Federal Aviation Administration May 19, 2006 – Federal Register Recent Federal Regulation Documents

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 757-200, -200CB, and -300 series airplanes. The original NPRM would have required repetitive detailed inspections for proper functioning of the girt bar leaf springs for the escape slides to ensure the leaf springs retain the sliders and the required 0.37-inch minimum engagement between the sliders and floor fittings is achieved at passenger doors 1, 2, and 4, and corrective actions if necessary. The original NPRM resulted from a report that the escape slides failed to deploy correctly during an operator's tests of the escape slides. This action revises the original NPRM by stating that this proposed AD would not include procedures from the airplane maintenance manuals and component maintenance manuals that allow bending the girt bar retention springs. We are proposing this supplemental NPRM to prevent escape slides from disengaging from the airplane during deployment or in use, which could result in injuries to passengers or flightcrew.

This document makes a correction to Airworthiness Directive (AD) 2006-10-07. That AD applies to Hamilton Sundstrand Model 14RF-9 propellers. We published AD 2006-10-07 in the Federal Register on May 12, 2006 (71 FR 27600). An incorrect phrase was used in the compliance section, which impacts the intent of the compliance. This document corrects that phrase. In all other respects, the original document remains the same.
