However, had such an event had taken place while the
aircraft was in-flight it would have been very difficult
for the cabin crew to put out the fire posing a
significant safety concern, given that the ELT is
located in the cabin ceiling, bind ceiling panels. As a
result AAIB issued safety recommendations.
1)
It is recommended that the Federal Aviation
Administration initiate action for making inert the
Honeywell International RESCU406AFN fixed Emergency
Locator Transmitter system in Boeing 787 aircraft until
appropriate airworthiness actions can be completed.
2)
It is recommended that the Federal Aviation
Administration, in association with other regulatory
authorities, conduct a safety review of installations of
Lithium-powered Emergency Locator Transmitter systems in
other aircraft types and where appropriate, initiate
airworthiness action.
Boeing reported "As a
party to the investigation, Boeing supports the two
recommendations from the UK Air Accidents Investigation
Branch (AAIB), which we think are reasonable
precautionary measures to take as the investigation
proceeds. We are working proactively to support the
regulatory authorities in taking appropriate action in
response to these recommendations, in coordination with
our customers, suppliers, and other commercial airplane
manufacturers. We are confident the 787 is safe and we
stand behind its overall integrity". (see
