Incident: Jetstar B788 near Osaka on Mar 29th 2019, both engines
temporarily rolled back
A Jetstar Boeing 787-8, registration VH-VKJ performing flight JQ-15
from Cairns,QL (Australia) to Osaka Kansai (Japan), was descending towards Osaka
when the leftt hand engine (GEnx) rolled back for a couple of seconds before
recovering. Shortly afterwards the right hand engine rolled back for several
tens of seconds and recovered, too. The aircraft continued for a safe landing on
Kansai's runway 24R.
The aircraft is still on the ground in Osaka on Apr 2nd 2019, about 103 hours after landing. On Apr 2nd 2019 Japan's Ministry of Transport reported the occurrence was rated a serious incident and is going to be investigated. Both engines temporarily lost thrust about 90km/50nm south of Oskala. The JTSB have dispatched three investigators on site and opened an investigation (editorial note: however, the JTSB has not yet published such information on their website, standing Apr 2nd 2019). According to ADS-B data the aircraft was descending through FL200 about 50nm south of Kansai Airport.

At approximately 15,000 feet during descent into Kansai International Airport, Osaka, Japan, the flight crew of Jetstar Airways flight JQ15 received an engine thrust warning on the number 2 engine, which subsequently started to surge. The crew then received an engine fail indication on the number 1 engine, without any shift in parameters indicating any engine power loss. That warning was followed by an engine fail warning on the number 2 engine. The number 2 engine auto relight activated and the engine continued to surge during the descent. |
