Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Goodrich evacuation systems approved under TSO-C69, TSO- C69a, TSO-C69b, and TSO-69c, installed on certain Boeing, McDonnell Douglas, and Airbus transport category airplanes. For certain systems, this proposed AD would require replacing the evacuation systems shear- pin restraints with new ones. For certain other systems, this proposed AD would require an inspection for manufacturing lot numbers; and a general visual inspection of the shear-pin restraint for discrepancies, and corrective actions if necessary. This proposed AD is prompted by 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 during the evacuation.
