An inadvertent release of retardant occurred along a five-mile long path near Lake City, Florida.
(UPDATED at 4:09 p.m. MDT April 19, 2017)
On Tuesday April 18 one of the three large air tankers working on the West Mims Fire on the Georgia/Florida border reported issues while in flight and could not actuate the gate which allows retardant to be released. While returning to the tanker base, one of the tank’s gates had a malfunction, allowing approximately 40 gallons of retardant to be released intermittently along a five mile path, Dan Synder, President of Neptune Aviation told us.
The aircraft that had the problem was Neptune’s Tanker 41, a BAe-146, according to Mike Terry, the Air Operations Branch Director on the fire. On Tuesday it dropped 5,951 gallons. It’s not clear if that included the inadvertent drop. The BAe-146’s can carry up to 3,000 gallons.
The Incident Management Team is advising anyone who was affected by the retardant to call the West Mims Fire Information Line at 904-452-4627.
The West Mims Fire has burned 21,790 acres in Florida and Georgia since it started April 6, 2017. Most of the fire is in the Okefenokee National Wildlife Refuge, John M. Bethea State Forest, and Osceola National Forest.
Thanks and a tip of the hat go out to Willard and Tom.
In this video, Air Tanker 131, a C-130Q, is seen making two drops with water — instead of fire retardant — on the Mud Lake Complex of fires in Big Cypress National Preserve in south Florida. This is an unusual tactic for most large air tankers that normally drop retardant. It was a direct attack on the edge of the fire, rather than being offset as they would usually do with retardant. In the United States, federal policy does not allow retardant to be dropped near water. Many areas in the Mud Lake Complex were near wetlands.
Air tankers that can skim over the surface of a lake, scooping water to refill their tanks, usually drop water instead of retardant. Those aircraft include the Air Tractor Fire Boss, CL-215/415, and the Martin Mars.
Coulson Aviation attached a GoPro camera to the belly of their C-130Q to record the video in May, 2015.
Many of the 1 million acres in Everglades National Park are inaccessible. The swampy terrain is not very conducive to the establishment of an extensive system of roads so park personnel often rely on helicopters to facilitate the accomplishment of a variety of tasks.
The park has a very active aviation program, occasionally using several helicopters in one day.They have contracted for an exclusive use contracted helicopter plus call when needed aircraft since the mid- to late-70s, but in April, 2014 acquired their own ship, a Bell Long Ranger. For now they are using pilots under contract, but are considering, AFMO Jack Weer said, hiring their own pilot. The aviation program is managed by a crew of five.
Approximately 70 to 80 percent of the 450 to 550 hours of aircraft time in the park each year is for research, alligator capture, bird surveys, hydrology, fisheries, vegetation surveys, and python location. About 20 to 30 percent is used for fire management, including recon of wildfires and prescribed fires, aerial ignition, and dropping water with a 108-gallon Bambi Bucket. In 2014, 241 hours were used by call when needed aircraft, and 236 by the NPS-owned ship. Other agencies also use aircraft in the park. Recently the EPA used two float-equipped helicopters for 21 days in order to land at about 120 spots to monitor environmental conditions.
Since the helicopter is generally used in south Florida which has numerous airports, they do not maintain a fuel or service truck like you would see at most fire-related helicopter operations, but they do have a helitack truck and can mobilize a fuel trailer if needed.
In the remote terrain aerial ignition is often used for prescribed fires. Recently fire personnel experimented with a technique for when a burn unit boundary is not a natural fire break. They ignite with the helicopter and after the fire gets going, they use a Single Engine Air Tanker (SEAT) to stop the spread near the intended unit boundary by dropping water. They do not use retardant in the Everglades, due to the fact that much of the park covered with or near water.
We have more information about the wildland fire program at Everglades National Park on our sister site, Wildfire Today.
The Miami-Dade Fire Rescue (MDFR) Air Rescue Bureau has four Bell 412 EPs that are used for fighting wildland fires in south Florida as well as providing regional aero-medical transport, search and rescue, and tactical support to MDFR operations. Jim Hunter, an Aircraft Commander, said about 80 percent of their responses are for medical aids, with the remainder being rescue and firefighting support.
The Bureau operates out of two facilities in south Florida, the Tamiami Executive Airport and the Opa-locka Airport. Maintenance, administration, and training is conducted at the Tamiami facility.
There is always an “alert aircraft” helicopter staffed 24/7 at each location, along with two pilots and two paramedics for each. The other two helicopters are used for backup when an aircraft is down for maintenance. The day we were there, a backup ship was ready to be wheeled out on a dolly to the ramp if needed, and the fourth was undergoing heavy maintenance, which included removing the engines, rotors, and many other components.
During the dry season, January or February through May, the helicopters are equipped with a 350-gallon Simplex belly tank for firefighting, which takes about an hour to install, Mr. Hunter said. The tank has three doors which can be opened independently or all at the same time depending on the need. While the helicopter is hovering, the tank is filled through a snorkle with a 5 gallon per second pump powered by an electric motor.
They also have a 240-gallon Bambi Bucket.
Each aircraft is equipped with the following:
Patient loading systems normally configured allow the transport of two critical-care patients, with the option to reconfigure for up to six patients in Mass Casualty Incidents (MCIs).
An external hoist for helicopter-borne rescues.
An external high-power searchlight, “The Night Sun,” is used for night operations.
MCI Command and Control suitable radio suite.
Night Vision Goggle compatible lighting.
They are also equipped with weather radar, but Mr. Hunter said the pilots prefer to use an iPad connected to the Internet, since it can show troublesome weather at a longer range than their radar.
