Authorities are investigating a ground collision at Ninoy Aquino International Airport (NAIA) involving a Saudia aircraft and a parked Philippine Airlines (PAL) plane, the airport operator New NAIA Infra Corp. (NNIC) says. Multiple reports state that the incident occurred late Monday to late Tuesday, when Saudia Flight SV871 was taxiing for departure. NNIC reports that at about 11:38 p.m., the left wingtip of the taxiing Saudia aircraft struck the tail section of a parked PAL Airbus A320 at low speed. NNIC says no injuries were reported. It adds that passengers aboard the Saudia flight safely disembarked, and PAL says no passengers or crew were on board its aircraft at the time of the collision. Reports also note that the subsequent Saudia flight was cancelled. NNIC says airport operations were not significantly affected. The investigation is ongoing, and authorities are expected to determine the circumstances surrounding the collision, including aircraft positioning and handling during taxiing.
