Can You Pass This Preflight Walkaround?

Boldmethod

Every flight should start with a good preflight. And yours starts...now.


  1. 1) You're checking out the maintenance logbook, and you see that the last annual was done on June 2nd, 2020. Today is June 25th, 2021. Can you fly?

    According to FAR 91.409, an annual inspection needs to occur within the preceding 12 calendar months from the date it was last performed. This means that you can fly the plane all the way up to June 30th, 2021 before it needs an annual.

  2. 2) You check your oil, and it's just under the low mark on the dipstick. Assuming you're a private pilot, can you top if off yourself, or do you need a mechanic to fill it for you?

    According to FAR par 43, (c) Preventive maintenance (6) "Lubrication not requiring disassembly other than removal of nonstructural items such as cover plates, cowlings, and fairings." is allowed by licensed pilots.

  3. 3) You're walking around the airplane and you see this. What is it?

    This is the static port for your pitot-static system.

  4. 4) If you take a fuel sample and there's water in it, where will it be in your strainer?

    If you have water contamination, it will sink to the bottom of your fuel strainer, because water is heavier than avgas.

  5. 5) You check your aircraft lights, and your red nav light is burned out. Can you fly during the day (VFR) with it inoperative?

    According to 91.205 (c) (2), approved position lights (nav lights) are required for night flight, but not for day. As long as you follow FAR 91.213 (or an MEL, if that's what you have), you're good to go.

  6. 6) Finally, you hop back in the cockpit and get ready to start running your before-start checklists, when you notice that your panel-mounted clock isn't working (this preflight isn't going very well). Can you fly during the day (VFR) with it inoperative?

    According to 91.205 (b), you don't need a clock for daytime VFR flight. So as long as you follow FAR 91.213 accordingly, or follow the MEL it if you have a minimum equipment list, you're good to do.

Well, those were some tough preflight questions.
