This AD applies 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, all serial numbers, equipped with L'Hotellier Halon 1211 (BCF) fire extinguishers, having part number (P/N) 863521-01 and having any serial number identified in paragraph 1.A. of L'Hotellier Service Bulletin 863521-26-001, Revision 2, dated February 4, 2010.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Actions (g) Within 90 days after the effective date of this AD, replace all L'Hotellier fire extinguishers having P/N 863521-01 and having any serial number identified in paragraph 1.A. of L'Hotellier Service Bulletin 863521-26-001, Revision 2, dated February 4, 2010, with serviceable fire extinguishers. (h) As of the effective date of this AD, do not install any L'Hotellier fire extinguisher having P/N 863521-01 and having any serial number identified in paragraph 1.A. of L'Hotellier Service Bulletin 863521-26-001, Revision 2, dated February 4, 2010, on any airplane, unless it has been reconditioned with compliant Halon 1211 (BCF) and re-identified, in accordance with the Accomplishment Instructions of L'Hotellier Service Bulletin 863521-26-001, Revision 1, dated January 28, 2010; or Revision 2, dated February 4, 2010. FAA AD Differences Note 1: This AD differs from the MCAI and/or service information as follows: (1) EASA AD 2009-0276R1, dated February 5, 2010, specifies a time of 4 months to do the actions. This AD requires that the actions be done within 90 days. We have determined that a 90-day compliance time will ensure an acceptable level of safety. (2) EASA AD 2009-0276R1, dated February 5, 2010, includes fire extinguishers having certain serial numbers in its applicability. The EASA AD also includes a requirement to inspect to determine if the fire extinguishers have those serial numbers and replacement if necessary. Since the affected fire extinguishers are part of the applicability, it is not necessary to also require inspecting for them. Therefore, this AD includes fire extinguishers having certain serial numbers in its applicability and does not include an additional requirement to inspect for serial numbers; this AD requires replacement of all affected fire extinguishers. Other FAA AD Provisions (i) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. 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. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
