The Finnish air force has released images showing the effects of volcanic dust ingestion from inside the engines of a Boeing F-18 Hornet fighter, while it prepares to make inspections on several additional aircraft.
Five of the air force’s Hornets were involved in a training exercise on the morning of 15 April, just hours before the imposition of airspace restrictions due to the ash cloud spreading from a major volcanic eruption in Iceland.
One aircraft’s engines have been inspected so far using a boroscope, with melted ash clearly visible on its inside surface. The air force decided to release the images to show the potentially damaging effects of current flight activities, says chief information officer Joni Malkamäki.
“The images show that short-term flying can cause substantial damage to an aircraft engine,” the air force says. Continued operation could lead to overheating and potentially pose a threat to the aircraft and its pilot, it adds.
Checks will soon be made on the other four aircraft involved, and some engines will be removed to help Finnish company Patria – which provides in-service support for the nation’s F-18 fleet – to assess the extent of any damage caused. Its fleet comprises 55 single-seat F-18Cs and seven two-seat trainers, with each powered by two General Electric F404-402 engines.
Finland halted air force training flights yesterday, but the air force will continue to perform operational sorties as required, such as air policing missions and national security tasks.
One of its BAE Systems Hawk jet trainers also flew from Kauhava air base twice yesterday carrying an air sampling pod which collected dust from the atmosphere at various altitudes.
The air force is sharing the gathered information with the Finnish civil aviation authorities, and says it will stage more such flights as requested.
God hiccups and all of man’s vaunted high technology falls into the scrap heap.
That is a very light looking F-18. Didn’t know ash could make it lose an engine.
Could this be developed into some kind of weapon to prevent air assaults?

No real surprise - I expect this would be like having the engine ingest ground glass.
Decades ago, the US Army Chemical Corps investigated chemical smoke that would inhibit combustion in engines. I don’t know if anything ever came of it.
That’s a BAE Hawk trainer.
Thats an F-18? I thought the engines were at the rear.
Is that the BAE air-sampling trainer?
Wrong picture.

“”September 2009 saw City Of Edinburgh take on a fresh significance when the environmental campaign group 10:10 bought the fuselage of the plane and had it converted into thousands of 10:10 tags. The tags, made in the shape of the campaign’s logo, are worn as necklaces or bracelets and are used to raise funds and awareness of 10:10’s work, primarily to persuade individuals, organizations and businesses to reduce their carbon emissions by 10% in 2010. On 7 April 2010, the process was documented in a news feature shown on BBC Scotland.[11]””
It’s a picture of the BAE Systems Hawk jet trainer also mentioned in the story. All the pictures are from Flightglobal.com.
I saw that. Mega Barf Alert needed.
It probably is.
Do you think I read these threads!?
