Airworthiness Directives; ATR-GIE Avions de Transport 
R[eacute]gional Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42 
airplanes and Model ATR72 airplanes. This AD was prompted by reports of 
interference and chafing between a propeller brake hydraulic pipe and 
an electrical wire bundle bracket screw installed in the underwing box 
of the right-hand (RH) engine nacelle. This AD requires modification of 
the electrical wiring routing in the engine nacelles, a one-time 
detailed visual inspection (DVI) of the propeller brake hydraulic pipe 
and electrical wire bundle bracket screw head in the underwing box of 
the RH engine nacelle and, depending on findings, accomplishment of 
applicable corrective actions, as specified in a European Union 
Aviation Safety Agency (EASA) AD, which is incorporated by reference. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

reference of a certain publication listed in this AD as of May 18, 
2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0278, dated November 12, 2019 
(``EASA AD 2019-0278'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain ATR-GIE Avions de Transport R[eacute]gional Model 
ATR42-200, -300, -320, -400, and -500 airplanes and Model ATR72-101, -
102, -201, -202, -211, -212, and -212A airplanes. Model ATR42-400 
airplanes are not certified by the FAA and are not included on the U.S. 
type certificate data sheet; this AD therefore does not include those 
airplanes in the applicability.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain ATR-GIE Avions 
de Transport R[eacute]gional Model ATR42 airplanes and Model ATR72 
airplanes. The NPRM published in the Federal Register on January 17, 
2020 (85 FR 2906). The NPRM was prompted by reports of interference and 
chafing between a propeller brake hydraulic pipe and an electrical wire 
bundle bracket screw installed in the underwing box of the RH engine 
nacelle. The NPRM proposed to require modification of the electrical 
wiring routing in the engine nacelles; a one-time DVI of the propeller 
brake hydraulic pipe and electrical wire bundle bracket screw head in 
the underwing box of the RH engine nacelle; and, depending on findings, 
accomplishment of applicable corrective actions; as specified in an 
EASA AD.
    The FAA is issuing this AD to address hydraulic pipe damage, which 
could result in hydraulic leakage and a potential fire in a non-fire-
resistant area of the RH engine nacelle when the propeller brake is 
activated or deactivated while the airplane is on the ground. See the 
MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0278 describes procedures for a modification of the 
electrical wiring routing in the engine nacelles, followed by a one-
time DVI of the propeller brake hydraulic pipe and electrical wire 
bundle bracket screw head in the underwing box of the RH engine nacelle 
and, depending on findings, accomplishment of applicable corrective 
actions. Corrective actions include hydraulic pipe replacement and 
repair. This material 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.

Costs of Compliance

    The FAA estimates that this AD affects 62 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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.
    The FAA is 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

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.

bundle bracket screw installed in the underwing box of the right-
hand (RH) engine nacelle. The FAA is issuing this AD to address 
hydraulic pipe damage, which could result in hydraulic leakage and a 
potential fire in a non-fire-resistant area of the RH engine nacelle 
when the propeller brake is activated or deactivated while the 
airplane is on the ground.

to this AD.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2019-0278 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Section, send it to the attention of 
the person identified in paragraph (k) of this AD. Information may 
be emailed to: [email protected]. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or ATR-GIE Avions
