14 CFR Part 39

[Docket No. FAA-2004-20007; Directorate Identifier 2004-CE-50-AD; 
Amendment 39-14798; AD 2006-23-09]

Airworthiness Directives; Air Tractor, Inc. Model AT-602 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document makes a correction to Airworthiness Directive 
(AD) 2006-23-09, which published in the Federal Register on November 9, 
2006 (71 FR 65719), and applies to all Air Tractor, Inc. Model AT-602 
airplanes. AD 2006-23-09 requires you to repetitively inspect (using 
the eddy current method) the wing center splice joint two outboard 
fastener holes on both of the wing main spar lower caps for fatigue 
cracking; repair or replace any wing main spar lower cap where fatigue 
cracking is found; and report any fatigue cracking found. This AD 
results from fatigue cracking at the wing center splice joint outboard 
fastener hole in one of the wing main spar lower caps. The AD number in 
the AD is incorrectly referenced as ``2006-23-01'' instead of ``2006-
23-09'' in two places. This document corrects these references.

DATES: The effective date of this AD (2006-23-09) remains December 14, 
2006.

Discussion

    On October 26, 2006, the FAA issued AD 2006-23-09, Amendment 39-
14798 (71 FR 65719, November 9, 2006), which applies to Air Tractor, 
Inc. Model AT-602 airplanes. AD 2006-23-09 requires you to repetitively 
inspect (using the eddy current method) the wing center splice joint 
two outboard fastener holes on both of the wing main spar lower caps 
for fatigue cracking; repair or replace any wing main spar lower cap 
where fatigue cracking is found; and report any fatigue cracking found.
    The AD number in the AD is incorrectly referenced as ``2006-23-01'' 
instead of ``2006-23-09'' in two places.

Need for the Correction

    This correction is needed to assure that the airplane records and 
documentation shows that the applicable AD is complied with.

    Accordingly, the publication of November 9, 2006 (71 FR 65719), of 
Amendment 39-14798; AD 2006-23-09, which was the subject of FR Doc. 06-
18688, is corrected as follows:

Section 39.13 [Corrected]

    On page 65721, in the first column and fourth line, replace ``2006-
23-01'' with ``2006-23-09.''
    Action is taken herein to correct this reference in AD 2006-23-09
