Airworthiness Directive · Amendment 39-19471 · Landing gear
Honda Aircraft Company LLC
This AD applies to Honda Aircraft Company LLC (Honda) Model HA-420 airplanes, all serial numbers, that:
(1) Have power brake valve (PBV), part number (P/N) HJ1-13243-101-005 or HJ1-13243-101-007, installed; and
(2) are certificated in any category.
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.
Before further flight after May 29, 2018 (the effective date retained from AD 2018-11-05) insert Honda Temporary Revision TR 01.1, dated February 16, 2018 (temporary revision), into the Honda HA-420 Airplane Flight Manual (AFM). The procedures listed in the temporary revision are required while operating with PBV P/N HJ1-13243-101-005 or P/N HJ1-13243-101-007 installed. 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) through (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.
As of and at any time after May 29, 2018 (the effective date retained from AD 2018-11-05), 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 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. The replacement must be done using the Accomplishment Instructions in either Honda Service Bulletin SB-420-32-001, dated January 8, 2018 (SB-420-32-001), or Honda Service Bulletin SB-420-32-001, Revision B, dated April 16, 2018 (SB-420-32-001, Revision B). Before further flight after installing P/N HJ1-13243-101-009, remove the temporary revision from the Honda HA-420 AFM.
Although 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.
Within the next 12 months after November 27, 2018 (the effective date of this AD), if not previously done as a result of paragraph (h) of this AD, replace 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. The replacement must be done using the Accomplishment Instructions in either SB-420-32-001 or SB-420-32-001, Revision B. Before further flight after installing P/N HJ1-13243-101-009, remove the temporary revision from the Honda HA-420 AFM.
