Four Killed as Small Plane Crashed in Slovenia

A small plane crashed near Ajdovscina in western Slovenia on July 14th.

The 6-seat Piper 32 plane was heading from Venice, Italy, to Leipzig, Germany, when it went down.

There were four people aboard at the time; all of them were killed in the crash. It is believed that the founder of German internet company ‘Unister’ Thomas Wagner, 38, was among those killed in the crash.

The plane was registered in the United States.

Authorities said the pilot reported problems with icing before the plane crashed.

BEA on SwiftAir Air Algeria (Burkina Faso to Algiers) Crash July 2014

Accident 24 July 2014 in Gossi, Mali to the MD-83 registered EC-LTV operated by Swiftair S.A.

Press release from the BEA and the Commission d’Enquêtes Accidents et Incidents de l’Aviation civile (Mali)

Following the publication of the Interim Report on 20 September 2014 in Bamako (Mali), investigative work has continued, based on the analysis of the accident flight parameters. Progress made in this work has led the Republic of Mali Commission of Inquiry and the BEA to communicate jointly the following information.

On 24 July 2014, the MD-83 registered EC-LTV was performing scheduled night flight AH 5017 from Ouagadougou (Burkina Faso) to Algiers (Algeria). Takeoff occurred at 01h15, the climb towards the cruise altitude took place without any significant events, and the crew made several heading changes in order to fly around a storm cell. The autopilot and the autothrottle were engaged. The aeroplane reached the cruise altitude of 31,000 ft, that’s to say about 9,500 m. The autopilot then switched to the mode that maintains the altitude and the autothrottle to the mode that maintains the speed (Mach).

About two minutes after levelling off at an altitude of 31,000 ft, calculations performed by the manufacturer and validated by the investigation team indicate that the recorded EPR , the main parameter for engine power management, became erroneous on the right engine and then about 55 seconds later on the left engine. This was likely due to icing of the pressure sensors located on the engine nose cones. If the engine anti-ice protection system is activated, these pressure sensors are heated by hot air.

Analysis of the available data indicates that the crew likely did not activate the system during climb and cruise.

As a result of the icing of the pressure sensors, the erroneous information transmitted to the autothrottle meant that the latter limited the thrust delivered by the engines. Under these conditions, the thrust was insufficient to maintain cruise speed and the aeroplane slowed down. The autopilot then commanded an increase in the aeroplane’s pitch attitude in order to maintain the altitude in spite of this loss of speed.

This explains how, from the beginning of the error in measuring the EPR values, the aeroplane’s speed dropped from 290 kt to 200 kt in about 5 minutes and 35 seconds and the angle of attack increased until the aeroplane stalled.

About 20 seconds after the beginning of the aeroplane stall, the autopilot was disengaged. The aeroplane rolled suddenly to the left until it reached a bank angle of 140°, and a nose-down pitch
of 80°

The recorded parameters indicate that there were no stall recovery manœuvres by
the crew.

However, in the moments following the aeroplane stall, the flight control surfaces remained deflected nose-up and in a right roll.


At least two similar events occurred, in June 2002 and in June 2014, with no serious consequences.

The event in June 2002 was the subject of an NTSB investigation report. On 4 June 2002, the McDonnell Douglas MD-82, registered N823NK performing Spirit Airlines flight 970, suffered a loss of thrust on both engines, in cruise at an altitude of 33,000 ft, that is about 10,000 m. The two pressure sensors, located on the engine nose bullets, were blocked by ice crystals, leading to incorrect indications and over-estimation of the EPR. The crew noticed the drop in speed and the precursor indications of a stall just before disengagement of the autopilot and putting the aeroplane into a descent. They had not activated the engine anti-ice systems. This event occurred during the day, outside the clouds.

On 8 June 2014, the MD83 registered EC-JUG belonging to Swiftair, which was performing a passenger transport flight at flight level FL 330, suffered a drop in speed while it was flying during the daytime above the cloud layer. The crew detected the problem, put the aeroplane into a descent and activated the engine anti-ice systems without reaching a stall situation, then continued the flight.

This background, as well as the data on the accident to flight AH5017, was shared with the European Aviation Safety Agency (EASA) and through EASA with the American authorities (FAA); they should serve as the basis for future publication of corrective measures aimed at assisting crews in identifying and responding to similar situations to those encountered at the time of this accident.


The investigative work is continuing, in particular on the analysis of:

the flight parameters to complete the scenario described above,
possible crew reactions, despite the absence of Cockpit Voice Recorder data from the accident flight, which remain unusable to this day,
the training and follow-up of Swiftair crews,
previous events and the follow-up undertaken.

The publication of the final report is planned before the end of December 2015.

1 Killed, 2 Injured after Cessna Crashed in Central Wisconsin

Cessna in snowA single-engine Cessna 182 crashed near Owen in central Wisconsin at around 11 a.m. on January 26.

The plane, carrying the pilot, Mark Siegwart, 27, of Hammond, Indiana, Nathan Smoot, 41, of North Pole, Alaska and Martin Siegwart, 56, of Boon, Michigan, was flying from Hammond, Indiana when it went down.

According to Clark County Sheriff Greg Herrick, “Nathan and Mark were friends and were flying the recently purchased plane back to Alaska from the Griffith Airport in Hammond, Ind…Along the way, they stopped in Cadillac, Mich., and picked up Mark’s father who was accompanying them on the trip.”

According to the pilot, the aircraft began to ice up and lose altitude. He was attempting an emergency landing on a road when it crashed.

Martin Siegwart was pronounced dead at the spot, while Mark and Nathan were injured. Both of the injured were shifted to hospital where the authorities confirmed that Nathan was later discharged while Mark was in stable condition.

UTair Passengers Push Their Jet to Free it From Ice

UTairThe Passengers of a UTair flight had to push their jet at Igarka airport, Russia, after its brakes froze in minus 52C temperature.

The incident happened on November 25, when the plane was scheduled to fly from Igarka to the regional capital of Krasnoyarsk, with 74 passengers aboard.

According to the local transportation prosecutors, “Due to the low air temperatures, the chassis’s brake system froze and a tow truck was unable to move the plane onto the taxiway to carry out the flight…The passengers on board got out of the plane and started pushing it onto the taxiway.”

The passengers, mostly oil and gas workers, kept pushing the Tupolev-134 jet several meters on the taxiway. The flight was then able to take off successfully.

The incident is under investigation.

Transwest Plane Makes Emergency Landing due to Icy Windshield

transwest airA Transwest Air plane had to make an emergency landing in Stony Rapids, Northern Saskatchewan, Canada, at around 8 p.m. on November 20.

The Piper Navajo aircraft, which departed from Stony Rapids at around 7 p.m., faced heavy ice built up on the windshield during the flight to Fond-du-Lac. Authorities said the plane had to turn back because Fond-du-Lac airport did not have facilities for de-icing.

The plane landed without incident. Transwest Air chief operating officer Garrett Lawless said that hot air from the engine was used to clear a section of windshield. He confirmed that all 7 people aboard, including 2 pilots and 5 passengers, remained unharmed.

Flight Slides off Runway

On January 9, 2013, a Jazz Air flight operating as Air Canada Express–flying a de Havilland DHC-8-402Q Dash 8 made a safe landing at John G. Diefenbaker International Airport in Saskatchewan Canada.

The plane was taxiing when it struck ice, and veered off runway into snow where it was mired, blocking the runway.

The fifty-six passengers aboard evacuated with the assistance of emergency crews at about 6:30 after waiting about half an hour for a Saskatoon Transit bus from Tarmac to the gate. Weather conditions at the time were reported as heavy fog causing and near zero visibility in Saskatoon. It looks really cold, doesn’t it?

Engine Icing Warning for 747 and 787

Boeing warned 15 carriers to avoid flying the 747 and 787 near “high level thunderstorms” because of a risk of engine-icing problems. Six incidences of GEnx engines losing thrust at high altitude because of a buildup of ice crystals behind the front fan led to Boeing issuing a notice probating flying at high altitude within 50 miles of thunderstorms.

In the meantime, GE and Boeing are working to control the problem.

Piper Lands in Canadian Blizzard

On Jan 29, 2013, at 9:15 a.m., an Image Air Charter Ltd Piper PA-46-500TP Malibu Meridian was en route from La Crete, Alta to Three Hills (Canada) with three people aboard when it attempted to land in bad weather at Three Hills Airport.

The plane descended into a blizzard, and at one end of the runway struck an ice berm that knocked off the left wing. One wing and the landing gear were damaged. Conditions were so bad that no one at the hanger knew there was an accident until emergency crews arrived. Three Hills RCMP, Fire and EMS responded. An environmental services company cleaned up the fuel leak.

One passenger who was suffering chest pains was taken to the hospital.

The 2008 Piper PA-46-500TP Turbo Prop is registered to Image Air Charter Ltd.

The NTSB is investigating.

Contention Grows over Cause of May 2011 Sol Tragedy

What: Sol Linaeas Aereas Saab 340A
Where: 20 km (12.5 mls) N of Prahuaniyeu, RN Argentina
When: May 18, 2011
Who: 3 crew, 19 passengers
Why: Was it wing icing, a failure of the inlet deicing system or pilot error which caused the May crash which killed 22 people? The plane was flown by pilots John Raffo and Adriano Bolatti.

The brother of John Raffo, Víctor Raffo cites his brother’s 2400 flight hours, and denies that the crash was the pilot and copilot’s fault. With that many hours under his belt, John knew how to fly, he knew the area, he knew about icing.

These are the questions which are nagging at experts who disagree over the causes. The investigation is ongoing, but there is disagreement.

The flight stalled and then lost control, and impacted the ground, apparently due to wing icing. Was the pilot’s flight plan at fault? Was there a lack of situational awareness among the crew? It is all speculation now, until facts are turned up the investigation.

The pilot’s decision to descend is also being questioned.

Some say the pilot’s decisions are moot, and that the plane was not in optimal flying condition to begin with, as it had failed two mandatory inspections.

Portions of the transcription of the pilot’s dialogue have been published, but we have not heard the actual audio. Desde la Asociación de Pilotos de Líneas Aéreas, a pilot association, is threatening action because of transcription inaccuracies, mistakes and misinterpretation. We apologize for any errors, as we can only repost the transcription, as we don’t have the audio.

Where: 20 km (12.5 mls) N of Prahuaniyeu, RN Argentina
When: May 18, 2011
Who: 3 crew, 19 passengers
Why: After the last radio contact at 20:50, the aircraft crashed near Los Menucos en-route Neuquen to Comodoro after declaring an emergency and requesting descent out of icing conditions. There were no survivors of the 19 passengers and 3 crew.

There were newspaper reports of the flight coming down as a fireball, but that has been interpreted as journalistic license. We apologize if our translations reported this incident as a falling fireball when the fire apparently began after ground impact.

The pilot asked to descend from 5.800 meters to 4.300 due to ice. In the last communication ATC was informed that “the flight was was at 1.000 metres and going back to NQN.”

Wing Icing and a failure of the inlet deicing system is being considered as responsible. The black boxes were recovered.

The investigation is ongoing.


Family Charges Bombardier with Negligence

The National Transportation Safety Board’s decision on the Colgan Air Flight 407 crash is that the pilot responded inappropriately to the stick shaker, which led to an aerodynamic stall from which the airplane did not recover. The stick shaker only comes into play when the plane is already slow enough to stall. The plane fell 800 feet before crashing pointing northeast, away from the airport

The family of Ellyce Kausner has filed a lawsuit against Bombardier. Bombardier is the manufacturer of the plane involved in the crash. The suit charges that Bombardier was “negligent and careless” in the design of the plane by not providing more efficient internal mechanical warning systems.

Kausner was a 24 year old Jacksonville law student traveling to NY to visit family.

At least 19 other families have filed suits.

At the time of the crash, the automated “stick-pusher,” pushes the control column down in order to send the aircraft into a temporary dive so it can regain speed and recover from a stall but Capt. Renslow yanked back on the controls while adding thrust, manually overriding the stick-pusher.

Colgan Air, Clarence Center, NY, Accident Dockets

George’s Point of View

Time for Bombardier to step up to the plate. Although this has little to do with the pilot, who had flunked numerous flight tests during his career and was never adequately taught how to respond to the emergency that led to the airplane’s fatal descent. Maybe Ellyce would still be here if the warning systems on the Bombardier were simply better.

When the plane slowed down to a dangerous level, it set off the stall-prevention system, and the pilot performed the opposite of the proper procedure. So there were hiring and training issues involved too. And Captain Renslow had about 109 hours of experience, hardly enough to be pilot.

Even if procedures seem counter-intuitive, shouldn’t the pilot be aware of them?

Barring the inefficiency of an ill-prepared pilot, shouldn’t Bombardier have some kind of way to limit ineffective pilot responses?

When the hiring and training fails, and when the pilot fails, shouldn’t there be some kind of fail-safe within the plane? Even a copy of the Complete Idiot’s Guide to Not Crashing your Bombardier for pilots who flunked their last check write 16 months before and who apparently didn’t read the real manual?

Qantas Emergency Landing in Sydney

Contact photographer Ryan Hothersall

What: Qantas Boeing 737-800 en route from Sydney to Brisbane
Where: Sydney
When: Jul 26th 20
Why: While en route, the anti-icing system of the 737 failed. The flight diverted to Sydney and made a safe landing–after having experienced the same problem on the 25th.

It would be interesting to know the details of the system failure. Around this time last year, Air France Flight 447 went down in mysterious circumstances; it is speculated that the pitot tubes froze over, and that the fly by wire Airbus (unlike this Qantas Boeing) was rendered uncontrolled.

So if this was a frozen pitot tube situation where the pilots were able to make a safe landing in a Boeing, one wonders if aspects of Airbus fly by wire should be re-considered.

But this is food for thought only, as I do not have the exact details of the anti-ice system failure.
