Dentons is set to lose its aviation group in the U.S. to LeClairRyan, according to two people who follow the practice area. The group, which includes partner Mark Dombroff in Tysons, Virginia, is known for its representation of aviation industry clients after plane crashes.

It is unclear how many partners and lawyers will ultimately move with Dombroff. The group has notified Dentons of its pending departure, yet the lawyers had not left the firm as of Thursday.
