32 Boeing 787s are AOG due to Rolls-Royce Trent issues; number will climb
April 27, 2018 © Leeham Co.: There are 32 Boeing 787s grounded because of problems with the Rolls-Royce Trent 1000-C engines and the number will rise “a bit,” LNC has confirmed.
The US Federal Aviation Administration and Europe’s EASA this month issued Airworthiness Directives that limit ETOPS to 140 or even 60 minutes from the 330 minutes certified originally.

Following the AD and inspections, the number of grounded aircraft rose from 15-20.
The limitations balloon costs on trans-ocean flights and render trans-polar flights impossible.
Engine deliveries affects Airbus 1Q2018 results
By Bjorn Fehrm
April 27, 2018, ©. Leeham News: Airbus Group presented its 1Q2018 results this morning. It’s heavily influenced by A320neo engine delivery delays.
Only 30 A320neos were delivered during Q1 out of a year total of 400. This has left Airbus with 60 A320neo gliders parked at Toulouse and Hamburg, waiting for engines.

Bjorn’s Corner: Aircraft stability, Part 3
By Bjorn Fehrm
April 27, 2018, ©. Leeham News: In the last Corner we discussed the problems with the long term stability of an aircraft. The aircraft deviates gradually in pitch, roll and in a combined yaw and roll mode if left without pilot input.
To hand fly such an aircraft on long routes is tiresome (been there, done that). For these occasions, one needs an assistant, an autopilot.

Suppliers confirm Airbus, Boeing rate hike studies to 70/mo for single-aisles
April 26, 2018, © Leeham News: Two suppliers publicly confirmed what’s been whispered for months: 
Airbus and Boeing are checking with the supply chain about taking production rates of the A320 and 737 families to 70/mo.
Representatives of Crane Aerospace and Esterline confirmed the studies at the I-90 Aerospace Corridor conference today in Spokane (WA).

Introduction
April 26, 2018, © Leeham News: Airbus Ultra Long-Range version of the A350-900 took off for the first time Monday. The aircraft will conduct a short flight test program before being painted in Singapore Airlines’ colours and handed over after the summer.
Airbus touts the A350-900URL as an aircraft which can fly ultra-long routes with flight times up to 20 hours and distances of 9,700nm. So, what so different with this aircraft to the normal A350-900? We use our performance model to show where the differences are.
Summary:
- The A350-900URL has got a higher fuel capacity to extend its range when used as an Ultra Long Range aircraft when loaded with fewer than 250 passengers.
- At the passenger counts where Singapore Airlines will operate the aircraft, the additional range is about 1,000nm.
- For normal operations, there would be no gains.
Boeing to hike 767F production; may be only first of several
April 25, 2018, © Leeham News: Buried deep within Boeing’s first quarter earnings report is a single, seemingly innocuous sentence:
“Reflecting the strength of the cargo market, we now plan to increase the production rate on the 767 program from 2.5 to 3 per month beginning in 2020.”
There is more to this than meets the eye. It portends potentially big orders and this rate increase may be only the first to come.

Is Long-Haul LCC viable? Part 4
By Bjorn Fehrm
April 24, 2018, © Leeham News: In the third article about Long-Haul LCC and if it’s a viable business, we described the operational costs for typical aircraft used by a Long-Haul LCC.
We now look at the revenue side of the equation, including how much revenue we need to cover our costs and what variations we have over the year.
AirAsia India looks to break-even, international flights
April 24, 2018, © Leeham News: AirAsia India is a newcomer to the Indian commercial aviation scene.
It began service in 2014 and, at Dec. 31, served just 17 cities with 14 Airbus A320s.
It had a 4.5% market share by the end of last year.
AirAsia Berhad holds a 49% stake in the airline. India’s Tata Sons holds 49% and the balance is held by Indian nationals which ties to Tata.
The AirAsia entities are tied to the AirAsia Group of Malaysia, the largest low-cost carrier in Southeast Asia.
Bangalore is AirAsia India’s headquarters.
Engine makers may face stiffer future ETOPS certification requirements

Introduction
April 23, 2018, © Leeham News: Even before last week’s Southwest Airlines accident raised the focus on aircraft engines, industry officials were becoming worried that problems with engines powering the Boeing 747-8, 787, 737 MAX and Airbus A320neo may lead to stricter certification standards by regulatory authorities.
There is also emerging evidence that the issues with the Rolls-Royce Trent 1000 on the 787s may negatively impact Airbus’ sales efforts with the A350. The A350 is
powered by an entirely different RR engine, the Trent XWB, which by all accounts has had a virtually trouble-free entry into service.
But it’s a Rolls-Royce engine and airlines affected by or watching RR’s response to the Trent 1000 problems are skeptical about the Trent XWB, LNC is told.
Summary
- How long will it take for the FAA and EASE to restore full ETOPS for the 787?
- Concerns emerge that regulators may be more restrictive of ETOPS for new engines powering new planes, with the Boeing 777X next up.
- Impact seen on reception of Rolls-Royce engines on Airbus A330neo and A350.
- What do the engine problems mean for the Boeing NMA?
