Incident: Royal Brunei B788 near Manila on Oct 21st 2015, engine shut down in flight
A Royal Brunei Airlines Boeing 787-800, registration V8-DLB performing flight BI-684 from Manila (Philippines) to Bandar Seri Begawan (Brunei) with 152 passengers, was climbing out of Manila when the crew stopped the climb at FL280 reported the left hand engine (Trent 1000) had failed and was shut down. The aircraft returned to Manila for a safe landing on runway 24 about 50 minutes after departure.
The flight was cancelled.
The airline confirmed the Dreamliner's crew received abnormal indications for one engine prompting the captain to turn back to Manila for technical checks. A number of passengers have already been rerouted onto other flights, the remaining passengers were taken to hotels.
Philippines' Civil Aviation Authority reported the crew informed air traffic control the left hand engine had failed and declared emergency.

P { margin-bottom: 0.08in; } No underfire, you are wrong: the crew did not pray hard enough. Did not Mick the Mullah himself proclaim in the Holy Borneo Bulletin: “This airline is the flagship of the country, and the 787 is the best aircraft currently flying” (except for the HUD, which is the work of Satan).
Someone must be punished, they WILL pay! Disbelievers and evil-doers will be downgraded into the Grade B jahannam of the Airbus.

Today's press release from Royal Brunei Airlines.
Royal Brunei Airlines to face temporary flight disruption; Rolls Royce working to resolve engine defects on Boeing 787 aircraft
Oct. 28, 2015
On Wednesday 21 October 2015, Royal Brunei Airlines (RB) experienced a technical incident on flight number BI 684 from Manila Ninoy Aquino International Airport (MNL) to Brunei International Airport (BWN), operated by a Boeing 787-8 aircraft powered by Rolls Royce Trent 1000 engines. The aircraft experienced an inflight shutdown on one of the engines, just after takeoff and in accordance with normal procedures the captain decided to return to MNL. The aircraft landed safely and without incident and all 152 passengers were safely disembarked at the terminal.
Since then, Rolls Royce has conducted a detailed boroscope inspection of both engines as part of preparations to replace the affected engine, with a spare which has already been transported to MNL from BWN.
However, in recent hours information has been conveyed to the airline by Rolls Royce that the second on wing engine on this aircraft has itself being the subject of similar damage. The boroscope inspection has now revealed evidence of damage to a number of blades on both engines, for reasons which are as yet unknown. At this point, there is no evidence that an external event such as a bird strike has caused this damage to both engines. Efforts to establish the cause of the damage by Rolls Royce are continuing, fully supported by the RB Engineering team.
At the same time, RB has been in consultations with Brunei Department of Civil Aviation (DCA) concerning the flight safety and technical aspects of this incident. Following this consultation and in the interests of passenger safety, which is our primary concern above all other matters, a boroscope inspection will now be conducted for all Rolls Royce Trent 1000 engines on the remaining three Boeing 787-8 aircraft operated by RB.
Of necessity, this inspection process will cause very severe disruption to RB scheduled services for the next number of days.
Deputy Chairman, Dermot Mannion commented: ‘We extend our sincere apologies to our loyal passengers for this disruption to their travel plans. However, we know our passengers will appreciate the safety reasons for which this difficult decision has had to be taken. Please rest assured that RB is working with Rolls Royce and Boeing, at the very highest level, to return our aircraft to normal operations, as quickly as possible.’

Health monitoring is usually not real-time, but based on data blocks provided once per flight; though there may be more than one block/transmission.
Interesting phrase in the press quotation above
- which might be normal maintenance SOPS, or perhaps related to specific advice...
The latter indicates positive usage of health monitoring systems.

There is an EASA AD (No.: 2013-0308) that requires repetitive inspections and/or modification of the Intermediate Pressure Turbine Blades. Anybody know if the damage was found to be in the IPT on these engines?

The boroscope inspection
I guess I kludged past this at first..
What is a boroscope?
I have heard of a borescope, and was wondering how this would find damage to blades..looking up boroscope, I see no reference to this term...
Arent blades ultrasonically tested?
Whichever way you spell it (either is correct), it's perfectly possible to detect damage to blades and guide vanes with one.

Contact Approach, I am not sure you can attach any blame to Boeing in this instance. This is clearly an engine problem. The Trent 1000 has proved very reliable in service. To find 2 engines on the same aircraft with the same damage one of which failed in flight must be worrying. Either there is an inherent fault or there is an issue with maintenance procedures in a specific organisation. These will not be the highest time Trents either, ANA has been operating the B787 for longer with the same engines.
Has there been a worldwide AD or SB to reinspect all of these engines? Was damage found in the IPT?
In 2013 EASA issued an airworthiness directive after rear seal fins were found missing on some intermediate-pressure turbine (IPT) blades during on-wing inspections and overhaul.
The agency says that “release of an IPT blade rear seal fin may result in downstream, secondary damage, potentially accompanied with engine power loss.” The AD becomes effective on May 2.
EASA orders on-wing borescope inspections—after the first 450 cycles at the latest—that will have to be repeated every 200 cycles. The borescope inspection is also to be performed during engine shop visits. If two or more rear seal fins are found broken or missing, or damage on the rear of a blade or the front of a Stage 1 low-pressure turbine blade has been found and the damage is outside defined limits, the engine has to be removed. This type of blade can still be installed in engines if they are checked as defined by the AD.
I am guessing that for the average operator this would need to be done every 80-100 days = 200 cycles?
I believe the later engines are modified.
