Doors

[Guest]

Hi all,

Question about doors.

The pre-war B models had those smaller fabric covered lighter doors.

Post-wars have those larger aluminum or wood doors that are essentially put on the same frame as the the pre-war though so you end up with that tube along the back of the opening.

How are the F series doors made and frames? Do they also have tube in the back of the opening?

I had heard that the later models had this tube removed as it was unessary. Any truth to that?

I looked for an STC to remove it but found none. Anyone ever removed it (and survived)?

Thanks, Dave.

Re: Doors

They are a pain for sure but I suspect essential to the integrity of the airframe. If that brace wasn't there it would probably require additional structure elsewhere to compensate for it, so a Sawzall probably isn't a good solution. It is tempting though, isn't it?


By the way Drude the bungee cord tool worked fabulously. I tried to email you but it came back with permanent fatal errors. Software writers must get a kick out of the dire threats and warnings they feed us. If you cut out the brace in the doorway of the T-craft do you get a notice that "you have conducted an illegal operation?"

I have nicknamed the tube you are refering to as the "scrotum" bar. I warn all male riders of it's possible damage to ones anatomy.

Re: Doors

Just found an fuselage drawing and it is obvious that the tube must remain in place.

I thought I read or heard somewhere that it was redundant and was removed from F models.

If so they changed something else in the fuselage to compensate. Removing it alone would result in a permanent fatal error!

Re: Doors

The over-riding generalization is that a steel tube fuselage is easy and simple to design, but when you have to put in an opening for the pilot is when it gets tricky and complex.

Unfortunately I don't think you can just remove the tube. Even is the flight load path is redundant (which I'm not sure of), the tube will greatly increase the crashworthiness of the fuselage and so it should be there.

If getting "the runs" is Montezuma's Revenge, then the door openings on a T-craft is Taylor's Revenge !

Re: Doors

The tube was removed on the F-22 fuselage, adds 12 lbs... which included the adjustable seats.. I too am wishing it could go away as I got over 240#k
ER have the drawings here and an F-22 fuselage, come look!
