Petition for Exemption
Docket No.: FAA-2023-0993.
Petitioner: Rolls-Royce Deutschland Ltd & Co KG.
Section(s) of 14 CFR Affected: Sec. 33.27(c).
Description of Relief Sought: Harald Lackner on behalf of Rolls-
Royce Deutschland Ltd & Co KG (RRD) is seeking relief from 14 CFR
33.27(c), which requires the highest overspeed that results from a
complete loss of load on a turbine rotor, except as provided by
paragraph (f) of this section, must be included in the overspeed
conditions considered by paragraphs (b)(3)(i), (b)(3)(ii), and (b)(4)
of this section, regardless of whether that overspeed results from a
failure within the engine or external to the engine. The overspeed
resulting from any other single failure must be considered when
selecting the most limiting overspeed conditions applicable to each
rotor. Overspeeds resulting from combinations of failures must also be
considered unless the applicant can show that the probability of
occurrence is not greater than extremely remote (probability range of
10-7 to 10-9 per engine flight hour).
Specifically, RRD is proposing the FAA grant relief to exclude the
integral disc drive arm connecting the flange of the low pressure shaft
to the stage 3 disc of the low pressure turbine rotor on the Model
BR700-730B2-14 engine from failure consideration in determining the
highest overspeed that would result from a complete loss of load on a
turbine rotor.
