The FAA is adopting a new airworthiness directive (AD) for certain Polskie Zaklady Lotnicze Sp. z o.o. Model PZL M28 05 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as defective thermo-shrinkable tubes installed on the electrical harnesses located in the fuel tanks. This AD requires a one-time inspection of the electrical harnesses located in the fuel tanks and, depending on findings, replacement of the affected harness. The FAA is issuing this AD to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD:

Service Bulletin No. E/12.141/2018, dated May 15, 2018.
(ii) If there is a tear or any cracking in or any seizing of an electrical wire harness thermo-shrinkable tube, before further flight, replace the harness in accordance with section II. a) Replacement of harness KL8 (KP), II. b) Replacement of Harness KL9 (KP9), or II. c) Replacement of harness KL10 (KP10), as applicable, of the Procedure for Bulletin Execution in Polskie Zaklady Lotnicze Sp. z o.o.
