The Air Force temporarily grounded nearly 300 trainer aircraft over concerns that ejection seats may not fire correctly, Air Force Times has learned. The service stopped flying 203 T-38 Talons and 76 T-6 Texan IIs that may be affected, Air Force spokesperson Aryn Lockhart confirmed Thursday. That's about 40 percent of the T-38 fleet and 15 percent of the T-6 fleet, including planes at each undergraduate pilot training base and Naval Air Station Pensacola, Fla. The groundings come after the ejection seat manufacturer discovered a potential defect with the explosive cartridges that allow a pilot to escape. The T-38 is a supersonic jet used to prepare pilots to fly fighter and bomber aircraft, and the T-6 is the service’s turboprop plane used to teach basic flight skills. The Navy and Marines also grounded some of their aircraft. Martin-Baker Aircraft Co. Ltd. makes the ejection seats for the trainers, along with the Navy’s F/A-18 Super Hornet, the Air Force’s F-35 Lightning II and a host of other aircraft flown by dozens of military organizations.
