Airworthiness Directive · Amendment 39-17995 · Rotorcraft flight control
Airbus Helicopters (Previously Eurocopter France) Helicopters
Superseded. A later AD replaced this one: AD 2022-03-13. Comply with the one in force.
This AD applies to Airbus Helicopters Model AS332L2 helicopters with a yaw control damper support (support) part number 332A25-1334-00 installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332L2 helicopters with a certain yaw control damper support (support) installed. This AD requires repetitively inspecting the support attachment points for a crack. This AD is prompted by a report that the front attachment points of several supports were found to have cracks. These actions are intended to detect a crack in a support, which could result in failure of the support, separation of the yaw damper unit, blocking of the yaw flight control channel, and reduced control of the helicopter.
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.
For helicopters with 3,900 hours time-in-service (TIS) or more, within 100 hours TIS and thereafter at intervals not exceeding 825 hours TIS, using a light source and a mirror, inspect each support at the four attachment points for a crack. If there is a crack, before further flight, replace the support.
