Scoot (TR, Singapore Changi) has not so far seen any adverse effects of the technical issues related to Rolls-Royce Trent 1000 engines powering its B787-8s and B787-9s, the CEO of the LCC's parent Singapore Airlines (SQ, Singapore Changi) Goh Choon Phong said during the annual investors and media briefing in Singapore on May 18, 2018.

"Of course, we don't like the situation but its impact on us has not been very big, primarily because we work very closely with Rolls-Royce," Goh said.

He added that because the British engine manufacturer has an engineering centre in Singapore, it is easier to deal with the emerging technical issues.

It is recalled that the Rolls-Royce Trent 1000 engine powerplant has recently been plagued by technical problems, leading the regulators to impose much stricter than ordinary requirements for inspections. In March, Rolls-Royce, in conjunction with the European Aviation Safety Agency (EASA), issued an AD requiring operators of Package C Trent 1000 powerplants to carry out earlier than usual maintenance checks on a specific part of the engine compressor. This check was already required prior to the engine reaching a threshold of 2,000 cycles, although EASA later reduced that timeframe to just 300 cycles. On top of that, on April 17, the FAA restricted the ETOPS range of the affected aircraft from 330 to 140 minutes one-engine diversion time.

According to the ch-aviation fleets module, the Singaporean LCC currently operates a total of sixteen Boeing widebody twinjets equipped with the engines of the affected types: ten B787-8s with Trent 1000-G2 powerplants and six B787-9s with Trent 1000-J2 engines, although it is not clear if all of them have already reached the threshold for mandatory extraordinary inspections.

The -A2, -AE2, -C2, -CE2, -D2, -E2, -H2, -K2, and -L2 engine subtypes are also affected. Other operators whose aircraft sport these subtypes include British Airways, Thai Airways International, Air Europa, Avianca, Ethiopian Airlines, LOT Polish Airlines, Norwegian, Norwegian UK, Air New Zealand, Royal Brunei Airlines, Virgin Atlantic, and LATAM Airlines.
