Airworthiness Directive · Amendment 39-14052 · Aviointeriors S.p.A. Series 312 Seats
Aviointeriors S.p.A. Series 312 Seats
This AD applies to Aviointeriors S.p.A. (formerly ALVEN), model 312 seats. These seats are installed in, but not limited to, Fokker Model F27 Mark 050, Mark 500, and Mark 600 airplanes.
The FAA is superseding an existing airworthiness directive (AD), that is applicable to Aviointeriors S.p.A. (formerly ALVEN), series 312 seats. That AD requires initial and repetitive inspections of the seat central crossmember for cracks, and if necessary, replacing the crossmember with a new crossmember. This ad requires the same actions and adds other crossmember part numbers for inspection. In addition, this AD replaces the original design crossmembers with reinforced design crossmembers as optional terminating actions to the repetitive inspections. This AD results from reports of 88 cracked seat central crossmembers and 60 aisle side crossmembers, to date; and, from the introduction of reinforced optional seat crossmembers by the manufacturer. We are issuing this AD to prevent the loss of the structural integrity of the seat due to cracks in seat crossmembers, which could lead to passenger injury.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Perform an initial visual inspection of the crossmember for cracks, within 12,000 hours time-in-service (TIS); or within 180 days after the effective date of this AD if the crossmember has more than 12,000 hours TIS, as follows:
(1) Inspect seat central crossmembers, part number (P/N) DM03437-1, using Section 2. of Inspection Procedure of Aviointeriors Service Bulletin (SB) No. 312/912-01, Revision 2, dated August 1, 2000.
(2) Replace any cracked central crossmember with a new crossmember of the same P/N. Use Section 3. Crossmember Replacement Procedure, Steps 3.1 though 3.10 of Aviointeriors SB No. 312/912-01, Revision 2, dated August 1, 2000.
(3) Inspect seat aisle side crossmembers, P/Ns DM03435-1, DM03435-2, and DM03437-1 (Disabled People seat application), using Section 2. of Inspection Procedure of Aviointeriors SB No. 312/912-02, Revision 1, dated August 1, 2000.
(4) Replace any cracked aisle side crossmember with a new crossmember of the same P/N. Use Section 3. Crossmember Replacement Procedure, Steps 3.1 though 3.8 of Aviointeriors SB No. 312/912-02, Revision 1, dated August 1, 2000.
Perform repetitive visual inspections of crossmembers, P/N DM03435-1, DM03435-2, and DM03437-1, for cracks, within 650 hours TIS after the last inspection. Use paragraphs (f)(1) through (f)(4) of this AD to inspect and disposition crossmembers.
As optional terminating actions to the repetitive inspections required by this AD, do the following:
(1) Replace seat central crossmembers, P/N DM03437-1, with reinforced crossmembers, P/N F11541300000. Use Section 2. Crossmember Replacement Procedure, Steps 2.1 through 2.11 of Aviointeriors SB No. 312/912-03, dated August 1, 2000.
(2) Replace seat aisle side crossmembers, P/N DM03435-1, DM03435-2, and DM03437-1 (Disabled People seat application), with reinforced crossmembers, P/N F11555400000, F11555500000, and F11541300000, respectively. Use Section 2. Crossmember Replacement Procedure, Steps 2.1 through 2.11 of Aviointeriors SB No. 312/912-04, dated August 1, 2000.
