A faulty defibrillator aboard an American Airlines flight led to a 14 year old's death, a new lawsuit claims

• Kevin Greenidge was 14 years old when he experienced cardiac arrest on an American Airlines flight.
• A lawsuit filed recently by the teenager's mother alleges the defibrillator on the plane wasn't working.
• Automatic external defibrillators have been required on commercial aircraft since 2004.

A 14-year-old boy went into cardiac arrest on an American Airlines flight, but couldn't be revived when a doctor tried to use a defibrillator on board, a new lawsuit filed by the boy's mother says.

The suit says the defibrillator was faulty — and places the blame on American Airlines.
