As per my original posts on this subject, the Mod is reactive rather than
constructive.
A properly run company would have taken this in house and worked with
the LAA and AAIB to create a solution proportional to the issue. A mandatory
SB issued by the LAA amounts to an MPD in plain anguage.
The solution adopted is technically very poor. It is also very ugly.
The root cause of doors coming off the aircraft hasn't been addressed. The 3d
printed solution will, l suspect, not prove to be sufficiently robust. Those
who have opted to follow Iss 1 of the Mod now have closely spaced holes adjacent
to a load high spot (door frame aperture), as pointed out by Area51 this could
lead to degradation of the primary structure.
I am progressing an alternate Mod that utilises a cross drilled hole in the
front
latch pin, secured manually by a short pip pin and pendant. This is a positive
lock that prevents the front pin from sliding backwards, thereby making the
status of the rear pin irrelevant.
Following the Iss 2 of the Mod allows the bonding of the mouldings to the
aircraft
skin. This mitigates the possibility of crack propagation but makes no
difference
to the Ugliness.
