THE Land Transport Authority will go beyond just inspecting buses to determine the causes of fire.
It has confirmed it will go behind the scenes targeting those involved in the maintenance of buses.
This means drivers, electricians, mechanics and those who work in the garages will also be investigated for what the authority says can be "the reason behind the bus fires".
Authority CEO Naisa Tuinaceva said they were looking into all the previous bus fire incidents.
"Right now we are looking into other aspects. When we are grilling all these fires, we are asking a lot of questions. We want to know the cause of fires," Mr Tuinaceva said.
"We are looking for solutions — short term and long term. We are also looking into the players in the bus industry. You have the mechanics, drivers, operators, electricians. All these people play a vital role in ensuring the fitness of the bus."
He said those who drove and serviced the buses must know their job well.
"Fire just does not happen. It's caused by something. So it's the driver or the mechanic who will be able to pick this up and do something about it. If they sit back and don't know what they are supposed to do, it will be a very big problem."
Allegations of sabotage of e-ticketing consoles also surfaced, which Mr Tuinaceva said the authority was aware of.
"From the beginning of the e-ticketing talk, we are aware of those who resist, we are aware of some bus drivers and operators that refuse e-ticketing because they don't want to be transparent with the money being paid as bus fare."
Nasese Buses Limited director Jack Kumar blames the e-ticketing system as the cause of fires.
But back-end solution provider Foneology said the machines were installed in about 900 buses around the country and questioned why those buses did not catch fire as well.
Director James Trusler said following bus fires, they did a joint inspection and found some burnt wires under the buses that had nothing to do with the e-ticketing system. Mr Tuinaceva said they were also investigating these claims.
