An Airlines of PNG (Papua New Guinea) de Havilland Dash 8-100, registration P2-MCT performing a charter flight from Komo to Port Moresby (Papua New Guinea) with 23 passengers and 3 crew, was cleared enroute to FL190 in accordance with their flight plan and was on that flight level about 22nm east of Kerema (Papua New Guinea).
The Dash 8 was tracking outbound from Kerema waypoint on a near reciprocal heading to P2-TAH, when the short term collision alert at the controller's desk and the TCAS systems on board of each aircraft activated. P2-MCT received a resolution advisory to climb, P2-TAH a resolution advisory to descend, both crews complied with the resolution advisory, P2-TAH at the same time initiated a right hand turn, the crew of P2-MCT initiated a turn to the left, the controller while not interfering with possible TCAS resolution instructions instructed both aircraft to turn right. Due to the left turn by P2-MCT the aircraft were turning towards each other, as both followed their climb and descend instructions the conflict was cleared.
P2-MCT had climbed to FL200 while the resolution advisory was active, after being clear of conflict the crew requested and was cleared to return to FL190 and continued to Port Moresby for a safe landing.
P2-TAH, after being clear of conflict, established with ATC that they had been cleared to climb to FL180 only, completed the descent to FL180 and continued to Mount Hagen for a safe landing.
Papua New Guinea's Accident Investigation Commission (AIC) is investigating the occurrence rated a serious incident.
