The FAA is adopting a new airworthiness directive (AD) for Kidde Aerospace & Defense cargo fire extinguisher halon bottles installed on various transport category airplanes. This AD was prompted by a report indicating that certain cargo fire extinguisher halon bottles installed in the cargo compartment had low charge pressure. This AD requires an inspection to determine the part number and serial number of the cargo fire extinguisher halon bottles and replacement of affected parts with serviceable parts. The FAA is issuing this AD to address the unsafe condition on these products.
For this AD, the definitions specified in paragraphs (g)(1) through (3) of this AD apply.
(1) Group 1: Boeing Model 737-8 and 737-9 airplanes, and Model 737-700, 737-800, and 737-900ER series airplanes.
(2) Group 2: Transport category airplanes other than those identified as group 1. (3) Affected part: A cargo fire extinguisher halon bottle, manufactured by Kidde Aerospace & Defense, having a part number and serial number that is identified in the service information identified in paragraphs (c)(1)(i) and (ii) of this AD.
Note 1 to paragraph (g)(3): The terms “cargo fire extinguisher halon bottles” and “fire extinguishers” are used interchangeably in this AD and the service information identified in paragraphs (c)(1)(i) and (ii) of this AD, and in paragraphs (i)(1)(i) and (ii) of this AD.
Within 24 months after the effective date of this AD, do an inspection to determine the part number and serial number of the cargo fire extinguisher halon bottles installed in the cargo compartment. A review of maintenance records can be done in lieu of the inspection provided the part number and serial number of the cargo fire extinguisher halon bottles can be conclusively determined from that review.
If, during the inspection or records review required by paragraph (h) of this AD, it is determined that an affected part, as identified in paragraph (g)(3) of this AD, is installed, before further flight, replace the part with a serviceable part in accordance with the applicable service information identified in paragraph (i)(1) and (2) of this AD.
(1) For group 1 airplanes as identified in paragraph (g)(1) of this AD: The Accomplishment Instructions of the service information identified in paragraph (c)(1)(i) of this AD, or the service information identified in paragraph (i)(1)(i) or (ii) of this AD, as applicable.
(i) Boeing Alert Requirements Bulletin 737-26A1150 RB, dated September 27, 2019.
(ii) Boeing Alert Requirements Bulletin 737-26A1151 RB, dated September 27, 2019.
(2) For group 2 airplanes as identified in paragraph (g)(2) of this AD: The Accomplishment Instructions of the service information identified in paragraph (c)(1)(i) or (ii) of this AD, as applicable.
As of the effective date of this AD, no person may install on any airplane an affected part as identified in paragraph (g)(3) of this AD unless that part has a circled letter “G” stamped at a distance of approximately one inch from the left edge of the placard, indicating that the cargo fire extinguisher halon bottle has been tested and refilled.
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.
