Spirit A320 engine fire due for bird strike on RTO

[SuperMau]

Come da titolo, un A320 Spirit Airlines ha avuto un incendio al motore destro durante un low speed RTO dovuto a un bird strike, in decollo da Atlantic City, qui trovate il report di Avherald.

I due filmati allegati sono veramente spettacolari....., evacuazione perfetta....

1. Fare casino
2. Prendere tutti i bagagli
3. Filmare tutto anche sullo scivolo
4. Fermarsi a raccogliere tutta la roba che cade
5. Pisciare il cane (importantissimo per estinguere l'incendio)
6. Farsi i c***i propri belli rilassati

Per noi nerd aeronautici, invece, una domanda.... ma con incendio motore in corso, non mi sembra corretto evacuare usando R1, come si vede nel video....o mi sbaglio?

Oh poveri noi, forse tra tutti il più preparato era il cane...

Lasciamo perdere riguardo l'evacuazione, come ha già ottimamente sottolineato SuperMau.......

Riguardo il danno al motore, oggi avherald ha pubblicato alcune foto dettagliate:

Oltre a vari danni all'estremità di diverse fan baldes, una di esse si è completamente fratturata alla radice.

E' stato rilasciato da NTSB il Final Report:

La frattura di una fan blade in seguito a bird strike ha provocato notevoli vibrazioni che hanno causato un danno a un fuel tube, come descrive il Final Report di NTSB:

"Upon further examination of the engine, it was discovered that two of the thermal management system (TMS) manifold lower aft mounting bracket securing bolts had fractured in shear overstress allowing the bracket to swivel/rotate radially outward. This is one of three mounting brackets that secure the TMS manifold to the engine and prevents excessive moment of the TMS manifold during operation. Along with the broken/sheared TMS lower aft bracket bolts, a crack was visible on the CP-09 fuel line that initiated in fatigue; the CP- 09 fuel line is attached to the TMS and contains high pressure fuel. The crack in the CP-09 fuel line was due to necking down of the material as the fuel tube bent and stretched (elongated) under the vibration/cyclic loads after the bird strike and not as a manufacturing issue.

The TMS manifold lower aft mounting bracket securing bolts fractured due to the high impact and vibration loads because of the fan blade release after the bird strike. Subsequently the TMS manifold was allowed to move radially back and forward from the engine in response to the engine vibrations that were recorded on the flight data recorder to be in excess of the 10 cockpit units which is the highest value that the flight data recorder will record. The CP-09 fuel line flexed, bent, and stretched under the cyclical radial motion of the TMS manifold until it cracked due to fatigue spraying high pressure fuel onto the hot engine cases igniting an undercowl fire".
