Where Impactor Check is applicable?

[Rodrigo Mourão]

Hey guys,

Does somebody know where the verification of the impactor check is applicable?
I mean, this is applicable in the part over the motor and behind the pilot?

I ask this because this parts has a big space among the tubes and the template does not touch no one.

Thanks, see u soon..

"Impactor Check - must not be able to enter frame at any point between front bulkhead and main roll hoop - must contact three points of frame everywhere in side projection


AF6.2 The impactor is a 3-dimensional requirement. It applies to all faces of the structure, including the
front, sides, top, floor and rear, excluding only the cockpit opening specified in B4.1."

Did you consider the rulebook?

Ya, i read the rulebook, but if i understood it all, i don't ask you, right?

However, thanks friend.

Sorry, I just thought the wording was pretty clear. The impactor must not be able to enter the frame between the bulkhead and rear rollhoop. Ala anything behind the RRH (assuming your engine and the area you are referring to is) would be OK
