### ATA 25 Equipment & Furnishings – Passenger Seat Backrest - Replacement

Manufacturer(s): Aviointeriors S.p.A.

Applicability: Passenger Seats 12M( )( )-( )( )( )( )( )( ), all part numbers (P/N) equipped with backrest P/N 313033000000 or 313033100000, as listed in Section 1.A of Aviointeriors Service Bulletin (SB) 12M/F68-06. The affected seats are known to be installed on, but not limited to, the following aircraft:
- ATR 42 series;
- ATR 72 series.
Reason: Failures of the recline actuator metal fitting have been reported on seat backrests of in-service aircraft. EASA AD 2006-0350, which is superseded by this AD, was issued to initially mandate a one-time inspection of the applicable backrests, replace all fittings that have tool marks and re-identify the backrest seat P/N. Si nce the issuance of the AD, cycle testing performed by Aviointeriors identified a life limitat ion also for backrests that do not have tool marks. Consequently the present AD mandates the replacement of those backrests before reaching the threshold specified in the compliance paragraph of this AD. Actions required by this AD are intended to prevent further failures of the seat backrests which could result in injury to passengers or crew members during an emergency landing.EASA AD No.: 2008-0135

EASA Form 110 Page 2/2 Effective Date: 30 July 2008

Required action(s) and Compliance Time(s): Required as indicated, unless already accomplished:

 Before the accumulation of 13 000 total flight cycles (FC) since the seat first installation on aircraft but no later than 31 January 2009, whichever occurs first, replace the backrest P/N 313033000000 and/or 313033100000 in accordance with the instructions given in Aviointeriors Service Bulletin (SB) 12M/F68-06.
In case at the effective date of this AD seats have already exceeded the FC threshold mentioned above, it is allowed to perform the backrest replacement within 500 FC a fter the effective date of this AD, but no later 31 January 2009, whichever occurs first.

 After the effective date of this AD, no person shall install Aviointeriors passenger seat assembly P/N 12M( )( )-( )( )( )( )( )( ) with backrests having P/N 313033000000 or 313033100000 (being either unmarked or marked with “O“ as per Aviointeriors SB 12M/F68-01 Revision 1) on any aircraft.

 In case there is no possibility to replace the seat backrests within the required compliance time, the aircraft may be dispatched with the affected seat installed provided:

• Affected seat does not block any emergency exit; and
