Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This proposed AD would require doing a general visual inspection of the passenger seat track attachments to determine if the attachment rod is installed and to check the torque value of the attachment bolts, and doing any corrective actions if necessary. This proposed AD results from the finding of missing rods, which attach the passenger seat tracks to the airplane structure to absorb loads. We are proposing this AD to detect and correct missing attachment rods, which could result in reducing the ability of the seat to withstand a hard landing or rejected takeoff and possible injury to passengers.
