Models named: G-1159B. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Gulfstream Model G-1159B airplanes, certificated in any category. Note 1 to paragraph (c) of this AD: Model G-1159B airplanes are also referred to by marketing designation GIIB.

Compliance

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

Required actions

Within 12 months after the effective date of this AD, do an inspection to determine the part number of the rudder assembly, in accordance with the Accomplishment Instructions of Gulfstream GII/IIB Customer Bulletin Number 468, dated February 17, 2016, except as provided by paragraph (i)(1) of this AD. If the rudder assembly does not have P/N 1159CS20004-3, within 12 months after the effective date of this AD, verify that the rudder assembly part number recorded in the aircraft maintenance records matches the part number of the rudder assembly installed on the airplane and if the rudder assembly part number does not match, correct the aircraft maintenance records accordingly.

Unsafe condition

This AD was prompted by a review of airplane maintenance records, which revealed that incorrect rudder assemblies were installed on certain airplanes. We are issuing this AD to detect and correct the installation of incorrect rudder assemblies, which could result in flutter and subsequent loss of the rudder, and consequent loss of control of the airplane.

Affected ADs

None.
