The FAA announced on 11 August 2008 that it would investigate why "almost half the masks either did not deploy or failed to provide oxygen" during a pan-pan event on American Airlines Flight 31 The FAA had recently issued airworthiness directives regarding problems with defective inline flow indicators obstructing the BE Aerospace oxygen masks on several Boeing commercial aircraft models. B/E had identified a repair in February 2006. Boeing then issued a "Special Attention Service Bulletin" to inspect and if necessary repair the masks in April 2007. The directives only require action by April 2013 unless already done.

Rockwell Collins, a manufacturer and supplier of aviation and integrated solutions for both commercial and government applications, filed for regulatory approval for its intended acquisition of B/E Aerospace before the Philippine Competition Commission since the latter has a branch in the Philippines operating a manufacturing plant in Tanauan, Batangas.

As a result of the acquisition, a newly created direct or indirect subsidiary of Rockwell Collins, Quarterback Merger Sub Corp., will merge with and into B/E Aerospace, with the latter surviving the merger as a direct or indirect subsidiary of Rockwell Collins.
