The good old Turmo IIIC4. A faithful, reliable gas guzzler. Despite its lack of sophistication (or perhaps because of it) I never personally had a failure in 10 years on the Puma. Can't think of any suffered by anyone else, either. The one so-called failure on take off I can recall about 25 years ago might have been a "man/throttle positioning interface" issue.
Had at least one big wood pigeon (it might have been two at the same time) go down an intake, at low level in Germany (PIPS not then fitted). The engine never coughed or burped, everything just carried on working. We landed on to have a look. Lots of partly cooked pieces of pigeon and burned feathers in the exhaust can and a smell of barbeque. Nothing to be seen on the compressor. Engineers said it looks OK, so if it starts and it works OK, take it home for a compressor wash. We did, and there was no damage.
