EASA SIB SAIB-2026-02: Elevator Tab Control System

What to do

Owners and operators of Textron Aviation Inc. Model 1900D airplanes with serial numbers UE-2 through UE-423 should inspect and modify the elevator trim tab actuators in accordance with Raytheon Aircraft Service Bulletin 27-3032 dated July 2003. Although this SAIB does not impose mandatory compliance deadlines, following the recommended service bulletin will help mitigate the risk of elevator trim actuator freezing. For further guidance, stakeholders may contact the FAA or Textron Aviation customer service.

Summary

The Special Airworthiness Information Bulletin SAIB 2026-02 is an FAA advisory concerning the elevator tab control system on Textron Aviation Inc. Model 1900D airplanes, including those registered under previous type certificate holders such as Beechcraft Corporation and Raytheon Aircraft Company. It addresses a potential airworthiness concern related to the elevator pitch trim actuator that may experience water ingress and freezing, leading to pitch trim jams during flight.

What changed

SAIB 2026-02 highlights an airworthiness concern involving water freezing in the elevator trim actuator of Model 1900D airplanes, which can cause pitch trim jams and autopilot trim failures. It references a previously issued Raytheon Service Bulletin 27-3032 from July 2003 that specifies modifications to the elevator trim tab actuators to prevent water ingress and freezing. The bulletin does not mandate regulatory action but recommends compliance with the service bulletin.

Why it matters

This information is important for aviation professionals because elevator pitch trim actuator malfunctions can affect flight safety by causing pitch control issues and autopilot failures. Operators and maintenance personnel need to be aware of the risk of water ingress and freezing in the elevator trim system to prevent in-flight pitch upset events. Understanding and implementing the recommended modifications can enhance aircraft reliability and reduce the likelihood of service difficulties related to the elevator trim system.
