Dave...
It seems a fairly typical pattern that they break off with minimal serious corollary damage
I would stand by that, but clarify my remarks by "serious" meaning in terms of flight safety / hazard. In neither case was any serious control / handling or management aspects apparent in the reports, indeed the AW report:
The return for landing at the departure airport at 1331 was unremarkable.
and the serious damage amounted to:
and there were 3 holes in the lower surface of the left horizontal stabilizer, each approximately 2 inches wide and 8 inches long. The cowling door hold-open rod penetrated the lower skin and aft spar web of the horizontal stabilizer
I am not suggesting this is "satisfactory", just there has not yet been sufficient impetus for the industry/regulators to fix this problem.
We shall see if Friday's events and pattern stand out enough to get this fixed?
