In fact it is a very good example of the perils of operating an aircraft that was certified to old rules.
The aftermarket windshield was only designed to early 1970s bird strike standards and that is why the accident happened. Things would be different on an AB139 (for example).
Aftermarket being the operative word.
Had the original laminated glass windscreen installed by the OEM at build not been removed and replaced with a None-OEM approved cast acrylic windshield limited to only 109 knots and never tested for this model, then I don’t believe the outcome would have been anywhere near as severe, so not so much to do with with the aircraft being certified to old rules.
