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

Inspection / Repair

Manufacturer(s): EUROCOPTER (formerly EUROCOPTER Fr ance)

Applicability: EUROCOPTER EC 225 LP helicopters, al l serial numbers delivered before 15 December 2009, if equipped with FISHER H1 40 pilot’s and copilot’s seats Manufacturer Part/Number (MP/N) 05201 0032000D61091 (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 helicopter s, 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 washer s allowing installation of the countersunk head screws which attach the pil ot’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, a nd the accomplishment of the relevant corrective actions as necessary.
