Natural and Environmental Resources (DNER) Secretary Waldemar Quiles Pérez said Wednesday that the agency’s Cessna Caravan 208D aircraft has made some 35 flights from March to August, demonstrating the need for a modern and flexible air unit.


“In February, the installation of a new engine was completed on our Cessna Caravan, representing a $365,000 investment. The aircraft has been modified to carry more cargo,” Quiles said in a written statement. “Since entering service in March, over 35 flights have been conducted (through the end of August), demonstrating the need for a reliable aircraft and a top-notch team of professionals who keep it flying. This is a unique platform that allows us to be agile at all times.”


The aircraft, built in 2004, can fly up to a maximum altitude of 25,000 feet; however, regular DNER operations are limited to about 5,000 to 7,000 feet.


When it was acquired 21 years ago, the plane cost $1.4 million. Today, its value is estimated at just over $1.8 million. Upgrades to the aircraft will allow it to operate until at least 2035, the DNER chief said.


“Our aircraft’s primary flights are to the Mona Island Nature Reserve every week to transport staff, including biologists, as well as supplies and equipment, among other things,” Quiles said. “It’s important to remember that Mona Island has an unpaved airstrip, which is why this particular aircraft is so crucial. This mission is vital because it allows us to maintain the facilities on Mona.”


The secretary noted that he is evaluating possible improvements to the airstrip on Mona Island.


“Additionally, the aircraft is used to monitor for emergencies and mobilize personnel in case of an emergency, such as when someone gets lost in the Mona Island reserve,” he added.


The aircraft is based at the DNER hangar at the Fernando Ribas Dominicci Regional Airport on Isla Grande. The facility is in the final stages of a comprehensive renovation following damage caused by Hurricane Maria in September 2017.
