Airworthiness Directive 2019-24-18
one-timeAirworthiness Directives; the Boeing Company Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes, Model 757 airplanes, and Model 767-200, -300, -300F, and -400ER series airplanes. This AD was prompted by reports of nuisance stick shaker activation while the airplane accelerated to cruise speed at the top of climb. This AD was also prompted by an investigation of those reports that revealed that the angle of attack (AOA) (also known as angle of airflow) sensor vanes could not prevent the build-up of ice, causing the AOA sensor vanes to become immobilized, which resulted in nuisance stick shaker activation. This AD requires a general visual inspection of the AOA sensors for certain AOA sensors, and replacement of affected AOA sensors. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2019-24-18 applies to
727 series per Boeing Alert Service Bulletin 727-34A0247, Revision 1, dated October 1, 2019, excluding airplanes with variable numbers QB065, QD191, QD192, QD402, QD403, QD407, and QD410; 757 series per Boeing Alert Service Bulletin 757-34A0611, Revision 1, dated March 22, 2019; 767 series per Boeing Alert Service Bulletin 767-34A0828, dated December 6, 2018.
Whether AD 2019-24-18 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
