AD 2004-09-18 69 FR 24950 Active

This amendment adopts a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes, that requires repetitively inspecting the seat rails located in the passenger cabin for evidence of damage and corrosion, repairing any damage or corrosion, and replacing any floor panels found to be "soft" due to ingress of moisture. This action is necessary to detect and correct corrosion on the seat rails for the passenger seats, which could result in the reduced structural integrity of the passenger seats, detachment of the seats from the seat rails, and injury to passengers. This action is intended to address the identified unsafe condition.
