Luke Andrew Flatters, 25, of RAF Coningsby, has been fined £800 after pleading guilty to sexually touching a woman aged 16 or over without her consent in February.
Flatters indicated his guilty plea at Lincoln Magistrates’ Court on March 31, and was sentenced at the same court on September 16.
In addition to the £800 fine, Flatters was ordered to pay £85 in court costs and an £80 victim surcharge.
It was ordered that a requirement to register with the police, imposed on August 26 by Lincoln Magistrates’ Court, was ended with immediate effect.
No compensation was ordered, as it would have served as a reminder to the victim.
