New nests for our birds

Now that Galvin Flying has closed its doors, you may wonder where you can find our aircraft for training and rental purposes:

  • Twin Stars
    • N238US has been moved to BEFA in Renton (RNT), and should be available to you shortly
    • N16ES has been moved to Intercept Aviation in Portland (PDX), and after an initial 100hr inspection will go into service very soon
  • Skyhawk N513WF will also go to BEFA, but the repairs related to the unwanted kiss from a Gulfstream still need to be completed – that might still take up to a couple of weeks, but we’re obviously doing everything we can to make her available again to you ASAP!

Let us know if you have any questions!

N513WF out of service until further notice

While performing run-up tasks at BFI/A2, 3WF’s left wing tip got hit from behind by the right winglet of a Gulfstream business jet taxiing south-bound on Alpha on 9/20.

The left aileron and the areas around it are badly damaged, and the plane is currently not airworthy. It will likely take until the end of 2024 before this plane can be back in operation.

We will let you know when the repairs are done and 3WF is back available to you.

Hey… remember Va..?

Va – aka design maneuvering speed: the maximum speed at which full or abrupt control movements may be used without overstressing the airframe is becoming more important again anytime warmer air will lead to more turbulence.

The moment things get more than just a little bumpy, make sure you slow down to or below Va for the weight of your flight – which is likely less than max gross weight, meaning that the Va you should not exceed is also less the one on the panel:

  • C172 Va : in case of doubt reduce power and slow down to <= 90!
    • 2,250 lbs: 105 KIAS
    • 2,200 lbs: 98 KIAS
    • 1,900 lbs: 90 KIAS
  • DA42 Va : in case of doubt reduce power and slow down to <= 120!
    • Above 3,400 lbs: 126 KIAS
    • Below 3,400 lbs: 120 KIAS

Here is what happened to an aircraft that crossed a front, and suddenly hit turbulence well above Va:

Easy on the brakes, please..!

We’ve had yet another tire blowout in a DA42 on a runway after landing… and because the other main tire (a pretty new one) also ended up with a flat spot, both main tires had to be replaced – don’t be that guy!

This is a gentle reminder that the DA42 brakes are very effective, and need to be applied gently.

After touchdown, apply aerodynamic breaking first (once the nose wheel is on the ground, hold the stick back) while gently breaking until you’re at or below 50 KTS – only then should the brakes be applied with a little bit more force.

Max breaking upon short field landing practice should generally be simulated (you announce it, but brake normally), unless of course it actually is a short field (though it’s generally not recommended to land on runways less than 3,000′ in the Twin Stars).

If TWR assigns you a certain exit that you cannot comfortably make with three wheels on the ground then just say that it will be the next one.

Please be advised that costs caused by unnecessary tire abuse will have to be billed back to the PIC – two new tires + work ain’t cheap..!

DA42 Fuel & Oil

This is an older post, but appears to be in need to be recommunicated:

  • Fuel: If an FBO asks you if you want Jet-A Negative or – the slightly more expensive – Positive, you should always ask for Jet-A Negative.
    • Positive means that an anti-freeze agent is added to to the fuel, which is unnecessary in a light twin unless you fly at -40°C or even colder flight levels – which is extremely unlikely, even in the deepest winter
    • At some FBOs only positive is available – in those situations, if you do need fuel then of course that is what you need to order
  • Oil: When you measure oil, before the necessary second oil dip for the reading you must screw the oil dip all the way back in (and of course wipe the dip stick!)
    • Yes, it’ll cost you valuable milliseconds – but you will get a correct reading. Not screwing it back in will show too low an oil level, which typically results in subsequently overfilling the oil tank, which is not economical and can easily lead to unnecessary MX to figure out where oil drippings are coming from
    • If you end up adding oil from a bottle you found in the nose compartment, please note that that bottle is already paid for, and don’t log it again as ‘Oil used’ in the post-flight form (as that will assume you grabbed a bottle from the oil room).

Thank you very much for your continued business!

Twin Star gearbox oil level inspection

The gearbox oil level of the CD-135 engines of our Twin Stars is inspected through a small round glass at the prop end of the engine.
We have newer gearboxes on both DA42s: the oil level does not need to be at the top of the glass, but the level is correct when the oil covers (at least) half of the inspection window:

So if you see it at just about half, you’re good to fly!

OIL TEMP on departure

All engine instruments need to be in the green prior to departure. On cooler days – or on the first flight of a day – in can take several minutes all the way into the runup phase before the oil temperature is in the green.

With the Twin Star, insufficient oil temperature can also lead to the ECU TEST buttons having no effect during runup.

Please be patient, and wait that extra minute or so before proceeding with the runup so that you have a safe flight – treat any aircraft engine like your life depends on it!

ESP

3WF is equipped with Garmin’s Electronic Stability and Protection safety system which is activated by default every time you turn on the avionics.

For any and all training flights with the intention to practice flight maneuvers please make sure to deactivate ESP (see the Pre-/Postflight section at the top of the Before You Fly 3WF… page) so as to avoid ending up in a fight with the Autopilot.
The feature will turn itself back on for the next flight, so don’t worry if you forget to re-activate it.

If you intend to fly X/C without maneuver practice there is no action item; ESP will simply be automatically ready to assist should the need arise.

For more information about ESP see chapter 8.10 in the G3X Touch Pilot’s Guide.
