Airbus A320neo hit by hydraulic system problems
Published in Amwal Al Ghad on 26 - 04 - 2016

Airbus (AIR.PA) is facing a new batch of technical problems with some of its new A320neo medium-haul jets on top of previously reported engine glitches that caused delivery delays, industry sources said on Monday.
The problems are related to the hydraulic systems and particularly an increased noise when taxiing, they said, adding that some jets are also displaying excess hydraulic temperatures, which can be a nuisance in hot climates.
Speaking separately in Dubai, Qatar Airways Chief Executive Akbar Al Baker said the aircraft had issues "with the hydraulic system and the software".
Airbus reiterated that any glitches would be resolved by July.
Regular flyers are familiar with the distinctive "dog bark" sound heard below the cabin in some Airbus jets before take-off.
The sound is produced by a pump designed to maintain equal pressure in separate hydraulic systems, even when one of the engines supporting them is shut down.
It is a safety feature designed to ensure there is enough hydraulic pressure to retract the landing gear quickly in the event that one engine fails on take-off -- something needed to reduce drag and allow the pilot to execute a smooth recovery.
But the sound is particularly noticeable when the aircraft is taxiing on one engine, which many airlines do to save fuel.
In some of the new A320neo aircraft, that sound is more noticeable and it is feared this could be disturbing to passengers, said two people familiar with the matter.
A source close to Indian budget carrier IndiGo said noise was not a problem and the airline continued to take deliveries.
Until now, publicity surrounding A320neo deliveries has focused on problems with engines made by Pratt & Whitney (UTX.N). Close to two dozen revamped A320neo jets are awaiting delivery at Airbus's European plants.
The A320neo is also offered with LEAP engines from General Electric-Safran (GE.N)(SAF.PA) venture CFM International.
In a separate development, two industry sources said a key part in the LEAP engine -- the low-pressure compressor or "booster" -- is being modified after a problem in testing. Routine changes in engine architecture at this stage of development are considered relatively rare, they said.
A CFM spokeswoman denied there are any problems and said the changes are to improve durability by allowing more flying time between major overhauls. The changes will not affect targets of 15 percent lower fuel consumption, she added.
On Tuesday, Safran said in its first-quarter earnings statement that testing was proceeding "flawlessly".
The first CFM-powered Airbus A320neo will enter service in July with Turkey's Pegasus Airlines, industry sources said.
The redesigned engine part will be included from the outset in Boeing 737 MAX jets due to enter service in 2017 and may be retrofitted during scheduled overhauls for early Airbus users.
