I assisted on a pre-buy on an airplane that my IA said "a walk around is pretty much an annual", yet in reality it took about 5 hours to actually go through EVERYTHING. A couple special tools that I'm pretty sure TSA would not be happy with, and a long sit with papers dating to before my father was born. Some things are just not reasonable to check on a pre-flight. You do a compression check on the pre-flight of a piston? Because that is a crap ton more telling than making sure the lights work. How about an oil analysis? That will tell you when bearings are going or if you have corrosion on any internal part and which part. While we're at it, lets change the oil filter, and cut open the media on the old one and look for metal.I also see other idiots trying to be funny about something serious, SMH.
All of those things are kind of ridiculous on a pre-flight. So is getting out a 40-200ft ladder to check the top of the horizontal stab. The act of checking the stab is going to be more dangerous than assuming mx did their job and it's fine.
I don't think there's even a part 23 t-tail twin you can check it.I have yet to fly an airliner - including the cited accident aircraft, which was a Brasilia - in which I can inspect the upper surface of the horizontal stabilizer.
