(c) Applicability This AD applies to: (1) Diamond Aircraft Industries GmbH (DAI) Model DA 42 NG airplanes, serial numbers (S/N) 42.N303 through 42.N314, 42.N319, and 42.N320, certificated in any category, with a fuel tank connection hose part number (P/N) D4D-2817-10-70 installed; and (2) DAI Models DA 42, DA 42 NG, and DA 42 M-NG airplanes, all serial numbers, certificated in any category, with a fuel tank connection hose P/N D4D-2817-10-70 identified in the Technical Details, section I.11, of Diamond Aircraft Mandatory Service Bulletin MSB 42-138/MSB 42NG-080, dated July 1, 2019 (issued as one document) (Diamond MSB 42-138/42NG-080), installed. (d) Subject Joint Aircraft System Component (JASC) Code 2810, Fuel Storage. (e) Unsafe Condition This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as dissolved or detached fuel tank hose material entering the main fuel tank chambers. The FAA is issuing this AD to prevent restricted fuel flow, which could result in fuel starvation. The unsafe condition, if not addressed, could result in fuel starvation and reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Within 100 hours time-in-service (TIS) after the effective date of this AD or within 4 months after the effective date of this AD, whichever occurs first, replace the main fuel tank connection hoses in accordance with the Instructions, sections III.1 and III.2, in DAI Work Instruction WI-MSB 42-138/WI-MSB 42NG-080, Revision 0, dated July 1, 2019, (issued as one document) attached to Diamond MSB 42-138/42NG-080. Instead of P/N D4D-2817-10-70_01, you may also replace a fuel tank connection hose with P/N D4D-2817-10-70 that is not identified in paragraph (c) of this AD. (2) As of the effective date of this AD, do not install a fuel tank connection hose P/N D4D-2817-10-70 identified in paragraph (c) of this AD on any airplane.
