Airworthiness Directive · Amendment 39-21600 · Fuel
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 737-8 and 737-9 airplanes, certificated in any category, as identified in Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated June 2, 2020.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-8 and 737-9 airplanes. This AD was prompted by a report that during refueling of the right main tank, if there is a failure of the automatic shutoff system, the refueling panel does not provide the required indication that the automatic shutoff has failed. This AD requires installing a new fuel quantity processor unit (FQPU) and doing an FQPU software check. 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 times specified in the “Compliance” paragraph of Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated June 2, 2020, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated June 2, 2020.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Special Attention Service Bulletin 737-28-1363, dated June 2, 2020, which is referred to in Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated June 2, 2020.
Where Boeing Special Attention Requirements Bulletin 737-28-1363 RB, dated June 2, 2020, uses the phrase “the Original Issue date of Requirements Bulletin 737-28-1363 RB,” this AD requires using “the effective date of this AD.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
