Re: Airbus lancia l'A350-900ULR - SQ cliente di lancio

Ecco il link per l'Emergency AD:

https://ad.easa.europa.eu/ad/2017-0154-E

Reason:

In the A350 design, the hydraulic fluid cooling system is located in the fuel tanks. Recently, an overheat failure mode of the the A350 hydraulic Engine Driven Pump (EDP) has been found. Such EDP failure may cause a fast temperature rise of the hydraulic fluid.

This condition, if not detected and corrected, combined with an inoperative Fuel Tank Inerting System (FTIS), could lead to an uncontrolled overheat of the hydraulic fluid, possibly resulting in ignition of the fuel-air mixture in the affected fuel tank.

To address this potential unsafe condition, Airbus issued a Major Event Revision of the Airbus A350 Master Minimum Equipment List (MMEL) that incorporates restrictions to avoid an uncontrolled overheat of the hydraulic system. Appendix 1 of this AD contains the list of MMEL items and related display messages that have been changed to “NO GO”.

Cathay Pacific grounds Airbus A350 fleet for inspections after engine failure incident
By André Orban

3 September 2024


Cathay Pacific has temporarily grounded its fleet of 48 Airbus A350 aircraft for inspections following an unprecedented engine component failure that forced a flight to Zurich to return to Hong Kong.
The airline has cancelled 24 return flights, affecting routes to Singapore, Bangkok, Tokyo, Taipei, and Osaka. The inspections revealed multiple aircraft requiring component replacements, leading to extended maintenance for some planes.
Cathay is coordinating with aviation authorities and manufacturers Rolls-Royce and Airbus.
The incident has also impacted Rolls-Royce’s stock, which dropped 6.47% following the news.
