The DHC-6 Twin Otter plane lost contact 11 minutes after taking off in good weather Friday from Masamba in South Sulawesi province, said Transportation Ministry spokesman Julius Barata. No distress signal was received.
The plane, owned by the private Aviastar Mandiri airline, was headed for Makassar, the provincial capital. It was carrying three crew members and seven passengers, including three children, Barata said.
Four aircraft were deployed to search for the missing plane, said Petrus Budi Prasetyo, commercial general manager for the airline.
Ahmad Munir, head of the airport authority in Makassar, said satellite data showed the aircraft's last known position was about 32 kilometers (20 miles) from Masamba.
Indonesia, a sprawling archipelago nation of about 250 million people, has been plagued by transportation accidents in recent years, including plane and train crashes and ferry sinkings.
It is one of Asia's most rapidly expanding airline markets, but is struggling to obtain qualified pilots, mechanics, air traffic controllers and modern airport technology.
