These passenger seat assemblies are installed on, but not limited to, the airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category.

We are superseding Airworthiness Directive (AD) 2014-20-11, for Zodiac Seats France 9140, 9166, 9173, 9174, 9184, 9188, 9196, 91B7, 91B8, 91C0, 91C2, 91C4, 91C5, 91C9, 9301, and 9501 series passenger seat assemblies. AD 2014-20-11 required a general visual inspection for cracking of backrest links; replacement with new links if cracking is found; and eventual replacement of all links with new links. This AD was prompted by a determination that a model designation specified in paragraph (c)(1) of that AD was incorrect. This new AD identifies the correct model designation. We are issuing this AD to detect and correct cracks in the backrest links, which could affect the structural integrity of seat backrests. Failure of the backrest links could result in injury to an occupant during emergency landing conditions.
