About 14:22, at a distance of about 80 km from Moskva-Domodedovo Airport and at an altitude of 9100m the crew reported the successive engine failure of all three engines and the loss of generators and navigational equipment. The crew decided to divert to Moskva-Domodedovo Airport (DME) for an emergency landing. Air traffic control radioed position reports but visual contact with the ground could not be obtained until breaking through the overcast at about 500 feet.The TU-154 landed to the right of the runway and continued until it struck a small earthen mound, causing it to split into three parts.

Location:ca 1 km from Smolensk Air Base (Russia) show on map
Phase:Approach (APR)
Nature:Executive
Departure airport:Warszawa-Okecie Airport (WAW) (WAW/EPWA), Poland
Destination airport:Smolensk Air Base (XUBS), Russia
Narrative:
A Tupolev 154M passenger jet, operated the Polish Air Force, was destroyed when it crashed on approach to Smolensk Air Base in poor visibility. All on board were killed in the accident, including Polish President Lech Kaczynski.
The airplane departed Warszawa-Okecie Airport (WAW), Poland at 07:27 local time, carrying Polish President Lech Kaczynski, his wife, several Members of Parliament, President of the National Bank of Poland Slawomir Skrzypek, Chief of General Staff Franciszek Gagor, the Deputy Minister of Foreign Affairs Andrzej Kremer and a number of passengers and crew members.
During the flight the crew was in contact with air traffic controllers at Minsk, Moscow and Smolensk. The crew also was in contact with the crew of a Polish Air Force Yakovlev 40 passenger plane that had landed at Smolensk Air Base 90 minutes ahead of the Presidential flight.
At about 10:14 the flight descended through an altitude of 7500 m. Minsk Control radioed that the visibility at Smolensk Air Base was 400 m due to fog. The same conditions were transmitted to the crew when they contacted the controller at Smolensk. About 10:25 the pilot of the Yak-40 on the ground at Smolensk radioed that horizontal visiblity was 400 m and vertical visibility about 50 m. Shortly afterwards they reported that an Ilyushin 76 transport plane had diverted to an alternate airfield after two attempts to land.
The crew continued preparations for an approach to runway 26 at the Smolensk Air Base. The cockpit door was open and during the approach there were two passengers present on the flight deck.
Meanwhile, visibility worsened to 200 m. This information was transmitted to the crew at 10:37. The crew requested permission to carry out a 'trial' approach to decision height (100 m) and asked the controller to expect a go around.
About 18 seconds before impact the terrain awareness and warning system (TAWS) sounded: "Pull up", followed by an aural warning: "TERRAIN AHEAD". About 5 seconds before impact the autopilot and autothrottle were disconnected in order to execute a go around. The airplane contacted upsloping terrain at a distance of about 1100 meters from the runway and 40 m to the left of extended centreline. The aircraft height at that point was 15 m below the level of the runway threshold. The left wing struck a large tree causing the airplane to roll inverted. The Tu-154 crashed and broke up.

>> Un expert polonez, despre dezastrul de la Smolensk:

"Acceleraţia la momentul contactului fuselajului cu solul sau copacii, a fost în medie de la 0,4g până la 4g (g = acceleraţia gravitaţională), ceea ce face foarte puţin probabilă moartea tuturor pasagerilor în timpul decelerării şi ca urmare a acesteia. A fost deasemenea imposibil pentru corpul aeronavei să efectueze o jumătate de rotaţie după pierderea imaginabilă de fragmente din aripă de la câţiva metri deasupra solului".

"Fuzelajul, tratat în calcule ca un tub fabricat în principal din duraluminiu armat cu ranforsări ("coaste"), in timp ce aluneca pe teren, ar fi trebuit să rămână întreg sau să se dezintegreze în nu mai mult de trei părţi. Dezintegrarea sa în zeci de mii de bucăţi este în contradicţie cu durabilitatea materialului, definită de mecanică. Acest lucru indică faptul că dezintegrarea fuzelajului s-a întâmplat cu siguranţă din alte motive, destul de evidente".

Din cate inteleg eu accidentul de azi a avut cauze serioase ( s-au oprit 3 motoare plus generatorarele) si pe deasupra nici vizibilitatea n-a fost buna.Cu toate acestea au fost numai doua victime

La Smolensk se zice ca doar vizibilitatea a fost proasta ( desi cu 40 de minute inainte aterizare alt avion) si in final au murit toti......

Riddick spunea...

Ăştia de la AviationSafetyNetwork bagă duda cu "a large tree". Un copac mare ar fi rupt aripa, asta nu explică terciuirea fuzelajului...

Crystal Clear spunea...

Foarte corect, ai dreptate !

Avionul de azi a avut o coliziune frontala cu un damb si s-a rupt in trei !

La Smolensk ruperea aripii a dus la o miscare de rotatie dar nu stim ce a
provocat "terciuirea fuzelajului" cum zici tu.

Explicatii a la "stiinta pentru toti"

Riddick spunea...

Necuratul, n'aşa ?!

Anonim spunea...

cine naiba mai poate crede ceva...cutiile negre ce zic?si astea pot fi falsificate?

Riddick spunea...

Cutiile negre pot fi falsificate dacă ancheta se face în statul în care avionul şi atentatul s-au produs, şi când guvernul celălalt este complice.

Crystal Clear spunea...

In ce capcana perfecta a cazut Kacynski !

Riddick spunea...

Polonia este un stat important, încearcă "unii" cu tot dinadinsul să îi controleze mişcările.


Citate din gândirea profundă a europeiştilor RO

Emil Boc, 2011: "Cred că se impune tot mai mult o dezbatere între politicieni şi state. Nu trebuie să ne temem să vorbim despre Statele Unite ale Europei. Poate nu azi, nu mâine, dar cred că trebuie să începem să vorbim despre asta, pe plan intern, în ţările noastre, şi după aceea la nivel european, fiindcă Statele Unite ale Europei nu înseamnă că statele îşi vor pierde caracteristicile lor, atuurile lor, ci vor dovedi voinţa supremă de a acţiona împreună, şi spre a putea reuşi într-o competiţie globală, ceea ce nu este uşor, trebuie să începem să vorbim despre asta."

Emil Boc, 2011: "Partidul Democrat Liberal susţine acordul interguvernamental de uniune fiscală şi ca România să adere şi să semneze acest acord. PDL susţine revizuirea Constituţiei pentru ratificarea acordului interguvernamental de uniune fiscală. PDL a susţinut şi susţine o Europă unită, o Europă cu 27 de state, o Europă nu cu două viteze, ci cu o singură viteză, o Românie care să fie alături de nucleul dur al Uniunii Europene. Pactul european fiscal este un pact împotriva politicilor populiste şi demagogice".
