December 14, 2018, ©.Leeham News: Last week we introduced a horizontal stabilizer to make our DC-9 like aircraft stable in pitch. We got a pitch moment curve which was forcing the nose down of the aircraft if there was an increase in Angle of Attack (AoA) of the aircraft. Should the angle of attack decrease from a trimmed position, the aircraft would put the nose up to correct the disturbance. The aircraft is stable in pitch.
Now we take a closer look at how such a horizontal stabilizer is made and why.
Aug. 13, 2018, © Leeham News: The bizarre theft of a Horizon Airlines Bombardier Q400 at Sea-Tac Airport Friday night by a 29-year old employee will take some time for investigators to unravel.
The employee, a ramp agent, appeared to have no other motive in mind other than a last joy ride before ending his life.
June 11, 2018, (c) Leeham News: In a change of pace, here are a number of photos gathered from recent visits to museums in the US and Canada.
The Lockheed L-1049 Constellation of the Airline History Museum in Kansas City is labeled the Super G, but it actually is an H model, delivered as a passenger/freighter. It was restored to G markings in TWA colors. The airplane was airworthy until 2007, when an engine fire prompted the museum to park the airplane. AHM hopes to restore the airplane to flying operation.
April 23, 2018, © Leeham News: Last week’s engine malfunction on a Southwest Airlines Boeing 737-700 was another in a rare, but not unknown, uncontained engine anomaly in recent years.
All recent similar failures didn’t cause a loss of life or serious injuries if the passengers were evacuated. Unfortunately, this accident caused one fatality and seven injuries.
Let’s put the context to this issue.
March 31, 2018 © Leeham News: The first Embraer E2 jet will be delivered April 4, to Norway’s Wideroe Airlines.
The E190-E2 seats 114 passengers in one-class, 29-inch pitch and 106 at 31-inch pitch, putting it at the low end of the 100-150 seat sector that is often maligned as a Bermuda Triangle for airplanes of this size.
The E190-E2 competes with the Bombardier CS100, a 110-seat airplane in one-class. Neither Airbus nor Boeing have a competing product. Each offers a larger airplane in the 125-150 sector, the A319neo and 737-7 MAX respectively. Embraer and Bombardier offer the E195-E2 and CS300 in this sub-sector.
Jan. 17, 2018, © Leeham Co.: Airbus announced a list price hike Monday of just under 2%.
Such price hikes are common. Boeing hasn’t announced whether it will raise the list prices this year, but in the past, it’s typically done so.
Airbus continues to list the A318 and A350-800 in its price list. There hasn’t been a commercial sale of the A318 in years and Airbus skipped creating a neo version of this double-shrink airplane.
Ostensibly, Airbus continues to offer the aircraft as an Airbus Corporate Jet (ACJ), but sales of this are few and far between.
Airbus also continues to list the A330-800 despite having only one customer with a small order for the airplane.
John Leahy, the chief operating officer-customers for Airbus, will retire in January after 33 years with the company. LNC’s editor, Scott Hamilton, has known Leahy for most of this time. This is the second of a series of reports derived from interviewing Leahy about his pending retirement. The first article appeared Nov. 28.

Dec. 14, 2017, © Leeham Co.: When John Leahy was promoted from his position as head of Airbus sales in North America and moved to headquarters in Toulouse,
France, to assume the world-wide position as head of sales, he had an ambitious goal to achieve 50% market share by 2000.
He had a little over five years to go from low-double digits to this lofty goal.
The Airbus executive board initially laughed at him, Leahy recalls 22 years later.
Sept. 30, 2017, © Leeham Co.: Today is the 49th anniversary of the roll-out of the Boeing 747-100.
On Nov. 7, United Airlines operates its last 747 flight. Delta Air Lines ends it 747 service this year. Afterward, there won’t be a single US operator of the passenger model.
The 747 remains in service with US cargo carriers Atlas Air, Kalitta Air, UPS and a few others. Globally, British Airways, Lufthansa and Korean Air Lines are among those flying the passenger model.
Ted Reed, one of the writers of TheStreet.com, asked me earlier this month to give some thoughts about the 747. Below is what I gave him; he excerpted some for his column in Forbes. The focus was on US operators.

The airline is today Europe’s seventh largest airline, two-thirds the size of Turkish Airlines, but having the same fast growth since 2005. We will cover Aeroflot’s journey in a series of articles, starting with the group’s history.
March 24, 2017, ©. Leeham Co: After covering the maintenance market for single-aisle engines, time has come for the engines used on wide-body aircraft. The engine maintenance for a wide-body engine is a bit different to the single-aisle engine. The difference is caused by the longer flight times for the wide-bodies. This makes the flight time wear a more dominant maintenance driver than it is for the single-aisle engines.
The changes in overhaul work caused by the difference in flight profiles and the lower number of engines in the market (compared to the single aisles) will affect how the overhaul market is structured and who are the dominant players.
