Exemption No. Issue Date (dd-mm-yyyy) Exempted Provision Issuing Office Petitioner Company Aircraft Model TC/STC/LSTC No. Purpose  Status RDIMS #
017-2024 17-06-2024 CAR 521.158(1) and AWM 533.27(f)(6) AARD Pratt&Whitney Canada Model Engine: PW127XT-S E-19

The purpose of this exemption is to permit P&WC to obtain an approval for a major change to the type design that results in a re-issuance of the type certificate data sheet (TCDS) for the P&WC engine PW127XT-S, where the amended type design to be approved contains design features that do not comply with the applicable standards of airworthiness for the High Pressure Turbine (HPT) shaft. The proposed major change would exclude the entire HP rotor shaft system from consideration in determining the highest overspeed that would result from a complete loss of load on a turbine rotor. The proposed major change would include a HP rotor shaft system that does not comply with paragraph 533.27(f)(6).

In particular, this exemption is intended to provide relief from the provisions specified under this exemption to allow P&WC to field a HP rotor shaft system with safety-related improvements as compared to the presently approved design.

019-2019 03-07-2019 CAR 521.158(1) and PARAGRAPHS 5(b)(1) AND 19(b)(1) OF THE UNITED STATES (U.S.) SPECIAL FEDERAL AVIATION REGULATION (SFAR) No. 23, AS AMENDED BY SFAR 23-1 AARD Viking Air Limited DHC-6 “Twin Otter” Series 400, as well as Series 1, 100, 110, 200, 210, 300, 310 and 320 aeroplane models  A-82 The purpose of this exemption is to permit Viking to obtain a design change approval for the DHC-6 “Twin Otter” Series 400, as well as Series 1, 100, 110, 200, 210, 300, 310 and 320 aeroplane models incorporating type design changes recorded in Viking Report AEROC 6.1.G.11 DHC-6 Certified Airplane – Basic Definition, where the design change to be approved contains design features that do not comply with the applicable standards of airworthiness for “Takeoff speeds” and “Operating limitations – Takeoff weight limitations” in accordance with SFAR 23-1.  In particular, this exemption is intended to provide relief from paragraphs 5(b)(1) and 19(b)(1) of SFAR 23-1, which require that the decision speed V1 be a ground speed (and not an airborne speed) and that the all-engines operating take-off distance at maximum take-off weight be determined accordingly. This exemption is intended to permit the approval of an aeroplane flight manual supplement (AFMS) containing Reduced Ground Roll – 20 Degree Flap Take-Off (RGRTO) procedures and performance data, where V1 is permitted to be an airborne speed.
The use of the RGRTO AFMS procedures and performance data allows the aeroplane to become airborne with a minimum ground roll, in order to facilitate operations on short and/or unprepared (rough/soft) surfaces, such as may be encountered when conducting flight operations from remote and sparsely settled locations.

005-2019 25-02-2019 CAR 521.158(1) and AWM  525.841(a)(2)(i) AND (3)  AARD Airbus S.A.S. A321-271N and A321-272N (A321neo), and models A321-271NX and A321-272NX (A321neo ACF) A-166 The purpose of this exemption is to permit Airbus to obtain an amended type certificate to include new engine option (NEO) aeroplane models A321-271N and A321-272N (A321neo models) and Airbus “Cabin-Flex” option aeroplane models A321-271NX and A321-272NX (A321neo ACF models), which contain design features that do not fully comply with the applicable standards of airworthiness for “Pressurized Cabins” in accordance with paragraphs 525.841(a)(2)(i) and (3) of the AWM [Change 525-22]. In particular, these aeroplane models contain design features that allow the cabin pressure altitude to exceed 25,000 feet for more than 2 minutes, following a decompression that results from an uncontained engine failure condition, whereby the applicable standards of the AWM are not met.  This exemption provides relief from the requirements of paragraphs AWM 525.841(a)(2)(i) and (3) [Change 525-22] for uncontained engine rotor failure (UERF) scenarios.  Approved 14960745
002-2019 17-09-2019 CAR 521.158(1) and AWM  525.807(g)(7)  AARD Airbus S.A.S.  A321-271NX and A321-272NX (A321neo ACF) A-166 The purpose of this exemption is to permit Airbus to obtain an amended type certificate to include Airbus “Cabin-Flex” option aeroplane models A321-271NX and A321-272NX (A321neo ACF models), which contain design features that do not comply with the applicable standards of airworthiness of the AWM [Change 525-23] specifying the maximum number of passenger seats permitted for all Type III exits. In particular, the proposed design exceeds the standard limit of 70 passenger seats permitted for all Type III exits, and therefore does not meet the standard.  This exemption provides partial relief from 525.807(g)(7) of the AWM [Change 525-23] by targeting exclusively the provision limiting the maximum number of passenger seats permitted for all Type III exits.  Approved 15103556
040-2018 13-09-2019 CAR 521.158(1)  and AWM 525.981(b)(2)  AARD Cascade Aerospace Inc. Bombardier DHC-8-402 A-142 Following our review, Transport Canada has determined that an exemption from AWM 525.981(b)(2) to allow approval of a change to the type design of the aeroplane model DHC-8-402 for the installation of an auxiliary fuel system, is not necessary.  Based on our review of the design proposed and the Federal Aviation Administration Notice of Proposed Rulemaking and Final Rule justification for the adoption of the amendment 25-125 to 14 CFR part 25, which is the source code for AWM 525.981, the exception in subparagraph (b)(2) is not applicable.

In consideration of the above, your request for an exemption from subsection 521.158(1) of the CARs with respect to paragraph 525.981(b)(2) of the AWM is therefore denied.

This exemption does not provide relief from other aspects of 525.809(a). Approved 14689069

In particular, these aeroplane models contain design features that allow the cabin pressure altitude to exceed 40,000 feet, and to exceed 25,000 feet for more than 2 minutes, after decompression from any uncontained engine failure condition not shown to be extremely improbable, whereby the applicable standards of the AWM are not met. This exemption does not permit a non-compliance with AWM 525.841(a) for any other system and structural failure events not shown to be extremely improbable. Approved 14744000

Bombardier aeroplane model DHC-8-402   The purpose of this exemption is to permit Conair Group Inc. to obtain a supplemental type certificate (STC) for the Bombardier aeroplane model DHC-8-402, where the change to the type design to be approved contains design features that do not comply with the applicable standards of airworthiness for the protection from serious injury during emergency landing conditions for occupants of berths intended for a non-ambulant persons.

This exemption permits approval of a type design where the L (R) ENG FLAMEOUT (Caution) messages are inhibited during the take-off and landing phases of flight. Approved 14412022

In particular, and in consideration of the possibility of this aeroplane model to conduct high-altitude airport operations into airports constructed at elevations greater than 13,800 feet above sea level, this exemption is intended to provide relief from the application of the subject provision in order to prevent nuisance presentation of the oxygen dispensing units when operating at high-altitude airports. This exemption would permit the dispensing units providing the required oxygen flow to be automatically presented to the occupants before the cabin pressure altitude exceeds 17,000 feet.  Approved 14050635
