Airspeed
indication - Airspeed fluctuations in icing conditions (ATA 34)
APPLICABILITY:
AIRBUS INDUSTRIE
A300, A310 and A300-600 aircraft, all certified models and all serial numbers.
REASONS:
Some operators
have reported several cases of sudden airspeed fluctuations indications in
cruise (CAS, TAS, MACH) experienced in severe icing conditions.
Flight crew must
adhere to the new Flight Manual "unreliable airspeed" procedure to
ensure the control of the flight path when an unreliable airspeed indication
occurs or in case of total loss of all airspeed indications.
ACTIONS:
The following
measures are rendered mandatory on the effective date of this Airworthiness
Directive:
Unless already
accomplished, adhering to the following revision numbers or higher revision
numbers of the Flight Manual ensures the compliance with this AD:
