Airworthiness Directive · Amendment 39-13224 · McDonnell Douglas Model 717-200 Airplanes
McDonnell Douglas Model 717-200 Airplanes
All Model 717-200 airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all McDonnell Douglas Model 717 airplanes. This action requires repetitive inspections for cracking of the support fitting assemblies and stop pads of the main spoiler actuators, and follow-on actions. This action is necessary to find and correct cracking of the support fitting assemblies of the main spoiler actuators, which could result in damage of adjacent structure such as the rear spar or upper skin panel, and consequent reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
