Pumpkin Bombing
There were threads of other people asking about pumpkin bombing in RVs, but no real answers. Has anyone been able to pull this off?

Pumpkin Bombing
This reminds me of a Gordon Baxter (Flying Mag) classic on STO'ing a stovepipe on a Cub to eject a cat at increasing altitudes to settle a bet on the survivability of the cat. Seems like a pumpkin would be more cooperative than a terrified cat making this a simple project.

Tom Martin installed a spear onto his wingtip that is hinged around a central bolt and held up by a car door central locking solenoid. The pumpkin is pushed onto the spear and the door lock retracted to drop the pumpkin which rotates the spear under its own weight until the pumpkin falls free.
From his post here...

Read your operating limitations closely.....
Latest version of operating limitations include the following statement:
15. This aircraft is prohibited from flight with any externally mounted equipment unless the equipment is mounted in a manner that will prevent in-flight jettison.

That's kind of a show-stopper...

I can launch small pumpkins out of this device. 
PS. Local FSDO came to look at it and put me back in phase 1 for 5 hours.

Hmmm. Since the FARs permit dropping objects as long as there's no danger to people/property, shouldn't this be parsed with an FAA-legalese-filter? That sounds like you can't jettison *the equipment*. That would not be the same as dropping 'objects'.
Not trying to be glib; there have been numerous instances where the FAA's language meant something completely different to them from what it would seem to mean to the average Joe upon 1st seeing it.

Seems like it. It would be a real stretch (IMHO) to call a pumpkin "equipment", any more than you would a roll of toilet paper. I think the pumpkin would be an "external load" and the mechanism would be an "external-load attaching means".

I think it is a dumb idea and could be very dangerous. Sorry for being a party pooper. Flour bombing is one thing. Hanging a 10+ pound pumpkin on a stick on the end of your wingtip is another.

No equipment being jettisoned here.
FWIW, there is no definition for "equipment" in FAR 1 1.1. It does define "external load" and "external load attaching". I note that "external load containers" and "any quick release device" is clearly not the jettisoned load itself *:
External load means a load that is carried, or extends, outside of the aircraft fuselage.
External-load attaching means means the structural components used to attach an external load to an aircraft, including external-load containers, the backup structure at the attachment points, and any quick-release device used to jettison the external load.
*your friendly FAA person may have an entirely different view if you land a pumpkin in the wrong place.
