- During flight, the sign which indicates the trouble of the APU (Auxiliary Power Unit) battery was displayed on the cockpit indicator. However, the voltage and electrical current were within normal range and there was no effect on remainder of the flight.

- After the arrival at Tokyo (Narita), the inspection of the APU battery revealed that there were no abnormalities such as smoke or overheat.

- The sign of trouble went off after the replacement of the APU battery and the battery charger. Then the functional test for the airplane battery system conducted and it was confirmed that the system functioned normal.

- The inspection for the removed APU battery is in progress. No abnormalities are found so far. The inspection is continued.

- During turn-round inspection between previous arrival and next departure, it was found that the indicator which showed the difference in pressure between inside and outside of the APU (Auxiliary Power Unit) battery enclosure box has activated, therefore the inspection was conducted.

As the result of the inspection, no battery failure was observed, but it was found that the two small holes (*) which were bored on the battery enclosure box were both obscured by tape. The relevancy between holes obscured by tape and the indicator activation is under investigation.

This situation does not affect the battery system function or the gas venting function.

(*)The holes are designed to equalize pressure between inside and outside of the battery containment box.

The Action for the Emergency Locator Transmitter

July 26, 2013

The airworthiness directive (*1) mandating the removal or the inspection of the 787 fixed emergency locator transmitter (*2) (ELT) within ten days was issued on July 26 relating to the smoke incident which occurred on the other operator's 787 at London Heathrow airport the other day.

JAL has already completed the inspection of the ELT for all 787 fleets in compliance with the Boeing recommended procedure and confirmed no defect. Therefore, JAL operates all 787 normally.

In case the Boeing, etc. requires an additional action, it will be performed promptly.

We will ensure safety in operations of every flight so that our customers can fly JAL at ease.

*1    If the Japan Civil Aviation Bureau (JCAB) determines that modifications or inspections are needed to ensure safety of an aircraft or components, it issues a directive which orders to take action to the owner of the aircraft.

*2    The equipment which automatically transmits distress signal if a high deceleration is sensed.
By tracking this distress signal, the transmitting location will be pinpointed and the search and rescue activities will be carried out smoothly.

 

 

 

The Verification Results of the Battery System Modification 

August 9, 2013

Some batteries are routinely removed and inspected to verify that they are functioning soundly (sampling inspection), in collaboration with the Japanese Ministry of Land, Infrastructure, Transport and Tourism, Civil Aviation Bureau, another Japanese operator, and Boeing.

As three months has passed since resumption, one APU (Auxiliary Power Unit) battery (*1) and one main battery (*2) were removed from 787 and the following inspection was conducted to them recently:
  (
*1: removed from JAL 787, *2: removed from Japanese other operator 787)

- Battery test and cell inspection, specified in the battery maintenance manual

 As the result of the inspection, no defect was found on these APU and main batteries.

JAL and another Japanese operator continue to inspect the Batteries routinely and verify the results of the battery system modification.

 

The Verification Results of the Battery System Modification (Second Time)

November 15, 2013

Some batteries are routinely removed and inspected to verify that they are functioning soundly (sampling inspection), in collaboration with the Japanese Ministry of Land, Infrastructure, Transport and Tourism, Civil Aviation Bureau, another Japanese operator, and Boeing.

As six months has passed since resumption, one APU (Auxiliary Power Unit) battery (*1) and one main battery (*2) were removed from 787 and the following inspection was conducted to them recently:
  (
*1: removed from JAL 787, *2: removed from Japanese other operator 787)

- Battery test and cell inspection, specified in the battery maintenance manual

 As the result of the inspection, no defect was found on these APU and main batteries.

JAL and another Japanese operator continue to inspect the Batteries routinely and verify the results of the battery system modification.

 

Smoke Emission at Narita Airport

On January 14, 2014, at Tokyo (Narita) airport, the white smoke was emitted from Boeing 787 for JAL707 (bound for Bangkok) at pre-departure maintenance. Also, the message which indicated the possibility of main battery system failure was displayed on the cockpit display. The inspection revealed that there was one failed Lithium-ion battery (cell) in eight batteries in the battery case and the safety mechanism (pressure relief valve) of failed battery was activated. It shows that the electrolyte vaporized with some sort of reason.

Seven cells other than failed one are not in the state where the safety mechanism (pressure relief valve) needs to activate. Also, the white smoke was evacuated to the outside through the dedicated duct and the white smoke never flowed into the cockpit or cabin as intended.

As just described, the modifications made to the battery system were functioning, so the safety operations are ensured.
The cause of the smoke emission is investigating in cooperation with the parties concerned.

We sincerely apologize to the passengers and the related parties for the inconvenience and concerns by this event.
