SUPPLEMENTARY INFORMATION: 

Discussion

    We received reports of unannunciated asymmetric braking during 
landing deceleration on several Honda Aircraft Company LLC Model HA-420 
airplanes. Investigation revealed that the power brake valve (PBV) 
housing design drawing dimension for a bore diameter, which serves as 
an O-ring gland outer diameter, is oversized from Society of Automotive 
Engineers (SAE) specification guidelines for O-ring gland dimensions. 
The oversized bore allows back-up ring extrusion damage during normal 
operating hydraulic pressure in the valve, O-ring deformation/damage, 
and internal leakage of hydraulic pressure within the PBV from the 
master cylinder brake lines. The damage to the back-up ring and O-ring 
worsens during operation and causes the internal leakage rate of the 
PBV brake master cylinder lines to increase over time. This condition, 
if not addressed, could result in failure of the PBV, which could cause 
degraded braking performance and reduced directional control during 
ground operations and landing deceleration. We are issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed Honda Aircraft Company Temporary Revision TR 01.1, 
dated February 16, 2018, to the Honda Aircraft Company HA-420 Airplane 
Flight Manual and Service Bulletin SB-420-32-001, dated January 8, 
2018. Temporary Revision TR 01.1, dated February 16, 2018, to the HA-
420 Airplane Flight Manual (AFM) describes procedures for performing 
pilot checks of the braking system during ground operations before 
every flight and before every landing and includes instructions for 
corrective actions if any indication of a leaking PBV is found. Service 
Bulletin SB-420-32-001, dated January 8, 2018, describes procedures for 
replacing a defective PBV with an improved design PBV. 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.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires inserting a temporary revision into the AFM, which 
may be performed by the owner/operator (pilot) holding at least a 
private pilot certificate and must be entered into the airplane records 
showing compliance with this AD in accordance with 14 CFR 43.9 (a)(1)-
(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as 
required by 14 CFR 91.417, 121.380, or 135.439. This AD also requires 
replacing the installed PBV, P/N HJ1-13243-101-005 or P/N HJ1-13243-
101-007, with an improved PBV, P/N HJ1-13243-101-009, if a defective 
PBV is detected during the required pilot checks as specified in the 
temporary revision. In addition, this AD provides an optional 
terminating action for the temporary revision into the AFM by replacing 
the installed PBV with the improved PBV, P/N HJ1-13243-101-009.

Interim Action

    We consider this AD interim action. We are currently considering 
requiring replacement of the installed PBV, P/N HJ1-13243-101-005 or P/
N HJ1-13243-101-007, with an improved part, which will constitute 
terminating action for the temporary revision to the AFM. However, the 
planned compliance time for the replacement of the PBV would allow 
enough time to provide notice and opportunity for prior comment on the 
merit of the replacement.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because failure of the PBV could cause degraded braking performance and 
reduced directional control during ground operations and landing 
deceleration. Therefore, we find good cause that notice and opportunity 
for prior public comment are impracticable. In addition, for the reason 
stated above, we find that good cause exists for making this amendment 
effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2018-
0223 and Product Identifier 2018-CE-007-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this final rule. We will 
consider all comments received by the closing date and may amend this 
final rule because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this final rule.

Costs of Compliance

    We estimate that this AD affects 72 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the pilot check of the 
braking system during ground operations before every flight and before 
every landing. We have no way of determining the number of airplanes 
that might need these replacements:

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.
    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

    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) Is not a ``significant rule'' under 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.
