At least 10 ambulances and three fire engines were waiting for the stricken plane, the emergency department said.
Dan Andrei, the airline's vice president, said, "the plane came down on the side wheels; it braked sharply and at a low speed it came on its front belly, while the front landing gear remained stuck."
The company said the two Moldovan pilots - Iurie Oleacov, 37, and Leonid Babischi, 47
-were highly experienced.
The Saab 2000 aircraft was carrying 47 passengers and four crew members on its flight from the Moldovan capital, Chisinau, to Timisoara, airport spokeswoman Carmen Stoica said.
Timisoara ambulance chief Iancu Leonida said no one was hurt, but people were very frightened.
"There are no injured people, although some might have minor scratches, but they are very scared and traumatized," he said. "They are being given medical care."
Realitatea TV broadcast footage of passengers hugging and kissing people who had come to meet them at the airport. One unidentified female passenger with gray hair and tears in her eyes told the TV the passengers did not know about the landing gear and had thought there was a problem with ice and fog.
The airport was closed for 2 1/2 hours Saturday morning after the incident.
A Romanian Transportation Ministry team arrived in Timisoara to investigate the incident.
