Airworthiness Directive · Amendment 39-21972 · Flight controls
The Boeing Company Airplanes
This AD applies to all The Boeing Company airplanes specified in paragraphs (c)(1) and (2) of this AD, certificated in any category.
(1) Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes.
(2) Model 737-8 and 737-9 airplanes.
The FAA is superseding Airworthiness Directive (AD) 2017-14- 13, which applied to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2017-14-13 required a torque check of the screws in the cover assembly of the heel rest for both the captain's and the first officer's rudder pedals, and corrective action if necessary. This AD was prompted by a report of an aborted takeoff because the rudder pedals were not operating correctly, and subsequent reports of loose rudder pedal cover fasteners on airplanes on which the actions required by AD 2017-14-13 were done and on additional airplanes that were not included in the applicability of AD 2017-14-13. This AD requires modifying the rudder pedal cover and shroud assemblies, and applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes and Model 737-8 and 737-9 airplanes. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued before the effective date of this AD: Within 27 months after the date of issuance of the original airworthiness certificate or original export certificate of airworthiness, or within 27 months after the effective date of this AD, whichever occurs later, determine whether the captain's and first officer's rudder pedal cover and shroud assemblies have been modified as specified in Boeing Alert Requirements Bulletin 737-27A1313 RB, Revision 1, dated June 24, 2020; or 737-27A1314 RB, Revision 2, dated July 6, 2021; as applicable, or has a production equivalent. A production equivalent can be determined by its upper cover assembly part numbers (P/Ns 251A3122-15 (pilot) and 251A3122-16 (first officer), or later approved part numbers) and shroud assembly part numbers (P/Ns 233A2319-5 or -6, or later approved part numbers, used for both pilot and first officer). A review of airplane maintenance records is acceptable for this requirement if the modification status can be conclusively determined from that review.
For airplanes that have not been modified as determined by paragraph (g) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-27A1313 RB, Revision 1, dated June 24, 2020, or Boeing Alert Requirements Bulletin 737-27A1314 RB, Revision 2, dated July 6, 2021, as applicable, except as specified by paragraph (i) of this AD, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-27A1313 RB, Revision 1, dated June 24, 2020; or Boeing Alert Requirements Bulletin 737-27A1314 RB, Revision 2, dated July 6, 2021; as applicable.
Note 1 to paragraph (h): Guidance for accomplishing the actions required by paragraph (h) of this AD can be found in Boeing Alert Service Bulletin 737-27A1313, Revision 1, dated June 24, 2020; and Boeing Alert Service Bulletin 737-27A1314, Revision 2, dated July 6, 2021; which are referred to in Boeing Alert Requirements Bulletin 737-27A1313 RB, Revision 1, dated June 24, 2020; and Boeing Alert Requirements Bulletin 737-27A1314 RB, Revision 2, dated July 6, 2021; respectively.
Where Boeing Alert Requirements Bulletin 737-27A1313 RB, Revision 1, dated June 24, 2020; and Boeing Alert Requirements Bulletin 737-27A1314 RB, Revision 2, dated July 6, 2021, use the phrase “the original issue date of” each Requirements Bulletin for compliance, 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.
