Models named: AS332C, AS332C1, AS332L, AS332L1. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters, certificated in any category.

Compliance

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.

Required actions

Affected parts are attachment screws and fitting(s) fastening the parts identified in paragraphs (g)(1) and (2) of this AD. (1) Rear MGB suspension bars, right and left sides, to the fuselage. (2) Front MGB suspension bar to the fuselage.

Unsafe condition

This AD was prompted by reports of corrosion on attachment screws and fittings fastening the main gearbox (MGB) suspension bars to the fuselage. The FAA is issuing this AD to address corrosion on attachment fittings and attachment screws for the MGB suspension bars. This condition, if not addressed, could lead to structural failure of the MGB attachment screws, resulting in detachment of MGB suspension bars from the fuselage and subsequent loss of control of the helicopter.

Affected ADs

None.
