Aircraft Purchase: The Logbook & Pre-Purchase Inspections

Your about to make your dream aircraft purchase.  The plane has low time on the engine, is reasonably priced, and, according to the seller, has no damage history.  You are overjoyed!  Your dream of making an aircraft purchase is finally coming true.  You prepare your offer for the seller, set up the escrow account, and start all the paperwork.

Two weeks later, the airplane is yours!  You start flying it, though, and the engine starts to have some strange vibrations.  After several flights, it starts to get worse.  You take it to your mechanic to get it looked at and you find out the airplane needs three new cylinders along with some other engine work that is going to total a lot of money.  Plus, your airplane is now going to be in the shop for several weeks.

All that excitement you just had?  It just went out the window.

Could this have been prevented?  Probably so, with a logbook inspection and a pre-purchase inspection.

Aircraft Purchase:  Maintenance Logbooks

Aircraft Purchase: Logbook Inspection

Inspecting a logbook can be very daunting when making an aircraft purchase, especially for older airplanes.  This is, however, one of the most vital steps in making a new aircraft purchase.  You can find out many things from looking at the maintenance logs of an airplane.  First, you can check the compression levels of the engine.  Typically, you want compression levels in the 70’s, with it still being okay in the high 60’s.  Anything below 65 and there could be potential problems.

Second, you can find out if there has been any odd maintenance done pointing to possible unreported damage history.  This is rare, as most aircraft owners are honest and up front when talking about damage history.  But, if there is an entry detailing a prop overhaul after only 50 hours on that prop, you may start to ask some questions.

Third, you can find out how well the airplane has been maintained.  If a lot of maintenance was completed at each annual, even if it was a lot of small things, then the airplane has been maintained by a good mechanic who is very thorough.  This also involves a check of the ADs, Mandatory SBs, SBs, and SLs that have been issued for the airplane.  If all that has been kept up with, it’s a well maintained airplane.

Finally, it gives you a good idea of how much the airplane has been flown.  Sure, the ad online will have the total time and time since overhaul, but you can look at the year by year breakdown of how much the airplane has been flown.  It may have been flown a lot earlier in it’s life, but not quite as much recently.  That’s not necessarily a bad thing, but airplanes like to be flown.

Aircraft Purchase: Pre-Purchase Inspection

Before making an aircraft purchase, it is extremely vital that whenever you are buying an airplane that you get a pre-purchase inspection done on the airplane.  Even better is getting one done by a mechanic who specializes in that type of airplane (eg. Piper Service Center for Pipers, Cirrus Service Centers for Cirrus, Kevin Mead for PA-46s).  A pre-purchase inspection can save you a lot of money in the end.

There is always going to be some kind of maintenance issue with an airplane being purchased, whether it is big or small.  Once a pre-purchase inspection is completed, you can take the findings to the seller and negotiate for a lower price based on those findings, or just have the seller fix the items before the sale is completed.

I would recommend having the seller fix the problems before the sale is completed.  Even though it may take a little longer for the sale to be completed this way, you’ll get to enjoy your airplane right away instead of it being in the shop the next several weeks after you complete the purchase.

There is the circumstance where the  pre-purchase inspection reveals some serious airworthiness issues which would cause the deal to be voided.  Always put this clause in a purchase agreement, giving you, the buyer, an out if there are serious airworthiness issues.

When it comes to making an aircraft purchase, it is not a process to be rushed.  Slow and steady usually gets the best airplane for the money, giving you years of enjoyment in the future.

  • Picking Up an IFR Clearance

    Picking up an IFR clearance at first can seem very simple.  But, when taking off from an untowered field, especially if a pilot is based at a towered airport, it can be a little more complex.  Based at an untowered field?  The towered procedures are a little more streamlined, but still different.

    Towered Airports

    Class B or Class C

    At Class B or Class C airports, there is a dedicated frequency to get an IFR clearance and VFR departure instructions called Clearance Delivery.  It is published in the airport facilities directory as well as most approach plates.  Before you call Clearance Delivery, get the ATIS and tell the controller you have it as well as where you are located on the airport.

    CRAFT

    Class D

    Some Class D airports have a Clearance Delivery frequency (see KADS, Addison, TX), but for the most part, you’ll get your IFR clearance on the Ground frequency.  If there is a dedicated Clearance Delivery frequency, the ATIS will specify whether or not to get your clearance on it or on ground control.

    Class D towers are only part time towers, usually closing between 7pm and 10pm local time, depending on how busy the airspace is.  These airports usually have published Clearance Delivery frequencies to contact either the local approach control or center to pick up an IFR clearance on the ground.  They will be published on approach plates and in the A/FD.

    Untowered Airports

    Class E

    There are a number of Class E airports that are Class E all the way down to the surface (see KLFK, Angelina County).  At these airports, there will either be a Clearance Delivery frequency or you call on the Center or Approach frequency to get your clearance (at KLFK, you call Center as there is no Clearance Delivery frequency.  At Temple, KTPL, there is a published Clearance Delivery frequency which you would be talking to Grey Approach).

    Class G

    There are two ways to pick up an IFR clearance at a Class G airport, one typically a little safer than the other.

    The first option is to take off and maintain VFR while calling Center or Approach control.  They will give you your clearance making you IFR and allowing you to enter the clouds.  This option can be unsafe depending on the terrain surrounding the airport and how low the ceiling is.  If the ceiling is overcast at 1,000, you can legally remain VFR in Class G airspace at 500 AGL, but that isn’t the safest option and you might not be able to raise ATC at that altitude.

    The second, and safer option, is to call on the phone.  Flight Service has a nationwide Clearance Delivery phone number that every pilot should have saved in their contacts (888-766-8267).  Typically, you want to wait to call them until after you are done with your runup because they only give you a five or ten minute window to get off the ground.  With bluetooth equipped headsets, this usually isn’t a problem.

    Be prepared when calling Clearance Delivery on the phone to wait a few minutes.  Us pilots aren’t good at being patient sometimes, but the FSS has to call Center on the phone to get your clearance and release and this can take a few minutes.  Be prepared for that going in and just be patient.  Remember, this is the safer option!

    There are a handful of Class G airports around the US that have a GCO, a Ground Communications Outlet. With a GCO, you tune up the frequency, then click the mic 4 times to talk to ATC or 6 times to talk to FSS.  Each mic click must be at least one second, so if you click the mic too quickly, it won’t work.

    At certain airports that are underlying an approach control’s airspace, you can actually call the TRACON directly and get your clearance from them (5C1, the Boerne Stage Airport, for example.  San Antonio approach is the controlling agency and you can call them directly to pick up your clearance).  It’s a good practice to get the TRACON phone number and save that in your contacts as well.

  • Dallas Airspace Changes

    As was the case with the Class B Airspace around Houston several months ago, the Class B Dallas airspace has been overhauled as well.  These changes were implemented at the last database update on September 18th.  If you’ll be flying into any of the Dallas airspace airports IFR, make sure you have current charts and your GPS databases are updated.

    According to AOPA, 14 SIDs and STARs were deleted, a number of new procedures were added, and changes were made to most of the other remaining procedures.  The new procedures in the Dallas airspace consist mainly of RNAV procedures for turboprops and jets, so most GA aircraft won’t be affected by those.  The legacy procedures that remained in place over went changes, including new frequencies, so piston aircraft going into the Dallas airspace are still affected.

    From AOPA, departures from Dallas Love (KDAL) that file their flight plan with special equipment /G in their flight plan will automatically be given an RNAV departure procedure.  This does not appear to affect piston aircraft as all the new RNAV SIDs in the Dallas airspace are for turboprops or turbojets.

    The reason for the changes to the Dallas airspace?  Similar to the changes in Houston, these airspace changes are meant to streamline departures and arrivals in the Dallas airspace area, reduce controller workload, and give continuous descent angles for arriving high altitude traffic.

    Don’t be surprised the next time you are in the Dallas airspace area if you receive a clearance that states:  “Descend via the arrival.”  In that case, just check the chart and aim for the appropriate altitudes at the appropriate fixes.  As we move closer to the ADS-B requirement, I believe we will see more and more of these terminal procedure overhauls, so be prepared and keep those charts and databases up to date.

  • Cirrus Autopilot Check

    In the Pre-Takeoff Checklist for any Cirrus aircraft, it calls for pilots to perform a Cirrus Autopilot Check.  It is prudent to check the autopilot before your flight to ensure that all aspects of the autopilot are working properly.  The only problem is, the checklist doesn’t spell out how to perform the Cirrus Autopilot Check.  You would have to go to the POH for the airplane, which is usually in the back seat or a bag somewhere and therefore hard to get to, in order to find the procedure.

    The procedure for checking the autopilot is slightly different depending on what autopilot is in your airplane.  The procedures for all three are below.

    S-TEC 55x

    • Sync the heading bug to your current heading
    • Activate heading mode on the autopilot
    • Twist the heading bug left and right to ensure the ailerons move left and right
    • Sync the heading bug to your current heading
    • Activate vertical speed mode on the autopilot
    • Move the vertical speed bug (or the vertical speed on the altitude pre-selector if you have a steam gauge Cirrus) up and down to ensure the elevator moves accordingly
    • Ensure you can overpower the autopilot
    • Press the autopilot disconnect switch to ensure the autopilot shuts off

    • Press the AP button to activate the autopilot
    • Ensure AP, ROLL, and PITCH Annunciations are depicted in green on the top of the PFD
    • Set the heading bug 90 degrees from the current heading
    • Press the HDG button on the autopilot
    • Ensure the ailerons are moving in the proper direction and HDG is annunciated on the top of the PFD
    • Ensure you can overpower the autopilot
    • Press the autopilot disconnect switch on the stick and ensure the autopilot has disconnected

     

    DFC90

    Garmin GFC 700

    • Press the AP button to activate the autopilot
    • Ensure you can overpower the autopilot
    • Press the autopilot disconnect switch on the stick to ensure the autopilot has disconnected
  • Flying WAAS GPS Approaches

    When flying a WAAS GPS approach, there are several different levels of WAAS signal that a GPS receiver can get. The most precise is an LPV signal. LPV stands for Localizer Performance with Vertical guidance. An LPV approach has the lowest minimums of all the WAAS GPS approaches, typically in the range of 200-300 feet AGL. A GPS glide path (GP) is guaranteed with an LPV approach and the minimum altitude is a decision altitude (DA).

    Just like a localizer, an LPV course width get’s tighter and the CDI becomes more sensitive the closer the plane get’s to the runway. Even though the LPV approach minimums are so low and the approach is down to a DA, they still aren’t considered precision approaches by the FAA (which leads to some extra planning when selecting an airport as an alternate that only has GPS approaches, since the AIM specifies only the LNAV minimum are to be considered if an alternate airport only has GPS approaches, bringing the 800 foot ceiling requirement to bear)

    An LNAV/VNAV approach is still a WAAS approach that has a GPS glidepath, but is slightly different than an LPV approach. An LNAV/VNAV final approach course does not get more sensitive the closer the plane gets to the runway. The smallest course width on an LNAV/VNAV approach is 0.3 miles either side of center. LNAV/VNAV approaches will, most of the time, have higher minimums than LPV approaches and can have minimums no lower than 250′ AGL.

    The third type of WAAS approach is strictly a non-precision approach with a Minimum Descent Altitude (MDA). These are designated LP approaches, which stands for Localizer Performance. These are like old school Localizer only approaches that, similar to the lateral portion of an LPV approach, the course width tightens the closer to the runway that a pilot is. There is no glide path by definition of an LP approach, though there is a caveat.

    Now, by looking at an approach plate that is a WAAS approach, but only has LP minimums listed, a pilot would assume there would be no glide path. Depending on what type of GPS unit the airplane has, that pilot could be wrong. Garmin Perspective units (Cirrus G1000), all GTN 750s and GTN 650s, All G1000 NXi units, most Garmin 430W and 530W, and all Avidyne IFD 550/540 and 440 units will display an advisory glide path on an LP approach, designated LP+V.

    What does LP+V indicate? An advisory glide path is just advisory, but it is totally legal to follow down on a non-precision LP approach. The kicker is obstacle clearance is not guaranteed and the pilot needs to keep an eye on minimum altitudes at the different waypoints on the approach. The big thing I tell people is, when you arrive at the MDA and the runway is in sight, following the advisory glide path below the MDA could get you in trouble with obstacles. Don’t just hone in on your instruments when you break out of the clouds. Look out the windscreen and make sure you won’t hit anything.

    If you arrive at the MDA on the advisory glide path and the runway isn’t in sight, DON’T GO BELOW THE MDA! Most autopilots won’t level off at the MDA, even if that altitude is set in the altitude pre-select, so this will involve turning off the autopilot before the MDA and manually leveling off, or engaging the altitude mode of your autopilot at the MDA.

    One other type of GPS approach that you will encounter is an LNAV approach. This is a non-WAAS approach down to an MDA, but your GPS unit may still give you a +V. Most modern ones will.
