SUPPLEMENTARY INFORMATION: 

Discussion

    Honda Aircraft Company LLC has informed us that several required 
maintenance tasks driven by system safety assessment requirements were 
inadvertently omitted from or listed incorrectly in the airworthiness 
limitations section of the Honda Aircraft Company, Inc. Model HA-420 
ALIM with a revision level prior to Revision C1 and dated earlier than 
May 1, 2018. Additional airworthiness limitations, additional 
maintenance tasks for various systems, and reduced compliance times for 
existing maintenance tasks are necessary to maintain all airplanes in a 
condition for safe operation.
    In addition, we determined that some airplanes may have exceeded 
the new maintenance intervals once the ALIM was revised, including but 
not limited to:
    1. Latent failure mode of the Wing Anti-Ice Crossflow Valve 
(WAIXV): This condition would prevent the opening of the WAIXV when 
commanded and could result in loss of control of the airplane if one 
bleed air source becomes unavailable while operating in icing 
conditions. An existing ice protection system check would identify this 
condition; however, the system check was not located in the 
airworthiness limitations section of the ALIM. The revised ALIM 
relocates the system check to the airworthiness limitations section and 
reduces the system check intervals from 600 hours time-in-service (TIS) 
to 300 hours TIS.
    2. Latent failures in the brake and emergency accumulators: The 
hydraulic power system check for identifying and correcting potential 
latent failures in the brake and emergency accumulators contained 
incorrect procedures and was not located in the airworthiness 
limitations section of the ALIM. Honda corrected these procedures and 
superseded the current procedures (-801) with the new procedures (-
802). The revised ALIM lists the correct procedures for the hydraulic 
power system check and relocates this check to the airworthiness 
limitations section.
    These conditions, if not addressed, could result in failures in 
various airplane systems, including but not limited to the hydraulic 
and ice protection systems, which could result in loss of control of 
the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Honda Aircraft Company HA-420 Airworthiness Limitation 
and Inspection Manual ``Airworthiness Limitations--Inspection/Check'' 
(Airworthiness Limitations section 05-60-00), dated May 1, 2018. The 
service information contains airworthiness limitations, additional 
maintenance tasks for various

[[Page 38658]]

systems, and reduced compliance times for existing maintenance tasks, 
including but not limited to the hydraulic and ice protection systems. 
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 revising the airworthiness limitations section of 
the maintenance program by replacing Airworthiness Limitations section 
05-60-00 with an issue date earlier than May 1, 2018, with the revised 
Airworthiness Limitations section 05-60-00, dated May 1, 2018. 
Incorporating these airworthiness limitations makes them mandatory 
(reference 14 CFR 43.16 and 14 CFR 91.403(c)). For airplanes that have 
exceeded the new maintenance intervals, compliance with replacement 
times or inspection intervals is required before further flight once 
the limitations are incorporated. Operators have the compliance time 
period of the AD to plan for any immediate maintenance action required 
by the new limitations. This includes, but is not limited to the 
following:
     The 600-hour TIS ice protection system check, AMM Task 
Reference 30-10-01-700-801, previously located in the Scheduled 
Inspections section 05-20-00, has been relocated to the Airworthiness 
Limitations section 05-60-00, and reduced to a 300-hour TIS interval. 
Airplanes that have exceeded 300 hours TIS since the ice protection 
system check was last performed must have the ice protection system 
check within the compliance time specified in paragraph (f) of the AD. 
This AD allows a credit for airplanes that had the system check at the 
previous 600-hour TIS interval but have not exceeded 300 hours TIS 
since the last check and the WAIXV passed the functionality check 
contained in the procedure.
     The 600-hour TIS hydraulic power system check, AMM Task 
Reference 29-00-01-700-801, previously located in the Scheduled 
Inspections section 05-20-00, has been relocated to the Airworthiness 
Limitations section 05-60-00, and revised to AMM Task Reference 29-00-
01-700-802. Airplanes that had the system check per the previous 
incorrect version of the maintenance task (29-00-01-700-801) at 600 
hours TIS must have the inspection done before further flight after 
incorporating the airworthiness limitations.

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 exceeding certain maintenance intervals and/or limitations 
could cause failures in various airplane systems, including but not 
limited to the hydraulic and ice protection systems, which could result 
in loss of control. Therefore, we find good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reasons 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-
0688 and Product Identifier 2018-CE-026-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 96 airplanes of U.S. registry.
    We estimate 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.
    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

[[Page 38659]]

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.
