Airworthiness Directives; Vulcanair S.p.A. Models P 68 “OBSERVER”, P68 “OBSERVER 2”, and P68TC “OBSERVER” Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Vulcanair S.p.A. (Vulcanair) Models P 68 "OBSERVER", P68 "OBSERVER 2", and P68TC "OBSERVER" airplanes. This AD requires you to inspect the nose landing gear (NLG) upper strut for evidence of cracking (cracks or crack beginnings), and replace the NLG upper strut if you find evidence of cracking. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent failure of the NLG upper strut caused by cracking in the area of the seeger retaining ring groove, which could result in loss of control of the airplane.
