26 January 2020: Boeing 777X Starts Flight Test Campaign

WH001 will continue to conduct initial airworthiness, basic envelope expansion and flutter clearance testing.  Much of the testing will focus on the performance of the new 235.4-ft. span wing, of which almost 24 ft. is made up of the folding wing tip sections. The wing is Boeing’s fourth generation large composite design and incorporates a modified trailing edge variable camber system derived from the 787 as well as a maneuver load alleviation system to limit stresses on the wing and reduce structural weight. The folding tip feature, which performed as expected with rapid deployment and retraction before and after take-off, will also require a slightly greater-than-usual emphasis on ground testing. However, on landing the system is designed to automatically fold after touchdown as soon as ground speed slows below 50 kt. The folding wing tips are the first of their kind to feature on a commercial airliner and will be tested to ensure they meet a set of special certification conditions developed by the FAA. Tests will cover checks of additional safeguards to ensure against accidental retraction in flight or unlocking during take-off, as well as checking robust performance in gusting winds. Test standards for the wing tips are designed to conform with the same certification requirements as other moving surfaces such as ailerons and flaps.First deliveries of the 777-9 are expected to begin to launch customer Emirates in 2021.

25 January 2020: European Space Walking Record

Spacewalk, which lasted five hours and 55 minutes, was the last in a four-part series to extend the life of the particle physics detector that was not designed to be maintained in space. Installed on the outside of the International Space Station in 2011, the instrument out-performed its expected three-year mission time to provide researchers with invaluable data on cosmic rays that bombard Earth. When the cooling pumps for AMS-02 began to malfunction, plans were made to service the instrument in space and give it a new lease on life and science. During the first three spacewalks Luca and Drew replaced the old cooling system with a new one using a tube-tying technique known as swaging that was quite the feat to perform in space gloves. On this final spacewalk, where Drew held the lead role of EV1, the pair set out to check the tubes that connect the cooling system to the larger instrument for any leaks. When a leak was found in tube number five, Luca tightened this connection and waited around an hour before checking the tube again. Upon this second check, a leak was still present, but thankfully after retightening once more and waiting again the leak was overcome and the system was declared leak-free. In between these leak checks, the duo worked on get-ahead tasks, activities that often set the stage for future spacewalks, should the astronauts have extra time on their hands. Once all leaks were addressed, Luca and Drew wrapped things up by installing a mud flap between the new pump and vertical support beam before removing a cover known as a shower cap to expose the new radiator system. This maintenance task broke the European record for the most time spent spacewalking. He has now clocked in 33 hours and nine minutes, beating previous record holder Swedish ESA astronaut Christer Fuglesang’s 31 hours and 54 minutes.

20 January 2020: Grounding Cost  Growing for Boeing 737 MAX

A new report this month shows that Boeing faced a bill of more than $8 billion in compensation for airlines alone. In December, when Boeing announced the MAX production halt, it was estimated that customer concessions alone could reach $11.7 through the end of the first quarter of 2020. For starters, new costs such as flight simulator training already are known but have yet to be publicly explained by Boeing. It is expected that simulator training likely will add almost $5 billion to the cost of the grounding, using Southwest [Airlines] as a benchmark for the 4,543 [737 MAXs] in backlog at the third quarter of 2019 and the 385 in existing fleets, all of which were sold before the grounding. Then there are costs for carrying the inventory of roughly 400 MAXs parked by Boeing, as well as potential further changes to the 3,100-aircraft program accounting block basis.  Also, there is the ongoing delay in aircraft certification and change in production cadence could generate another $3.6 billion charge to Boeing’s earnings. Several industry analysts and consultants also believe Boeing will have to support its supply chain financially to some degree, so providers are able to ramp-up MAX production rates again as efficiently as possible. Other costs loom, too, such as final compensation to victims’ families through legal action. Similarly, shareholder lawsuits may emerge that require spending to litigate. Last but not least, there will be additional costs from taking on more debt, which Boeing is expected to do rather than cut shareholder dividends.

19 January 2020: SpaceX Crew Dragon Completed High-Altitude Abort Test

The last major milestone before a crewed flight test to the International Space Station (ISS) as early as March this year was successfully completed when a SpaceX Falcon 9 rocket lifted off from Kennedy Space Center and intentionally shut down 85 sec. later, setting the stage for a 131,000 ft., (40 km) Mach 2.2 test of a Dragon capsule launch escape system. As planned, the rocket, which included a fully fuelled second stage, tumbled and broke apart in a fireball about 9 seconds later, showering debris over the Atlantic Ocean. The Crew Dragon capsule, which ignited its eight Super Draco thrusters as soon as the booster’s engines shut down, fired for 8 sec., keeping the spacecraft more than 0.5 mi. up and away from the rocket, simulating an inflight launch abort. Upon reaching apogee 2 min. 25 sec. after launch, Dragon jettisoned its unpressurized trunk section and used its smaller Draco thrusters to reorient its heat shield for atmospheric re-entry. At 4 min, 48 sec.  after launch, at an altitude of 20,000 ft., Dragon jettisoned a panel near its nosecone, allowing mortars to fire to deploy a pair of drogue parachutes. A minute later, with Dragon about 6,500 ft above the ocean, four main parachutes, each 116 ft. in diameter, unfurled, slowing Dragon’s descent to 20-25 ft. per sec. The capsule splashed down about  20 mi. offshore completing the flight test after less than 9 min.

13 January 2020: First Airbus BelugaXL Enters Service

European Union Aviation Safety Agency (EASA) certified Airbus’s first whale-shaped oversized air transport aircraft BelugaXL.  It is based on the Airbus A330-200 freighter and it incorporates several newly developed elements, including its lowered cockpit, a highly enlarged cargo bay structure, and a modified rear and tail section. Because it is 7 meters longer and 1 meter wider than the ST version, the XL allows for 30 percent extra transport capacity and can carry two A350 XWB wings while the ST can carry only one. The aircraft’s wingspan extends 60.3 meters, overall length stretches 63.1 meters, and its height tops 18.9 meters. Airbus plans to introduce a further five BelugaXLs by 2023, providing them with much-needed extra transport capacity it needs to support the ongoing production ramp-up of its commercial aircraft programs. The company delivered 863 aircraft to 99 customers in 2019, outpacing its previous output record set in 2018 by 8 percent and marking the 17th yearly production increase in a row, according to the company. Its backlog at the end of 2019 stood at 7,482 aircraft. Like its predecessor, the BelugaST, the BelugaXL will carry complete sections of Airbus aircraft from different production sites around Europe to the final assembly lines in Toulouse, France, and Hamburg, Germany. Two Rolls-Royce Trent 700 turbofan engines suspended on under wing pylons power the aircraft, which carries a range of 2,200 nautical miles (4,074 km) and a maximum payload of 51 tonnes.

13 January 2020: Piston Seals Linked Pratt A320neo Engine Failures

IndiGo airline reported that  fractured mid-turbine frame (MTF) piston seals have been linked about half of the Pratt & Whitney PW1100G-JM engine failures that damaged low-pressure turbines (LPTs). Providing an update on the A320neo engine s operators said the repetitive check is helping identify seals with excessive wear before the they fail, meaning that a number of engines have been removed based on this inspection. The long-term fix is a more durable blade, which Pratt has developed and is installing on new engines and making available to operators for the in-service fleet.  India’s Directorate General of Civil Aviation (DGCA) has ordered India’s Go Air and Indigo to fast-track introduction of modified engines to eliminate the LPT blade-fracture risk and several other issues plaguing their A320neo fleets. In the meantime, mitigation measures are put in place, including the inspections, seals, and use of a less aggressive “alt-climb” procedure (at least a dozen engine failures to the practice) that should help in containing the engine failures on-wing. DGCA ordered in November to  IndiGo to ensure its entire fleet of PW1100G-JMs contain the modified standard by Jan. 31 following four in-flight shutdowns within a week. LPT failures leading to operational disruptions jumped in 2019, totalling 17 through July globally, including seven within India, compared to six and five, respectively, in all of 2018. The new update gives the airline until May 31, and said the number of engines it will need has climbed to 135 from 120, to account for engines removed following seal inspections “and other reasons,” DGCA said. “No aircraft with [an] unmodified engine in IndiGo’s fleet shall be allowed to fly after that,” it added. The LPT issue is one of several that has plagued PW1100G-JM operators, hitting Indian carriers particularly hard. Part of the reason is India’s demanding operating environment, which regularly exposes engines to sand, dust, and high ambient temperatures. IndiGo has 103 Pratt-powered A320neos in service and 49 on order.

8 January 2020: Ukraine International Airlines B737 Shot Down at Teheran Airport

Ukraine International Airlines (UIA) operated Boeing 737 was accidentally shoot down by missiles, killing all 176 people on board. Before the flight PS572 took off from Tehran Imam Khomeini International Airport that day, there was an Qatar Airways aircraft airborne with a further three Iranian air-companies taking off after flight PS752. The airport was fully operational and there was no suspension from Iran aviation authorities, no warnings. UIA operated five weekly services from Kiev to Tehran. PS572 on Jan. 8 used the same flight patterns like all other previous UIA flights.The crew followed instructions from the Air Traffic Control center in Tehran. It was a routine flight. Communication between cockpit and the airport continued until the very end.  Flight PS572 is UIA´s first fatal crash since the airline launched operations 27 years ago.

7 January 2020: A380 Program Moves into Operational Support - Aftermarket Phase

Early in 2019, Airbus accepted the harsh reality that the market for new A380s was too slow for production to be sustained beyond 2021. They now seem to have concluded that the second-hand market also is weaker than they thought. Thus, the program is moving to a phase where the keywords will be “dispatch reliability” and “spare parts,” rather than “new operator.” Lufthansa had just announced it would return six of its 14 A380s to Airbus in 2022 and 2023. Air France has begun retiring its A380 fleet, as they publicly criticized the aircraft’s performance, saying “This is the poorest operating aircraft in the fleet. We have enormous amounts of delays on this aircraft and this fleet has the highest rate of cancellations.” However, some of the operators (: Lufthansa and Qantas) have planned significant cabin upgrades, simultaneous with D checks. Airbus is keeping a close eye on the schedule for the first such 90-day-long overhaul. They will begin soon, as they are done every 12 years. The airframer wants the A380 D checks, a major event in an aircraft’s life—to be as smooth as possible. The outlook for the A380 leasing market is gloomy, as the  A380 market has been challenging for some time and has been aggravated by Airbus announcing the production stop earlier this year; further A380s will be withdrawn from flight operations in the coming years and this will not make it any easier, which means that investors cannot expect the high single-digit percentage returns originally projected and will have to make do with lower single digits. As of Nov. 30, 2019, Airbus had delivered 240 A380s to 15 operators. The backlog still contains 10, mainly earmarked for Emirates. One will be handed over to All Nippon Airways.
