JAKARTA, Indonesia — A small passenger plane carrying 10 people disappeared in eastern Indonesia shortly after takeoff on Friday, officials said, in the country’s latest aviation mishap.

The DHC-6 Twin Otter aircraft, operated by Aviastar, a regional carrier, vanished from radar within minutes of taking off at 2:25 p.m. from Masamba, a town in South Sulawesi Province. It was en route to Makassar, the provincial capital, said Petrus Budi, the commercial general manager for the airline.

Mr. Petrus said the last contact the authorities had with the aircraft was 11 minutes after takeoff, when the pilots radioed to controllers in Makassar to advise them that they had reached an altitude of 8,000 feet.

“They said they would check in again about 40 minutes outside of Makassar but never did,” Mr. Petrus said, adding that the flight was supposed to arrive around 3:40 p.m.
