Airworthiness Directive · Amendment 39-21399 · Ice and rain protection
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 717-200 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This AD was prompted by a report that during takeoff, both the captain's and first officer's airspeed indications froze at 80 knots. This AD requires modifying the air data heat (ADH) system to display the proper airspeed indications, testing, and any applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 717-30A0009, dated March 31, 2020, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 717-30A0009, dated March 31, 2020.
Where Boeing Alert Service Bulletin 717-30A0009, dated March 31, 2020, uses the phrase “the original issue date of this service bulletin,” this AD requires using “the effective date of this AD.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
