Airworthiness Directive · Amendment 39-18957 · Equipment and furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2022-06-06. Comply with the one in force.
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 Alert Service Bulletin 737-25A1732, Revision 2, dated April 13, 2017.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report of an aborted takeoff because the rudder pedals were not operating correctly. Investigation revealed a protruding screw in the rudder pedal heel rest adjacent to the pedals. This AD requires a torque check of the screws in the cover assembly of the heel rest for both the Captain and the First Officer's rudder pedals, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.
Within 21 months after the effective date of this AD: Do a one-time torque check of the screws in the cover assembly of the heel rest for both the Captain and the First Officer's rudder pedals, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737-25A1732, Revision 2, dated April 13, 2017.
If the results of the torque check required by paragraph (g) of this AD indicate that any screw does not hold torque to the required value, before further flight, replace the affected screw and associated nutplate, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737-25A1732, Revision 2, dated April 13, 2017.
This paragraph provides credit for the actions specified in paragraphs (g) and (h) of this AD, if those actions were performed before the effective date of this AD using Boeing Alert Service Bulletin 737-25A1732, Revision 1, dated August 15, 2016.
