Default Stamper RV-10 accident Preliminary Report

Door came open. Check out this prelim report:

http://www.ntsb.gov/_layouts/ntsb.av...05X23019&key=1

Have you RV-10 folks - and others with pop-up canopies - really developed a detailed step-by-step checklist for what you're going to do if something comes open?

Man, I really hate to see that. That's the one reservation I have about building a 10 for my growing family, is the door latch design.

Very sad. Fly the Airplane!

I recently posted about my flight instructor many years ago who would purposefully open doors, grab the yoke, open a window, close the throttle or mixture,... basically purposefully distract you until you no longer panicked.

It was also noted that in todays training environment, that instructor might have lost his job for this. Too bad. This was an avoidable accident.

Bottom line, Fly the Airplane.

Thanks for posting this as a lesson to us all.

As I have lost an RV-10 door due to a C130 prop blast, I'm sensitive to the issue. This is what I told the guy who bought my RV-10:

N7ZK?s doors have primary and backup locking devices, and the SkyView alarms if all four primary locking pins are not in place. The doors will last a lifetime if you don?t violate the rules:
1. Doors shut and locked before engine start.
2. Assume your passenger did not lock his/her door ? verify before engine start.
3. After engine start verify all four door pins in by observing the Green door indication on the SkyView EMS display.
4. Doors shut and locked anytime the engine is running ? no matter how tempting to do the hot passenger pickup/drop off.
5. If parked anywhere but in a hangar, doors shut and locked unless you are standing next to the door. So for all fueling, moving to park, etc. doors shut and locked. In other words, unless you are getting in or out of the plane, doors shut and locked.

Carl

Hey guys, there is already a thread on this here.

I'll defer to a another moderator or Doug himself if these should be merged or one deleted.

That one is a memorial thread and probably shouldn't be cluttered with details of the incident. IMO

Yes-it's only 2 steps:

1. Fly the Plane
2. Land Immediately.

Notice there are no steps about the door itself. I will make no attempts to save the door--period. If I've got pax and they have the wherewithal to do try something then they can, but I will only focus on putting the plane safely on the ground. YMMV....

I wonder if it is out of the question to think about moving the hinge points of the door to be along the front edge or angled so the door won't suck open? Like a Cirrus. (I admit I'm making an assumption here; I don't know for sure that Cirrus doors don't suck open).

There are plenty of flight-critical things that we as pilots must get right, or cope with the error while continuing to fly the airplane. And yes, I'm usually an advocate of the idea that it is OK to rely on the pilot to be sure to get it right.

But if a fairly uncomplicated engineering solution can save lives, why not?

Are there any reasons why it would be very difficult or impossible to relocate the door hinge points?

Unfortunately Steve,
Even a different opening action of the door doesn't always protect from accidents caused by a pilot allowing him/her self to become distracted.
The NTSB files are full of them.
Here is a high profile one that I am personally familiar with from when I lived in PHX....... https://aviation-safety.net/wikibase/wiki.php?id=37373

And yes I think it would be fairly complicated to move the hinge points. The fwd "A" pillars are considered rollover structure. Not that it couldn't be done, but there are numerous issues that would have to be dealt with.

So not to make assumptions, but based off the report, could it be that the door was never closed in the first place? I'm wondering if the annunciation system had a fault so he didn't realize it wasn't fully latched?

Either way, it's something we can all learn from wether it was a human or mechanical failure. Very sad that we lost a member of our flying family.
