EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0030 

Date: 26 February 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].

TCDS Number : EASA R.002 

Foreign AD : Not Applicable 

Supersedure : None 

ATA 53 Fuselage – Pilot’s and Co-pilot’s Floor Attachment Screws – 

Inspection / Repair 

Manufacturer(s): EUROCOPTER (formerly EUROCOPTER France) 

Applicability: EUROCOPTER EC 225 LP helicopters, all serial numbers delivered 

before 15 December 2009, if equipped with FISHER H140 pilot’s and copilot’s seats Manufacturer Part/Number (MP/N) 052010032000D61091 

(EUROCOPTER Part/Number (P/N) 704A41120116) or with

EUROCOPTER co-pilot’s seats MP/N 332V08-0180-00. 

Reason: On several newly produced EC 225 helicopters, some missing screws and 

nuts attaching the floors under the pilot’s and co-pilot’s seats have been 

identified. 

Investigation has shown that some of the cup washers allowing installation 

of the countersunk head screws which attach the pilot’s and co-pilot’s floor 

to the frames were missing. 

This condition, if not corrected, reduces the seat attachments strength and 

it could result in no longer retaining the seats in place in the event of 

emergency or hard landing. 

For the reasons stated above, this AD requires the inspection of the pilot’s 

and co-pilot’s floor attachments under the seats, and the accomplishment 

of the relevant corrective actions as necessary.

Effective Date: 12 March 2010
