Plain English Summary

2/10 complexity

What this does: This is a mandatory safety order (called an Airworthiness Directive) requiring the replacement of specific bolts and spring supports in the elevator control system of certain Embraer aircraft.

Who it affects: Owners and operators of Embraer EMB-110 (Bandeirante) aircraft with specific serial numbers listed in the document (ranging from 110001 to 110252, with several gaps).

What must be done: The elevator rear bellcrank bolts and spring supports must be replaced in accordance with Embraer Service Bulletin No. 110-27-038. This maintenance must be completed within 240 hours of flight time after 28 February 1981.

Why it matters: There was a reported incident overseas where a self-locking nut worked loose and fell off an elevator bellcrank bolt. If this happens in flight, it could compromise the elevator — the control surface that makes the aircraft climb or descend — potentially leading to loss of control.
