Airworthiness Directive · Amendment 39-22918 · Water/waste
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 767-200, -300, and -400ER series airplanes, as identified in Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023, excluding the airplanes that were converted by STC number ST02040SE to freighter configuration where the subject hoses were removed.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. This AD was prompted by a report of multiple engine indicating and crew alerting system messages during potable water servicing after the water leaked onto the electronics equipment cooling air filter. This AD requires installation of hoseducts around the left-side section 43 potable water supply hoses and connections, a potable water system leakage test, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable time specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 767-38A0076, dated December 1, 2023, which is referred to in Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023.
(1) Where the Boeing Recommended Compliance Time columns of the tables in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023, refer to “the Original Issue date of Requirements Bulletin 767-38A0076 RB,” this AD requires using the effective date of this AD.
(2) Where step 5 of figures 11 and 13 in Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 2023, refers to the part name “spacers for bolts,” this AD requires replacing that text with “spacer for bolt.”
