Airworthiness Directive · Amendment 39-15385 · Fuel
ATR Model ATR42 and ATR72 Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD.
(1) ATR Model ATR42-200, -300, -320, and -500 airplanes, certificated in any category, serial numbers 1 through 642.
(2) ATR Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes, certificated in any category, serial numbers 1 through 724.
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:
Within 41 months after the effective date of this AD, unless already done, modify the fuel system and do all applicable related investigative and corrective actions according to the instructions given by the applicable service bulletin listed in Table 1 of this AD. Do all applicable related investigative and corrective actions before further flight. Actions accomplished before the effective date of this AD in accordance with Avions de Transport Regional Service Bulletin ATR 42-28-0039, Revision 03, dated November 15, 2006, are considered acceptable for compliance with the corresponding action specified in this AD.
| Avions de Transport Regional service bulletin | Revision level | Date |
|---|---|---|
| ATR42-28-0039 (for Model ATR42 Airplanes) | 04 | June 12, 2007. |
| ATR72-28-1019 (for Model ATR72 Airplanes) | 05 | June 12, 2007. |
Note: This AD differs from the MCAI and/or service information as follows: The additional actions specified in the MCAI for operators that have done actions in accordance with previous issues of the service bulletins are not complete. Therefore, this AD only refers to Avions de Transport Regional Service Bulletins ATR 42-28-0039, Revision 03, dated November 15, 2006; Revision 04, dated June 12, 2007; and ATR 72-28-1019, Revision 05, dated June 12, 2007; as appropriate sources of service information for accomplishing the required actions. Operators that have done actions in accordance with previous issues of the service bulletins may request an approval for an alternative method of compliance (AMOC) according to paragraph (g) of this AD, provided that the AMOC provides an acceptable level of safety.
