Rolls-Royce admits Trent 1000 blade issues to prolong groundings

Rolls-Royce is facing yet another stumbling block in the way of solving its intermediate pressure turbine (IPT) blade problems on the Trent 1000 engines. Having previously announced being “about to fix” the issue, the manufacturer now is pushing back the date of when grounded aircraft numbers could return to a single-digit level.

In the past two months, Rolls-Royce accelerated defective intermediate pressure turbine (IPT) blade replacements with final standard ones on a “limited number” of Package B and C engines, which has led to more engine removals, the engine manufacturer explains in a statement on September 20, 2019.

Thus, the return to “single-digit level” of Trent 1000 powered aircraft on ground is now expected to be delayed until the second quarter of 2020.

Issues related to the high pressure turbine (HPT) blade on Trent 1000 TEN engines also remain a “challenge”, according to the company. As it had previously warned, the problem caused an additional MRO load, which means that the rate of un-grounding aircraft affected by Trent 1000 problems is “likely to be slower” than previously planned.

In August 2019, upon revealing 2019 half year financial results, the manufacturer stated that the number of aircraft grounded due to Trent 1000 problems was decreasing “slightly below our original plans”.

At the time it also explained thatTrent 1000 TEN HPT problem was being managed “through proactive inspections”, while new blade design and certification was “underway”. “We have made good progress on resolving the Trent 1000 compressor issue, though regretfully, customer disruption remains,” Warren East, Chief Executive was quoted in a statement as saying.

Unusual corrosion in Trent 1000 intermediate-pressure turbine (IPT) blades was detected in early 2016. The problem results in early wear and cracking on Trent 1000 Package C engines. Two years later, in June 2018, it was discovered that the Package B was affected too. In January 2019, early wear of the high-pressure turbine (HPT) blade of Trent 1000 TEN was also detected, prompting for more inspections.

Aviation authorities critical of FAA Boeing 737 MAX certification

In the coming weeks, several world aviation authorities should submit a report on the certification of the Boeing 737 MAX. The conclusions will reportedly be critical of the way the Federal Aviation Administration (FAA) handled the approval of the aircraft.

The Joint Authorities Technical Review (JATR), a committee set up by the FAA in April 2019, regroups the EASA, aviation authorities from Australia, Brazil, Canada, China, United Arab Emirates, Indonesia, Japan, and Singapore, as well as NASA. It was tasked with reviewing the approval procedures of the Boeing 737 MAX, after suspicions of collusion between the manufacturer and the U.S. regulator emerged.

The report, which the JATR should submit in the coming weeks, is apparently critical of the FAA’s methods, particularly of the way it delegated some of the approval processes to Boeing’s engineers.

According to a source close to the matter quoted by the Wall Street Journal, the report recommends an earlier involvement of the FAA in the design of new systems, particularly when they can influence pilot response times during emergency situations.

Shortly after the crash of Ethiopian Airlines Flight 302, the Seattle Times revealed that the authority delegated some of the 737 MAX certification process to Boeing engineers, and specifically the review of the MCAS system which was blamed for two fatal 737 MAX crashes.

Discrepancies were found in the MACS report: the system is known for correcting the angle of the stabilizers by 2.5°, yet FAA documents state the maximum is only 0.6°. “The FAA believed the airplane was designed to the 0.6 limit, and that’s what the foreign regulatory authorities thought, too,” said an FAA engineer quoted by the media.

The MCAS relies on the reading of a single sensor while its potential failure was evaluated as one level below “catastrophic”, which goes against the usual FAA regulations. Preliminary inspection of the FDR data from the Flight 302 showed that “the two sensors differed by some 20 degrees not only throughout the flight but also while the airplane taxied on the ground before takeoff”.

The safety review also forgets to mention that the system can reset itself after each pilot input, ignoring the fact that it is able to repeatedly push the plane’s nose down.

The JATR report should be critical of the fact that these discrepancies did not alert the FAA, and will include new certification guideline suggestions to make sure it does not happen again.

“We will review all the recommendations and incorporate any proposal that would improve our certification activities,” an FAA spokesman told AFP. “We look forward to the publication of the JATR report when it is complete,” a Boeing spokesperson said in a statement, adding that the company continues to work with global regulators to safely return the 737 MAX to service.

On March 19, 2019, the EASA and Transport Canada had declared that they would not validate the decision of the FAA as it is custom but instead would run an independent investigation. The decision was confirmed by Patrick Ky, head of the EASA, in an audience with the European Parliament on September 3, 2019. More recently, it was reported that the Directorate General of Civil Aviation of India (DGCA) was also looking into testing and certifying the grounded 737 itself, rather than relying on the FAA‘s judgment.

Embraer delivers most popular E2 to launch operator

Embraer’s newest passenger aircraft, the E195-E2, is ready for service. The Brazilian manufacturer has made the first delivery to Irish leasing company AerCap and launch operator Azul Linhas Aéreas Brasileiras (Azul Brazilian Airlines) on September 12, 2019.

The E195-E2 is the largest of the three members of the Embraer E-Jets E2 family, hich also includes the E190-E2 and E175-E2, succeeding the original E-jets. Seating between 120 and 146 passengers (depending on configuration), the E195-E2 has three additional rows of seats, when compared to the current generation E195.

The regional jet received its type certification from three regulatory authorities: ANAC, the Brazilian Civil Aviation Agency (Agência Nacional de Aviação Civil); the FAA (U.S. Federal Aviation Administration) and EASA (European Aviation Safety Agency) in April 2019.

Azul, the global launch operator of the new jet, placed its first order for 30 E195-E2s in 2015, expanding it later to a total of 51. Besides the first aircraft, five other newcomer jets are expected to join the Brazilian airline’s fleet by the end of 2019.

When compared to Airbus A220-100, often described as directly competing aircraft, the sales of Embraer jet are strong. As of the end of Q2 2019, E195-E2 has accumulated 124 firm orders and 50 options. The regional jet by Airbus, which entered service three years ago, had only 90 orders as of August 31, 2019.

The E195-E2 is also the more popular of the two certified E2 family variants that already have type certification. The E190-E2, in service since April 2018, has 44 firm orders and 61 optional.

EASA to flight test 737 MAX individually; strips FAA delegation

While Boeing prepares for the un-grounding of the MAX, the aviation agencies are also doing their homework ahead of the eventual green light for the 737 MAX to fly again. However, one of the agencies is going to approve the MAX themselves, rather than delegating the Federal Aviation Agency (FAA) to do so.

European Union Aviation Safety Agency’s (EASA) executive director, Patrick Ky, “exchanged views” before the European Parliament’s Committee on Transport and Tourism, which was just newly elected in May 2019. Ky shortly presented EASA’s role in the industry and of course, touched a very important topic – the Boeing 737 MAX and the type’s return to service.

During the presentation, Ky officially confirmed that the EASA will individually approve the MAX to fly only after Boeing has met four critical conditions. Firstly, the agency “insisted that any change proposed by Boeing on the resolution of these problems would need to be EASA approved”. Secondly, as the European Union and the United States have an agreement on air safety, the FAA approved parts that the EASA did not oversee. Thus, as the MAX re-enters service, the European agency will do a “broader review of the design of the critical safety systems on the MAX”, which the EASA delegated the FAA to certify back when the aircraft was approved for service in 2017 – a topic, “not very popular with our American colleagues”, according to Ky.

Thirdly, the EASA will have to have “a complete understanding of the two accidents” and finally, it will require that “flight crews are adequately trained” regarding the changes that Boeing made to the 737 MAX software. EASA’s executive director also noted that the agency is in “regular and in very strong contact” with the manufacturer and the FAA, as every party involved is trying to get the jet back up in the air.

Meanwhile, the FAA expects to conduct certification flights with the grounded jet in October 2019, as reported by the Seattle Times. Boeing stated that the company “assumes” that the 737 MAX will return to service “early in the fourth quarter 2019”. However, during his presentation, Ky noted that Boeing has not implemented changes that would provide “appropriate response to Angle Of Attack integrity issues”, questioning whether the assumption will come to fruition. MAX operators share the skepticism, as they look forward to for flights to resume in January 2020.

The changes to certification show how much the crisis has shaken up the industry, creating a rift between agencies. A recent example of how the agencies still worked together could be the Boeing 787 Dreamliner groundings back in 2013 when the aviation authorities grounded the type worldwide due to issues with batteries and electronic systems. The EASA followed the FAA’s directive and noted that the agency is “working closely with the FAA as the primary certification authority”.

But when the second 737 MAX suffered a fatal accident, the FAA was not seen as the “primary” agency anymore – Civil Aviation Administration of China (CAAC) was, as it was the first aviation authority to ground the MAX. In contrast, the FAA had “not been provided data to draw any conclusions or take any actions”.

Two days later, the FAA joined the rest of the agencies and banned the narrow-body from operating commercial flights, one of the last agencies to do so. And, as Boeing aims to return the newest 737 family member to service as soon as possible, it seems like the FAA has lost its status as a leading agency, adding further complexity to the last chapter of the 737 MAX crisis.

Boeing: 777X “exploding doors” issue not to affect test schedule

Boeing expects the “exploding door incident” to have no significant impact on the 777X design. The incident is unlikely to affect the overall test program schedule of the new widebody jet, the planemaker said in a statement on September 10, 2019.

The incident took place during the final structural testing of the 777X static test airplane at Boeing’s plant in Everett, Washington, on September 5, 2019, according to The Seattle Times, which first reported the incident. Subject to a high-pressure stress test on the ground, the cargo door of the airplane failed – exploding outward.

Without confirming or denying the “exploding doors” fact, Being now explains that the issue involved a depressurization of the aft fuselage. It occurred not only during the final test for the static test article, but also during the final minutes of the test, at around 99% of the final test loads. The 777X was undergoing static testing since June 2019.

While the manufacturer is now trying to determine what caused it, it claims that it will not have a drastic effect on the 777X testing program. “While our root cause assessment continues, at this time we do not expect that this will have a significant impact on aircraft design or on our overall test program schedule,” according to the statement.

The 777X program has already taken several hits related to issues with the General Electric GE9X engine. While officially denying that 737 MAX grounding has affected 777X program, Boeing has also reportedly pushed back the entry into service of a smaller 777X variant, the 777-8.

Boeing 777X program takes another hit, door blows out during test

Boeing’s new wide-body jet program, the 777X, has taken another hit. Reports indicate that the manufacturer has had to suspend load tests of the new model after the cargo door of the airplane exploded outward during a recent ground stress test.

According to a report by The Seattle Times, the incident took place during the final structural testing of the 777X static test airplane at Boeing’s plant in Everett, Washington, on September 5, 2019. Subject to a high-pressure stress test on the ground, the cargo door of the airplane failed – exploding outward.

“During final load testing on the 777X static test airplane, the team encountered an issue that required suspension of the test,” Boeing spokesperson Paul Bergman said in a statement, as quoted by The Seattle Times.

The cargo door failure occurred during the final testing in 777X’s certification process by the Federal Aviation Administration (FAA), the newspaper writes. Boeing stated it is reviewing the incident to find out what exactly happened during the test.

Static test airplanes are built for ground testing only and are not intended to be flown or enter commercial service. Flight testing is a whole new ball game.

The 777X program has already taken a hard hit from issues with the General Electric GE9X engine. In June 2019, pre-delivery testing glitches detected on the new GE9X necessitated fixes that are now expected to push back first flight and delivery of the 777X, the 777-9 variant, into 2020.

A fresh and disappointing delay was also announced in August 2019, when Boeing, strained by the ongoing 737 MAX crisis, pushed back the entry into service of its smaller, ultra-long-range variant of the 777X, the 777-8, Reuters reported at the time.

Airbus deliveries fall to 42 aircraft per month in August 2019

Within the first eight months of the year, Airbus has delivered 66 more commercial aircraft than during the same period in 2018. In the first eight months of 2019, Airbus has delivered 500 commercial aircraft. But with the yearly delivery target set between 880 to 890, the effort seems to fall short of the goal.

To reach its goal, Airbus has four months and 380-390 aircraft to be delivered, which translates to approximately 96 aircraft per month. While in some months this year the company was rather close to the target (with delivery rate of 70+ planes/month and even 81 in May), the setbacks in others but the average rate at 62 aircraft per month.

Two months ago, presenting the first six months results, Airbus addressed delivery challenges, admitting that: “The second half of the year in terms of deliveries and in particular free cash flow continues to be challenging”. And challenging they so far are.

August was the second worst month this year in terms of deliveries. While in July the manufacturer delivered 69 aircraft, the rate fell to only 42 in August. In total, customers took three A220s, five A350XWBs, six A330-900s and 28 A320 Family aircraft.

Embraer delivers first KC-390 to the Brazilian Air Force

Embraer delivered the first KC-390 to the Brazilian Air Force (FAB) at the military base in Anapolis, in west-central Brazil.

“The incorporation of the KC-390 into the Brazilian air force is a milestone in military aviation,” said Brazilian air force commander, Lieutenant-Brigadier Antonio Carlos Moretti Bermudez in a statement.

The first KC-390 will be operated from Anapolis Air Base by the First Troop Transport. Embraer has already started the training of the FAB personnel. In 2014, the Brazilian Air Force ordered a total of 28 KC-390s with logistic support from the Brazilian manufacturer. It should progressively replace the C-130 Hercules within the FAB.

The KC-390 is a tactical transport and inflight refueling aircraft. Powered by two specially designed Pratt and Whitney V2500-E5 engines, it can carry 26 tons of cargo, including vehicles like two M113 armored personnel carriers, or a UH-60 Blackhawk helicopter. The biggest aircraft produced in Latin America, it is designed to take off and land on semi-prepared and unpaved airfields.

It has obtained the type certificate from the Brazilian Civil Aviation Authority (ANAC) in 2018. In July 2019, Portugal placed a firm order for five KC-390 transport aircraft, becoming the first international customer for the plane. Embraer has also received letters of intent from the Czech Republic (another partner in the program), as well as Argentina, Chile, and Colombia, for a total backlog of 35 aircraft.

Inside the eye of Dorian, the Hurricane Hunters [Video]

Weather services from all around the world have their eyes set on Hurricane Dorian. To predict its trajectory and intensity, a varied array of data is collected in real-time. In the United States, some of those measures are taken by planes. The daring pilots, known as Hurricane Hunters, belong to two units: the U.S. Air Force 53rd Weather Reconnaissance Squadron, and pilots from the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce.

Hurricane Dorian, a category 5 tropical cyclone with 325 km/h winds, has been dubbed the most powerful storm to ever hit the Bahamas. In order to measure its temperature, humidity, atmospheric pressure, and wind speed, satellites from NASA are not enough. Enter the specialists of the NOAA: aboard their two Lockheed WP-3D Orion (“Kermit” and “Miss Piggy”), they are able to fly directly into the eye of the hurricane for several hours and collect useful data using radiometers and probes, called “dropwindsondes”. To gather high-altitude information, the NOAA can also rely on a Gulfstream IV-SP jet.

On September 1, 2019, the NOAA released footage of the moment when the WP-3D Orion “Kermit reached the eye of Dorian.

 

 

Working in rotation with the NOAA pilots, the 53rd Weather Reconnaissance Squadron of the 403rd Wing of the Air Force Reserve Command uses a specialized aircraft, the Lockheed WC-130J “Weatherbird”. This version of Lockheed’s bestseller features a reinforced structure to withstand conditions more extreme than any warzone and a vast array of meteorological equipment.

 

While onboard one of those planes, Jordan Sun recorded eerie footage of the tranquility that reigns inside the eye of the hurricane.

The data collected by those two units, along with the satellite imagery provided by NASA allow the National Hurricane Center to publish a detailed report on Hurricane Dorian every three hours, allowing the decision-makers to anticipate.

Russian company sues Boeing to cancel MAX order

Less than a month ago, Boeing CEO thanked customers for their understanding during the MAX grounding crisis, stating that there were “no order cancellations”. Now, the situation is changing as Russian company is reportedly seeking to not only cancel MAX order, but also to get a lengthy compensation.

Avia Capital Services, aircraft leasing company subsidiary of Russian state-owned conglomerate Rostec, has 35 Boeing MAX aircraft on order. The company has filed a lawsuit in the United States claiming over $225 million from Boeing, Financial Times reports. The sum includes a $35 million deposit for the planes, as well as interest, compensation for damages and punitive damages.

AeroTime has reached out to Boeing regarding the lawsuit. However, the company’s spokesperson declined to comment, stating that that due pending litigation “we do not have any comment at this time”.

Back on August 7, 2019, Boeing Chief Executive Officer Dennis Muilenburg said that airlines remained the company’s “firm partners” despite months long MAX grounding and the perspective of receiving their future MAX orders with lengthy delays. Muilenburg also added that the U.S. plane maker “had no order cancellations”.

Boeing is currently facing multiple lawsuits, ranging from Lion Air flight JT610 and Ethiopian Air ET302 victims’ families, to 737 MAX pilots. Several airlines have also threatened to claim compensation from the manufacturer, starting with Norwegian. In fact, the company’s spokesperson Lasse Sandaker-Nielsen mentioned the idea to “send the bill” to Boeing as soon as the aircraft was grounded worldwide, on March 13, 2019.
