:

5.1 The State of Occurrence shall institute an investigation into the circumstances of the accident and be responsible for the conduct of the investigation, but it may delegate the whole or any part of the conducting of such investigation to another State or a regional accident investigation organization by mutual arrangement and consent. In any event, the State of Occurrence shall use every means to facilitate the investigation.

and

5.18 The State of Registry, the State of the Operator, the State of Design and the State of Manufacture shall each be entitled to appoint an accredited representative to participate in the investigation.

The plane had to go under the wire otherwise there would be damage to the nose and radome.

If you mentally rotate the prop to the vertical downward, this becomes obvious.

Also, it hit at an angle since there was no damage the the left prop.

2. Definition of a Serious Incident

“Serious Incident” means an incident involving circumstances indicating that there was a high probability of an accident and is associated with the operation of an aircraft, which in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time it comes to rest at the end of the flight and the primary propulsion system is shut down.

The incidents listed below are typical examples of serious incidents. The list is not exhaustive and only serves as a guide to the definition of ‘serious incident’.
A near collision requiring an avoidance manoeuvre or when an avoiding manoeuvre would have been appropriate to avoid a collision or an unsafe situation.
Controlled flight into terrain (CFIT) only marginally avoided.
An aborted takeoff or a takeoff using a closed or engaged runway, a taxiway or unassigned runway.
A landing or attempted landing on a closed or engaged runway, a taxiway or unassigned runway.
Gross failure to achieve predicted performance during takeoff or initial climb.
All fires and/or smoke in the cockpit, in the passenger compartment, in cargo compartments or engine fires, even though such fires were extinguished with extinguishing agents.
Any events which require the emergency use of oxygen by the flight crew.
Aircraft structural failure or engine disintegration, including uncontained turbine engine failure, which is not classified as an accident.
Multiple malfunctions of one or more aircraft systems that seriously affect the operation of the aircraft.
Any case of flight crew incapacitation in flight.
Any fuel state which would require the declaration of an emergency by the pilot.
Runway incursions classified with severity A. The ‘Manual on the Prevention of Runway Incursions’ (Doc 9870) contains information on the severity classifications.
Takeoff or landing incidents, such as undershooting, overrunning or running off the side of runways.
System failures, weather phenomena, operation outside the approved flight envelope or other occurrences which caused or could have caused difficulties controlling the aircraft.
Failure of more than one system in a redundancy system which is mandatory for flight guidance and navigation.
The unintentional or, as an emergency measure, the intentional release of a slung load or any other load carried external to the aircraft.

Ghostdancer
25th Mar 2015, 09:56
From a compliance and safety viewpoint, regardless of a state investigation, the Operator should have conducted its own internal investigation into the previous event. Was this done, what was the output, was the output acted upon? Does someone really have to be killed before consideration is giving to re-routing the power lines???:sad:




For my own interest, and I'm not familiar with the location, is it considered a Category C airfield?

Teddy Robinson
5th Sep 2015, 20:14
Still no report.

I really prefer to refrain for terms such as "brushing under the carpet" but it does appear that there is a distinct reluctance to share information pertaining to this serious incident in order to further the interests of flight safety awareness.
