I must say if there's enough good thread remaining I wouldn't generally be in a rush to fix it.
In this application though I guess it's seeing some load, and I heartily concur with Terry & Nick, a (properly installed) helicoil will be stronger than the original thread.
An alternative would be to tap it oversize, screw (& Loctite) in an alloy or perhaps brass plug, and start again. OK if you have lots of meat around the hole, maybe not in this case. A helicoil would be easier and stronger.
