Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) airplanes. This AD requires an inspection of the manufacturer's date code on certain electrical relays to identify defective Leach TDH- series electrical relays and replacement of identified relays. This AD results from a report of defective electrical relays affecting emergency equipment. We are issuing this AD to prevent the malfunction of emergency equipment (the passenger oxygen system, the thrust reverse control system, and the auxiliary power unit fire detection, warning, and extinguishing system) during an emergency.
