I am looking for the name of a movie that I saw when I was a kid in the 70's, maybe the late 60's. See details please.?

A plane crashed in the middle of nowhere, and at night. On the way down it hit a baby Bigfoot and killed it. The survivors of the wreck found an abandoned cabin, and were tormented by the Bigfoot clan for some time. I would like to find that movie again, but have NO IDEA of the name. I am sure it was in the 70s or late 60s. NO later than 82 for sure. Certain I was younger, so probably closer to 72. Yeah, I tried google, found a lot of close things, but nothing to match. It was on TV, could have been 'TV only' release. Please tell me I am not losing my mind. Any assistance will be greatly appreciated.
