AD 2018-21-13

We are superseding Airworthiness Directive (AD) 2018-11-05 for certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. AD 2018-11-05 required incorporating a temporary revision into the airplane flight manual (AFM) and replacing the faulty power brake valve (PBV) upon condition. We issued AD 2018-11-05 as a short-term action to address the immediate need to detect and replace a faulty PBV. This AD retains the actions required in AD 2018-11-05 and requires replacing the faulty PBV with the improved part. We are issuing this AD to address the long-term corrective action and address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to remove AD 2018-11-05, Amendment 39-19293 (83 FR 24016, May 24, 2018) (``AD 2018-11-05''), and add a new AD to correct an unsafe condition on certain Honda Model HA-420 airplanes. We issued AD 2018- 11-05 as a short-term immediate action to detect a faulty PBV. AD 2018- 11-05 required inserting a temporary revision into the AFM and replacing the installed PBV, part number (P/N) HJ1-13243-101-005 or P/N HJ1-13243-101-007, with an improved PBV, P/N HJ1-13243-101-009, if any of the procedures listed in the AFM temporary revision revealed a leaking PBV. In addition, AD 2018-11-05 allowed replacing the installed P/N HJ1-13243-101-005 or P/N HJ1-13243-101-007 with the improved P/N HJ1-13243-101-009 as an optional terminating action for the temporary revision procedures in the AFM. AD 2018-11-05 resulted from reports of unannunciated asymmetric braking during ground operations and landing deceleration.
The NPRM published in the Federal Register on June 7, 2018 (83 FR 26381). The NPRM was issued as follow-on rulemaking to propose the long-term actions necessary to address the faulty PBV. The NPRM proposed to retain the requirements of AD 2018-11-05 and require replacing the installed PBV, P/N HJ1-13243-101-005 or P/N HJ1-13243- 101-007, with the improved PBV, P/N HJ1-13243-101-009, within 12 months. We are issuing this AD to address the long-term corrective action.

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 this AD as proposed except for minor editorial changes. We also removed the optional terminating action provision, which allowed operators to replace the PBV at any time to terminate the pre-flight checks in the AFM, because that provision was unnecessary. The requirement to replace the PBV within 12 months of the effective date of this AD provides operators with that same option. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing 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 Honda AFM Temporary Revision TR 01.1, dated February 16, 2018 (temporary revision), Honda Service Bulletin SB-420-32-001, dated January 8, 2018 (SB-420-32-001), and Honda Service Bulletin SB- 420-32-001, Revision B, dated April 16, 2018 (SB-420-32-001, Revision B). The temporary revision contains procedures for pilot checks of the braking system before every flight during ground operations and before every landing, procedures for landing with a leaking PBV, and procedures for rechecking the PBV for leaking after landing. The temporary revision also includes instructions for corrective actions if any indication of a leaking PBV is found after landing. SB-420-32-001 and SB-420-32-001, Revision B both contain procedures for replacing a faulty PBV with an improved 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.

Differences Between This Proposed AD and the Service Information

SB-420-32-001 and SB-420-32-001, Revision B specify submitting certain information to the manufacturer. This AD does not require that action.

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 AFM. per hour = $85. Replace the power brake valve 20 work-hours x $21,878.................... 23,578 1,697,616
(PBV). $85 per hour =
$1,700. ----------------------------------------------------------------------------------------------------------------

We provided the cost of replacing the PBV as an on-condition cost based on the procedures in the temporary revision and as an optional terminating action in AD 2018-11-05. We have no way of determining how many owner/operators of the affected airplanes may have already done this replacement. Therefore, we have included a total cost for all affected airplanes.
The difference in the Cost of Compliance between AD 2018-11-05

[[Page 53370]]

and this AD is the requirement to replace the power brake valve.

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 likelyto 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 have 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 reasonsdiscussed 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.
