The inside diameter of a zip tie is serrated. It can trap particles of dirt, and in a high vibration environment, these particles can abrasively cut through even solid aircraft grades of stainless steel. I saw the results when someone zip tied an instrumentation wire to a 5000PSI 21-6-9 stainless steel hydraulic tube on a GeNX-1B thrust reverser just to secure it out of the way during a test. It sawed through the tube and caused a massive leak after less than than 3000 simulated flight cycles (engine operating cycles on a ground test stand)
Zip ties have an annoying square head, and the tag end is often cut off not quite flush with the head, giving a great jagged edge to lacerate some poor mechanic's hand. I've frequently had my arm buried deep in a mass of spaghetti wiring behind a panel to get at a connector or something, it's very nice to not withdraw it and find deep red scratch marks in my forearms like I've been fighting to trim my cat's nails. They do sell a brand called Cobra Ties that have the tag end parallel to the band, which is a little nicer in this regard.
Zip ties are a hard point and are frequently over-tensioned. It's not uncommon to find damaged/pinched insulation, or even broken conductors in small gauge wires, under a zip tie.
In general aviation maintenance, I frequency (95% of the time inspecting a new to me airframe) encounter previous work that was accomplished with some garbage neon colored zip ties from the home improvement store or Harbor Freight, made of an unknown grade of plastic. When used in an engine compartment, these often cannot withstand long term exposure to high temperatures and fluids, and fail by breaking when you least want them to. When used in the passenger compartment, these can emit hazardous amounts of toxic fumes and smoke in the event of an electrical fire, which can be caused by an over-tensioned zip tie. Shade tree mechanics are too lazy (or ignorant) to mail order the correct MS3367 mil-spec ty-wraps, with guaranteed strength/temperature/flammability performance.
But really, I prefer wire lacing in the cabin, and MS21919 cushioned P-clamps in the engine compartment.
