Antonov AN-148 precipitato in Russia (Thread Tecnico)

[JT8D]

Rilasciato il Final Report (non in inglese per ora):

"The crash of the An-148-100B RA-61704 was caused by erroneous actions of the crew during departure in instrumental weather conditions in relation to unreliable indications of the air speed caused by the icing (ice blockage) of all three dynamic probes of the pitot system, which led to the loss of control over the parameters of the aircraft's flight resulting in a dive and collision with the ground.

The accident falls into the category loss of control in flight (LOC-I).

The investigation revealed systemic deficiencies in the assessment of risk as well as risk control, the failure of the airline's flight safety management system as well as lack of supervision of training of flight crew by aviation authorities at all levels, which led to the issuances of certificates to aviation personnel and crew, who did not fully qualify.

Purtroppo una lunga serie di carenze, a livello di design, procedure, addestramento, organizzazione, che potete trovare nell'articolo linkato sopra.
