The Civil Aviation Authority of the Philippines (CAAP) on Thursday issued an Ashfall Notice-to-Airmen (Ashtam) warning commercial planes and private-owned small aircraft against volcanic ashfall coming from Mayon Volcano in Albay province in the Bicol Region.
CAAP spokesman Eric Apolonio said they issued the ashtam based on the orange alert of the Philippine Institute of Volcanology and Seismology (Phivolcs), which said the ashfall may affect aircraft visibility.
CAAP, quoting Phivolcs, said all commercial airplanes should exercise extreme caution when passing near Mayon Volcano.
Among the airlines that fly to Bicol particularly to Naga City (Camarines Sur) and Legazpi City (Albay) are Philippine Airlines, Cebu Pacific, Air Asia Zest and small aircraft owned by private companies.
At press time, there were no flight cancelations to Bicol by these airlines.
Meanwhile, aviation authorities at Butuan City airport in Agusan del Sur grounded a PAL Express plane over a fuel leak that was discovered shortly after Flight 2P2967 with more than 100 passengers on board landed.
