This is a question for those of you who are flying your IV-P's with
pressurization operative.  The factory construction manual I have says to
install the fuselage side door seal, p/n SF14-1704.
It is called a modification and there are instructions to cut down an
earlier type seal to yeild the proper flange width.  I believe I have that
later type seal.  Reference figs 28:K:1, 2 & 3 in chap. 28 and the
instruction paragraphs.
Neither Hal Woodruff or I can remember seeing a seal on the fuselage of any
IV-P we have looked at.  Are we blind?  Is this seal not currently used?  Is
it better to leave it off?
Any and all comments are greatly appreciated.
Thanks in advance,
