Jeff Wilson sent us the photo above taken September 19 of an MD-87 dropping on the Tenderfoot 2 Fire east of Dillon, Colorado. Thanks Jeff!
The fire was reported above Dillon Reservoir at 5 p.m. MDT September 18 and burned 21 acres on a steep slope before firefighters contained it, aided by two large air tankers and two helicopters dropping water and retardant September 18 and 19.
Resources working on the fire included Lake Dillon Fire-Rescue crews, one U.S. Forest Service engine crew, a 20-person hand crew from Rifle, and a 22-person initial-attack hand crew from the Upper Colorado River Fire Management Unit.
The fire was caused by sparks from a blown insulator cap on a power line that subsequently ignited nearby grasses.

Helicopter photographer Kevin Takumi shows the perfect technique for filming an air tanker drop. He zooms in close at first on Air Tanker 910, a DC-10, then at the completion of the drop zooms out so you can see where the retardant lands.
In these videos by Terry Nelsen, Erickson’s MD-87 air tankers are seen dropping water on the Rankin Fire in Wind Cave National Park in South Dakota September 13, 2017. Both Tankers 101 and 103 were used on the fires in the area.
One of the firefighters told us that after the Rankin Fire had been burning for a while an MD-87 en route to drop water on the fire in the park was diverted to a new fire just starting, the Beaver Fire between Wind Cave NP and Pringle, South Dakota
Wind Cave NP has a policy that the Park Superintendent can on a case by case basis decide if retardant will be banned on individual wildfires. In the case of the Rankin Fire, he decided he did not want retardant used, so the air tankers were using plain water.
Fire engines are allowed to drive off the road to suppress fires in Wind Cave National Park but in some cases retardant is banned.
It is specified in their Supplemental Type Certificate.
There have been several questions and comments from the readers on this website about why Erickson Aero Tanker’s MD-87 air tankers drop retardant with the landing gear down. The most commonly accepted explanation was to reduce airspeed, especially when making a downhill drop. This was why some older air tankers, like the DC-7 according to “Johnny”, kept the gear down.
But Erickson’s MD-87’s are required by the FAA to lower the gear while dropping — in fact it is specified in their Supplemental Type Certificate (STC) issued by the FAA. The reason is the prevention of stalling.
Earlier this year Ericson petitioned the FAA for an exemption from this requirement, and requested a “Flaps 40/Landing Gear Up” configuration while dropping, but on June 28, 2017 that exemption was denied.
Below is an excerpt from the decision which was signed by Michael Kaszycki of the FAA’s Aircraft Certification Service:
I deny Erickson Aero Tanker, LLC’s, petition for an exemption from 14 CFR 25.201(b)(1), that would have allowed aerial firefighting retardant drops in a configuration that does not fully meet the stall characteristics requirements on the modified DC-9-87 (MD-87) airplanes.
The Los Angeles Fire Department is not saying much about an NTSB investigation into an accident that involved their brand new firefighting helicopter, Fire 4, an AW139 that they just put into service one or two months ago. On September 2 Fire 4 was making water drops on the La Tuna Fire in Los Angeles and struck a tree, according to a preliminary accident report by the FAA.
At least one person told NBC 4 in Los Angeles that while monitoring fire traffic on a scanner he heard the pilot say he hit something and put out a Mayday call. The pilot made a successful emergency landing at the Verdugo Hills High School football field.

Heliweb has photos that appear to show small tree branches embedded in the damaged areas of the fuselage while the aircraft was parked on the football field. The helicopter apparently received substantial damage to the tail boom, stabilizers, and left side sponson/wheel housing. The left side stabilizer is missing in the photos.
Incident Commander Todd Hoover provided information about the Beaver Fire east of Pringle, South Dakota, September 14, 2017. We asked him about how aircraft were used, and we also have video and still photos of firefighters, air tankers, and helicopters.
The fire has burned approximately 400 acres between Wind Cave National Park and Pringle, South Dakota. On Friday, September 15, it was slowed by rain in the area.
