Both Calista and Carrie have reportedly begged the actor to take a break from his thrill-chasing hobby.
Harrison, 72, is expected to make a full recovery after crashing his vintage airplane into a California golf course last week.
The actor is a veteran pilot and has even assisted in two aerial rescues since qualifying as a pilot in the 1990s. However, his latest brush with death has prompted his wife Calista to put her foot down.
"It is a worry for her and his children that he has this dangerous hobby," a source close to the actress told The Mirror.
"Whether or not he will pilot a plane again remains to be seen but everyone around him certainly hopes he will take a break – or give it up for ever. It is obviously a huge worry."
Calista's not the only one worried about Harrison's safety - his Star Wars costar and close friend Carrie Fisher has also voiced her concern for the iconic actor.
"I know you have incredible bounce back, please take a bounce break for awhile. Can I drive next time?" she told People magazine in a statement directed at Harrison.
