Safety analysis.

CFR · 2024-01-01 · US · Title 14

(a) (1) The applicant must analyze the engine, including the control system, to assess the likely consequences of all failures that can reasonably be expected to occur. This analysis will take into account, if applicable: (i) Aircraft-level devices and procedures assumed to be associated with a typical installation. Such assumptions must be stated in the analysis. (ii) Consequential secondary failures and latent failures. (iii) Multiple failures referred to in paragraph (d) of this section or that result in the hazardous engine effects defined in paragraph (g)(2) of this section. (2) The applicant must summarize those failures that could result in major engine effects or hazardous engine effects, as defined in paragraph (g) of this section, and estimate the probability of occurrence of those effects. Any engine part the failure of which could reasonably result in a hazardous engine effect must be clearly identified in this summary. (3) The applicant must show that hazardous engine effects are predicted to occur at a rate not in excess of that defined as extremely remote (probability range of 10 (4) The applicant must show that major engine effects are predicted to occur at a rate not in excess of that defined as remote (probability range of 10 (b) The FAA may require that any assumption as to the effects of failures and likely combination of failures be verified by test. (c) The primary failure of certain single elements cannot be sensibly estimated in numerical terms. If the
