Note 1: This AD applies to Sicma Aero Seat passenger seat assemblies as installed on any airplane, regardless of whether the airplane has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance according to paragraph (g)(1) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
We are adopting a new airworthiness directive (AD) for Sicma Aero Seat 88xx, 89xx, 90xx, 91xx, 92xx, 93xx, 95xx, and 96xx series passenger seat assemblies, installed on various transport category airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) At the later of the compliance times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, do a general visual inspection of the backrest links having P/Ns 90-000200-104-1 and 90-000200-104-2, in accordance with Part One of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004:
(i) Before 6,000 flight hours on the backrest link since new.
(ii) Within 900 flight hours or 5 months after the effective date of this AD, whichever occurs later.
(2) If, during the inspection required by paragraph (f)(1) of this AD, cracking is found between the side of the backrest link and the lock-out pin hole but the cracking does not pass this lock-out pin hole (refer to Figure 2 of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004): Within 600 flight hours or 3 months after doing the inspection, whichever occurs first, replace both backrest links of the affected seat with new, improved backrest links having P/Ns 90-100200-104-1 and 90-100200-104-2, in accordance with Part Two of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004.
(3) If, during the inspection required by paragraph (f)(1) of this AD, cracking is found that passes beyond the lock-out pin hole (refer to Figure 2 of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004): Before further flight, replace both backrest links of the affected seat with new, improved backrest links having P/Ns 90-100200-104-1 and 90-100200-104-2, in accordance with Part Two of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004.
(4) If no cracking is found during the inspection required by paragraph (f)(1) of this AD: Do the replacement required by paragraph (f)(5) of this AD at the compliance time specified in paragraph (f)(5) of this AD.
(5) At the later of the compliance times specified in paragraphs (f)(5)(i) and (f)(5)(ii) of this AD, replace the links, P/Ns 90-000200-104-1 and 90-000200-104-2, with new improved links, P/Ns 90-100200-104-1 and 90-100200-104-2, in accordance with Part Two of Sicma Aero Seat Service Bulletin 90-25-013, Issue 4, dated March 19, 2004, including Annex 1, Issue 2, dated March 19, 2004. Doing this replacement for an affected passenger seat assembly terminates the inspection requirements of paragraph (f)(1) of this AD for that passenger seat assembly.
(i) Before 12,000 flight hours on the backrest links, P/Ns 90-000200-104-1 and 90-000200-104-2, since new.
(ii) Within 900 flight hours or 5 months after the effective date of this AD, whichever occurs later.
(6) Actions done before the effective date of this AD in accordance with Sicma Aero Seat Service Bulletin 90-25-013, Issue 3, dated December 19, 2001, including Annex 1, Issue 1, dated June 26, 2001, are acceptable for compliance with the corresponding actions of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: The MCAI specifies doing repetitive inspections for cracking of links having over 12,000 flight hours since new until the replacement of the link is done. This AD does not include those repetitive inspections because we have reduced the compliance time for replacing those links. This AD requires replacing the link before 12,000 flight hours since new or within 900 flight hours or 5 months of the effective date of this AD, whichever occurs later.
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.
