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 Honda corrected these procedures and superseded the current procedures (−801) with the new procedures (−802).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 Start Printed Page 38658systems, 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 Start Printed Page 38659the 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.
