Narrative:
ATI flight BM392 was a scheduled service from Roma-Fiumicino (FCO) to Foggia (FOG). The flight was cleared for takeoff from runway 16 and takeoff was accomplished at 21:56. Immediately after takeoff the crew contacted the Rome Departure controller. The controller confirmed the en route clearance via Pratica, Latina and Teano. He then instructed the flight crew to contact Pratica di Mare. The crew was not able to contact the air traffic controller at Pratica di Mare. At 22:00 the flight contacted Rome Departure again. They reported leaving FL65 for FL110 and noted their problems of contacting Pratica. They were then instructed to call Rome-Control (Terminal Sector South). At 22:04 flight 392 contacted the Terminal Sector South controller and reported at FL100, estimating Latina at 22:10.
At 22:05 the flight was cleared to climb to FL150, following the specific request of the pilot. The F-27 was also cleared for a direct route to Teano, skipping Latina.
Three minutes later the pilot reported passing FL135 and the crew were instructed to switch frequencies to Teano. Nothing more was heard from the flight. By then the flight entered an area of poor weather with local thunderstorm activity. The aircraft had almost reached FL150 when it suddenly lost 1200 ft of altitude and the airspeed dropped 30 knots. This developed into phugoid oscillations from which the pilots were not able to recover. The airplane entered a descent and struck the ground at 340 knots at an angle of 20 degrees.
