Required actions
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-32A1599 RB, dated October 14, 2025, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-32A1599 RB, dated October 14, 2025. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 737-32A1599, dated October 14, 2025, which is referred to in Boeing Alert Requirements Bulletin 737-32A1599 RB, dated October 14, 2025.
Unsafe condition
This AD was prompted by a report of a runway excursion caused by loss of braking. An inspection found that the right main landing gear (MLG) hydraulic hoses for the brakes were incorrectly installed (crossed) at the flow limiters, and the left MLG wheel speed transducer wires were also interchanged. The FAA is issuing this AD to address incorrectly installed brake hydraulic hoses for the MLG and wheel speed transducer wires for the MLG, which could cause incorrect antiskid system operation. The unsafe condition could result in loss of braking and a runway excursion with serious or fatal injuries.
Affected ADs
None.
