Air tanker strikes powerline

A single engine air tanker (SEAT) struck a powerline while on final approach for a water drop on a fire in northern Idaho. At the time the pilot was not aware of the strike but after making the drop noticed that there was some damage to the left wing. The accident occurred July 28, 2016.

“…New Approach Brings SEAT Over an Undetected Powerline

The SEAT, based out of McCall, was dispatched to the fire near Kooskia, Idaho at 1529 hours. The line strike occurred on the SEAT’s second load delivered to the fire. The first load was split and applied on two different runs prior to a Lead Plane arriving on scene.

On the second load, the SEAT was a little off of the line set by the Lead Plane and the SEAT Pilot was unsure of exactly where the Lead Plane wanted the drop. This prompted the SEAT Pilot to make a dry run.

At this point, the ATGS, who was circling overhead, instructed the Lead Plane to give the SEAT a target and let him work his own approach. The SEAT came back around in a fairly tight circle which created a different final approach than had previously been used. This new approach of the flight line brought the SEAT over a powerline that had not been identified prior to the strike. The Pilot identified the location of the known powerline across the draw and concentrated his attention on the approach as he was lining up for the drop.

Pilot Informs ATGS He Might Have Hit Something

The angle of the bank caused the nose and the right wing of the plane to create a blind spot, obscuring Power Pole 2 from view. The angle of the sun and the dark color of the powerlines would have made them basically invisible against the backdrop of the terrain. The Pilot was unaware of the strike at the time it occurred with the only indication being a brief sound that was not part of the “normal” sounds experienced in the aircraft. The flight was bumpy due to turbulent air that is normal on hot summer days in canyon country. Following the successful drop, the Pilot informed ATGS that he might have hit something.

Pilot Notices Vortex Generators Missing from Left Wing

The Pilot flew back over the drop area and confirmed that the known powerline was still intact. He did not locate the poles from the line that had been struck. As he was heading back to the dip location, he looked out at his left wing and realized that numerous vortex generators were missing. The vortex generators are glued on the wing and have been known to come off in flight, but normally only under extreme cold or hot weather conditions. Normal flight is not affected by missing vortex generators. Their purpose is to add stability, lift, and performance during dipping and dropping maneuvers. All controls of the aircraft were functioning normally.

At this time, it had not been established that a wire strike had, in fact, occurred. The Pilot was initially going to return to the dip site for another load when the ATGS recommended that the SEAT fly to the Lewiston Air Tanker Base to check for possible damage (56 miles with crash/rescue services). The Pilot informed ATGS that he was returning to base at McCall (83 miles without crash/rescue services).

The wire strike was first confirmed when the Pilot was on the ground in McCall and was able to see the black marks from the wire on the wing. At this time, the Tanker Base Manager in McCall alerted Dispatch to notify personnel on the fire that a wire had been struck and of the potential for hot wires on the ground…”

SEAT base at Hot Springs, SD was busy in July

The Hot Springs Municipal Airport has been a busy place this last month. The single engine air tanker (SEAT plane) based out of the Hot Springs Airport during the summer months has been especially busy. Just in the month of July alone, the Wildland Fire Division crew operating it has flown over eighty fire missions within western South Dakota. Wildland Fire was also quite busy with the Indian Canyon Fire by Edgemont, having four planes flying out of our airport to assist in putting that fire out. We are really glad to have them based here in Hot Springs for immediate the fire protection of our area.

Switching gears from firefighting operations at our airport, we also saw an increase of recreation users this last week during the Oshkosh, WI fly-in. Many planes traveling to Oshkosh for the fly in chose to land in Hot Springs for fuel with some renting hangar space for the night. Many also stopped again on their way home to refuel their planes. Separate of the fly-in, we were lucky enough to see a 7/8 scale P-51 Mustang land here on July 30th. For those familiar with aircraft, you know this was a sight to see.

Fred Celest sent us this photo he took with his cell phone while he was returning from the 16 Mile Fire in eastern Pennsylvania for a load and return. Both planes are operated by New Frontier Aviation out of Fort Benton, Montana. The single engine air tankers are Air Tractor 802s with Garret-14 engines.

We’ve written about T-873 a couple of times before.

Thanks Fred.

Northwest Territories to buy 8 single engine air tankers

The Northwest Territorial government has ordered $26 million worth of single engine air tankers, an acquisition that will add new eight Air Tractor 802 Firebosses to their fleet.

Below is an excerpt from an article at CBC News:

…This is the first time the territorial government has bought new water bombers, which are used to fight fires. It inherited the current fleet of Canadair C-215s, which were introduced in 1969, from the federal government for $1.
The minister of environment and natural resources, Wally Schumann, says it makes more sense to buy the new Air Tractor 802 Fireboss aircraft than to upgrade the old fleet.

“I think the cost of doing that, from everything I’ve seen, would have been four times or five times the cost of purchasing these new Firebosses,” he said.

The government plans to issue a request for proposals this spring for the operation and maintenance of the fleet.

It could have asked contractors to provide a fleet of aircraft as well as operate and maintain them, but Schumann says many northern companies would not have been able to bid on it.

“The biggest benefit of us, the GNWT, owning a fleet of aircraft is the larger chance of Northern aviation companies to participate in the operation of the tanker based fleet,” Schumann said…

Thanks and a tip of the hat go out to Doug.

Interesting aircraft at Burns Air Tanker Base

A Blackhawk and a Homeland Security surveillance aircraft are staged at Burns.

As we reported on January 10, the FBI has been staging equipment at the Single Engine Air Tanker Base at Burns Municipal Airport four miles east of Burns, Oregon. Initially a large truck with numerous antennas showed up that is probably used as an incident command post.

The airport is 21 air miles north of the headquarters of the Malheur National Wildlife Refuge where armed domestic terrorists broke into and seized the facilities at the site.

In the last few days additional equipment arriving at the tanker base included about half a dozen armored vehicles, a Blackhawk helicopter, and a Beechcraft Super King Air 350 surveillance aircraft (N50056) with very obvious external accoutrements, sensors, and communications gear.

The King Air, registered to the Department of Homeland Security, has a logo that appears to be “U.S. Customs and Border Protection”. According to FlightAware records it flew in from Boise on January 27 after having been at St. Augustine, Florida on January 25. 

The Bureau of Land Management operates the SEAT base independently of the city-owned airport which remains open. The base, which cannot handle air tankers larger than a SEAT, has one pit for loading aircraft and parking for three.

The FBI’s Blackhawks are rarely seen. Below is an excerpt from Wikipedia about aircraft operated by the agency’s Hostage Rescue Team:

The HRT’s Tactical Aviation Unit is staffed by FBI special agents. The Tactical Helicopter Unit, a sub-unit of the Tactical Aviation Unit, contains a variety of specially modified helicopters. These helicopters include military converted Sikorsky UH-60 Black Hawk tactical transport helicopters and tactically enhanced Bell 412 and Bell 407 helicopters. The HRT’s tactical aviators are required to fly daily.

Thanks and a tip of the hat go out to Matt.

FBI stages at Burns Air Tanker Base

The Federal Bureau of Investigation is staging equipment at the Air Tanker Base at Burns Municipal Airport four miles east of Burns, Oregon. The Oregonian reported that FBI personnel were blocking the entrance to the Bureau of Land Management’s Single Engine Air Tanker Base and that “… a large vehicle sat equipped with FBI signage, numerous antennae, a satellite dish and other gear.” Law enforcement officers have been seen at the site for several days.

The airport is 21 air miles north of the Headquarters of the Malheur National Wildlife Refuge where armed domestic terrorists have broken into and seized the facilities at the site.

The BLM operates the base independently of the city-owned airport which remains open. The general aviation airport, with two runways a little less than a mile long, began as a military air base in the 1940s. The SEAT base, which cannot handle air tankers larger than a SEAT, has one pit for loading aircraft and parking for three.

Reuters has photos of the FBI agents at the airport.

Simulator for a fire retardant dispersal system

David Benson of Trotter Controls sent us information about a simulator for their fire retardant dispersal system. The company makes the GENII firegate and controller for Air Tractor AT-802F single engine air tankers. Anyone with a Windows-based computer can download the program to train with the system.

Here’s how they describe the simulator:

This Windows-based simulator allows pilots to operate a virtual Fire Retardant Dispersal System (FRDS) and firegate from a personal computer. This is great training for new SEAT pilots and is just downright FUN. The simulator is a free download.

Whether you already own an FRDS GEN II, or you’re just considering an upgrade to the FRDS GEN II, you should check out the app. You’ll be amazed at how simple operating the world’s premier fire gate truly is.

 

The BLM had two popular air tanker videos in 2015

On Twitter, @BLMOregon described the following Vine video of a Single Engine Air Tanker, like this:
