An investigation into last November’s fatal helicopter crash in Glasgow, Scotland has found that both the aircraft’s engines “flamed out” suddenly, causing it to lose power and fall “at a high rate of descent”.
The UK’s Air Accident Investigation Board (AAIB) said it was still unclear why both the engines had cut out, despite weeks of exhaustive examination of the Eurocopter EC135 T2 wreckage.
There was no evidence of any damage or malfunction of the fuel supply and transfer pumps, nor was there any evidence of foreign bodies or blockages, while the engine fuel control units were “found to be serviceable in all respects”.
“There was no evidence of foreign object damage or intake or exhaust blockage in either engine. Also, there were no signs of bearing or lubrication system failure, and the oil system chip detectors were clean and free from metallic particles.”
Ten people were killed when the Eurocopter crashed down onto the Clutha bar in central Glasgow.
