## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and Model 767-200 and -300 series airplanes equipped with certain Goodrich evacuation systems. For certain airplanes, this proposed AD would require replacing the evacuation systems shear-pin restraints with new ones. For certain other airplanes, this proposed AD would require an inspection for manufacturing lot numbers; and a general visual inspection of the shear-pin restraints for discrepancies, and corrective actions if necessary. This proposed AD results from several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are proposing this AD to prevent failure of the evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew duringthe evacuation.
