Full official abstract
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.
This is a correction notice. The AD it corrects is not in our index yet, so we are showing the correction alone rather than implying we hold the directive itself.
