Paul B., Houston, TX
Installed a Door-Seal from: http://www.aero-pma-parts.com/
Paul said the
following:
In 2003 or 2004, I
purchased a seal that goes on the fuselage from another door seal
company. I spent hours removing the old door seal on the door, so the
door channel was clean.
I ordered a dual
air-chamber seal (AvTek/Aero-Pma-Parts) in December 2007. I recently
removed the old seal from the fuselage and installed the new seal on the
door.
I have flown with
it a few times already, and the seal is very tight in flight! The
hissing noise I was used to is gone…that was there with the Airframe
mounted door-seal.
The
fuselage-mounted seal is designed to compress as much as necessary after
initial installation, and then to hold that compressed state. On the
ground, that is fine. But, in flight, as the door is pulled out slightly
due to suction, a gap forms between the door and the seal.
The
Airframe mounted Door-Seal
that I discarded made and sold by another company NOT Aero-Pma_Parts/AvTek, maintains its compressed state by design.
While...
The door-mounted Air
Chamber
Seal (Aero-Pma-Parts/AvTek) is different.
It compresses when the door is
closed, but when the door is opened, (in-flight due to differential
cabin pressures it expands to its original size.
So, when the door is pulled out slightly during flight, this seal
expands slightly to fill the space, so no gap is created.
