Models named: 717-200. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 717-200 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025.

Compliance

Comply with this AD within the compliance times specified, unless already done.

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 717-32A0043 RB, dated February 12, 2025, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 717-32A0043, dated February 12, 2025, which is referred to in Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025.

Unsafe condition

This AD was prompted by a report of a Boeing Model 717-200 operator that experienced a nose landing gear-up landing caused by the failure of the upper lock link assembly. The unsafe condition, if not addressed, could result in a failure of the nose landing gear (NLG) to fully extend during landing or cause the nose gear to remain retracted while the main gear deploys. Additionally, it could restrict ground maneuverability, increasing the risk of a runway excursion.

Affected ADs

None.
