SINGAPORE - Sparks were seen flying from one of the engines of a Scoot passenger plane returning to Singapore from Sydney on Saturday (Nov 26).

According to Shin Min Daily News, passengers on flight TZ001 first heard a loud sound from the Boeing 787 Dreamliner before they noticed sparks from the engine on the plane's right wing.

A passenger's friend described the incident in a post on social media with an accompanying video.

In response to media queries, Scoot told The Straits Times on Monday (Nov 28) that the incident took place during the plane's descent to Singapore. This "necessitated a shut-down of the right engine".

Its flight crew then contacted the Singapore Air Traffic Control Centre and requested fire services to be on stand-by upon landing.

Scoot said that the aircraft landed as scheduled and fire services subsequently confirmed that there was no engine fire.

Its spokesman said: "The cause of the incident is currently under investigation. Safety is of utmost importance to Scoot and we will spare no effort to ensure the well-being of our guests."
