Airworthiness Directives; de Havilland, Inc. DHC-6 Series 
Airplane; Correction

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: 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.

EFFECTIVE DATE: June 11, 1996.

FOR FURTHER INFORMATION CONTACT: Mr. John Dow, Aerospace Engineer, FAA, 
Small Airplane Directorate, 1201 Walnut, suite 900, Kansas City, 
Missouri 64106; telephone (816) 426-6934; facsimile (816) 426-2169.

SUPPLEMENTARY INFORMATION: On May 7, 1996, the Federal Aviation 
Administration (FAA) issued AD 96-09-11, Amendment 39-9587 (61 FR 
20616, May 7, 1996), which applies to de Havilland DHC-6 series 
airplanes. This AD requires a revision in the Airplane Flight Manual 
(AFM) by incorporating a warning into the Limitations Section of the 
AFM. Within this warning (in the first bullet paragraph) are cues for 
the pilot to follow during flight in severe icing conditions. The 
second cue references accumulation of ice on the upper surface of the 
wing aft of the protected area.

Need for the Correction

    The AD incorrectly references the ``upper surface of the wing'' 
instead of the lower surface of the wing. The de Havilland DHC-6 series 
airplanes are designed with the wings sitting high on the body of the 
airplane, which would not allow the pilot to visually check the upper 
surface of the airplane during flight without exiting the airplane.

Correction of Publication

    Accordingly, the publication of May 7, 1996 (61 FR 20616), of 
Amendment 39-9587; AD 96-09-11, which was the subject of FR Doc. 96-
10728, is corrected as follows:


Sec. 39.13  [Corrected]

    On page 20635, in the third column, Sec. 39.13, paragraph (a) (1) 
of the AD, the 19th line from the bottom of the column, correct ``--
Accumulation of ice on the upper surface'' to read ``--Accumulation of 
ice on the lower surface''.
    Action is taken herein to clarify this requirement of AD 96-09-11 
and to add this AD correction to Sec. 39.13 of the Federal Aviation 
Regulations (14 CFR 39.13).
    The effective date remains June 11, 1996.

    Issued in Kansas City, Missouri on May 17, 1996.

Manager, Small Airplane Directorate, Aircraft Certification Service.
