AD No.: 2006 - 0278 

Date: 07 September 2006

No person may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the 

requirements of that Airworthiness Directive unless otherwise agreed with the Authority of the State of Registry.

Type Approval Holder’s Name: 

EUROCOPTER 

Type/Model designations: 

EC 130 helicopters 

TCDS Number: EASA.R.008 

Foreign AD: None 

Supersedes: DGAC F-2005-103 R1, EASA approval No. 2005-6113 

ATA 53 Fuselage – Cabin Vibration Dampers – Inspection / Modification 

Manufacturer: EUROCOPTER 

Applicability: EUROCOPTER EC 130 B4 helicopters equipped with cabin vibration 

damper blades, all part numbers, and having never been modified per 

modification 073565. 

Note: This Airworthiness Directive (AD) is intended for maintenance 

personnel and flight crews. 

Reason: This AD is issued following a case of a crack occurrence and a case of 

failure of a cabin vibration damper blade. 

In the event of failure of the blade of a cabin vibration damper assembly, the 

failed part can produce interference with a bellcrank of the flight controls, 

which could lead to jamming of a flight control. 

The purpose of this AD, which supersedes AD F-2005-103 R1, is: 

- to cover the replacement of Alert Telex No. 05A002 by an Alert 

Service Bulletin (ASB) with the same reference number and with no 

change to the technical content, 

 - to make the embodiment of modification 073565, which is 

introduced by ASB 53A008, mandatory. This modification consists 

in installing a cabin vibration damper restraining device to prevent 

any contact with the flight control components under the cabin floor, 

should a cabin vibration damper blade fail.
