A civilian helicopter that went missing after it left Bulacan yesterday for General Nakar town in Quezon province was found by the Air Force on Tuesday afternoon.

The aircraft, owned by MacroAsia, an aviation and transport services provider, took off from from a compound of the Metropolitan Waterworks and Sewerage System (MWSS) in Norzagaray, Bulacan.

It was bound for General Nakar to pick up a team involved in the recently concluded search, rescue and retrieval operations for workers who got trapped in the Sumag River Tunnel in General Nakar at the height of flooding last August 13.

The chopper was declared missing when it failed to reach its destination in Sumag River.

Authorities found the wreckage of the aircraft in Barangay Umiray in General Nakar, Air Force Spokesman Col. Araus Robert Musico said.

He added that the search and rescue team was not able to land in the area because of thick vegetation.

The team saw the tail boom of the aircraft. Musico said, although they have yet to confirm that the wreckage belongs to the crashed helicopter, the tail boom found in the area matches the missing aircraft.

The official also said the local government has been informed of the incident so they can send people to the area.

The fate of the aircraft's pilot and co-pilot has yet to be determined.

Musico said there was no indication that the aircraft was burned.

Six workers got trapped after a tunnel collapsed in Sumag River due to monsoon rains on August 13.
