## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This proposed AD would require operators to modify the hydraulic control block of the nose landing gear. This proposed AD is prompted by a report of an unexpected steering event (swerve) during the take-off roll of one affected airplane. We are proposing this AD to prevent loss of airplane steering while on the ground, which could result in the airplane going off the side of the runway.
