Piston air cooled aircraft engines (and some liquid cooled engines like the Rotax) clearly last longer when oil change intervals are kept at about 35 flight hours or below. Yes, the manufacturers specify a 100 hour OCI, as it's safe. The reason for the more frequent OCI is, as always, micro particulates and the associated wear. Of course, the fuel is leaded, the oil is different and the engines have little in common with automotive engines. Even so, the oil change is the only way certain forms of contamination (such as fuel byproducts and micro particulates) can be removed from the engine.
Furthermore, UOA results are regularly performed by aircraft engine operators. The notion that UOA "wear metals" indicate a wear-rate is, at least in the aircraft industry, completely false. While it's just my opinion, I no longer put any stock into UOA "wear rates" as valid for any reason. Clearly, UOA results can be excellent and the engine a sludged up, worn out disaster.
The bottom line remains: Choose a quality synthetic oil, change it frequently and choose sufficient viscosity. Your results will likely be excellent. Contrast that with the 3.5L ecoboost owners who use 5W-20 non syn, change at 10,000 mile intervals, then complain when their timing chains are worn out at 100,000 miles. While other 3.5 EB operators choose something like M1, 10W-30 EP, change at 5000 mile intervals and get 300,000 trouble free miles from the engine.
