Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2020-13198

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This proposed AD was prompted by a report which indicated that during takeoff, both the captain's and first officer's airspeed indications froze at 80 knots. This proposed AD would require modifying the air data heat (ADH) system to display the proper airspeed indications, testing, and any applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
