EASA issued (22-Nov-2010) an Emergency Airworthiness Directive (EAD), superseding the 11-Nov-2010 directive issued following the Rolls-Royce Trent 900 engine incident involving a Qantas A380. EASA investigation results show the need to amend the inspection procedures required by the initial EAD, retaining the inspection of the air buffer cavity and focusing on the oil service tubes within the high pressure and intermediary pressure structure. This EASA directive still makes it mandatory for airlines operating Airbus A380 aircraft equipped with Trent 900 engines to perform repetitive inspections, the first within a maximum of 10 flights, then at intervals not exceeding 20 flights. If any discrepancy is found following these inspections, further engine operation shall be prohibited. The requirements of this EAD are considered interim action as the investigation led by the Australian Transport Safety Bureau is yet to deliver its final conclusions. The incident investigation continues. [more]

Bombardier C Series: record orders in 2016 as both variants finally enter service
The first commercial flight of the Bombardier CS300 on 14-Dec-2016, operated by airBaltic from Riga to Amsterdam, will be a major milestone for the Canadian manufacturer's new C Series aircraft programme. Three CS100 aircraft are already in service with SWISS, so the airBaltic flight will mean that both variants of the C Series are finally in commercial operation.
The programme is Bombardier's first wholly new aircraft development, aimed at the 100 to 150-seat market segment and offering advantages of fuel efficiency, cabin space, noise and emissions. Bombardier once targeted 2013 for entry into service, but has been dogged by problems and delays. In 2015, Bombardier seemed to have overstretched itself. The C Series received no new orders during the year and Bombardier was forced to seek investment from the Province of Québec to rescue the programme.
In 2016 the company has recovered to win a net 117 new orders, its highest annual total, bringing the programme total to 360. However, competition is cut-throat, with Airbus, Boeing and Embraer all having new developments of existing products in the same space as the C Series. Bombardier's breakthrough orders from Air Canada and Delta in 2016 required heavy price discounts.
Southeast Asia-US airline market Part 2: at least 7 airlines to offer US nonstop services by 2021
The deployment of new generation ultra-long-range widebody aircraft is prompting several airlines to plan new nonstop services between Southeast Asia and the continental US. New variants of the A350 have particularly emerged as a new, more efficient and popular option for Southeast Asia-US flights, with orders over the past year from three Southeast Asian flag carriers.
On 5-Sep-2016 Vietnam Airlines became the latest Southeast Asian airline to commit to new generation ultra-long-range aircraft capable of new nonstop routes – joining Philippine Airlines and Singapore Airlines. Garuda Indonesia and Thai Airways are likely to follow, resulting in four Southeast Asian airlines operating nonstop flights to the US by early next decade, compared with only one currently.
Delta Air Lines may also join United Airlines with nonstop Southeast Asia-US services. There are opportunities in the Southeast Asia-US market for nonstop routes, but competition with one-stop products will be intense. Profitability will be heavily challenged or non-existent. SIA started the trend due to strategic, not financial, imperatives. Under the charm of low fuel prices, Southeast Asian airlines risk falling into the spell of "me too" nonstop flights, just as they did with over-sized aircraft acquisitions.
