Singapore Airlines Airbus loses power in-flight to both engines

By Afp

Published: 03:31 EST, 27 May 2015 | Updated: 03:32 EST, 27 May 2015

A Singapore Airlines (SIA) Airbus plane carrying 194 people temporarily lost
power to both engines on a recent flight to Shanghai, SIA confirmed
Wednesday after a flight tracker said the plane had to descend 13,000 feet (
3.96 kilometres) before normal operation was restored.

The carrier said it was investigating the May 23 incident together with
Airbus and engine manufacturer Rolls-Royce.

"We are not able to provide further information but we can confirm that the
same aircraft was used for the return flight," an airline spokesman told AFP.

In a statement, SIA said the Airbus A330-300, carrying 182 passengers and 12
crew members, "encountered bad weather at 39,000 feet about three and a
half hours after departure" from Singapore.

"Both engines experienced a temporary loss of power and the pilots followed
operational procedures to restore normal operation of the engines," it said.

"The flight continued to Shanghai and touched down uneventfully at 10:56 p.m
(1456 GMT) local time," it said.

It added that the engines "were thoroughly inspected and tested upon arrival
in Shanghai with no anomalies detected".

In a Twitter post late Tuesday, industry portal Flightradar24 said the
flight, codenamed SQ836, "lost power on both engines & 13,000 feet before
power returned".

In a subsequent post, it said the plane "lost both engines during the cruise
" while flying through a "huge storm", pinpointing an area in the South
China Sea off China's southern coast where the incident occurred.

SIA, Asia's third largest carrier by market value, currently has 29 Airbus
A330-300s in its passenger fleet.

It also has a fleet of 19 Airbus A380-800 superjumbos.

The airline, along with its subsidiaries SilkAir, Scoot, and Tiger Airways,
flies to 119 destinations across 35 countries.

Last week Airbus warned of a technical bug potentially affecting the engines
of its A400M military planes that was discovered during an internal test
after one crashed in Spain.

Greg Waldron, Asia managing editor at aviation information firm Flightglobal
, said the incident was a "very unusual occurrence" that "highlights the
requirements of rigorous pilot training."

"Generally these engines are extremely reliable and they work continuously
for 13-14 hours a day for months and years," he said.

He added that as passengers did not seem to have posted about the incident
on social media after the weekend, it indicated that they may have been
unaware of the engine problem.

"This is speculation, but from the inside of the aircraft it could have been
that the power loss was not obvious," Waldron said.

高空结冰。ice crystal icing. 和B787,B747-8上次的事是同一类现象。工业界对这
类现象所知甚少。

记得以前读过几篇关于ice crystal icing的文章,说是wing和cowling会结冰,为什么
会使发动机熄火?这个比water injection还严重吗?

发动机内部结冰,然后脱落进燃烧室。
