Deicing - Revision of Aircraft Flight Manual (ATA 04, 30)

 

1. APPLICABILITY:

 

ATR 72 aircraft models -101/ -102/ -201/ -202/ -211/ -212/ -212A.

 

2. REASON:

 

The purpose of this Airworthiness Directive (AD) is to modify the Aircraft Flight Manual so that the crew activate the wing and tail deicing system as soon as ice accretion is detected on the aircraft, and as long as this later is not exited from icing conditions.

 

This AD takes into account the requirements of FAA AD 99-19-10.

 

3. ACTIONS:

 

Within 15 days after the effective date of this AD, revise the approved Aircraft Flight Manual by incorporating the following modification. This may be accomplished by inserting a copy of this AD in the Aircraft Flight Manual.

 

- In chapter Normal Procedures - Icing conditions:

 

Replace the sentence "At first visual indication of ice accretion and as long as ice builds up on the airframe, the following procedure must be applied." by "At first visual indication of ice accretion and as long as atmospheric icing conditions exist, the following procedure must be applied".

 

Note: The following AFM's comply with the requirements of this AD:

-ATR 72-101, -102, -201, -202, -211, -212 models: Normal Revision No. 14 dated September 2000,

-ATR 72-212A model: Temporary Revision No. 11 dated October 2000.

 

REF.: Approved Aircraft Flight Manual.

           AD FAA 99-19-10.

 

EFFECTIVE DATE: FEBRUARY 03, 2001
