Doesn't look like a stock Apache tail but does resemble an Apache with the Geronimo conversion I believe.....but it's been close to 40 years since I flew one so memory may be flawed.
Possibly a low altitude engine failure. My fuzzy recollection of the Apache's s/e performance were that the function of the remaining engine was to take you to the scene of the crash and nothing more. Unfortunate but possibly true in this case.
