## Abstract

The FAA is superseding Airworthiness Directive (AD) 2017-22-02 for certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2017-22-02 required modification and re-identification of the affected seats. This AD continues to require modification and re-identification of the affected seats. This AD also requires initial and repetitive inspections of the affected tracklock springs and, depending on the findings, replacement of the tracklock springs with a part eligible for installation. This AD was prompted by reports that the tracklock spring modification required by AD 2017-22-02 does not adequately address the issue of unexpected seat movement during takeoff and landing and the need to add additional seat part numbers (P/Ns) to the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
