вот вам выдержка из европейских сертификационных требований для двигателей CS-E (они сравнимы с российскими, поскольку папа с мамой у них одни)
раздел 510 :
CS-E 510 Safety Analysis
...
(3) It must be shown that Hazardous Engine Effects are predicted to occur at a rate not in excess of that defined as Extremely Remote (probability less than 10–7 per Engine flight hour). The estimated probability for individual Failures may be insufficiently precise to enable the total rate for Hazardous Engine Effects to be assessed. For Engine certification, it is acceptable to consider that the intent of this paragraph is achieved if the probability of a Hazardous Engine Effect arising from an individual Failure can be predicted to be not greater than 10–8 per Engine flight hour (see also CS-E 510(c)).

(2) The following effects must be regarded as Hazardous Engine Effects:
(i) Non-containment of high-energy debris;
(ii) Concentration of toxic products in the Engine bleed air for the cabin sufficient to incapacitate crew or passengers;
(iii) Significant thrust in the opposite direction to that commanded by the pilot;
(iv) Uncontrolled fire;
(v) Failure of the Engine mount system leading to inadvertent Engine separation;
(vi) Release of the Propeller by the Engine, if applicable;
(vii) Complete inability to shut the Engine down.
кроме того есть требования по потере контроля над двигателем ... ведущим к катастрофическим последствиям :
Failures causing LOTC/LOРC must not exceed 0.003 pmh (0.3*10-8).
