Taking off from Gurney, Alotau, the flight took 1 hour and ten minutes and touched down smoothly at Nadzab airport in Lae.
The aircraft spent an hour on the runway while being refuelled before taking to the skies again for Madang.
This is the second time the P2-ATR has visited Lae with the P2-ATR making its inaugural flight into the Morobe Province yesterday.
The P2-ATR will be flying 5 flights to Lae a week. This will increase as the months progress after the arrival of Air PNG's second aircraft in the ATR fleet.
