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 the products listed above. 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 times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, do a general visual inspection for cracking of the backrest links, P/Ns 90-000200-104-1 and 90-000200-104-2, in accordance with Part One, “Checking Procedure,” of Sicma Aero Seat Service Bulletin 90-25-012, Issue 5, 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 90-25-012, Issue 5, 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 backrest links having the same part number (P/N 90-000200-104-1 or 90-000200-104-2), in accordance with Part Two, “Replacement Procedure,” of Sicma Aero Seat Service Bulletin 90-25-012, Issue 5, 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 90-25-012, Issue 5, dated March 19, 2004): Before further flight, replace both backrest links of the affected seat with new backrest links having the same part numbers (P/N 90-000200-104-1 or 90-000200-104-2), in accordance with Part Two, “Replacement Procedure,” of Sicma Aero Seat Service Bulletin 90-25-012, Issue 5, dated March 19, 2004.
(4) If no cracking is found during the inspection required by paragraph (f)(1) of this AD: At the later of the times specified in paragraphs (f)(4)(i) and (f)(4)(ii) of this AD, replace the links, P/Ns 90-000200-104-1 and 90-000200-104-2, with new backrest links having the same part numbers (P/N 90-000200-104-1 or 90-000200-104-2), in accordance with Part Two, “Replacement Procedure,” of Sicma Aero Seat Service Bulletin 90-25-012, Issue 5, dated March 19, 2004.
(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.
(5) Actions done before the effective date of this AD in accordance with Sicma Aero Seat Service Bulletin 90-25-012, Issue 3, dated October 3, 2001; and Sicma Aero Seat Service Bulletin 90-25-012, Issue 4, dated December 19, 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 required time for replacing those links. This AD requires replacement of the link before 12,000 flight hours since new, or within 900 flight hours or 5 months after 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.
