AD 2018-11-05

We are superseding Airworthiness Directive (AD) 2018-06-10 for certain Honda Aircraft Company LLC Model HA-420 airplanes. AD 2018-06- 10 required incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves upon condition. This AD retains the actions required in AD 2018-06-10 and adds airplanes to the Applicability section. This AD was prompted by an inadvertent mistake in the serial number applicability (both in the service bulletin and in the AD). We are issuing this AD to address the unsafe condition on these products by correcting the inadvertent serial number error.

Final rule; request for comments.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2018-06-10, Amendment 39-19230 (83 FR 13401, March 29, 2018) and adding the following new AD:

2018-11-05 Honda Aircraft Company LLC: Amendment 39-19293; Docket No. FAA-2018-0463; Product Identifier 2018-CE-021-AD.

(a) Effective Date

This AD is effective May 29, 2018.

(b) Affected ADs

This AD replaces AD 2018-06-10, Amendment 39-19230 (83 FR 13401, March 29, 2018), (``AD 2018-06-10'').

(c) Applicability

This AD applies to Honda Aircraft Company LLC Model HA-420 airplanes, serial numbers 42000011through 42000089, that:
(1) have power brake valve, part number (P/N) HJ1-13243-101-005 or HJ1-13243-101-007, installed; and
(2) are certificated in any category.

(d) Subject

Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 32, Landing Gear.

(g) Insert Temporary Revision Into the Airplane Flight Manual (AFM)

Before further flight after May 29, 2018 (the effective date ofthis AD) insert Honda Aircraft Company Temporary Revision TR 01.1, dated February 16, 2018, into the Honda Aircraft Company (Honda) HA- 420 Airplane Flight Manual (AFM) (``the temporary revision''). This insertion and the steps therein 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.

(h) Replace the Power Brake Valve (PBV)

As of and any time after May 29, 2018 (the effective date of this AD), if any of the procedures listed in the temporary revision referenced in paragraph (g) of this AD reveal a leaking PBV, before further flight, replace the PBV, P/N HJ1-13243-101-005 or P/N HJ1- 13243-101-007, with the improved design PBV, P/N HJ1-13243-101-009. Do the replacement using the Accomplishment Instructions ineither Honda Service Bulletin SB-420-32-001, dated January 8, 2018, or Revision B, dated April 16, 2018. Before further flight after installing P/N HJ1-13243-101-009, remove the temporary revision from the Honda HA-420 AFM.

(i) No Reporting Requirement

Although Honda Service Bulletin SB-420-32-001, dated January 8, 2018, and Revision B, dated April 16, 2018, specify submitting certain information to the manufacturer, this AD does not require that action.

(j) Optional Terminating Action for Inserting the AFM Temporary Revision/Pilot Checks

(1) Instead of inserting the temporary revision or at any time after inserting the temporary revision required by paragraph (g) of this AD, you may replace the installed PBV, P/N HJ1-13243-101-005 or P/N HJ1-13243-101-007, with the improved design PBV, P/N HJ1-13243- 101-009. The replacement must be done using the Accomplishment Instructions in either Honda Service Bulletin SB-420-32-001, dated January 8, 2018, or Revision B, dated April 16, 2018. Before further flight after installing P/N HJ1-13243-101-009, remove the temporary revision from the Honda HA-420 AFM.
(2) If you choose to follow the temporary revision required by paragraph (g) of this AD instead of the optional replacement in paragraph (j)(1) of this AD, the on-condition replacement required by paragraph (h) of this AD is still required before further flight.

(k) Special Flight Permit

Special flight permits for this AD are prohibited.

(l) Alternative Methods of Compliance (AMOCs)

(1) The Manager, Atlanta ACO 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 manager of the certification office, send it to the attention of the person identified in paragraph (m) of this AD.
(2) 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.
(3) For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (l)(3)(i) and (ii) of this AD apply.
(i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with this AD. An AMOC is required for any deviations to RC steps, including substeps and identified figures.
(ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.

Discussion

We issued AD 2018-06-10, Amendment 39-19230 (83 FR 13401, March 29, 2018), (``AD 2018-06-10''), for certain Honda Aircraft Company LLC Model HA-420 airplanes. AD 2018-06-10 required incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves upon condition. AD 2018-06-10 resulted from reports of unannunciated asymmetric braking during ground operations and landing deceleration. We issued AD 2018-06-10 to detect failure of the power brake valve. The unsafe condition, if not addressed, could result in degraded braking performance and reduced directional control during ground operations and landing deceleration.

Actions Since AD 2018-06-10 was Issued

Since we issued AD 2018-06-10, we were notified by Honda Aircraft Company that Service Bulletin SB-420-32-001, dated January 8, 2018, contains a typographical error in the serial number effectivity, which was also used as the basis for the Applicability section of AD 2018-06- 10. The service bulletin incorrectly listed the applicable Model HA-420 airplane serial number effectivity as 42000011 through 4200089 instead of 42000011 through 42000089. We are issuing this AD to address the unsafe condition on these products by correcting the inadvertent serial number error.

Related Service Information Under 1 CFR Part 51

We reviewed Honda Aircraft Company Service Bulletin SB-420-32-001, Revision B, dated April 16, 2018. The service information 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 productsof 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

[[Page 24017]]

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 we did not provide you with notice and an opportunity to provide your comments before it becomes effective. 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-2018-0463 and product identifier 2018-CE-021-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:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Insert temporary revision into 1 work-hour x $85 Not applicable............ $85 $6,120
the airplane flight manual. per hour = $85. ----------------------------------------------------------------------------------------------------------------

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:

On-Condition Costs ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replace the power brake valve................. 20 work-hours x $85 per hour = $21,878 $23,578
$1,700. ----------------------------------------------------------------------------------------------------------------

Since the addition of airplanes to the Applicability section is based on a typographical error in the manufacturer's service information, all affected airplanes were previously accounted for in the cost estimate of AD 2018-06-10. There is no change to this Cost of Compliance section.

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 theExecutive 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 24018]]

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.
