This action makes a correction to Airworthiness Directive (AD) 96-09-11 concerning de Havilland DHC-6 series airplanes, which was published in the Federal Register on May 7, 1996 (61 FR 20616). That publication incorrectly references a cue for the pilot or crew member in severe icing conditions. The AD currently requires the pilot to follow certain visual cues during flight in icing conditions and the second of these cues requires the pilot to look at the upper surface of the wing. The word ``upper'' is wrong in the second cue. The intent of the AD in paragraph (a) (1), first bullet, second cue, is to require the pilot or crew member look at the ``lower'' surface of the wing. This action corrects the AD to reflect this change.
A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract
This amendment adopts a new airworthiness directive (AD) that applies to de Havilland DHC-6 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions, and to limit or prohibit the use of various flight control devices. This amendment is prompted by results of a review of the requirements for certification of the airplane in icing conditions, new information on the icing environment, and icing data provided currently to the flight crews. The actions specified by this AD are intended to minimize the potential hazards associated with operating the airplane in freezing rain or freezing drizzle conditions by providing more clearly defined procedures and limitations associated with such conditions.
