EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0258 

Date: 06 December 2010 

Note: This 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 Airworthiness Directive applies, except in accordance with the requirements of that Airworthiness Directive 

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 : 

EUROCOPTER 

Type/Model designation(s) : 

EC130 B4 Helicopters 

TCDS Number : EASA R.008 

Foreign AD : Not applicable. 

Supersedure : This AD supersedes AD 2007-0219-E, dated 24 August 2007 

ATA 56 Windows – Centre Windshield – Inspection/ Operating Limitation 

/ Replacement 

Manufacturer(s): Eurocopter (formerly Eurocopter France, Aerospatiale) 

Applicability: EC 130 B4 helicopters, all serial numbers, except those modified in 

accordance with EUROCOPTER MOD 07 3590, approved on 08 April 2009. 

Reason: Following report failures of the centre windshield panel in flight the 

investigations have revealed that this failure was caused by a crack which 

started in the blending radius between the lower and upper sections of the 

windshield. 

This unsafe condition, if not detected and corrected, could lead to serious 

injury of the helicopter occupants. 

For the reasons described above, EASA issued Emergency AD 2007-0219-

E on 24 August 2007 that required a pre-flight inspection of the centre 

windshield, repair or replacement (with ones of same design) of cracked 

windshields and an airspeed limitation when in-flight distortion of the 

windshield had been observed. 

On 08 April 2009 a modification ref. MOD 07 3590 of the EC130B4 centre 

windshield was approved by EASA. This modification incorporated a centre 

windshield panel Part Number P/N 350A259045.20 of new design. 

Installation of MOD 07 3590 proved to eliminate the possibility of centre 

windshield cracks thus providing an alternative terminating action for the 
EASA AD No.: 2010-0258

preflight inspection. 

While still requiring the pre-MOD 07 3590 centre windshield panels pre-flight 

inspection, this AD is being issued to require installation of the modified 

centre windshield after a crack was detected, as well as to unify actions 

mandated by AD 2007-0219-E to be taken following the crack detection. 

Note: P/No’s of the pre-MOD 07 3590 centre windshield panels are the 

following: 350A259025.00, 350A259004.00, and 350A259041.20. 

Effective Date: 20 December 2010 

Required Action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously: 

(1) Before next flight after 28 August 2007 (the effective date of AD 2007-0219-

E) and thereafter prior to each flight, visually inspect the centre windshield 

panel for cracks in accordance with the instructions of paragraph 2.B.1 of 

EUROCOPTER EC130 B4 Alert Service Bulletin (ASB) No. 05A005. 

(2) If a crack is found, before next flight, replace the centre windshield in 

accordance with the instructions of ASB No. 05A005 Revision 2. 

(3) Repair or replacement in accordance with ASB No. 05A005 Revision 1, 

prior to the effective date of this AD, is acceptable to comply with the 

requirements of paragraph (2) of this AD. 

(4) If distortion of the centre windshield is detected in flight reduce the airspeed 

immediately to 70 KIAS or below. 

(5) If distortion of the centre windshield has been detected during flight, 

accomplish the following: 

(5.1) Before next flight, install a placard on the instrument panel, in full view 

of the pilot, indicating the 70 KIAS airspeed limitation, in accordance 

with the instructions of paragraph 2.B.2 of the ASB No. 05A005 and, 

after the effective date of this AD, insert in the Flight Manual specific 

pages with the temporary airspeed limitation provided in Appendix 

paragraph 4 of the ASB No. 05A005 Revision 2; 

(5.2) Within the next 50 flight hours or 15 days, whichever occurs first after 

distortion detection, replace the centre windshield panel with P/N 

350A259045.20 in accordance with the instructions of paragraph 2.B.3 

of the ASB No. 05A005, Revision 2. 

(5.3) After the replacement of the windshield as required by paragraph (5.2) 

remove the placard as well as the Flight Manual specific pages 

addressed in paragraph (5.1). 

(6) Modification of a helicopter by replacing a centre windshield panel with P/N 

350A259045.20 either as required by paragraph (5.2) or as an option, 

constitutes terminating action for the repetitive inspections as required by 

paragraph (1) of this AD for that helicopter.
