Airworthiness Directive · Amendment 39-19564 · Life raft
Airbus Helicopters
Superseded. A later AD replaced this one: AD 2021-10-03. Comply with the one in force.
This AD applies Airbus Helicopters Model EC225 LP helicopters with a life raft installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP helicopters. This AD requires repetitive inspections of each life raft inflation cylinder percussion system bellcrank (bellcrank). This AD was prompted by reports of jammed bellcranks. The actions of this AD are intended to prevent an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Before further flight, and thereafter at intervals not to exceed 6 months:
(1) Clean each bellcrank and pivot link and inspect each bellcrank hole for corrosion. If there is any corrosion in a bellcrank hole:
(i) Remove the corrosion without exceeding a maximum depth of 0.1 millimeter (0.004 inch).
(ii) Clean each pivot link using 400-grain abrasive paper.
(iii) Apply corrosion protectant (Alodine 1200 or equivalent) to each bellcrank hole.
(2) Lubricate each bellcrank hole with grease before assembling the bellcrank.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
