Unsafe condition
This AD was prompted by reports of damage to the wheel speed transducer wiring harness due to excessive slack in the wiring harness assembly that allows contact with the main landing gear tire and the determination that the airplane flight manuals (AFMs) and quick reference handbooks (QRHs) contain incorrect procedures for anti-skid braking system failures. The FAA is issuing this AD to prevent un-annunciated loss of normal brakes and reduced directional control during landing deceleration and ground operations, which could lead to a runway excursion.
Affected ADs
None.
