### ATA 25 Equipment & Furnishings – Passenger Seats – Inspection / Repair / Modification

Manufacturer(s): Sicma Aero Seat

Applicability: Passenger Seats models 9401, 9402, 9404, 9405, 9406, 9407, 9408 and 9409, all Part Numbers (P/N), except fr ont row and aft facing seat and those modified to ‘Amendment B’ standard. The affected seats are known to be installed on, but not limited to, ATR 42 and ATR 72 series aircraft.
Reason: Several occurrences of cracked central and lateral spreaders on passenger seats models 9401 and 9402 have been reported to Sicma Aero Seat. This condition, if not corrected, can le ad to further cracking of the seat spreaders, causing injury to passe ngers or crew members during heavy turbulence in flight or in the event of an emergency landing. For the reasons stated above, this Airworthiness Directive (AD) requires repetitive inspections of the affect ed seats and, depending on findings, the repair or replacement of damaged spreaders with an improved design (‘Amendment B’ standard). The repl acement of all spreaders (i.e. modification to ‘Amendment B’ standard) terminates the repetitive inspection requirements. This AD, superseding EASA AD 2008- 0080, retains the original requirements, but adds a seat model (9 409) that was inadvertently missing in the original AD and excludes front row and aft facing seats from the applicability.EASA AD No.: 2008-0097
