Aircraft Leasing Investment Trusts - too good to be true or not?

Hi Browsing ETFs and ITs looking for some high dividend funds to add to my largely growth focused portfolio, I came across Amedeo Air Four Plus and Doric Nimrod Air Three Ord. Their business is buying commercial aircraft and leasing them to airlines. They are both yielding approx 13% and the stock price, whilst volatile, shows reasonable growth over recent years. Obviously there are risks associated with the commercial airline sector and they both took a hit during Covid but that's a rare scenario. So, is there something inherently flawed with these ITs that I haven't figured out yet or are they worth a small allocation?
