This AD applies to Sicma Aero Seat 90xx and 92xx series passenger seats with part numbers (P/Ns) listed in Annex 1, dated July 17, 2002, of Sicma Aero Seat Service Bulletin 92-25-005, Issue 3, dated January 17, 2003. These products are installed on, but not limited to, ATR—GIE Avions de Transport Régional Model ATR42-200, -300, -320, and -500 airplanes, and Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes; certificated in any category. Note 1: This AD applies to certain Sicma Aero Seat passenger seats 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) 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.

Unless already done, do the following actions. (1) Within 500 flight hours after the effective date of this AD, perform a visual inspection of central spreaders, P/N 92-000100-200-1 and P/N 92-000101-200-1, of the affected seats using the Accomplishment Instructions, “Part One: Checking Procedure,” of Sicma Aero Seat Service Bulletin 92-25-005, Issue 3, dated January 17, 2003 (“the service bulletin”). If no crack is found, repeat this inspection at intervals not exceeding 500 flight hours until a new central spreader, P/N 92-000100-200-1 or P/N 92-000101-200-1, and doublers, P/N 00-6536, are installed in accordance with “Part Three: Central Spreader Replacement” of the service bulletin. Type 1, 2, and 3 cracks are defined in the Accomplishment Instructions, “Part One: Checking Procedure,” of the service bulletin. (i) If a type 1 crack is found, within 6 months or 500 flight hours after accomplishing the inspection, whichever comes first, check the crack to determine that it did not enlarge to a type 2 or type 3 crack by using the Accomplishment Instructions, “Part One: Checking Procedure,” of the service bulletin; install doublers, P/N 00-6536, by using the Accomplishment Instructions, “Part Two: Central Spreader Modification,” of the service bulletin, and record this modification by using “B—Seat identification” of the Accomplishment Instructions, “Part One: Checking Procedure,” of the service bulletin. (ii) If a type 2 or 3 crack is found, before further flight, replace the affected central spreader with a new one with the same part number, equipped with doublers, P/N 00-6536, by using the Accomplishment Instructions, “Part Three: Central Spreader Replacement,” of the service bulletin. (iii) If a new spreader is unavailable, before further flight, do a temporary repair by installing doublers, P/N 00-6536, by using the Accomplishment Instructions, “Part Two: Central Spreader Modification,” of the service bulletin. This temporary repair may remain in place no longer than 500 flight hours or six months, whichever comes first. After removing the temporary repair, before further flight, install a new spreader with the same P/N equipped with doublers, P/N 00-6536, by using the Accomplishment Instructions, “Part Three: Central Spreader Replacement,” of the service bulletin, and record this modification by following the instructions in “B—Seat identification” of the Accomplishment Instructions, “Part Three: Central Spreader Replacement,” of the service bulletin. (2) If not already done, within 24 months after the effective date of this AD, install doublers, P/N 00-6536, on new central spreaders of affected seats by using the Accomplishment Instructions, “Part Three: Central Spreader Replacement,” of Sicma Aero Seat Service Bulletin 92-25-005, Issue 3, dated January 17, 2003 (“the service bulletin”). Record this modification by following instructions in “B—Seat identification” of the Accomplishment Instructions, “Part Three: Central Spreader Replacement,” of the service bulletin. Installing a new central spreader P/N 92-000100-200-1 or 92-000101-200-1, and doublers, P/N 00-6536 on all affected seats terminates the requirements of this AD. (3) Actions accomplished before the effective date of this AD in accordance with Sicma Aero Seat Service Bulletin 92-25-005, Issue 1, dated August 29, 2002; and Issue 2, dated October 29, 2002; are considered acceptable for compliance with the corresponding actions specified in this AD.

The AMOC approval letter must specifically reference this AD.

Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
