## Summary

The FAA is correcting a typographical error in an NPRM that was published in the Federal Register on September 14, 2005 (70 FR 54316). The error resulted in an incorrect Docket No. The NPRM applies to certain Bombardier Model DHC-8-400 series airplanes. The NPRM would require an inspection of the laminated shims for cracks, damage, or extrusion between the forward attachment fittings of the horizontal stabilizer and the top rib of the vertical stabilizer; a torque check of the attachment bolts in the attachment fittings of the front, middle, and rear spars; and corrective actions if necessary.
