Airworthiness Directive · Amendment 39-19338 · Time limits
Honda Aircraft Company LLC Airplanes
This AD applies to Honda Aircraft Company LLC Model HA-420 airplanes with a serial number in the range of 42000011 through 42000112, 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 new and revised airworthiness limitations into the airplane's maintenance program. This AD was prompted by a report that several maintenance tasks were omitted from the airworthiness limitations section of the Honda Aircraft Company, Inc. Model HA-420 Airworthiness Limitation and Inspection Manual (ALIM). We are issuing this AD to address the unsafe condition on these products.
Comply with the action of this AD within 30 days after August 13, 2018 (the effective date of this AD) or within 15 hours time-in-service (TIS) after August 13, 2018 (the effective date of this AD), whichever occurs first, unless already done. The airworthiness limitations section revision required in paragraph (g) of this AD contains new and reduced inspection intervals. Once you comply with paragraph (g) of this AD, if the hours TIS of your airplane exceed the threshold of any new limitation, you are required to comply with the replacement times or inspection intervals before further flight. This includes, but is not limited to, the following revised inspections:
(1) The 600-hour TIS interval 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.
(2) The 600-hour TIS interval 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.
Revise 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 Airworthiness Limitations section 05-60-00, “Airworthiness Limitation—Inspection/Check,” dated May 1, 2018. Incorporating these airworthiness limitations makes them mandatory (reference 14 CFR 43.16 and 14 CFR 91.403(c)).
Note 1 to paragraph (g) of this AD: Airworthiness Limitations section 05-60-00 is contained in the Honda Aircraft Company, Inc. Model HA-420 ALIM.
After revising the airworthiness limitations section as required by paragraph (g) of this AD, no alternative replacement times or inspection intervals may be approved unless the actions and/or intervals are approved as an alternative method of compliance in accordance with the procedures specified in paragraph (k)(1) of this AD.
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.
