Airworthiness Directive · Amendment 39-18461 · Ice and rain protection
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013.
We are superseding Airworthiness Directive (AD) 2013-26-08 for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 required inspecting the orientation of both sides of the coil cord connector keyways of the number 2 windows on the flight deck; re-clocking the connector keyways, if necessary; and replacing the coil cord assemblies on both number 2 windows on the flight deck. This new AD adds airplanes to the applicability. AD 2013-26-08 resulted from reports of arcing and smoke at the left number 2 window in the flight deck. This AD was prompted by a determination that additional airplanes are subject to the same identified unsafe condition. We are issuing this AD to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.
This paragraph restates the requirements of paragraph (g) of AD 2013-26-08, with no changes. For airplanes identified as Group 1, Configuration 1, in Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013: Within 48 months after February 10, 2014 (the effective date of AD 2013-26-08), do the actions specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Do a general visual inspection of the orientation of the coil cord connector keyways on the captain's and first officer's sides of the flight compartment, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, except as specified in paragraph (k) of this AD. If the orientation is not at the specified position, before further flight, turn the receptacle connector to the correct position, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, except as specified in paragraph (k) of this AD.
(2) Replace the coil cords with new coil cords on both sides of the flight deck, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, except as specified in paragraph (k) of this AD.
This paragraph restates the requirements of paragraph (h) of AD 2013-26-08, with no changes. For airplanes identified as Group 1, Configuration 2, and Group 2, Configuration 1, in Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013: Within 48 months after February 10, 2014 (the effective date of AD 2013-26-08), install the receptacle connector with changed keyway position on both sides of the flight deck, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, except as specified in paragraph (k) of this AD.

If any rubbing damage is found: Before further flight, replace the coil cord with a new coil cord, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, except as specified in paragraph (k) of this AD.

In the circuit breaker tables of the Work Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, the panel number for circuit breaker C00393 is incorrectly identified as “P6-12.” The correct panel number reference for circuit breaker C00393, “WINDOW HEAT POWER RIGHT SIDE,” is P6-11.

The correct description for Part 3 of the Work Instructions is “PART 3: COIL CORD INSPECTION AND REPLACEMENT IF DAMAGE IS FOUND.”
(3) This paragraph restates the provisions of paragraph (j)(3) of AD 2013-26-08, with no changes. In Figures 13 and 14, in paragraph 3.B. of the Work Instructions of Boeing Special Attention Service Bulletin 737-30-1058, Revision 5, dated April 24, 2013, the note before the step tables misidentifies certain parts and airplane groups.
