Squib all flying machines have some sort of compromise within own construction,
Mi 8 family too....
FYI AI-9 can be replaced with Saphire (PBS, EASA certified) APU,
no need for "collector",
and no just 3 start limit,
and ability to start up to 6000 m
and in flight run of air condition heat/cool
All is just question of few $ more
