Airworthiness Directive · Amendment 39-16210 · Fire protection
ATR-GIE Avions de Transport Régional Model ATR42 and ATR72 Airplanes
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.
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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
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.
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.
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.
