Airworthiness Directive · Amendment 39-19608 · Wings
Vulcanair S.p.A. Airplanes
This AD applies to Vulcanair S.p.A. Model AP68TP-300 “SPARTACUS” airplanes, serial numbers (S/N) 8001 through 8006, 8008, 8009, and 8011; and Model AP68TP-600 “VIATOR” airplanes, S/N 9001 through 9005, and 9010; certificated in any category.
We are adopting a new airworthiness directive (AD) for Vulcanair S.p.A. Model AP68TP-300 "SPARTACUS" and Model AP68TP-600 "VIATOR" airplanes. This AD results from 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 cracks on wing ribs, which could result in reduced structural integrity of the wing assembly. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) through (3) within 3 months after April 29, 2019 (the effective date of this AD) or within 50 hours time-in-service after April 29, 2019 (the effective date of this AD), whichever occurs first.
(1) Inspect the left hand (LH) and right hand (RH) sides of wing rib number 3 and wing rib number 4 for missing reinforcements, cracks, and corrosion by following the Work Procedure, paragraphs 1 through 6, of Vulcanair Aircraft Service Bulletin No. TP-43, First Issue, dated October 15, 2018.
(2) If there is no corrosion and no cracks and if a reinforcement is missing, before further flight, install the reinforcement in accordance with the Work Procedure, paragraphs 1 through 19, of Vulcanair Aircraft Service Instruction No. 106, First Issue, dated October 15, 2018, for wing rib number 3 or the Work Procedure, sections 2.2 and 2.3, of Vulcanair Aircraft Service Instruction No. 107, First Issue, dated October 15, 2018, for wing rib number 4, as applicable to the missing reinforcement.
(3) If there is any corrosion or a crack, before further flight, repair the wing spar in accordance with a method approved by the Manager, Small Airplane Standards Branch, FAA, at the address specified in paragraph (g) of this AD. For a repair method to be approved by the Manager, Small Airplane Standards Branch, as required by this paragraph, the Manager's approval letter must specifically refer to this AD.
