The small aircraft plunged into the shanty town yesterday, exploding on impact and causing a fire that gutted a 2,000 square-metre section of the slum that stands either side of an open sewer.
The crash killed both the pilot, co-pilot, and a third person on board while the other fatalities were residents who died in the resulting inferno.
Five others were reported missing, according to residents, while at least 20 more people were injured.
Emergency crews said they were carefully sifting through the rubble in hopes of finding bodies beneath, although an early morning search turned out negative.
"No more bodies were found this morning," Philippine National Red Cross secretary general Gwendolyn Pang told AFP.
"DNA testing will be done today on those who had been recovered to identify them. They were burnt beyond recognition."
Pang said that the injured sustained serious burns and were being treated at a hospital, including seven children who had been playing near the site where the plane crashed.
Experts from the civil aviation authority said they were trying to recover the burnt-out engine of the crashed plane, as well as other debris that could yield clues as to what caused it to plummet into the slum.
"We want to get the engine block, and we will also check the records of the aircraft and the pilot, including that last conversation with the control tower," said Amado Soliman, of the agency's accident investigation board.
The four-seater planed had just taken off Manila's domestic airport yesterday when it radioed the control tower for permission to return and land, but instead crashed into the shanty town.
It was to have picked up cargo from the nearby island of Mindoro and was believed to have been carrying a full tank of fuel when it went down
