14:3.0.1.1.7.32.3.1.16 : Appendix K
Appendix K to Part 121 - Performance Requirements for Certain
Turbopropeller Powered Airplanes
1. Applicability. This appendix specifies requirements
for the following turbopropeller powered airplanes that must comply
with the Airplane Performance Operating Limitations in §§ 121.189
through 121.197:
a. After December 20, 2010, each airplane manufactured before
March 20, 1997 and type certificated in the:
i. Normal category before July 1, 1970, and meets special
conditions issued by the Administrator for airplanes intended for
use in operations under part 135 of this chapter.
ii. Normal category before July 19, 1970, and meets the
additional airworthiness standards in SFAR No. 23 of 14 CFR part
23.
iii. Normal category, and complies with the additional
airworthiness standards in appendix A of part 135 of this
chapter.
iv. Normal category, and complies with section 1.(a) or 1.(b) of
SFAR No. 41 of 14 CFR part 21.
b. After March 20, 1997, each airplane:
i. Type certificated prior to March 29, 1995, in the commuter
category.
ii. Manufactured on or after March 20, 1997, and that was type
certificated in the normal category, and complies with the
requirements described in paragraphs 1.a.i through iii of this
appendix.
2. Background. Sections 121.157 and 121.173(b) require
that the airplanes operated under this part and described in
paragraph 1 of this appendix, comply with the Airplane Performance
Operating Limitations in §§ 121.189 through 121.197. Airplanes
described in § 121.157(f) and paragraph 1.a of this appendix must
comply on and after December 20, 2010. Airplanes described in §
121.157(e) and paragraph 1.b of this appendix must comply on and
after March 20, 1997. (Airplanes type certificated in the normal
category, and in accordance with SFAR No. 41 of 14 CFR part 21, as
described in paragraph 1.a.iv of this appendix, may not be produced
after October 17, 1991.)
3. References. Unless otherwise specified, references in
this appendix to sections of part 23 of this chapter are to those
sections of 14 CFR part 23, as amended by Amendment No. 23-45
(August 6, 1993, 58 FR 42156).
Performance
4. Interim Airplane Performance Operating
Limitations.
a. Until December 20, 2010, airplanes described in paragraph 1.a
of this appendix may continue to comply with the requirements in
subpart I of part 135 and § 135.181(a)(2) of this chapter that
apply to small, nontransport category airplanes.
b. Until March 20, 1997, airplanes described in paragraph 1.b.i
of this appendix may continue to comply with the requirements in
subpart I of part 135 of this chapter that apply to commuter
category airplanes.
5. Final Airplane Performance Operating Limitations.
a. Through an amended type certification program or a
supplemental type certification program, each airplane described in
paragraph 1.a and 1.b.ii of this appendix must be shown to comply
with the commuter category performance requirements specified in
this appendix, which are included in part 23 of this chapter. Each
new revision to a current airplane performance operating limitation
for an airplane that is or has been demonstrated to comply, must
also be approved by the Administrator. An airplane approved to the
requirements of section 1.(b) of SFAR No. 41 of 14 CFR part 21, as
described in paragraph 1.a.iv of this appendix, and that has been
demonstrated to comply with the additional requirements of section
4.(c) of SFAR No. 41 of 14 CFR part 21 and International Civil
Aviation Organization Annex 8 (available from the FAA, 800
Independence Avenue SW., Washington, DC 20591), will be considered
to be in compliance with the commuter category performance
requirements.
b. Each turbopropeller powered airplane subject to this appendix
must be demonstrated to comply with the airplane performance
operating limitation requirements of this chapter specified as
follows:
i. Section 23.45 Performance General.
ii. Section 23.51 Takeoff.
iii. Section 23.53 Takeoff speeds.
iv. Section 23.55 Accelerate stop distance.
v. Section 23.57 Takeoff path.
vi. Section 23.59 Takeoff distance and takeoff run.
vii. Section 23.61 Takeoff flight path.
viii. Section 23.65 Climb: All engines operating.
ix. Section 23.67 Climb: one engine inoperative.
x. Section 23.75 Landing.
xi. Section 23.77 Balked landing.
xii. Sections 23.1581 through 23.1589 Airplane flight manual and
approved manual material.
6. Operation. After compliance with the final airplane
performance operating limitations requirements has been
demonstrated and added to the Airplane Flight Manual performance
data of the affected airplane, that airplane must be operated in
accordance with the performance limitations of §§ 121.189 through
121.197.
