SUPPLEMENTARY INFORMATION: jstallworth on DSK7TPTVN1PROD with RULES SUMMARY: Background On December 15, 2011, BHTI applied for a type certificate for a new transport category helicopter designated as the Model 525. The aircraft is a medium twin-engine rotorcraft. The design maximum takeoff weight is 20,000 pounds, with a maximum capacity of 16 passengers and a crew of 2. VerDate Sep<11>2014 14:34 Nov 08, 2016 Jkt 241001 BHTI proposes that the Model 525 use a novel and unusual design feature, which is an electronic CAS. Section 29.1322 of Title 14, Code of Federal Regulations (14 CFR), prescribes discrete colored lights for warning, caution, and advisory alerts. In this regard, § 29.1322 lacks adequate airworthiness standards for alerting messages and displays that do not use discrete colored lights, that include nonvisual cues, that provide alerting information to the flightcrew, and that use integrated and multiple alerts concurrently. The Model 525 CAS will have more effective integrated visual, aural, tactile, and alert messaging that will require special airworthiness standards, known as special conditions, to address crew alerting of failures or malfunctions in critical systems. These special conditions will add requirements from the airworthiness standards in § 25.1322 (Amendment 25–131) for advanced crew alerting systems in transport category aircraft. unusual design features: An advanced CAS system. The novel design includes the integration of audio and visual alerts, tactical sensors, and CAS message consolidation. The new technologies associated with integrated visual, aural, tactile, and alert messaging are more effective in alerting the flightcrew and aiding them in decisionmaking than the discrete colored lights for warning, caution, and advisory alerts prescribed in § 29.1322 alone. Discussion The current 14 CFR part 29 standards do not provide adequate standards for the advanced CAS system of the Bell Model 525 helicopter due to the complexity of the aircraft systems and the modes of the fly-by-wire primary flight controls. The special condition will update definitions, define a prioritization scheme, expand color requirements, and address performance for flightcrew alerting to reflect changes in technology and functionality. Comments A notice of proposed special conditions for the BHTI Model 525 helicopter CAS was published in the Federal Register on June 3, 2016 (81 FR 35654). We did not receive any comments. Type Certification Basis Under the provisions of 14 CFR 21.17, BHTI must show that the Model 525 meets the applicable provisions of part 29, as amended by Amendments 29–1 through 29–55 thereto. The BHTI Model 525 certification basis date is December 15, 2011, the date of application to the FAA. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 29) do not contain adequate or appropriate safety standards for the BHTI Model 525 because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same or similar novel or unusual design feature, the special conditions would also apply to the other model under § 21.101. The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with § 11.38, and they become part of the type-certification basis under § 21.17(a)(2). Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

525 Helicopters; Crew Alerting System (CAS)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions.

-----------------------------------------------------------------------

SUMMARY: These special conditions are issued for the BHTI Model 525 
helicopter. This helicopter will have a novel or unusual design feature 
associated with the electronic CAS. The applicable airworthiness 
regulations do not contain adequate or appropriate safety standards for 
this design feature. These special conditions contain the additional 
safety standards that the Administrator considers necessary to 
establish a level of safety equivalent to that established by the 
existing airworthiness standards.

DATES: These special conditions are effective December 9, 2016.

SUPPLEMENTARY INFORMATION: 

Background

    On December 15, 2011, BHTI applied for a type certificate for a new 
transport category helicopter designated as the Model 525. The aircraft 
is a medium twin-engine rotorcraft. The design maximum takeoff weight 
is 20,000 pounds, with a maximum capacity of 16 passengers and a crew 
of 2.
    BHTI proposes that the Model 525 use a novel and unusual design 
feature, which is an electronic CAS. Section 29.1322 of Title 14, Code 
of Federal Regulations (14 CFR), prescribes discrete colored lights for 
warning, caution, and advisory alerts. In this regard, Sec.  29.1322 
lacks adequate airworthiness standards for alerting messages and 
displays that do not use discrete colored lights, that include non-
visual cues, that provide alerting information to the flightcrew, and 
that use integrated and multiple alerts concurrently.
    The Model 525 CAS will have more effective integrated visual, 
aural, tactile, and alert messaging that will require special 
airworthiness standards, known as special conditions, to address crew 
alerting of failures or malfunctions in critical systems. These special 
conditions will add requirements from the airworthiness standards in 
Sec.  25.1322 (Amendment 25-131) for advanced crew alerting systems in 
transport category aircraft.

Type Certification Basis

    Under the provisions of 14 CFR 21.17, BHTI must show that the Model 
525 meets the applicable provisions of part 29, as amended by 
Amendments 29-1 through 29-55 thereto. The BHTI Model 525 certification 
basis date is December 15, 2011, the date of application to the FAA.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 29) do not contain adequate or 
appropriate safety standards for the BHTI Model 525 because of a novel 
or unusual design feature, special conditions are prescribed under the 
provisions of Sec.  21.16.
    Special conditions are initially applicable to the model for which 
they are issued. Should the type certificate for that model be amended 
later to include any other model that incorporates the same or similar 
novel or unusual design feature, the special conditions would also 
apply to the other model under Sec.  21.101.
    The FAA issues special conditions, as defined in 14 CFR 11.19, in 
accordance with Sec.  11.38, and they become part of the type-
certification basis under Sec.  21.17(a)(2).

Novel or Unusual Design Features

    The BHTI Model 525 helicopter will incorporate the following novel 
or unusual design features: An advanced CAS system. The novel design 
includes the integration of audio and visual alerts, tactical sensors, 
and CAS message consolidation. The new technologies associated with 
integrated visual, aural, tactile, and alert messaging are more 
effective in alerting the flightcrew and aiding them in decision-making 
than the discrete colored lights for warning, caution, and advisory 
alerts prescribed in Sec.  29.1322 alone.

Discussion

    The current 14 CFR part 29 standards do not provide adequate 
standards for the advanced CAS system of the Bell Model 525 helicopter 
due to the complexity of the aircraft systems and the modes of the fly-
by-wire primary flight controls. The special condition will update 
definitions, define a prioritization scheme, expand color requirements, 
and address performance for flightcrew alerting to reflect changes in 
technology and functionality.

Comments

    A notice of proposed special conditions for the BHTI Model 525 
helicopter CAS was published in the Federal Register on June 3, 2016 
(81 FR 35654). We did not receive any comments.

Applicability

    As discussed above, these special conditions are applicable to the 
BHTI Model 525 helicopter. Should BHTI apply at a later date for a 
change to the type certificate to include another model incorporating 
the same novel or unusual design feature, the special conditions would 
apply to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
on one model of helicopter. It is not a rule of general applicability.

monochromatic displays that are not capable of conforming to the color 
convention in paragraph (e)(1) of these special conditions.
    (f) Use of the colors red, amber, and yellow in the cockpit for 
functions other than flightcrew alerting must be limited and must not 
adversely affect flightcrew alerting.
