Gary,

If your IV/IV-P door was built by Lancair, or built = according to the instructions, the latches (3 for the IV; 8 for the IV-P) are linked = together with flex cable, and each “chain” of latches (one chain each = on the front, bottom, and back of door) ends with a 3/8” diameter bolt = that’s used as a rotating latch pin, and having a =BD” hex head. These = latches are covered with small trim pieces, typically held in place with #6 = phillips-head screws.


If any part of the linked-together latch mechanism breaks, it will leave = one or more latches closed, trapping any occupants inside. The trick is to = determine which latches are still fastened, remove the trim cover at the end of = the appropriate chain, and use the =BD” wrench to turn the latching mechanism from = that point.

 

Depending on what failed, you might be able to open the = door using other tools/methods (this has been done), but at least one IV-P has been = opened by breaking out a side window to free the trapped occupants. =

 

By the way, if you’re still building, consider = installing a 4-5” access hole, covered with an aluminum plate on the inside, = in your rear seat directly above the left gear leg. Hold it in place with = silicone sealant and a cross piece on the landing gear side of the seat bottom. = Make it removable from inside or outside the aircraft. Remove the plate to pass tools and = provide cooling air into the cockpit if you’re trapped on a hot = day.

 

Hope this helps.
