Support at First Officer Position
12/2002
Applicability: Model 737-100, -200, -200C, -300, -400, and -500 series aircraft, line numbers 1
through 3132.
Requirement: Inspect in accordance with the technical requirements of FAA AD 2002-18-02 Amdt 39-12874.
Note: Boeing Alert Service Bulletin 737-27A1238 refers.
Compliance: As specified in the Requirement document.
This Airworthiness Directive becomes effective on 28 November 2002.
Background: This Directive requires a one-time inspection to determine whether the lo wer bearing support of the aileron transfer mechanism directly below the first officer’s control column has a ‘pocket’, and follow-on corrective actions, if necessary. The actions specified by this Directive are intended to prevent jamming of the first officer’s control wheel due to the presence of a foreign object on the lower bearing support of the transfer mechanism, which could result in reduced controllability of the aeroplane.
