Skyhawk vs. Mooney
I was simply wondering if someone could break down the cost difference
of a 172 and M20. Obviously maintenance on a mooney is going to be a little more and the fuel burn is a gallon or so more, so just some thoughts. |

Obviously maintenance on a mooney is going to be a little more and the fuel burn is a gallon or so more, so just some thoughts. Depends on the Mooney. The M20C has about the same full burn as the Skyhawk (8 gal/hr) but does 150 knots vs. the 172's 100ish knots on that fuel. The M20C also sells for about the same price as the 172. However, a M20C is more maintenance than a 172 and requires an A&P that has more specialized knowledge (all A&Ps know how to work on 172s). Also, insurance could be a big difference. The retractable gear will cost you somewhere between $500 to $2000 per year additional depending on the amount of retract time you have. A couple things to check for in a Mooney... 1) Fuel leaks. Mooneys have no fuel tanks, just sealant on the skin to hold fuel in. Every so many years an owner is well advised to go into the tanks and freshen up the sealent. If you are very rich you may pay someone to totally replace the sealant but that is rarely required. 2) Gear actuator. If the Mooney you are looking at has electric gear make sure the AD has been complied with the check the actuator gear. Technically this is a recurrent AD but if the gears aren't chewed up the first time you look, chances are you didn't get the bad lot and will be good forever. 3) Also, if you fly more than 100 hours a year, you will end up having to do an annual every 100 hours. There is an AD that requires all flight control connections and gear sections to be lubed every 100 hours. There is really no way to do this without totally taking the plane apart (figure 10 hours of your time to remove all the panels unless you have a one-piece belly). By the time you pull all the panels off to lube you've basically set up for an annual anyway. Some A&Ps consider this unnecessary and will sign off the 100hr ADs for 3 hours of labor, but there is no way they are actually meeting the strict requirements of the AD in that time. However, know that there are many Mooney owners out there that haven't properly lubed their plane in 10 years and are flying all the time so you aren't going to fall from the sky. -Robert, CFII (and Mooney instructor) |

The A owner absoluetely loves his A. There is nothing wrong with an A, in of it self, but you need to keep it hangared. Greg |

The only ones on my list a inspection of fuel injector fuel lines required by AD 2002-26-01 inspection of Bendix magneto ignition switch required by AD 76-07-12 inspection of Bendix magneto impulse coupling required by AD 96-12-07 Dave |

If that's true that is a deal breaker. Take the plane apart every 100 hours for a lube job? Pathetic. |

You probably have less panels to pull but most high performance singles require lube and landing gear inspection every 100 hours one AD or another. -Robert |

You said you may as well schedule the annual for every 100 hours because of all the labor required to accomplish this. That's pathetic and an absolute deal breaker. |
