(i) in production on Airbus A330, A330 freighter, and A380 airplanes;
(ii) in service by supplemental type certificate modification on:
(A) Airbus A319 and A320, and Bombardier CL-600-2B19 (Challenger 850), Boeing (formerly McDonnell Douglas) DC-9 series 80 airplanes; and
(B) Boeing 737-400 (BDSF), 767, and 747-8 airplanes.
We are adopting a new airworthiness directive (AD) for certain Siemens S.A.S. smoke detectors installed on various transport category airplanes. This AD requires inspection and replacement of the affected smoke detectors. This AD was prompted by a report that the affected smoke detectors failed an acceptance test. We are issuing this AD to correct the unsafe condition on these products.
(1) Within 30 days after the effective date of this AD, inspect each Siemens smoke detector, or review your maintenance records, to determine if an affected detector is installed.
(2) For smoke detectors identified in paragraph (c)(1) of this AD, replace the detectors within the compliance times specified in Figures 2, 3, and 4 to paragraph (f) of this AD.
| Manufacturing date (month/year) | Compliance time (after the effective date of this AD) |
|---|---|
| 122010 to 112011 inclusive | Within 5 months. |
| 122011 to 012013 inclusive | Within 11 months. |
| Manufacturing date (month/year) | Compliance time (after the effective date of this AD) |
|---|---|
| 032011 to 012012 inclusive | Within 5 months. |
| 022012 to 012013 inclusive | Within 11 months. |
| Manufacturing date (month/year) | Compliance time (after the effective date of this AD) |
|---|---|
| 112010 to 022012 inclusive | Within 24 months. |
| 032012 to 122012 inclusive | Within 36 months. |
(3) For smoke detectors identified in paragraph (c)(2) of this AD, replace the detectors within 5 months after the effective date of this AD.
After the effective date of this AD, do not install on any airplane a smoke detector:
(1) With a manufacturing date and P/N listed in Figure 2 or 3 to paragraph (f) of this AD;
(2) listed in Figure 4 to paragraph (f) of this AD unless the detector is marked `SIL PMC-26-002'.
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.
