Third Turkish CN-235 wreck claims all on board

On its final test flight before deployment, a Turkish Navy CN-235 crashed at Ankara-Etimesgut Air Force Base, killing all four aboard.

The military executive plane was one of eight CN-235s being modified for the Turkish Navy, according to the Aviation Safety Network.

Technical malfunction is believed to be the cause. CNN reports that "the pilot lost control of the aircraft at 5,000 metres (17,000 feet) and fell into a steep dive, crashing into a field about 650 kilometres (400 miles) southeast of Ankara."
