T00003NY, or the applicable regulations in effect on the date of application for the change, except for earlier amendments as agreed upon by the FAA. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the BD–700–2A12 and BD–700– 2A13 airplanes 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 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, these special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, the Model BD–700–2A12 and BD–700–2A13 airplanes must comply with the fuel-vent and exhaustemission requirements of 14 CFR part 34, and the noise certification requirements of 14 CFR part 36. 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 § 21.101. asabaliauskas on DSK3SPTVN1PROD with RULES Novel or Unusual Design Features The Bombardier Inc. Model BD–700– 2A12 and BD–700–2A13 airplanes will have a novel or unusual design feature associated with sidestick controllers designed to be operated with only one hand. Discussion The Bombardier Aerospace Model BD–700–2A12 and BD–700–2A13 airplanes are equipped with sidestick controllers instead of the conventional wheel or control stick. This controller is designed to be operated using only one hand. The requirements of § 25.397(c), which define limit pilot forces and torques for conventional wheel or stick controls, are not adequate for sidestick controllers because pilot forces are applied to sidestick controllers with only the wrist, not arms. Special conditions are necessary to specify the appropriate loading conditions for sidestick controllers. These special conditions contain the additional safety standards that the VerDate Sep<11>2014 16:43 Aug 31, 2016 Jkt 238001 Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. Applicability As discussed above, these special conditions are applicable to the Model BD–700–2A12 and BD–700–2A13 airplanes. Should Bombardier apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, these special conditions would apply to the other model as well. Conclusion This action affects only certain novel or unusual design features on two model series of airplanes. It is not a rule of general applicability. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, the FAA has determined that prior public notice and comment are unnecessary, and good cause exists for adopting these special conditions upon publication in the Federal Register.

Sole reliance on such a coating, without windshield wipers, constitutes a novel or unusual design feature for which the applicable airworthiness regulations do not contain adequate or appropriate safety standards. Discussion 14 CFR 25.773(b)(1) requires a means to maintain a sufficiently clear portion of the windshield for both pilots to have an extensive view along the flight path during precipitation conditions. The regulations require this means to maintain such an area during precipitation in heavy rain at speeds up to 1.5 VSR1. Hydrophobic windshield coatings may depend to some degree on airflow to maintain a clear vision area. The heavy rain and high speed conditions specified in the current rule do not necessarily represent the limiting condition for this new technology. For example, airflow over the windshield, which may be necessary to remove moisture from the windshield, may not be adequate to maintain a sufficiently clear area of the windshield in lowspeed flight or during surface operations. Alternatively, airflow over the windshield may be disturbed during such critical times as the approach to land, where the airplane is at a higherthan-normal pitch attitude.

Models PC– 12, PC–12/45, PC–12/47, and PC–12/ 47E airplanes installed with an affected engine mounting frame assembly. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as longitudinal material separation on the internal surface of the engine mounting frame assembly tubes. We are issuing this AD to detect and correct this condition, which could lead to partial or complete failure of the structural joint and possibly result in inflight detachment of the engine with consequent loss of control. DATES: This AD is effective October 6, 2016. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of October 6, 2016.

Piccola, Jr., Acting Manager, Transport Airplane Directorate, Aircraft Certification Service. 60243 PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to PILATUS AIRCRAFT LTD. Models PC–12, PC–12/45, PC–12/47, and PC–12/47E airplanes installed with an affected engine mounting frame assembly. The NPRM was published in the Federal Register on June 13, 2016 (81 FR 38115). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: The PC–12 Engine Mounting Frame Assembly (hereafter referred to as ‘‘EMF’’ in this AD), Part Number (P/N) 571.20.12.036, is a welded structure including three special tubes, P/N 571.20.12.073, P/N 571.20.12.074 and P/N 571.20.12.107, the ends of which are subject to a special swaging process during manufacturing. Longitudinal material separation on the internal surface of the special tubes was detected on few EMFs on new production aeroplanes. Investigations identified the root cause to be an incorrect accomplishment of the swaging process. This condition, if not detected and corrected, could lead to growth of the material separation and subsequent partial or complete failure of the structural joint, possibly resulting in in-flight detachment of the engine and consequent reduced control, or loss of control, of the aeroplane. To address this potential unsafe condition, Pilatus issued Service Bulletin (SB) No. 71– 009, now at Revision 2 (hereafter referred to as ‘‘the SB’’ in this AD), to provide inspection instructions for the affected EMF to detect indications of material separation. For the reason described above, this AD requires identification and inspection of the affected EMF and, depending on the findings, their replacement with serviceable EMF. The MCAI can be found in the AD docket on the Internet at: https:// www.regulations.gov/ document?D=FAA-2016-7048-0002. E:\FR\FM\01SER1.SGM 01SER1

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite interested people to take part in this rulemaking by
sending written 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 on or before the closing
date for comments. We may change these special conditions based on the
comments we receive.

Background

On May 30, 2012, Bombardier applied for an amendment to type
certificate no. T00003NY to include the new Model BD-700-2A12 and BD-
700-2A13 airplanes. These airplanes are derivatives of the Model BD-700
series of airplanes currently approved under type certificate no.
T00003NY, and are marketed as the Bombardier Global 7000 (Model BD-700-
2A12) and Global 8000 (Model BD-700-2A13). These airplanes are ultra-
long-range, executive-interior business jets.

Type Certification Basis

Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, Bombardier must show that the Model BD-700-2A12 and BD-
700-2A13 airplanes meet the applicable provisions of the regulations
listed in type certificate no. T00003NY, or the applicable regulations
in effect on the date of application for the change, except for earlier
amendments as agreed upon by the FAA.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the BD-700-2A12 and BD-700-2A13
airplanes 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 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, these special conditions would also apply to
the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the Model BD-700-2A12 and BD-700-2A13 airplanes must comply
with the fuel-vent and exhaust-emission requirements of 14 CFR part 34,
and the noise certification requirements of 14 CFR part 36.
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. 21.101.

Novel or Unusual Design Features

The Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes will
have a novel or unusual design feature associated with flightdeck
design, which incorporates a hydrophobic windshield coating to provide
adequate pilot compartment view in the presence of precipitation. Sole
reliance on such a coating, without windshield wipers, constitutes a
novel or unusual design feature for which the applicable airworthiness
regulations do not contain adequate or appropriate safety standards.

Discussion

14 CFR 25.773(b)(1) requires a means to maintain a sufficiently
clear portion of the windshield for both pilots to have an extensive
view along the flight path during precipitation conditions. The
regulations require this means to maintain such an area during
precipitation in heavy rain at speeds up to 1.5 VSR1.
Hydrophobic windshield coatings may depend to some degree on airflow to
maintain a clear vision area. The heavy rain and high speed conditions
specified in the current rule do not necessarily represent the limiting
condition for this new technology. For example, airflow over the
windshield, which may be necessary to remove moisture from the
windshield, may not be adequate to maintain a sufficiently clear area
of the windshield in low-speed flight or during surface operations.
Alternatively, airflow over the windshield may be disturbed during such
critical times as the approach to land, where the airplane is at a
higher-than-normal pitch attitude. In these cases, areas of airflow
disturbance or separation on the windshield could cause a failure to
maintain a clear vision area on the windshield.
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.

Applicability

As discussed above, these special conditions are applicable to the
Model BD-700-2A12 and BD-700-2A13 airplanes. Should Bombardier apply at
a later date for a change to the type certificate to include another
model incorporating the same novel or unusual design feature, these
special conditions would apply to the other model as well.

Conclusion

This action affects only certain novel or unusual design features
on two

[[Page 60243]]

model series of airplanes. It is not a rule of general applicability.
The substance of these special conditions has been subjected to the
notice and comment period in several prior instances and has been
derived without substantive change from those previously issued. It is
unlikely that prior public comment would result in a significant change
from the substance contained herein. Therefore, the FAA has determined
that prior public notice and comment are unnecessary, and good cause
exists for adopting these special conditions upon publication in the
Federal Register. The FAA is requesting comments to allow interested
persons to submit views that may not have been submitted in response to
the prior opportunities for comment described above.
