## Summary

We propose to adopt a new airworthiness directive (AD) for all BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This proposed AD was prompted by reports of cracking of the main fitting of the nose landing gear (NLG). This proposed AD would require revising the maintenance program by incorporating a new safe-life limitation for the NLG main fitting. We are proposing this AD to prevent collapse of the NLG, which could lead to degradation of direction control on the ground or an un-commanded turn to the left and a consequent loss of control of the airplane on the ground, possibly resulting in damage to the airplane and injury to occupants.
