Boeing (BA) shares are plunging more than 5% after the aircraft maker guided 2014 earnings and revenue targets lower and warned about reduced profitability.

The Chicago-based aerospace giant is the biggest loser in the Dow and is responsible for half of the blue-chip index’s 107-point selloff.  

Meanwhile, Boeing supplier Triumph Group (TGI) is falling almost 13% after it missed earnings and revenue estimates last quarter, reported lower-than-expected margins and guided revenue lower. 

Other aircraft parts and systems suppliers are getting caught in the downdraft, including AAR Corp. (AIR), Esterline Technologies (ESL) (one of Barron’s Roundtable member Meryl Witmer’s picks in this week’s issue – ouch!), Spirit AeroSystems (SPR) and Rockwell Collins (COL). Shares of Boeing competitor General Dynamics (GD) are also taking a hit.
