Airworthiness Directives; Pilatus Aircraft Limited 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 Limited Model PC-7 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 the brakes remaining activated after release of the brake 
pedal. We are issuing this AD to require actions to address the unsafe 
condition on these products.

DATES: This AD is effective April 12, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 12, 
2018.

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 Limited 
Model PC-7 airplanes. The NPRM was published in the Federal Register on 
November 21, 2017 (82 FR 55332). 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:

    This [FOCA] Airworthiness Directive (AD) is prompted due to a 
report where the brakes have remained activated after release of the 
brake pedals before taxing.
    Such a condition, if left uncorrected, could lead to an 
asymmetric braking and subsequent loss of directional control.
    In order to correct and control the situation, this [FOCA] AD 
requires the modification of the brake-pedal interconnecting tie-rod 
by removing the bonding straps and attachment hardware currently 
installed on the left and right brake-pedal interconnecting tie-
rods.

The MCAI can be found in the AD docket on the internet at: https://www.regulations.gov/document?D=FAA-2017-1079-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are 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.

Related Service Information Under 1 CFR Part 51

    We reviewed Pilatus Service Bulletin No. 32-028, dated September 
20, 2017. The service bulletin describes procedures for removing the 
left and right brake pedal interconnecting tie rods. 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 the AD.

Costs of Compliance

    We estimate that this AD will affect 18 products of U.S. registry. 
We also estimate that it would take about 2.5 work-hours 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 the AD on U.S. 
operators to be $3,825, or $212.50 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

[[Page 9796]]

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

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.

    You may examine the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
1079; or in person at Docket Operations between 9 a.m. and 5 p.m.,

2. The FAA amends Sec.  39.13 by adding the following new AD:

2018-04-10 Pilatus Aircraft Limited: Amendment 39-19206; Docket No. 
FAA-2017-1079; Product Identifier 2017-CE-039-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective April 12, 
2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pilatus Aircraft Limited Model PC-7 
airplanes, manufacturer serial numbers 101 through 618, certificated 
in any category.

(d) Subject

Gear.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated 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 the brakes 
remaining activated after release of the brake pedal. We are issuing 
this AD to prevent the brakes from remaining activated after the 
brake pedal has been released, which could lead to asymmetric 
braking and subsequent loss of control.

(f) Actions and Compliance

    Unless already done, within the next 90 days after the effective 
date of this AD, modify the brake pedal interconnecting tie rods by 
removing the bonding straps and attachment hardware following 
sections A, B, and C of the Accomplishment Instructions in Pilatus 
Service Bulletin 32-028, dated September 20, 2017.
