Models named: EC225LP. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Helicopters Model EC225LP helicopters, all manufacturer serial numbers, certificated in any category, equipped with emergency life rafts installed in the multi-purpose sponsons.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

For the purposes of this AD, the definitions specified in paragraphs (g)(1) through (4) of this AD apply. (1) Group 1: Helicopters that have an affected part installed. (2) Group 2: Helicopters that do not have an affected part installed. A helicopter that embodies Airbus Helicopters Modification 07 28457 in production is a Group 2 helicopter, provided the helicopter remains in that configuration. (3) Affected part: Life raft release bell cranks part number (P/N) 332A41-4396-20 (left-hand (LH) side) and P/N 332A41-4396-21 (right-hand (RH) side). (4) Serviceable part: Life raft release bell cranks P/N 332A41-4396-22 (LH) and P/N 332A41-4396-23 (RH).

Unsafe condition

This AD was prompted by reports of jammed bellcranks in the life raft inflation cylinder percussion system. The FAA is issuing this AD to address jammed bellcranks in the life raft jettison inflation cylinder percussion system. This condition could result in failure of a life raft to release in an emergency and subsequent injury to occupants.

Affected ADs

This AD replaces AD 2019-03-12, Amendment 39-19564 (84 FR 8250, March 7, 2019) (AD 2019-03-12).
