14 CFR Part 27
[Docket No. FAA-2012-0820; Special Conditions No. 27-028-SC]
Special Conditions: Eurocopter France, EC130T2; Use of 30-Minute
Power Rating
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions; request for comments.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for the Eurocopter France
Model EC130T2 helicopter. This model helicopter will have the novel or
unusual design feature of a 30-minute power rating, generally intended
to be used for hovering at increased power for search and rescue
missions. 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: The effective date of these special conditions is July 30, 2012.
We must receive your comments by September 27, 2012.

SUPPLEMENTARY INFORMATION:
Reason for No Prior Notice and Comment Before Adoption
The FAA has determined that notice and opportunity for public
comment are impractical because we do not expect substantive comments,
and because this special condition only affects this one manufacturer.
We also considered that these procedures would significantly delay the
issuance of the design approval, and thus, the delivery of the affected
aircraft. As certification for the Eurocopter France model EC130T2 is
imminent, the FAA finds that good cause exists for making these special
conditions effective upon issuance.
Comments Invited
While we did not precede this with a notice of proposed special
conditions, we invite interested people to take part in this rulemaking
by sending written
[[Page 48059]]
comments, data, or views. The most helpful comments reference a
specific portion of the special conditions, explain the reason for any
recommended change, and include supporting data.
We will consider all comments we receive by the closing date for
comments. We will consider comments filed late if it is possible to do
so without incurring expense or delay. We may change these special
conditions based on the comments we receive.
Background and Discussion
On October 7, 2008, Eurocopter France applied to amend Type
Certificate No. H9EU to include the new EC130T2 model. The EC130T2
model is a derivative of the EC130B4, which is currently approved under
Type Certificate No. H9EU. The EC130T2 is a 14 CFR part 27 normal
category, single-engine rotorcraft, which will be certificated for
single-pilot operation and a maximum of seven passengers. This model
includes increased performance from the Turbomeca Arriel 2D engine, an
upgraded main transmission, new vehicle engine management display
(VEMD) avionics, and an active vibration control system.
Eurocopter France proposes that the EC130T2 model use a novel and
unusual design feature, which is a 30-minute power rating, identified
in the Arriel 2D engine type certification data sheet (TCDS) [FAA
Turbomeca TCDS No. E00054EN]. 14 CFR 1.1 defines ``rated takeoff
power'' as limited in use to no more than 5 minutes for takeoff
operation. Thus, the use of takeoff power for 30 minutes will require
special airworthiness standards, known as special conditions, to
address the use of this 30-minute power rating and its effects on the
rotorcraft. These special conditions will add requirements to the
existing airworthiness standards in 14 CFR 27.923 (Rotor drive system
and control mechanism tests), Sec. 27.1305 (Powerplant instruments),
and Sec. 27.1521 (Powerplant limitations).
For the EC130T2, the European Aviation Safety Agency (EASA) has
issued CRI E-02, which documents the special conditions.
The following is a summary of the final special conditions:
In addition to the requirements of Section 27.923, Rotor Drive
System and Control Mechanism Tests, the aircraft drive-system effects
due to use of the 30-minute power rating versus the Takeoff (5-minute)
rating must be accounted for in the rotor drive-system testing.
In addition to the requirements of Section 27.1305, Powerplant
Instruments, since this new 30-minute power rating has a time limit
associated with its use, the pilot must have the means to identify:
When the rated engine power level is achieved,
When the event begins, and
When the time interval expires.
In addition to the requirements of Section 27.1521, Powerplant
Limitations, a new 30-minute rating must be defined for the use of
takeoff power for greater than 5 minutes and must be limited to no more
than 30 minutes per use.
Furthermore, the Model EC130T2 rotorcraft flight manual must
include limitations on use of the 30-minute power rating to state:
Continuous use above MCP is limited to 30 minutes, and
Cumulative use above MCP is limited to 1 hour per flight.
Type Certification Basis
Under 14 CFR 21.101, Eurocopter France must show that the EC130T2
model helicopter meets the applicable provisions of the regulations
incorporated by reference in Type Certificate No. H9EU, or the
applicable regulations in effect on the date of application for the
amendment to the type certificate. 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 H9EU are as follows:
(a) 14 CFR 21.29, and part 27 Amendments 27-1 through 27-32, except
14 CFR 27.952 is not adopted.
(b) 14 CFR Part 36 Appendix H through Amendment 20
(c) Special Condition 27-009-SC for HIRF
(d) Equivalent Level of Safety Findings issued against:
(1) 14 CFR 27.1549(b) Powerplant Instrument Markings.
(2) 14 CFR 27.1027(b)(2) Main Gearbox Oil Filter Bypass
The Administrator has determined that the applicable airworthiness
regulations (that is, 14 CFR part 27) do not contain adequate or
appropriate safety standards for the EC130T2 model helicopter because
of a novel or unusual design feature. Therefore, special conditions are
prescribed under the provisions of 14 CFR 21.16.
The FAA issues special conditions, as defined by 14 CFR 11.19, in
accordance with 14 CFR 11.38, and they become part of the type
certification basis under Sec. 21.101.
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 novel or
unusual design feature, or should any other model already included on
the same type certificate be modified to incorporate the same novel or
unusual design feature, the special conditions would also apply to the
other model.
Novel or Unusual Design Features
The EC130T2 model helicopter will incorporate a novel or unusual
design feature, which is:
A 30-minute power rating.
Applicability
These special conditions are applicable to the Eurocopter France
Model EC130T2 helicopter. These special conditions would apply if
Eurocopter France seeks to amend Type Certificate No. H9EU to add
another model that has the same unusual design feature.
Conclusion
This action affects only certain novel or unusual design features
on the Eurocopter France Model EC130T2 helicopter. It is not a rule of
general applicability, and it affects only the applicant who applied to
the FAA for approval of this feature.

The Special Conditions
0
Accordingly, pursuant to the authority delegated to me by the
Administrator, the following special conditions are issued as part of
the type certification basis for Eurocopter France model EC130T2
helicopter. Unless stated otherwise, all requirements in Sec. Sec.
27.923, 27.1305 and 27.1521 remain unchanged.
(a) Section 27.923 Rotor drive system and control mechanism tests,
at Amendment 27-29. In addition to the requirements of this section,
the test prescribed in Sec. 27.923(e) must be conducted in intervals
of not less than 30 minutes.
(b) Section 27.1305 Powerplant instruments, at Amendment 27-37. In
addition to the requirements of this section, a means must be provided
to indicate to the pilot when the engine is at the 30-minute power
level, when the event begins, and when the time interval expires.
(c) Section 27.1521 Powerplant limitations, at Amendment 27-29. In
[[Page 48060]]
addition to the requirements of this section, use of the 30-minute
power must be limited to no more than 30 minutes per use, and no more
than one hour per flight. The use of the 30-minute power must also be
limited by:
(1) The maximum rotational speed, which may not be greater than--
(i) The maximum value determined by the rotor design; or
(ii) The maximum value demonstrated during the type tests;
(2) The maximum allowable gas temperature; and
(3) The maximum allowable torque.
