Special Conditions: Turbomeca S.A.,

Model Arriel 2S1 Turboshaft Engine

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Notice of proposed special

conditions.

SUMMARY: This notice proposes special

conditions for the Turbomeca S.A., of

Bordes, France, Model Arriel 2S1

turboshaft engine. This engine was

validated on June 10, 1996, by the FAA

and Type Certificate No. E00054EN was

issued. The engine will have an

additional new novel or unusual engine

rating. The applicable airworthiness

regulations do not contain adequate or

appropriate safety standards for this

design feature. This document contains

the additional safety standards that the

Administrator considers necessary to

establish a level of safety equivalent to

that established by existing

airworthiness standards.

DATES: Comments must be submitted on

or before May 29, 1998.

ADDRESSES: Comments on this proposal

may be mailed in duplicate to: Federal

Aviation Administration, Office of the

Background

On March 19, 1998, Turbomeca S.A.,

applied for an amendment to Type

Certificate No. E00054EN to include a

new 30-minute engine rating to Model

Arriel 2S1 turboshaft engine. The rating

is intended for use up to 30 minutes at

any time after takeoff in a flight for

performing search and rescue missions.

The Model Arriel 2S1 turboshaft engine

will be rated at 30-Second one engine

inoperative (OEI), 2-Minute OEI,

Continuous OEI, 30-Minute, Takeoff,

and Maximum Continuous ratings.

The applicable airworthiness

requirements do not contain a definition

for a ‘‘30-minute’’ power rating, and do

not contain adequate or appropriate

safety standards of this new and

unusual engine rating.

Type Certification Basis

Under the provisions of 14 CFR

21.101, Turbomeca S.A., must show that

the Model Arriel 2S1 turboshaft engine

meets the requirements of the applicable

regulations in effect on the date of the

application, or the applicable provisions

of the regulations incorporated by

reference in Type Certificate No.

E00054EN. The regulations incorporated

by reference in the type certificate are

commonly referred to as the ‘‘original

type certification basis’’. The regulations

incorporated by reference in Type

Certificate No. E00054EN are §§ 21.29

and part 33, effective February 1, 1965,

as amended by Amendments 33–1

through 33–14, and Special Conditions

SC–33–ANE–05, Docket No. 95–ANE–

46, published on April 15, 1996 (61 FR

16375).

The Administrator finds that the

applicable airworthiness regulations in

part 33, as amended, do not contain

adequate or appropriate safety standards

for the additional new engine rating for

the Model Arriel 2S1 turboshaft engine

because it is a novel or unusual engine

rating feature, special conditions are

prescribed under the provision of 14

CFR 21.16.

Special conditions, as appropriate, are

issued in accordance with 14 CFR 11.49

after public notice, as required by

§§ 11.28 and 11.29(b), and become part

of the type certification basis in

accordance with 14 CFR 21.101(b)(2).

Novel or Unusual Design Features

The Turbomeca S.A., Model Arriel

2S1 turboshaft engine will incorporate

the following novel or unusual design

features: Rated 30-minute power. The

power available for rotorcraft hovering

to perform maritime search and rescue

missions is currently limited to the

maximum continuous rating power

under current part 33. The proposed

‘‘30-minute power’’ rating would

provide higher power level than

currently available for use up to 30

minutes at any time between takeoff and

landing in one flight. This new rating

will enhance rotorcraft safety through

the availability of increased power for

hovering operations calling for greater

than maximum continuous power.

Applicability

As discussed above, these special

conditions are applicable to the

Turbomeca S.A., Model Arriel 2S1
Federal Register / Vol. 63, No. 82 /Wednesday, April 29, 1998 / Proposed Rules 23403

turboshaft engine. Should Turbomeca

S.A., of Bordes, France, apply at a later

date for a change to the type certificate

to include another model incorporating

the same or novel or unusual design

feature, the special conditions would

apply to that model as well under the

provisions of 14 CFR 21.101(a)(1).

Conclusion

This action affects only certain novel

or unusual design features on one model

of engines. It is not a rule of general

applicability and it affects only the

applicant who applied to the FAA for

approval of these features on the engine.

horsepower developed under static

conditions at specified altitudes and

temperatures within the operating

limitations established under part 33 of

this chapter, and limited in use to

periods of not over 30 minutes each.

(a) Unless already accomplished

under § 33.87(d), in addition to the

requirements of § 33.87, the following

test must be conducted:

Rated 30-minute power. Thirty

minutes at rated 30-minute power

during the twenty -five 6-hour

endurance test cycles.
