The Navy and Marine Corps are planning to replace a potentially defective part used in pilot ejection in some aircraft like Super Hornets and T-45C training aircraft and grounding some planes as part of the process. The Navy was notified of a potential defect on the cartridge actuated devices (CAD) in some fixed-wing aircraft by the vendor, Martin Baker. The service said it used “validated radiography procedures” to scan on-hand inventory to verify replacement CAD parts were made correctly before starting to send them out to the fleet. The service said the CADs specifically “initiate a series of automatic functions when aircrew pull the ejection handle to safely egress the aircraft and deploy the aircrews’ parachute.” Navy Air Systems Command (NAVAIR) spokesperson Marcia Hart told Defense Daily that the CAD issue was discovered after removal of an injection sea during routine maintenance. The Navy emphasized that only CAD-equipped aircraft within a “limited range of lot numbers” are affected, but this includes the Boeing [BA] F/A-18B/C/D Hornets and F/A-18E/F Super Hornets, EA-18G Growlers, T-45C Goshawks and Northrop Grumman [NOC] F-5 Tiger II trainers.
