AD 2019-06-10 84 FR 13999

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.
