We are adopting a new airworthiness directive (AD) for certain Zodiac Seats California LLC seating systems. This AD was prompted by a determination that the affected seating systems may cause serious injury to the occupant during forward impacts when subjected to certain inertia forces. This AD requires removing affected seating systems. We are issuing this AD to address the unsafe condition on these products.
Within 60 months after the effective date of this AD, remove all seating systems having a model number and part number identified in table 1 to paragraphs (c), (g), (i), (j), and (k) of this AD.
For the purposes of this AD, a “direct” spare has the same part number as the part it replaces.
As of the effective date of this AD, no person may install on any airplane any Zodiac Seats California LLC seating systems having any model number and part number identified in table 1 to paragraphs (c), (g), (i), (j), and (k) of this AD that are approved under technical standard order (TSO) TSO-C127a; except as specified in paragraphs (i)(1) and (i)(2) of this AD.
(1) Seating systems may be removed from service for the purpose of performing maintenance activities and reinstalled on airplanes operated by the same operator, but only until the operator complies with the removal of affected seating systems required by paragraph (g) of this AD.
(2) New seating systems may be installed as direct spares for the same part number seating systems, but only until the operator complies with the removal of affected seating systems required by paragraph (g) of this AD. Seating systems installed as direct spares are subject to the applicable requirements and compliance times specified in this AD.
Installation of a seating system having any model number and part number identified in table 1 to paragraphs (c), (g), (i), (j), and (k) of this AD, other than those installed as direct spares, is considered a new installation that needs approval; except that re-arrangement of the existing installed seating systems on an airplane is acceptable until the operator complies with the removal of affected seating systems required by paragraph (g) of this AD, provided the re-arrangement follows the same installation instructions and limitations as the original certification (e.g., if the original limitations allowed 32-inch to 34-inch pitch, the new layout must be pitched within that range).
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
