## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This proposal would require a review of airplane maintenance records and an inspection of the nose landing gear (NLG) to determine the part number of the steering pinion, and follow-on/corrective actions as applicable. The actions specified by the proposed AD are intended to prevent failure of the steering pinion in the NLG, which could result in loss of steering and possible damage to the airplane during takeoff and landing. This action is intended to address the identified unsafe condition.
