Claim:
A covering ( 22 ) of a fuselage ( 1 ) for aircraft comprising propeller engines ( 3 ), said covering ( 22 ) comprising: an opening ( 12 ) which is surrounded by a structural frame formed by ribs ( 5 ) and stringers ( 6 ) of the aircraft around an area of maximum acoustic impact of the propeller engines ( 3 ), said opening ( 12 ) further comprising a non-structural panel ( 7 ), wherein a peripheral flange of the non-structural panel is joined to the structural frame by means of a non-rigid joint which attenuates vibrations through said joint, thus reducing indirect acoustic noise and indirect structural noise generated by the propeller engines ( 3 ) inside a passenger cabin of the aircraft, wherein the covering ( 22 ) surrounds the fuselage ( 1 ) around the entire perimeter of the fuselage ( 1 ), and wherein the non-structural panel ( 7 ) comprises a non-metal sandwich-type core ( 31 ) in turn comprising an upper skin ( 32 ) and a lower skin ( 33 ).
