Investigation

According to the ATC worker in Syamsudin Noor Airport, Captain Herybert had announced the engine failure and had stated his intentions to make an emergency landing. According to the Indonesian Transportation Minister, Haryanto Dhanutirto, the procedure the crew took was correct, and this claim was also correct. Observation on the crash site revealed that the plane's wreckage was heading towards the airport, meaning that the crew did attempt to return to the airport.

Response
In response to the crash, the Governor of South Kalimantan visited the survivor and the injured shortly after hearing the news. Indonesian Minister of Transportation Haryanto Dhanutirto visited the crash site. He, alongside the South Kalimantan Governor, made a condolence statement to the families affected by the crash. Haryanto later added that the local government should make a regulation on industrial location around the airport and its risks.

The insurance company told the media that there would be compensation for each passengers and crew members at Rp 40 million each person. They stated that they would only compensate the surviving passenger's hospital bill, up to a maximum of Rp 10 million. The insurance company, however, would not compensate the victims on the ground.

The General Manager of PT. Barox Utama Jaya, Ranius, stated that he demanded a compensation from the airliner. He stated that his company suffered a Rp 500 million loss due to the crash, specifically a loss of a Fuso truck, an electrical generator, and the shutdown of the factory for three consecutive days. He later added that he would file a lawsuit if the airliner dismissed his demands.

Controversy
The CASA C-212 Aviocar was produced by the Spanish CASA and the Indonesian IPTN. The head of IPTN Bacharuddin Jusuf Habibie claimed that the plane was "tough" in its class. For example, he noted the crash of a CASA C-212 in 1991 in Tihengo Mountain when the plane flew onto a tree and became stuck. Habibie stated that the plane didn't suffer any substantial damage. The same year a Pelita Air Service CASA C-212 crashed into the sea off Lampung. This crash later caused a public debate on the worthiness of the plane.
