AD FAA-2016-6427

We are superseding Airworthiness Directive (AD) 2007-11-13 for all The Boeing Company Model 717-200 airplanes. AD 2007-11-13 required revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new removal limits for certain components of the flap system and to reduce the inspection intervals for fatigue cracking of principal structural elements (PSE). This new AD requires revising the maintenance or inspection program, as applicable, to incorporate reduced intervals for the inspections for three PSEs and add nondestructive inspections (NDIs). This AD was prompted by a new Airworthiness Limitations Instruction (ALI) revision that incorporates NDI techniques and reduced repetitive inspection intervals for three PSEs. We are issuing this AD to address the unsafe condition on these products.
