Delta Airlines has one of the oldest fleet of planes in the U.S. Delta is turning this into a strategic move by having to invest less in new planes and with the ability to get good flight performance from older planes with proper maintenance. Delta says it is saving about $1 billion by acquiring 49 MD-90 planes with age of about 13 years from China Southern and other global airlines, compared to the cost of buying new planes. The estimate is that it is about 10% cheaper per seat to run these planes than new 737's, when the cost of buying planes is figured in. It also took over the leases for 88 Boeing 717's with average age of 11 years from Southwest. The focus at Delta is on profitability and debt reduction by selecting routes carefully, avoiding unprofitable ones, using tight cost management. Delta is on its third year of making profits and is on plan for reducing its debt from $17 billion in 2009 to $10 billion by 2013. The older Delta fleet is also the most punctual of the large airlines in the U.S., with 86.3% of flights on time in the Jan-Sept. 2012 period. Fitch Ratings raised Delta's credit ratings to B-plus and says Delta is "the strongest player in the much improved airline industry in the U.S."...

Over the next 20 years China will need 6500 737 Max single aisle planes and 1500 Dreamliners, Boeing says. China will make up 20% of world demand. The US visit of Xi Jinping and the major efforts for good relations of president Biden through vigorous diplomacy by Blinken, Yellen and others gives Boeing an opportunity to meet this demand.

Airbus is making the Airbus 380 superjumbo model plane about 25% slower than originally planned say Airbus executives. This is partly because manufacturing is sequenced between France and Germany. The way the production system for the A380 is organized today is to split work between the French and German operations. The plane structure is built in Toulouse, France, and the cabin and interiors are fitted together in Hamburg, Germany. Tom Williams, Airbus executive vice president for programs, says this slows the completion and increases the cost. On the A330 models the work on the interior is done along the way as the structural work is being done, and this reduces cost and speeds up completion. Part of the problem is the sensitivity of the issue of moving work for unions and governments, but he now plans to push the A380 cabin outfitting back up to the earlier stage when the airplane is being built. A slower production rate means workers and engineers are learning more slowly how to build these planes efficiently by structuring tasks in a certain way and using different production methods. Boeing has also experienced similiar production delays and is working on moving up the learning curve the way EADS Airbus is doing. The A380 program has suffered delays over the years. In 2009 wiring the cabins was a problem. In 2010 a Rolls Royce engine on a A380 flight by Quantas Airways blew up on a flight after takeoff from Singapore. Because of manufacturing issues there were delays in delivery of Rolls Royce engines in 2011. Bot problems were resolved. In 2012 Airbus has found cracks in metal parts inside A380 wings which has slowed output. Airbus has delivered 77 A380 planes since 2007. The production rate is 3 A380 planes a month, compared to plans to make 4 a month by 2012. About 30 A380's are expected to be delivered in 2012, compared to 26 in 2011, 18 in 2010....

If the Federal Aviation Administration's own reviews were followed diligently by regulators the Boeing 737 Max would have become subject to new design changes much earlier. It was seen as an accident prone design in a November 2018 FAA analysis.

This report in WSJ says industry and Boeing officials now increasingly believe that workers at Boeing factory reinstalled a plug in 737 Max 9 jet but failed to put back the bolts. The door plug blew off 16000 feet over Oregon leading to an emergency landing. Boeing is affected by lack of good quality practices and worker training for quality standards for several years. The question remains why this sort of defect is not detected in the final inspection detail checklist, with a second final inspection and third for overall quality. And why the plane is not checked again for obvious defects by the airline when it receives the new plane.The cost of this is minimal compared to the cost of compensating airlines for losses in some way and loss of customer loyalty.

Development of the C919 aircraft by the Commercial Aircraft Corporation of China (Comac). The C919 would compete with the Boeing 737 and the Airbus 320. China accounts for 22% of Airbus's orders and 15% of Boeing's orders. Comac has orders for 90 C919's from state owned airlines and two leasing companies. It also has help from suppliers GE and Honeywell. Says Bob Smith, chief technology officer of Honeywell, which has 4 joint ventures with Chinese companies to supply parts for aircraft projects from flight controls to wheels and brakes: "we are not just here to build an aircraft, we are here to build an industry." Zhang Xinguo, vice president of AVIC, a state owned company helping build the plane, says the government wants to see jumbo jets, regional planes, business jets, helicopters, all made in China by Chinese companies.
