We are adopting a new airworthiness directive (AD) for PILATUS AIRCRAFT LTD. Model PC-12/47E airplanes. 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 an error within the flight management system caused by installing Primus APEX software Build 10 or 10.9, which could cause deviation from the correctly calculated barometric vertical navigation nominal glide path. We are issuing this AD to require actions to address the unsafe condition on these products.

Airworthiness Directives; PILATUS AIRCRAFT LTD. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for PILATUS 
AIRCRAFT LTD. Model PC-12/47E airplanes. 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 an error within the flight management system caused by 
installing Primus APEX software Build 10 or 10.9, which could cause 
deviation from the correctly calculated barometric vertical navigation 
nominal glide path. We are issuing this AD to require actions to 
address the unsafe condition on these products.

DATES: This AD is effective July 13, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of July 13, 
2017.

SUPPLEMENTARY INFORMATION:

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. Model 
PC-12/47E airplanes. The NPRM was published in the Federal Register on 
March 21, 2017 (82 FR 14488). 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:

    An occurrence was reported of a split between the vertical 
guidance data and the flight director steering commands during a 
Vertical Glide Path (VGP) approach. Subsequent investigation 
identified an error within the Flight Management System (FMS) that 
was introduced into Primus APEX software (S/W) Build 10 and S/W 
Build 10.9.
    This condition, if not corrected, could lead to loss of control 
of the aeroplane.
    To address this potential unsafe condition, Pilatus issued 
Temporary Revision (TR) No. 38 to the PC-12/47E Pilot's Operating 
Handbook, (POH) Report No: 02277 (hereafter referred to as ``POH TR 
38'' in this AD), limiting VGP Approach mode sourced on baro 
Vertical Navigation (VNAV) to visual meteorological conditions (VMC) 
only, and providing procedures applicable in case of VGP deviation 
occurring during baro VNAV approaches.
    For the reason described above, this [EASA] AD requires 
amendment of the applicable Aircraft Flight Manual (AFM).

    The MCAI can be found in the AD docket on the Internet at https://www.regulations.gov/document?D=FAA-2017-0194-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to the comment.

Request To Clarify the Unsafe Condition

    Johan Kruger of PILATUS AIRCRAFT LTD. stated that in the Discussion 
section and the Reason section (paragraph (e)) of the proposed AD, it 
is stated that the unsafe condition may result in loss of control due 
to following incorrect data from the flight management system. The 
commenter stated that the loss of control statement may be misleading.
    The commenter further stated that the autopilot fails to follow the 
correctly indicated nominal vertical flight path. If the pilot does not 
observe the indicated vertical deviation, which is the pilot's primary 
duty during instrument meteorological conditions (IMC) final approach, 
it could result in the pilot losing situational awareness. In a worst 
case scenario, the airplane would descent towards terrain and 
ultimately, if no attention is given to terrain awareness and warning 
system (TAWS) call outs, collide with the terrain--potential controlled 
flight into terrain (CFIT).
    The commenter requested that the last sentence of paragraph (e) be 
changed to read: ``We are issuing this AD to prevent the pilot from 
following incorrect data from the flight management system, which could 
result in the loss of situational awareness.''
    We agree with the commenter and have changed the AD based on this 
comment.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously and minor editorial changes. We 
have determined that these minor changes:

[[Page 26572]]

     [Agr]re consistent with the intent that was proposed in 
the NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Related Service Information Under 1 CFR Part 51

    We reviewed PILATUS AIRCRAFT LTD. Temporary Revision No. 38 to PC-
12/47E Pilot's Operating Handbook, Airplane Flight Manual 02277, 
Section 2--Limitations, Report No: 02277, dated February 8, 2017. The 
service information describes procedures for limiting the use of the 
autopilot and flight director to day visual meteorological conditions 
(VMC) during barometric vertical navigation (baro VNAV) during a 
vertical glide path approach (VGP). This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this AD.

Costs of Compliance

    We estimate that this AD will affect 350 products of U.S. registry. 
We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $29,750, or $85 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0194; or in person at the Docket Management Facility between 9 a.m. and 
5 p.m., Monday through Friday, except Federal holidays. The AD docket 
contains the NPRM, the regulatory evaluation, any comments received, 
and other information. The street address for the Docket Office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
