While taxiing for take-off in a 172 with the Lycoming 320 H engine I noticed that the oil pressure was progressing towards ZERO. I returned to the ramp and upon further inspection the oil filter was filled with metal. The oil pump had come apart.
I was flying A 76 with the Rolls Royce (ALlison) 250-C30 engine when It started making a loud howling noise. We continued to a landing and while taxing in we got a chip light. Further inspection revealed a bearing was coming apart -not sure which number.
I have had other countless chip lights without resultant engine failures.
I currently operate (fly) an aircraft with a RR 250-C20 and another aircraft with a Pratt and Winney PT6. I haven't had a chip light for quite a while. I hope I didn't jinx myself!

Interesting thread - certainly shows that after the engine installation development bugs are sorted, there is still much that can and does go wrong.
Any new project is a collection of faults waiting to happen. The job of the engineering team is to find them before the customer does.

S300
Magnetos packed up - both did mag drop ok ( about 90 a side ) after 5 mins flying ac started missfiring - yawing 30 degrees left and right a couple of times. Run on landing in field, with engine running not enough power to hover.
S300
Lifted out of a clearing in a wood to 100 ft, transition into forward flight, clear wood. Engine miss fires again yaw left and right by 30 degrees. Enough power to fly but with rod of about 200fpm. Run on landing about 600m away.
All bottom plugs had lead fouling - after 1 hour of teaching ex 26. Student was most impressed knows what to do after he said very calmly "you have control"

Brand new EC130,
Belly panel screw chaffed into wiring loom.....115kts @1000ft...Floats go bang which I cant see.Due to large "Bang" slam collective down and get rather large nose down attitude (Floats and Auto) Christmas tree on warning panel and funny gongs going off in Headset.Engine has gone to ground Idle and a passenger says "your floats are out" I think I replyed thats the least of my
worries. Full auto onto ground and still have stretch marks on my butt from the seat cushion.
Screw had taken out both Fadecs and Ebcau.
So much for new technology

H269 made a clattering noise for about 2 seconds, then totally seized up and went from 2300rpm to zero immediately. Helicopter yawed violently.
Apparently a valve had come loose and lodged in the cylinder causing an immediate stop. Engine and underwear had to be replaced.

The last engine problem I had, the "POWER" light on the faulty engine flashed several times very briefly followed by the associated engine running down to ground idle. Engine runs down, shut it down. AS332L.

One wound down to FI whilst in the hover over Sea state 6.
One exploded when a compressor blade went for a walk.
One surged and blew itself out.
One was taken out by a wave while I was burning and turning on deck at night.
One shut down 'cos I hit the fire button instead of the ignitors (adjacent to each other) on shutting the engine down
All of these happened on twin engined helos during a span of about 3000hrs.
I also have 3000 on singles - and not one of those engines as much as hiccupped

Flying a Robbie, 18 minutes into the flight after picking it up from the maintenance department the oil light, and then the oil pressure gauge reducing. Called Birmingham Radar to say precautionary landing, powered descent, landed and got out to see oil spraying itself all over the engine.
Again a Lycoming 320, oil filter. Yet the maintenance company were rather keen to get there and quickly swap the filter, and upon inspection the oil filter was perfectly intact, the mount was not showing any signs of wear.
Contacted the CAA within the time allowed for an MOR, and then contacted the maintenance company to see if they had filed a report or even said anything, and they answered 'We don't need to bother about that' !!!!!
Flying Robbies can be fun ?
