Brazil's civil aircraft regulator has issued the second airworthiness directive in a year that focuses on the main landing gear of the Embraer E-190.

The National Agency of Civil Aviation (ANAC) requires E-190 operators to inspect on the side stay and its support assembly within 100 flight cycles. The bushing in the side stay support fitting should be inspected every 100 flight cycles and replaced within 1,200 cycles, the agency said.

ANAC issued the directive after discovering cracks in the side stay caused when the outer bushing migrates slightly out of position.

The side stay problem has been revealed less than one year since the ANAC issued an airworthiness directive on the retraction actuators for the main landing gear.
