Airworthiness Directives; Ipeco Pilot and Co-Pilot Seats

FAA / Federal Register · 2019-15413

The FAA proposes to supersede airworthiness directive (AD) 2017-22-02, which applies to certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2017-22-02 requires modification and re- identification of the affected seats. Since the FAA issued AD 2017-22- 02, Ipeco has received 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 FAA also determined the need to add additional seat part numbers (P/Ns) to the applicability. This proposed AD would continue to require modification and re-identification of the affected seats. This proposed AD would also require 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. The FAA is proposing this AD to address the unsafe condition on these products.
