There are still no signs of the missing Cessna 206, almost a week since it went off the radar after taking off from Cauayan airport in Isabela on Tuesday afternoon.
In a statement, the Civil Aviation Authority of the Philippines (CAAP) said no "distress signal" was detected from the Cessna 206 aircraft with tail number RPC1174 with 5 passengers and a pilot.
A distress signal, also known as a distress call, is an internationally recognized means of obtaining help. It is often communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance.
According to CAAP, the aircraft sent no such signal to the Philippines Communication Navigation Surveillance/Air Traffic Management System (CNS/ATM). It added that checking the emergency locator transmitter (ELT) was one of the first steps it made when the small aircraft was declared missing.
Isabela Public Information Office Chief Joshua Hapinat said their rescue team, composed of the army and police personnel contingent, is still verifying reports of debris from the possible aircraft wreckage found on the Iligan-Divilacan road.
The aircraft left the airport at 2:15 PM on January 23 with 6 onboard including the pilot and 5 passengers. They were identified as pilot Captain Eleazar Mark Joven and passengers Tommy Manday, Val Kamatoy, Mark Eiron Siguerra, Xam Siguerra, and Josefa Perla España.
The plane was bound for Maconacon, Isabela but did not arrive.
