This AD applies to the airplanes listed in Table 1 of this AD, certificated in any category:
| Model | Line numbers |
|---|---|
| 737-200, -200C, -300, -400, and -500 series airplanes | 311 through 3132 inclusive. |

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-200, -200C, -300, -400, -500, -600, -700, - 700C, -800, and -900 series airplanes. This AD requires a one-time detailed inspection for discrepancies of the secondary fuel vapor barrier of the wing center section, and related investigative/ corrective actions if necessary. This AD is prompted by reports that the secondary fuel vapor barrier was not applied correctly to, or was missing from, certain areas of the wing center section. We are issuing this AD to prevent fuel or fuel vapors from leaking into the cargo or passenger compartments and coming into contact with a possible ignition source, which could result in fire or explosion.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of the following service bulletins, as applicable:
(1) For Model 737-200, -200C, -300, -400, and -500 series airplanes: Boeing Special Attention Service Bulletin 737-57-1261, dated February 27, 2003; and
(2) For Model 737-600, -700, -700C, -800, and -900 series airplanes: Boeing Special Attention Service Bulletin 737-57-1250, Revision 1, dated September 4, 2003.
Within 48 months after the effective date of this AD, do a one-time detailed inspection for discrepancies of the secondary fuel vapor barrier of the wing center section; and if discrepancies exist, before further flight, do any applicable related investigative/corrective actions in accordance with the Accomplishment Instructions of the applicable service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
Actions accomplished before the effective date of this AD in accordance with Boeing Special Attention Service Bulletin 737-57-1250, dated February 7, 2002, are considered acceptable for compliance with the corresponding actions specified in paragraph (g) of this AD.
