EASA EMERGENCY AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0059-E 

Date: 26 March 2010 

Note: This Emergency Airworthiness Directive (AD) is issued by EASA, acting in accordance 

with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States 

and of the European third countries that participate in the activities of EASA under Article 66 of 

that Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD unless otherwise specified by the Agency 

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]. 

Type Approval Holder’s Name :

ATA 65 Tail Rotor Drive – Tail Rotor Gearbox Assembly – 

 Inspection / Replacement / Re-identification 

Manufacturer(s): Agusta S.p.A. 

Applicability: A119 and AW119MKII helicopters, all serial numbers, if equipped with tail rotor 

90 ̊ gearbox (TGB) Part Number (P/N) 109-0440-06-103. 

Reason: A case of non-conformity has been discovered in the tail rotor 90 ̊ gearbox 

installed on an AW119MKII helicopter, where a bushing P/N 109-0135-14-101 

was missing. 

This condition, if not detected and corrected, could cause abnormal vibration 

of the tail rotor controls possibly leading to their damage and consequent loss 

of the yaw control function. 

For the above-mentioned reasons, this AD requires an inspection of the TGB 

assembly P/N 109-0440-06-103 to verify the installation of the bushing. 

If the bushing is not installed, this AD requires the replacement of the TGB 

assembly with serviceable parts, while if the bushing is found installed, this AD 

requires the re-identification of the TGB P/N by installing an additional 

nameplate. 

Effective Date: 29 March 2010
