Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) Airplanes

摘要

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, that requires an inspection of the thrust reverser cascades for correct installation; removing and reinstalling the cascade in the correct location, if necessary; and reworking the thrust reverser cascades to add locating spigots (metal protrusions) to each cascade; as applicable. This action is necessary to prevent asymmetric reverse thrust and consequent loss of control of the airplane during reverse thrust operation. This action is intended to address the identified unsafe condition.
