    Lausanne-based TBM-3 Avenger HB-RDG ‘Charlie’s Heavy’ at Lelystad, The Netherlands this afternoon.

    The Catalina was on static display at an event at the Aviodrome today. It was towed there on its own gear, I couldn’t see any damage while taxiing past. That doesn’t mean it isn’t there of course, but it was good to see it on its own three wheels.

    Was the n/w neither up nor down..?Could it have splashed down,beached,fixed,refloat,return..?

    They knew that the gear was up but the doors were unlocked. As has been mentioned you run the risk of collapsing some bulkheads in the nose gear bay if you land on water like that. IIRC that’s what sank Plane Sailing’s first Cat.

    I can’t say that I’m a Dakota expert but on several taildraggers the technique you describe is a normal procedure on a soft field. Keep the stick back (or at least the nose high) until you lift off in ground effect and accellerate before climbing away.

    AFAIK the wings on a BD-5 are removable, but not foldable. So that would make this a modified version for the movie. The BD-5J that flew for the Bond movie is supposedly on display at the Pima Air & Space museum. Could this be the one that was used for the shots on the ground?

    I’ve seen it at Brooklands, although I’m not sure that it lives there. I know the other two vehicles do so it wouldn’t surprise me.

    There is an airworthy one at Lelystad, The Netherlands, but I think it hasn’t flown much (if at all) for the past two years or so due to issues with money and crewing. Someone else will surely be along soon to correct me on this 😉

    Fournier Boy, thanks for your additional information. I was basing this on US rules as I am not that familiar with the UK guidelines in this respect. As we are talking about a US type I figured that the FAA background would still be relevant. From what you explained, it seems that the original certification basis and approved mods are still the reference for any changes that you would like to make to your warbird. Unless you go to the trouble of having a Part 21 organisation develop a modification.

    From the article posted by TonyT (and as mentioned by JohnTerrell earlier on), it seems that this is what was done to get an airworthy prop for the two F-82s currently under restoration. But please note that although the prototype MT F-82 prop was flown on P-51A “Polar Bear”, this was only part of the process to get the prop certified. It does not mean that a Mustang prop is available, although if you phone MT props, I’m sure they will happily quote you a price to get one. You would then have to go through the same process to get that one certified.

    But as there are flying RR-Merlins with a composite prop, why shouldn´t a PA-Merlin not be able.

    An aircraft type is certifed with a specific engine and prop combination, which is specified in the Type Certificate Data Sheet or TCDS. So it is not a question of whether a prop works on another Merlin installation, it is a question of whether that type is certified to fly with a specific prop, in this case a wooden one. If you do want to install a composite prop on a P-51, then you need to get a Supplemental Type Certificate that allows you to install the new prop on this specific type. Even though there may be advantages to a wooden/composite prop, the hassle to organise this probably doesn’t weigh up against the availability of new or new old stock P-51 prop blades.

    For P-51s, as far as I know you can either register one as an Experimental or use the Limited Type Certificate that was originally held by Cavalier (now by Cal Pacific). This document is available here: http://www.calpacificairmotive.com/SubmittedToDesignServices/image/LTC-11__rev_5.pdf (see the bottom of page one for the allowed engine/prop)

    Because that is the prop it is certified with I would guess.

    Sorry, just had to copy this from the Yakfire/HurriYak image:

    …and it is not always immediately apparent that these are not photographs of genuine Hurricanes and Spitfires.

    I have a slightly different opinion on that! :p

    Still, a good effort!

    Fokker F.XXXVI PH-AJQ (Kwikstaart) suffered a double engine failure on take off from Schiphol July 14th, 1935 and hit a dyke in the return to the field.

    *cough* Fokker F.XXII *cough* 😉

    Archer: The feathering gubbins on PR is an electric pump. Don’t know if that’s from a Shackleton, I was under the impression it was a custom set up.

    It probably is, and I’m not sure which specific parts are from a Shack installation and which ones aren’t. When VP441 was first flown someone mentioned that the ex-Shack feathering option was retained and I assumed that PM would have a similar installation. The Seafire most likely also has an electric pump as a broken engine doesn’t deliver all that much oil pressure. You do need the correct hubs though, those are most likely from a Shack.

    Apparently you can’t feather the prop on a Mustang. I just found an old thread on it.

    On 98% of single engined aircraft the prop can’t be feathered, usually the hub is designed to move to full fine when oil pressure is lost (so that it is ready for a go-around). This may be different on older props though.

    The two exceptions I know of are Precious Metal (as already mentioned) and Seafire 47 VP441. Both use an ex-Shackleton Griffon and prop and as that had a feathering option available anyway it was left operational. You have to keep in mind that a prop that is able to feather is just one more thing that can go wrong.
