Airworthiness Directive · Amendment 39-22536 · Fuselage main, frame
Vulcanair S.p.A. Airplanes
This AD applies to Vulcanair S.p.A. Model V1.0 airplanes, serial numbers (S/Ns) 1001 through 1034 inclusive, except S/Ns 1008 and 1019, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Vulcanair S.p.A. Model V1.0 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 identifies the unsafe condition as corrosion on the lower fuselage truss. This AD requires a detailed visual inspection of the right-hand (RH) and left-hand (LH) lower rear attachments of the fuselage truss for corrosion, a tactile inspection of the lower rear attachments for missing sealant, and a general visual inspection of the lower fuselage truss welded pipes for corrosion and the related rivets for missing stems and, depending on findings, additional inspections and actions (including a tap test) and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Within 100 hours time-in-service or 12 months after the effective date of this AD, whichever occurs first, do a detailed visual inspection of the right-hand (RH) and left-hand (LH) lower rear attachments of the fuselage truss for corrosion, a tactile inspection of the RH and LH lower rear attachments of the fuselage truss for missing sealant, a general visual inspection of the pipes on the lower fuselage truss for corrosion, and a general visual inspection of the pipes on the lower fuselage truss for rivets with missing stems, in accordance with steps 13 and 14 of Part A, in Part 2, Work Procedure, of Vulcanair S.p.A. Service Bulletin No. VA-22, Revision 0, dated June 15, 2022 (Vulcanair SB VA-22).
(1) If, during the inspections required by the introductory text of paragraph (g) of this AD, no missing sealant and no corrosion of the LH and RH lower rear attachments are detected, and no corrosion and no missing rivet stems of the lower fuselage truss pipes are detected, before further flight, install part number (P/N) 5034-011 plugs on both the RH and LH rear attachments, in accordance with step 16 of Part A, in Part 2, Work Procedure, of Vulcanair SB VA-22. After installation of the plugs, no further action is required by this AD.
(2) If, during the inspections required by the introductory text of paragraph (g) of this AD, corrosion, missing sealant, or missing rivet stems are detected, before further flight, do the following as applicable:
(i) If corrosion or missing sealant is detected during the detailed visual inspection or tactile inspection of the RH and LH lower rear attachments, remove any sealant, and do a detailed visual inspection for corrosion in accordance with step 26 of Part B, in Part 2, Work Procedure, of Vulcanair SB VA-22.
(ii) If corrosion or missing rivet stems are detected during the general visual inspection of the lower fuselage truss pipes, do a detailed visual inspection and tap test for corrosion in accordance with steps 27 and 28 of Part B, in Part 2, Work Procedure, of Vulcanair SB VA-22.
(3) If, during any inspection required by paragraph (g)(2) of this AD, any corrosion is detected on the lower fuselage truss, before further flight, contact the Manager, International Validation Branch, FAA; or European Union Aviation Safety Agency (EASA); or Vulcanair's EASA Design Organization Approval (DOA) for corrective action instructions and do the corrective actions. If approved by the DOA, the approval must include the DOA-authorized signature.
(4) If, during the inspections required by paragraph (g)(2) of this AD, no corrosion is detected, before further flight, apply sealant on rivets with absent stems, restore as necessary the sealant inside the RH and LH lower rear attachments, and install plugs P/N 5034-011 on both the RH and LH rear attachments, in accordance with the instructions in steps 31 and 32 of Part B, in Part 2, Work Procedure, of Vulcanair SB VA-22.
