Superseded. A later AD replaced this one: AD 2004-14-24. Comply with the one in force.
Model EMB-120 series airplanes, certificated in any category; serial numbers 120004 and 120006 through 120355 inclusive; that have been modified in accordance with EMBRAER Service Bulletin 120-31-0039, 120-31-0040, 120-31-0041, or 120-31- 0042.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 series airplanes. This action requires measuring the gap between the bellcrank and the body of the rotary variable inductive transducers (RVITs) of the aileron and elevator, performing corrective action if necessary, and torquing the bolt that attaches the bellcrank to the RVIT shaft. This action is necessary to prevent restricted movement of the aileron or elevator, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
