14 CFR Parts 27 and 29 

Interest in Restructure of Rotorcraft 

Airworthiness Standards 

ACTION: Notice of Disposition of 

Comments. 

SUMMARY: This notice disposes of public 

comments received by the Federal 

Aviation Administration (FAA) in 

response to a Federal Register notice 

published on February 22, 2013, 

requesting comments on a potential 

restructuring of the rotorcraft 

airworthiness standards of Title 14 of 

the Code of Federal Regulations (14 

CFR) parts 27 (normal category 

rotorcraft) and 29 (transport category 

rotorcraft). Specifically, the agency 

sought comments on the necessity of 

updates to parts 27 and 29, including 

whether to change the existing weightand seat-based applicability standards 

for normal and transport rotorcraft. 

Based on the comments received, the 

FAA is terminating this docket. 

Commenters indicated a substantial 

interest in revising or restructuring the 

certification standards for parts 27 and 

29, and the FAA’s Rotorcraft Directorate 

will begin establishing the appropriate 

forums to involve interested parties. 

DATES: The docket is terminated as of 

July 31, 2014.

SUPPLEMENTARY INFORMATION: 

Background and Discussion 

Currently, rotorcraft with a maximum 

weight of 7,000 pounds or less and nine 

passenger seats or less are certificated as 

normal category rotorcraft under part 

27; rotorcraft with a maximum weight 

greater than 7,000 pounds or with 10 or 

more passenger seats are certificated as 

transport category rotorcraft under part 

29. 

The FAA and rotorcraft industry have 

discussed potential revisions to the 

‘‘applicability’’ rules for rotorcraft 

certificated under parts 27 and 29 since 

the early 1990s. In February 1994, the 

FAA held a public meeting to determine 

a course of action in the best interest of 

the public and the aviation community. 

An Aviation Rulemaking Advisory 

Committee working group was 

established with representatives from 

the FAA, the Joint Aviation Authorities, 

and Transport Canada Civil Aviation, as 

well as from U.S. and European 

helicopter manufacturers. In February 

1995, the committee established the 

Rotorcraft Gross Weight and Passenger 

Issues Working Group, and tasked the 

group with recommending new or 

revised requirements for increasing the 

gross weight and passenger limitations 

for normal category rotorcraft. There 

was agreement within the group to 

increase the gross weight limitation of 

part 27 from 6,000 to 7,000 pounds with 

added passenger safety requirements. 

The FAA implemented this regulatory 

change in a 1999 final rule (64 FR 

45092, August 18, 1999). 

We continue to recognize that the 

evolution of parts 27 and 29 has not 

kept pace with technology and the 

capability of rotorcraft produced 

currently. The FAA is therefore 

interested in investigating new 

approaches that would make the 

rotorcraft airworthiness regulations 

more efficient and adaptable to future 

technology. Additionally, the FAA has 

found that, without a rulemaking effort 

to extensively revise the rotorcraft 

standards, we are left with the option of 

issuing multiple special conditions for 

the same technologies. 

The FAA published a Federal 

Register notice on February 22, 2013 (78 

FR 12254), requesting comments on 

‘‘Interest in Restructure of Rotorcraft 

Airworthiness Standards.’’ Specifically, 

we requested comment on (1) to what 

extent commenters believed the 

certification standards need to be 

changed in order to remain relevant; (2) 

whether the current standards need to 

be completely changed, as opposed to 

more targeted changes; (3) whether the 

applicability rules should be changed 

from weight- and passenger-based 

standards, and, if so, how; and (4) 

commenters’ willingness to participate 

in a rulemaking committee. We received 

48 comments to the docket number 

FAA–2013–0144. 

Comments Summary 

Of the 48 comments received, the 

majority were from operators and their 

affiliates. There were also comments 

from another civil aviation authority 

(Transport Canada Civil Aviation); 

various rotorcraft-affiliated 

organizations (including the Aerospace 

Industries Association, the American 

Helicopter Society International, the 

Association of Air Medical Services, the 

General Aviation Manufacturers 

Association, and Helicopter Association 

International); vendors and 

manufacturers (including Bell 

Helicopter, Eurocopter, and Marenco 

Swisshelicopter); and others. These 

comments indicated a substantial 

interest in favor of some form of 

revision or restructure of the rotorcraft 

design certification standards in parts 

27 and 29 and expressed that the 

current regulatory scheme is outdated 

by technology and impedes the 

development of new rotorcraft models. 

Only three commenters stated the 

weight and passenger thresholds of the 

current regulations should remain 

unchanged. Most commenters 

recommended that the FAA approach 

this effort in a deliberate and 

methodical manner, including forming a 

group in coordination with industry to 

evaluate parts 27 and 29 and provide 

recommendations to the FAA prior to 

initiating a formal rulemaking action. 

Commenters also expressed a need to 

coordinate this effort with other civil 

aviation authorities. Additionally, many 

commenters expressed interest in 

participating in the process of updating 

the regulations. 

Termination of This Docket and Future 

Agency Action 

Based on these comments, the FAA 

has determined that there is sufficient 

interest in the rotorcraft community to 

pursue further collaboration towards 

possible revisions to parts 27 and 29. 

The FAA is therefore terminating this 

docket. The Rotorcraft Directorate will 

begin establishing the appropriate 

forum(s) and involving interested 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 147 / Thursday, July 31, 2014 / Proposed Rules 44321 

parties. The FAA will also reach out to 

our bilateral partners (i.e., Transport 

Canada Civil Aviation and the European 

Aviation Safety Agency) and invite their 

participation in this effort. Parties 

interested in this initiative may look 

forward to future public announcements 

on upcoming developments.

14 CFR Part 33 

[Docket No.FAA–2014–0376; Notice No. 33– 

14–01–SC] 

Special Conditions: SNECMA, 

Silvercrest-2 SC–2D; Rated 10-Minute 

One Engine Inoperative Takeoff Thrust 

at High Ambient Temperature 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed special 

conditions. 

SUMMARY: This action proposes special 

conditions for the SNECMA, Silvercrest2 SC–2D engine model. This engine will 

have a novel or unusual design 

feature—an additional takeoff rating that 

increases the exhaust gas temperature 

(EGT) limit to maintain takeoff thrust in 

certain high ambient temperature 

conditions with one engine inoperative 

(OEI) for a maximum of 10 minutes. The 

applicable airworthiness regulations do 

not contain adequate or appropriate 

safety standards for this design feature. 

The proposed 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.

submit only one time. 

We will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, we will consider 

comments filed late if it is possible to

Background 

On April 19, 2011, SNECMA applied 

for a new type certificate (TC) for the 

Silvercrest-2 SC–2D engine model. On 

April 30, 2014, SNECMA requested an 

extension to their original TC 

application, which the FAA granted 

through June 30, 2015. 

For their Silvercrest-2 SC–2D engine 

model, SNECMA requests an additional 

takeoff rating to maintain takeoff thrust 

in certain high ambient temperature 

conditions with OEI. Therefore, the 

Silvercrest-2 SC–2D engine model 

would have two different takeoff ratings. 

The first rating corresponds with the 

rated takeoff thrust of the engine. The 

second takeoff rating maintains the 

takeoff thrust in certain high ambient 

temperature conditions for a maximum 

of 10 minutes. This additional takeoff 

rating is named, ‘‘Rated 10-Minute OEI 

Takeoff Thrust at High Ambient 

Temperature’’ (Rated 10-minute OEI 

TOTHAT). 

These special conditions are 

necessary because the applicable 

airworthiness regulations do not contain 

adequate or appropriate safety standards 

for the additional takeoff rating. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.17, 

SNECMA must show that the 

Silvercrest-2 SC–2D meets the 

applicable provisions of the applicable 

regulations in effect on the date of 

application, except as detailed in 

paragraphs 21.101(b) and (c). The FAA 

has determined the following 

certification basis for the Silvercrest-2 

SC–2D engine model: 

1. 14 CFR part 33, ‘‘Airworthiness 

Standards Aircraft Engines,’’ dated 

February 1, 1965, with Amendments 

33–1 through 33–31, dated July 18, 

2011. 

If the FAA finds that the regulations 

in effect on the date of the application 

for the change do not provide adequate 

or appropriate safety standards for the
