AD NUMBER: 2006-07-26
SUBJECT: Airworthiness Directive 2006-07-26 Summary
FAA is adopting a new airworthiness directive (AD) for all
Aerospatiale Model ATR42 airplanes. This AD requires one-time
inspections to detect discrepancies (e.g., cracking, loose/sheared
fasteners, distortion) of the upper skin and rib feet of the outer
wing boxes, and repair if necessary.
This AD results from a report of cracking on the upper skin and
ribs of theouter wing box on an in-service airplane.
We are issuing this AD to detect and correct these
discrepancies, which could result in reduced structural integrity
of the airplane.
