This is the story of owning and operating a 1993 Beech Bonanza A36 in the UK and some of its adventures and flights. I have owned this plane for over six years now.
I picked up the plane with its new engine in it today.
The guys who fitted the engine showed me some of the parts and despite me thinking it was a waste of time and money replacing the engine they found plenty of faults including
Completely worn out exhaust. There were bits broken off the bafflers in jammed in the tail pipe.
Several holed pipes that fed air into the cockpit and engine.
Several rusted up pipes fittings.
The new engine flies super smooth and has balanced injectors and an uprated alternator on it. There is a book with it where TCM go to lengths to show you how they balance the injectors to make it run msooth. It certainly seems to.
For reference I have to fly it as 2550rpm (Max rpm in this model of A36) and and 25 inches of manifold pressure for the first couple of hours. At that speed at 4000ft with 19 degrees outside air temp I was getting a TAS of 184 knots. Much faster than the book and also faster than the old engine. I wouldnt normally fly at those power settings but you have to during the first couple of hours.
Here are some photos:
Speedy new engine
Knackered Exhaust with baffles almost totally destroyed inside. I hope none of the bits dropped on people as they flew out the end of the exhaust!
and look the can almost melted. They said it was because there was nothing much left inside so it got too hot. The engineers said that was simply down to age of the part rather than any particularly bad running.
We are in the process of fitting a new engine to G-FOZZ because the old one had done about 1650 hours and was 19 years old. It was the original engine and we believed that it was time for a replacement for various reasons.
The plane is at Multiflight in Leeds who were as cost effective as all the other quotes but were a main agent who have supplied parts previously. They were also a 15 minute flight away from Blackpool.
The cost of the engine is £33500 including VAT and a further £7000 including VAT for fitting and parts. We have chosen to buy a factory new engine off the production line but it was possible to purchase a factory overhauled one for £3000 less and a also the option of overhauling our own with significant downtime for a further £3000 less as long as it didn't require any unexpected parts over the standard overhaul. We decided to go the factory new route for the extra cost.
The down time will have been about 10 days in total hopefully.
