Airworthiness Directive · Amendment 39-19230 · Landing gear
Honda Aircraft Company LLC
Superseded. A later AD replaced this one: AD 2018-11-05. Comply with the one in force.
This AD applies to Honda Aircraft Company LLC Model HA-420 airplanes, serial numbers 42000011 through 4200089, 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.
We are adopting a new airworthiness directive (AD) for certain Honda Aircraft Company LLC Model HA-420 airplanes. This AD requires incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves upon condition. This AD was prompted by reports of unannunciated asymmetric braking during ground operations and landing deceleration. We are issuing this AD to address the unsafe condition on these products.
Before further flight after April 13, 2018 (the effective date of this 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.
As of and any time after the effective date of this AD, if the PBV fails any of the pilot checks specified in the temporary revision, 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 in Honda Service Bulletin SB-420-32-001, dated January 8, 2018. Before further flight after installing P/N HJ1-13243-101-009, remove the temporary revision from the Honda HA-420 AFM.
(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 Honda Service Bulletin SB-420-32-001, dated January 8, 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 (i)(1) of this AD, the on-condition replacement required by paragraph (h) of this AD is still required before further flight.
Although Honda Service Bulletin SB-420-32-001, dated January 8, 2018, specifies to submit certain information to the manufacturer, this AD does not require that action.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
