How can I define RegEx to remove a particular part in a specified line of code?

I am attempting to remove .nc1 at the end of a line. I receive .nc1 in batches as a steel fabricator. We run into issues with our files where, line 5 in the example below, has an unnecessary .nc1 extension at the end. Problem I have, is that I cannot simply replace the value as it appears in line 2 as well.

In the example photo I have attached, I am looking to remove line 5 .nc1 extension and keep line 2 as is, .nc1 extension removal will be applied in a batch editing to all of my .nc1 files via find/replace.

ST
** BB233.nc1 
  F88 
  BB233 
  BB233.nc1 
  1000
  A992
  1 
  W21X201

Change to this

ST
** BB233.nc1 
  F88 
  BB233 
  BB233 
  1000
  A992
  1 
  W21X201

I was looking into Positive and/or Negative lookahead/lookbehind but didnt have much luck in making it work. I am a novice/lack thereof when it comes to using RegEx.

I am using Text Crawler 3 to help with editing the files

Match .nc1 only at the end of lines starting with whitespace, capturing the part you want to keep and putting it back, effectively deleting .nc1

Search: ^(\s+.*)\.nc1$
Replace: $1
