T-34 Center Section Airworthiness Directive

AD2004-25-51 calls out the requirement for an approved inspection program for the fuselage spar carry through structure, and associated flight restrictions.  This inspection program runs out June 2011, and all aircraft over 3,800 total time will require modification of this structure by that time.  We are installing the airframe life extension cable (A.L.E.C), AMOC in this structure to permanently comply with this AD.

A.L.E.C.



The installation of A.L.E.C will provide relief from AD2004-25-51 and allow the T-34 to fly at full flight envelope.  This modification has an unlimited life with a 2,900 hour reinspection interval.
