Last week we received a video of an engine failing on an MD87 air tanker as it was taking off July 30, 2018 at Coeur D’Alene Airport in Idaho en route to drop retardant on a wildfire. The fact that the engine failed that day was well known, especially since hot debris falling from the aircraft started seven fires within a five-mile radius of the airport. One of the firefighters was injured while suppressing the fires.
This week another video has surfaced about an engine failure on an MD87 that received little or no publicity. Tanker 107 was just beginning its takeoff as Robert Barnes shot the video near his hangar at Chico Metropolitan Airport on the first day of the Camp Fire which burned into Paradise, California, November 8, 2018. The smoke in the background is from the Camp Fire.
Mr. Barnes said that after the incident a City of Chico truck hauled away large chunks of metal that looked to him like they came from a jet engine. He heard the Tower caution other air tankers to land long on Runway 31 due to F.O.D on the approach end.
On July 30, 2018 an engine on an MD87 air tanker failed while taking off at Coeur D’Alene Airport in Idaho en route to drop retardant on a wildfire. The reports at the time was that it failed after takeoff, but in this video that just came to light filmed by Harold Komm, Jr. it appears that the incident occurred during takeoff while the aircraft was approximately half or two-thirds of the way down the runway. At 0:52 in the video below, smoke or debris can be seen in the vicinity of the tail of the aircraft. Then the engine noise decreases as the takeoff continued. When it finally became airborne dust is kicked up at the end of the runway.
The flight crew deserves high praise for getting the plane into the air and then landing safely. An engine failure at that point is one of the worst times for it to happen.
The aircraft was Air Tanker 101, an MD87 operated by Erickson Aero Air. Mr. Komm said that after takeoff the plane flew out to the designated retardant jettison area about seven miles northeast of the airport so it would not have to land with a full load of retardant.
Seven fires were discovered after the incident within a five-mile radius of the airport. One of the firefighters was injured while suppressing the fires.
Mr. Komm said he just recently found a report of the incident on Fire Aviation and offered to allow us to publish his video. We had to edit the audio to remove some unwanted background noise unrelated to the aircraft, but other than that and adding titles at the beginning and the end we didn’t change the video. He told us, “I had talked to Erickson Aero Air HQ in Oregon to make sure it was ok for me to distribute and the only thing was that I had to forward a copy of the video to the lead mechanic. I got some cool swag from Erickson Aero Air for being in the right place and time doing the video.”

An engine malfunctioned on an air tanker operated by Erickson Aero Air July 30 after taking off from the Coeur d’Alene Airport in Idaho. A person we talked with at the airport said they heard a very loud “boom” as the engine failed, and said the aircraft was an MD-87 air tanker. Mike Ferris, a spokesperson for the U.S. Forest Service, the agency that contracts for the large and very large air tankers used by the federal government, confirmed Wednesday evening that “an Erickson Aero Tanker MD-87 did have an engine upset shortly after takeoff from the Coeur d’Alene Airport on Monday at approx. 1430 PDT”. He said the aircraft landed safely after the incident.
The Coeur d’Alene Post Falls Press reported that unofficial sources have told them that hot debris from an air tanker engine started multiple fires after the pieces fell to the ground north of the airport. They also wrote that the runway was closed while “unspecified debris” was removed. The newspaper was not able to find any government officials who would comment about the cause of the fires, saying it was under investigation.
Kootenai County Government reported on their Facebook page that “several small fires resulted from an aircraft incident” at the airport.
(UPDATE at 6:16 a.m. PDT August 2, 2018: Late yesterday Jim Lyon, Deputy Fire Marshal/Public Information Officer with Northern Lakes Fire District, issued a statement confirming that a jet-powered air tanker under contract to the U.S. Forest Service, at approximately 2:30 p.m. “had mechanical problems on take-off and was able to make an immediate circle route to return to base safely. In so doing, it appears the plane was discharging some sort of material as a result of the mechanical problem, starting several fires throughout the area approximately a five mile radius of the airport.” Marshal Lyon said “up to eight fires” started by the incident were under control by the evening of July 30th.)
Below is an excerpt from a July 31 article in the Spokesman Review about the incident:
Jim Lyons, spokesman for Northern Lakes Fire District, said crews battled about seven fires, though none grew to the size of a major wildfire. The first blazes started about 2 p.m. and spread from there.
Shoshana Cooper, spokeswoman for the U.S. Forest Service in North Idaho, said the fires burned to the northwest, south and east of the airport near U.S. Highway 95. She said they burned mostly grass and brush and were not affecting structures. As of 3:30 p.m., no structures had been lost.
Multiple aircraft were sent in to drop retardant on the blazes, but firefighters weren’t sure early Monday afternoon how large the fires had grown.
KXLY reported that a firefighter was injured while working on one of the fires near the airport:
A Kootenai County Fire and Rescue firefighter was injured Monday evening when he was struck by a vehicle that was backing up on Dodd Road by Strayhorn while responding to fires burning near the Coeur d’Alene Airport. He was evaluated at the scene. His injuries were not life threatening, but he was transported to Kootenai Health as a precaution.
The airport resumed normal operation at about 6:30 p.m. Monday.
We were not able to find a SAFECOM report about the incident, and very few people are willing to talk about it. Our calls to personnel at Erickson Aero Air late in the afternoon August 1 either were not returned right away or the employees we talked with were not able to comment.
KMPH reports that the pieces of metal that fell into a Fresno neighborhood Sunday afternoon September 13, breaking a car window, came from an engine that failed on an air tanker, reportedly an Erickson MD-87. Below is an excerpt from their article:
…The plane had departed the Fresno Airport around 3:30 p.m. Sunday when, according to the Federal Aviation Administration and Fresno Firefighters, the pilot reported a left engine failure.
Shortly after, families in a neighborhood near Ashlan and Highway 168 said they heard a boom and saw smoke coming from the plane.
In the process, pieces of the plane’s engine fell into a neighborhood. At least one piece shattered a windshield. Others landed on the streets.
The plane returned to the airport moments later…

We don’t know what caused the engine to fail, and it might not be related, but here is a link to a story we ran in June of 2014 about all three of Erickson’s MD-87s being recalled“ due to intermittent engine surges when dropping [retardant at] high coverage levels”.
All three of Erickson Aero Tanker’s MD-87s have been “recalled” — pulled out of service “due to intermittent engine surges when dropping [retardant at] high coverage levels”. John Kent Hamilton, the Aviation Safety Manager for the U.S. Forest Service Rocky Mountain Region, said the company believes they have a fix for the problem.
Erickson has developed and flight tested a new spade profile that has proved to eliminate this problem by keeping the fluid column much more vertical. They are in the final engineering approval stages and should be able to install with full approval early next week.
Since we ran a photo on January 6 of an MD-87 dropping water in an early test of the retardant system, there have questions raised on our site about retardant being ingested into the engines. That possibility gained further traction on June 9 with a photo of a parked MD-87 with what appeared to be retardant residue above the wing in front of an engine.
When we asked Kevin McCullough, the President of Erickson Aero Tanker, on June 9 if there were any problems with the MD-87s ingesting retardant into the engines, he said there were none.
A few days after the MD-87s began dropping retardant on fires, a retardant leak inside the aircraft required that they be returned to their home base for repairs.
The last time we can remember an air tanker model being recalled was February 8, 2012 when the Federal Aviation Administration issued an Emergency Airworthiness Directive that required inspections of P2V aircraft after a 24-inch crack was found in a wing spar and skin on one of Neptune Aviation’s P2V-7 air tankers. This grounded the entire fleet of federal air tankers until all 11 of them were cleared the next day. Today we have a mix of five aircraft models, all with different retardant systems, reducing the chance that all of them will be shut down at the same time due to a defect.
An S-2 air tanker working on the Clover fire southwest of Redding, California experienced a problem that caused the pilot to have to shut down one of the two engines. It occurred while the aircraft was returning to Chico to reload with retardant. The pilot landed the aircraft safely at Chico according to the Willits News.
Last month Tanker 910, a DC-10, lost their #2 engine just after making a drop on the Beaver Creek Fire in Idaho. They also landed safely, but at Pocotello, Idaho, their reload base.
DC-10 photos on the Morgan Fire
Claycord has three excellent photos of one of the DC-10s (or both of them?) dropping on Mt. Diablo during the Morgan Fire 18 miles east of Berkeley, California. When you visit the site, click on the photos to see larger versions. Both of the DC-10s responded to the fire but soon thereafter were diverted to the Clover Fire near Redding, California which was threatening numerous structures.
It’s just a guess, but what you see in this photo of Tanker 910 over the Beaver Fire in Idaho may be evidence of what led to the replacement of the number two engine last week. The image is a screen grab from the video below which has many excellent still images from the Beaver Creek Fire.
Tanker 910, a DC-10 Very Large Air Tanker, experienced an engine failure coming off of a drop on the Beaver Creek Fire in Idaho on Thursday, August 15. The pilots flew the tanker back to their reload base at Pocotello, Idaho, making a non-emergency landing, said Rick Hatton, CEO of 10 Tanker Air Carrier. The engine, the number two engine which is in the tail, is being replaced and the aircraft should be back in service today or Monday.
Losing an engine is not unheard of, especially in the P2Vs air tankers which have 16 18-cylinder radial engines with many moving parts. For example in 2012 there were two engine failures in a two day period. One occurred in a P2V just after takeoff from Rapid City. Tanker 43 had to jettison their retardant onto the runway, which required its’ closure, diverting at least one commercial flight to another airport.
10 Tanker’s two DC-10s have both been very busy on fires for the last couple of months. Tanker 911 received a multi-year exclusive use contract on June 7 during the next generation award process. Mr. Hatton told us that on June 14 their other DC-10, Tanker 910, received a 60-day exclusive use contract. We had been told by a spokesperson for the U.S. Forest Service that it was a Call When Needed contract like the one awarded to Evergreen’s 747 on June 14. Mr. Hatton said that at the end of the 60 day period the contract will revert to CWN for Tanker 910. He, of course, is bullish on the capability of the DC-10s, and said:
Any future national fleet composition would be significantly enhanced across all the relevant metrics by having six to nine Next Gen DC-10s on long term exclusive use contracts.
