HOUSTON (AP) - India's Jet Airways says it has grounded its five Boeing 737 Max 8 aircraft after a crash in Ethiopia that killed all 157 people on board.

  

The airline said it is not flying any of the 737 Max planes in its fleet and is "in contact with the manufacturer."

  

On Monday, India's aviation watchdog said it ordered a safety assessment of the aircraft. It also issued safety instructions for flying Boeing 737 Max 8 aircraft.

  

The directions call for the pilot-in-command to have at least 1,000 hours of flying experience and the co-pilot to have 500 hours on Boeing 737 NG type aircraft.

  

Indian airline SpiceJet also has Boeing 737 Max 8 aircraft, but it's unclear if those planes are grounded. Calls and emails to the company were unanswered Tuesday.
