Models named: 737-600, -700, -800, -900ER series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to The Boeing Company Model 737-600, -700, -800, and -900ER series airplanes, certificated in any category, identified in Boeing Special Attention Service Bulletin 737-28-1303, dated April 26, 2012.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 60 months after the effective date of this AD, do a detailed inspection for part number (P/N) TA0930034-10 wire support clamp at the locations specified in Figures 1 through 4 of Boeing Special Attention Service Bulletin 737-28-1303, dated April 26, 2012, and do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1303, dated April 26, 2012, except as provided by paragraph (h) of this AD. Do all applicable related investigative and corrective actions before further flight.

Unsafe condition

This AD was prompted by incorrect wire support clamps installed within the left environmental control systems (ECS) bay, which could allow wiring to come in contact with the exposed metal of the improper clamp. We are issuing this AD to prevent electrical arcing and a potential ignition source within the ESC bay, which in combination with flammable fuel vapors, could result in a center wing fuel tank explosion, and consequent loss of the airplane.

Affected ADs

None.
