(a) Effective Date This AD is effective September 12, 2018. (b) Affected ADs None. (c) Applicability This AD applies to GE Aviation Czech H80-200 turboprop engines with propeller governor part number, (P/N) P-W22-1, and Avia Propeller AV-725 propellers installed. These engines are installed on Aircraft Industries (AI) L410 UVP-E20 and L 410 UVP-E20 CARGO airplanes. (d) Subject Joint Aircraft System Component (JASC) Code 7600, Engine Controls. (e) Unsafe Condition This AD was prompted by an accident on an AI L 410 UVP-E20 airplane caused by one propeller going to a negative thrust position during the landing approach. We are issuing [[Page 43744]] this AD to require engine modification to prevent asymmetric thrust. The unsafe condition, if not addressed, could result in failure of the beta switch, loss of engine thrust control, and reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Within 25 flight hours, 20 flight cycles, or 30 days, whichever occurs first after the effective date of this AD, inspect and adjust the engine push-pull control, P/N M601-76.3, and replace beta switch, P/N P-S-2, with beta switch, P/N P-S-2A, in accordance with paragraphs 1.6. and 1.7. of GE Aviation Czech Service Bulletin (SB) SB-H80-76-00-00-0036, Revision No. 02, dated March 29, 2018. (h) Installation Prohibition After the effective date of this AD: (1) Do not install beta switch, P/N P-S-2, on any engine. (2) Do not install a GE Aviation Czech H80-200 turboprop engine on any airplane unless the required actions in paragraph (g) of this AD have been complied with.
