“On Jan. 28, an EH-101 suffered a cracked crankshaft in one of its three engines, which forced it to make an emergency landing at Billund Airport. Following this incident, the Danish fleet was grounded as a security precaution.”
I'm sure the only answer is remove all three piston engines and fit nice new turbines instead.
Must say, though; a very big "Well Done!" to the folk at Westlands who pulled off this amazing sales coup. Those old piston engines must have been sitting in a hangar for donkey's years, just waiting for a gullible customer to come along.
