Nov. 17, 2016, © Leeham Co.: The deferral by United Airlines of 65 Boeing 737-700s announced Tuesday caused some observers to conclude this has a negative impact on the manufacturer, but this may well overlook a larger issue.
UAL is the latest “quality” airline to announce deferrals to reschedule capital expenditures or because of not needing the aircraft now.
Softening yields, particularly among US airlines, indicate over-capacity despite load factors of 85% or more, say industry observers.
While the backlogs of Boeing and Airbus remain solid today, do the actions of several major airlines indicate the leading edge of a global economy that’s beginning to soften?

Nov. 3, 2016, © Leeham Co.: Boeing may have solved its pressing problem of largely filling the production gap for the 747-8, but there is still a long way to go for the

777.
Boeing Co. CEO Dennis Muilenburg said last week the production rate for the 777 Classic may need to come down another 1-2 per month from the previously announced 5.5/mo if sales don’t pick up.
Despite a pending order for 15 from Iran Air and the perpetual sales campaigns, Muilenburg otherwise painted a picture about wide-body demand that is anything but rosy.

Oct. 31, 2016, © Leeham Co.: Last week’s order for 14 Boeing 747-8Fs and 14 options by UPS assures continuation of the program through 2020.
If options are exercised, and if previously announced deals with other customers finally are consummated, the program should continue at least well into the 2020 decade.

Introduction
October 16, 2016, ©. Leeham Co: “Scope clauses stop aircraft development.”
The words are those of Rodrigo de Souza, Marketing manager of Embraer Commercial Aircraft when we spoke at the sidelines of the recent ISTAT conference in Barcelona.
De Souza made the comment when we discussed how the new E-Jet E175-E2 would fit with US scope clauses. It doesn’t.

The problem is the limit on Maximum Take-Off Weight (MTOW).
“I can understand the other restrictions of a scope clause but not the Max Take-Off Weight restriction,” de Souza said. “It doesn’t make any sense; it just stops new and more efficient aircraft getting into the market. What relevance does it have in protecting mainline pilots from the regional operators taking over routes?”

Introduction
October 13, 2016, ©. Leeham Co: The airline engine industry is like a ticking bomb. Over the years, a business practice of selling the engines under manufacturing cost and planning to recover costs and make a profit on the aftermarket developed. This goes back decades.
The practice was fostered by fierce competition over the engine contracts for aircraft which offered alternative engines. The losses of the engine sales could be made up later by selling spare parts and services at high margins.
These “jam tomorrow” practices have several implications. The engine industry is now confronted with these and wonder how it could put itself in such a bind. How to handle these and what is the way back?
