Airworthiness Directives; Jetstream Aircraft Limited Jetstream 
Models 3101 and 3201 Airplanes; Correction

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This action makes a correction to Airworthiness Directive (AD) 
96-09-17 concerning all Jetstream Aircraft Limited (Jetstream) Models 
3101 and 3201 airplanes, which published in the Federal Register on May 
7, 1996 (61 FR 20644). 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 lower surface of the wing. The word ``lower'' 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 to 
look at the ``upper'' 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 96-09-17, Amendment 39-9593 (61 FR 
20644, May 7, 1996), which applies to Jetstream Models 3101 and 3201 
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 bulleted paragraph) are cues for 
the pilot to follow during flight in severe icing conditions. The 
second cue references accumulation of ice on the lower surface of the 
wing aft of the protected area.

Need for the Correction

    The AD incorrectly references the ``* * *lower surface of the wing* 
* *'' instead of the upper surface of the wing. Jetstream Models 3101 
and 3201 airplanes are designed with the wings sitting low on the body 
of the airplane, which would not allow the pilot to visually check the 
lower surface of the wings on the airplane during flight without 
exiting the airplane.

Correction of Publication

    Accordingly, the publication of May 7, 1996 (61 FR 20644), of 
Amendment 39-9593; AD 96-09-17, which was the subject of FR Doc. 96-
10727, is corrected as follows:


Sec. 39.13  [Corrected]

    On page 20646, in the first column, Sec. 39.13, paragraph (a)(1) of 
the AD, line 26 from the top of the column, correct ``--Accumulation of 
ice on the lower surface'' to read ``--Accumulation of ice on the upper 
surface''.
    Action is taken herein to clarify this requirement of AD 96-09-17 
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.
