Heavy smoke was reported in the cargo area of a plane that had just arrived from Japan at Logan Airport on Monday morning.
The smoke was spotted by a mechanic coming from the cargo area of a Japan Airlines Boeing 787, which arrived at Logan just after 10 a.m. on Monday, according to Boston fire.

The fire, which happened while the aircraft was parked at a Terminal E gate, is believed to be electrical, according to Boston fire.
The area where the smoke was spotted is where batteries used to power auxiliary avionics are housed. That system is activated after the aircraft's main power is shut down.
No passengers were on board at the time.
One Massport firefighter was injured during the incident, but the extent of the injuries was not immediately known, according to Richard Walsh of Massport.
The aircraft had arrived from Japan at 10:06 a.m. with 184 passengers and crew on board, and was scheduled to return to Tokyo at noon. That flight, Japan Air flight 7, has been canceled.
The 787 has had three reported problems with the plane’s electrical system since it went into service last year, according to KING.com.
