BRAZILIAN AIRWORTHINESS DIRECTIVE 

AD No.: 2014-09-01 Effective Date: 04 Sep. 2014 

The following Brazilian Airworthiness Directive (AD) , issued by the Ag~ncia Nacional de Avia9ao Civil (ANAC) in accordance with provisions of Chapter IV, Ti tle III of C6digo Brasileiro de Acronautica - Law No. 

7, 565 dated 19 December 1986 - and Regulamento Brasileiro da Aviayao Civil (RBA.C) 39, applies to all aircraft registered in the Registro Aeron~utico Brasilciro. No person may operat e an aircraft to which this AD applies, unless it has previously complied with the requirements established herein. 

AD No. 2014-09-01 - EMBRAER S.A. I 39-1387. 

APPLICABILITY: 

This Airworthiness Directive is applicable to Embraer S.A. EMB- 110, EMB-II OC, 

EMB-IIOE, EMB-l lOF, EMB-l lOP, EMB-11081, EMB-llOSI, EMB-1 10P2, EMB-liOKl e EMBIIOPI airplanes; all serial numbers. 

CANCELLATION I REVISION: 

Not applicable. 

REASON: 

This AD was prompted by a report of an in-service occurrence were an EMB-1 I 0 

airplane performed a forced landing, due to a strong vibration felt by the pilots after the takeoff. The 

investigation determined that the cause of the vibration most likely resulted from a broken fork end on the 

rudder trim tab actuator that connects the trim tab to the trim tab actuator due to severe corrosion. We are 

issuing this AD to detect and correct corrosion and cracking on the rudder trim tab actuator terminal, 

which could cause the terminal to fa il and result in loss of control of the airplane. 

Since this condition may exist in other airplanes of the same type and affects flight 

safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance 

with this AD in the indicated time limit without prior notice. 

REQUIRED ACTION: 

Inspection of the rudder trim tab actuator components. 

COMPLIANCE: 

Do the actions required by this AD within the compliance times specified, unless the 

actions have already been done. 

Repetitive Inspections and Corrective Actions 

(a) Within 10 flight hours or 15 days after the effective date of this AD, whichever occurs 

first, do a detailed inspection (DI) to detect discrepancies and corrosion on the Rudder Trim Tab Actuator 

components, and if any discrepancy exists, repair before further flight; in accordance with the 

Accomplishment Instructions of Embraer Alert Service Bulletin (ASB) II0-27-A095, original issue, 

dated August 2 1, 2014. Repeat the detailed inspection required by this paragraph thereafter at intervals 

not to exceed 60 months. 

Material Incorporated by Reference 

(b) You must use Embraer ASB II0-27-A095, original issue, dated August 21, 20 14, or 

further revisions approved by the ANAC, to do the actions required by this AD, unless this AD specifies 

otherwise.
