– Inspection / Replacement

Manufacturer(s): Eurocopter (for merly EUROCOPTER France) Applicability: SA 365 N, SA 365 N1, AS 365 N2, AS 365 N3, EC 155 B, EC 155 B1, AS 332 C, AS 332 C1, AS 332 L, AS 332 L1, AS 332 L2 and EC 225 LP helicopters, all serial numbers, when equipped with EADS SOGERMA pilot seat Part Numb er (P/N) 2510106

- 00 with serial number between 720 (inclusive) and 1451 (inclusive).
Reason: During a maintenance inspection, it was found that a weld bead was missing on the rear beam of a pilot seat supplied by EADS SOGERMA. The a nalysis has shown that this non

- conformity, wh ich impairs the seat anti

- crash function, may be present on a limited number o f seats installed on Eurocopter helicopters. This condition, if not detected and corrected, cou ld lead to pilot injury in case of h elicopter hard landing following an emergency. To address this unsafe condition, EASA issued AD 2012

- 0084 to require inspection of the fligh t crew seats, and replacement of any seat found improperly welded. This AD also required marking of all correctly we lded seats. Since issuance of EASA AD 2012

- 0084, it was discovered that a weld bead was missing on another part of the seat rear beam that was not required to be inspected

. To ensure that any welding discrepancy is detected and corrected, Eurocopter Alert Service Bulletin s (ASB) A S365

- 25.01.18, ASB EC155

- 25A114, ASB AS332

- 25.02.49 and ASB EC225
