Murphy Moose or Cessna 185?

Posted on by
Question. 
I’m considering either building a Murphy Moose, or buying a Cessna 185.  I want it for flying in canoes and kayaks to remote locations in North America (last trip was canoeing near the Arctic Ocean).  I’m not yet even a private pilot (but will be by summer).  I want a budget planning estimate of what the operating cost of either of these aircraft are going to cost me, equipped with amphibious floats, for a qualified pilot with low hours.  Can you do that?










Answer. 
Sort of.  I consider the Murphy Moose and the Cessna 185 to be pretty close in operational costs as far as fuel burn, maintenance etc.  A lot will depend on the engine used in the Moose.  Another big difference will be that you will build the Moose and you can do the maintenance if you have the repairman certificate.  The Cessna 185 will need a shop and mechanic to do the repairs.  But the savings you get in maintenance for the Moose will probably be made up in the insurance premiums.  Since it is an experimental aircraft and since it will be on amphibious floats, insurance will be almost impossible or at least very, very expensive.  Not to say the insurance for a low time pilot in a Cessna 185 will be that much lower, it will still be expensive. 
I’d look into calculating the average cost to operate a Cessna 185 or maybe even a 206. Contact me for a free sample cost of ownership Excel spread sheet. 
I’d also contact a few owners and see what they are saying.  I have been told that the Cessna 185 costs about $130 an hour to operate, not counting the floats.  It would be worth your while to do a little research before you make a decision. 
It will also be necessary for you to build up a number of hours as a pilot AND as a seaplane pilot.  The chances for a low time pilot (under 500 total time and 100 seaplane hours) of getting any insurance will be very low. 
That might also make the difference in which aircraft you get.  If you build (or build) the aircraft without having to borrow money, insurance might not be required.

On a side note: Murphy Aircraft feels the Moose is probably closer in operation to a Dehaviland Beaver.   Okay, I have to say, that’s a selling point for the Moose right there. Who hasn’t wanted a Dehaviland Beaver?  I may be a Cessna fan but a round engine aircraft on Amphibs…

Is oil analysis a good idea

This is a good question for not only aircraft owners but ,boat and performance car owners. too.

Question. Is oil analysis a good idea or just a waste of money?
Answer. 
I think it depends on the engine.  Most mechanics would probably agree that a high time engine would benefit from oil analysis.  If you are trying to extend the time between overhauls (TBO),  oil analysis is a must.  Flying your aircraft past TBO can save you a few bucks in the near future but can (but not always) increase the actual cost of the overhaul in the long term.  It could be one of those “pay me now or pay me more later”!  Extended use might damage parts instead of just wearing them down.  

But oil analysis and regular oil changes can help the owner monitor some of the internal conditions of the engine.  Which also means if you start a new engine on the oil analysis program from the very start you can continually monitor the engines wear throughout the years of operation. 

Typically, the average oil change would be sufficient for most owners to check the oil for any contaminants.  The mechanic or owner  who does the oil change should cut the filter, or inspect the oil screen and look for any type of contamination.  If you are looking at an aircraft to buy, and you have the time, an oil analysis would probably offer you finer (no pun intended) details than just the filter or screen test.  In fact, if you find something in the screen or filter it will probably indicate wear or damage that may be significant and might be a indicator that you should do oil analysis.

So in the end, no I do not think it is a waste of money.

Proficiency training Simulator or aircraft?

Posted on by
The following question from a customer asked about doing regular training.  Its important to note that sometimes insurance companies require training in a specific class or category of aircraft.  For example; if you fly a pressurized or cabin class aircraft, you will probably be required to get “factory approved”  initial ground and flight training along with recurrent training after that. Most companies require recurrent every year but there are a few that will go for two or three years between the training. A lot depends on the type of aircraft you are flying.   
That said —- 
Q. Proficiency.  I’m thinking of going to a school such as RTC, Flight Safety etc.  Most of these companies do simulator training.  Am I better off going out with an instructor, doing the FAA Wings kind of thing, or going to a school?  Training in the airplane will give me some dual, my Instrument Proficiency Check (IPC) and my flight review?  Which is a better way to go?

A. That’s a tough one.  From an insurance standpoint, many of the underwriters require training from a factory approved school that specializes in your specific aircraft.  That training is often in a simulator and counts as your IPC, flight review and dual.  That is if it’s from an approved school or training institution. 

I’m a big believer in the FAA Wings programs and flight simulators to keep a pilot proficient.  If the weather is really bad or your checkbook is a little empty, flying with a Flight Simulator program on your home computer can be a great help.  While it might not be logging “real” hours, it can sure help keep your mind in the flying mood.  The Flight Sim program can overlay weather, set up approaches and do almost everything a pilot need s to do to feel comfortable in their aircraft.  Flying to a new destination?  Set up the Flight Sim program to fly into the area, make a few approaches and you’ll feel like you been there before when you get there for the first time.

Whenever possible take advantage of flying the real thing and practice.   Sure I like simulators and software, but I think the real proficiency comes from flying the aircraft.  That’s why we buy an aircraft to begin with.  Hook up with a qualified instructor that you like and go out and have fun and learn at the same time.
