AD 2006-03-17 71 FR 6973

The FAA is adopting a new airworthiness directive (AD) for certain Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01 airplanes. This AD requires you to repetitively inspect fuselage frame No. XI for cracks and to replace fuselage frame No. XI and install reinforcement modifications if any cracks are found. The installation of reinforcement modifications is terminating action for the repetitive inspection requirement. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the European Union. We are issuing this AD to detect and correct cracks in fuselage frame No. XI, which could result in failure of this frame. This failure could lead to failure of the tail section of the airplane.
