Airworthiness Directive · Amendment 39-14905 · Boeing Model 767-200 and -300 Series Airplanes
Boeing Model 767-200 and -300 Series Airplanes
This AD applies to Boeing Model 767-200 and -300 series airplanes, certificated in any category, as identified in Boeing Service Bulletin 767-30A0038, Revision 2, dated February 23, 2006.
Note 1: For the purposes of this AD: An open cargo floor configuration, as identified in Boeing Service Bulletin 767-30A0038, is a floor without panels installed between all roller trays in the cargo compartment. A closed cargo floor configuration, as identified in Boeing Service Bulletin 767-30A0038, is a floor with panels installed between all roller trays in the cargo compartment.
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD currently requires an inspection of visually accessible areas for indications of overheating of the heater tape attached to the potable water fill and drain lines in the forward and aft cargo compartments, exposed foam insulation or missing or damaged protective tape around the potable water fill and drain lines, and debris or contaminants on or near the potable water fill and drain lines. That AD also requires corrective action, as necessary. This new AD requires repetitive inspections of the forward and aft cargo compartments, as applicable, for discrepancies of the potable water supply and gray water drain lines; and applicable corrective actions if necessary. This AD also requires replacing the heater tapes on the potable water supply and gray water drain lines of the forward and aft cargo compartments, as applicable, with new ribbon heaters, or deactivating and removing any defective heater tape and wrapping the drain line with foam insulation; either action ends the repetitive inspections. This AD results from a report of a fire in the aft cargo compartment. We are issuing this AD to prevent overheating of the heater tape on potable water fill and drain lines, which may ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 18 months since the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness, or within 90 days after the effective date of this AD, whichever is later: Do the actions in Table 1 of this AD in accordance with the Accomplishment Instructions of Boeing Service Bulletin 767-30A0038, Revision 2, dated February 23, 2006.

|---|---|---|
| (1) Foreign object debris (FOD) or contamination on, near, or around the potable water supply and gray water drain lines | 600 flight hours | Paragraph (h)(1) or (h)(2) of this AD are done. |
| (2) Indications of heat damage, exposed foam insulation, or missing or damaged protective tape of all heater tape on the potable water supply and gray water drain lines | 1,800 flight hours | Paragraph (h)(1) or (h)(2) of this AD are done. |
If any discrepancy identified in Table 1 of this AD is found during any general visual inspection required by either paragraph (f)(1) or (f)(2) of this AD, before further flight, do the applicable corrective action by accomplishing all the actions in accordance with the Accomplishment Instructions of Boeing Service Bulletin 767-30A0038, Revision 2, dated February 23, 2006.
At the applicable compliance time specified in Table 2 of this AD: Perform the actions required by paragraph (h)(1) or (h)(2) of this AD, in accordance with the Accomplishment Instructions of Boeing Service Bulletin 767-30A0038, Revision 2, dated February 23, 2006. Accomplishing the requirements of paragraph (h)(1) or (h)(2) of this AD ends the requirements of paragraph (f) of this AD.
(1) Replace the heater tapes on the potable water supply and gray water drain lines of the forward and aft cargo compartments, as applicable, with Adel Wiggins ribbon heaters.
(2) Deactivate and remove any defective heater tape(s) from the potable water supply and gray water drain line(s) of the forward and aft cargo compartments and wrap the drain line(s) with foam insulation.
| For airplanes on which the heater tape— | The compliance time is— |
|---|---|
| Has not been replaced in accordance with Boeing Alert Service Bulletin 767-30A0037, dated May 28, 2002; or Boeing Service Bulletin 767-30A0037, Revision 1, dated July 19, 2002; as of the effective date of this AD | Within 42 months since the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness, or within 24 months after the effective date of this AD, whichever occurs later. |

(i) For airplanes having variable number (VN) VN471 and VN472: Actions done in the forward cargo compartment before the effective date of this AD in accordance with Boeing Alert Service Bulletin 767-30A0038, dated December 16, 2004; or Boeing Service Bulletin 767-30A0038, Revision 1, dated September 29, 2005; are acceptable for compliance with the corresponding requirements of this AD for the forward cargo compartment only.
