FAA issued 737 MAX’s LEAP-1B engine corrosion issue
FAA issued 737 MAX’s LEAP-1B engine corrosion issue: The FAA has released a new Airworthiness Directive for some CFM LEAP-1B engines used in the 737 MAX family of aircraft. The Directive addresses corrosion caused by long-term storage of planes, which can result in reduced thrust in certain cases. The remedy is simple enough, and it does not place a huge burden on the affected airlines.
When an aircraft is parked for an extended period of time without use, it is common for certain parts to begin to display signs of wear and tear. The global 737 MAX fleet was grounded for more than two years.
According to the FAA, there have been several reports of pressure sub-system (PSS) unit faults due to corrosion after storage for some CFM LEAP-1B engines. It explicitly states,
“In April 2021, the FAA received a report from CFM, the engine manufacturer, of numerous instances of PSS unit faults. The manufacturer reported these faults have been occurring since October 2020 and are a result of pressure transducer corrosion following extended storage periods. The manufacturer’s investigation found that certain PSS units, identified by serial number, have been exposed to conditions that make pressure transducers in these units susceptible to an increased rate of faults.”
The FAA has issued a new guideline requiring airlines to conduct repeated engine tests. The US authority stated that for Leap-1B engines that were restored to service but had less than 15 hours of electrical power applied to the PSS unit within the previous 90 days, the airline should monitor the engine maintenance messages related to the pressure transducer until the unit had 15 or more hours of electrical power.
Meanwhile, the FAA needed a one-time engine review for engines that had been returned to service and had already collected 15 or more hours of electrical power to the PSS units during the previous 90 days or completed 5 flight cycles.
The same law applies to air carriers that still have Leap-1B engine-powered aircraft in long-term storage. The FAA also cautioned that if any maintenance flaws were discovered during the tests, air carriers would have to replace the PSS units.
According to the FAA’s AD, it affected 158 engines registered in the United States. This fault has nothing to do with the electrical problem that was recorded in late April.

FAA rolling out new technology at four US airports
The Federal Aviation Administration (FAA) is set to debut cutting-edge airfield surveillance systems at four prominent airports across the United States.
Austin-Bergstrom, Indianapolis, Nashville, and Dallas Love Field will spearhead the implementation of the Surface Awareness Initiative (SAI) by July 2024, marking a significant stride in runway safety enhancement efforts.
SAI revolutionizes air traffic controllers’ situational awareness by leveraging Automatic Dependent Surveillance – Broadcast (ADS-B) data. Through this innovative technology, controllers gain real-time and precise depictions of aircraft and vehicles navigating the entire airfield, irrespective of weather conditions.
Icons representing aircraft and ADS-B-equipped vehicles will populate an airport map, offering comprehensive coverage of runways, taxiways, hold ramps, and other critical areas.
This initiative is a pivotal component of the FAA’s accelerated surface safety portfolio, complementing other vital tools like Approach Runway Verification (ARV) and the Runway Incursion Device (RID). The proactive deployment of these technologies underscores the FAA’s unwavering commitment to fortifying runway safety and averting potentially hazardous incidents.
Beyond technological advancements, the FAA is taking multifaceted measures to bolster safety across the national airspace system. Initiatives include aggressive air traffic controller recruitment drives, enhancements to the Air Traffic-Collegiate Training Initiative, and the deployment of upgraded tower simulator systems in numerous facilities nationwide by the end of 2025.
Additionally, the FAA is fostering collaborative efforts through regular runway safety action team meetings and investing substantially in runway lighting and surface improvements at airports of varying sizes.

Boeing says 787 Dreamliner aircraft is safe
Boeing is standing firm on the safety and durability of its 787 Dreamliner aircraft despite mounting criticism and whistleblower allegations.
In response to concerns raised by whistleblowers and ahead of a congressional hearing, the aviation giant emphasized its rigorous testing protocols and asserted confidence in the integrity of its planes.
During a media briefing accompanied by a PowerPoint presentation, boeing aircraft
reiterated its confidence in the safety of both the 787 and 777 aircraft models. Senior engineers showcased extensive testing procedures aimed at refuting claims that approximately 1,400 Boeing planes may be afflicted by significant safety issues. The company addressed specific allegations, including concerns about gaps in manufacturing processes that could lead to premature fatigue failure over time.
The upcoming Senate hearing is expected to feature testimony from Boeing engineer Sam Salehpour, who has publicly criticized boeing airplanes safety practices and alleged retaliation for speaking out. Salehpour’s claims, currently under investigation by the FAA, include allegations of workers resorting to extreme measures during assembly, such as “jumping on pieces of the airplane” to align them.
Boeing officials stressed that thorough inspections of nearly 700 in-service Dreamliner jets revealed zero airframe fatigue findings, even after six and twelve years of heavy maintenance inspections. These results have been shared with the FAA, according to Boeing’s chief engineer, Steve Chisholm. He emphasized that the materials used in the construction of the 787 were specifically chosen for their resistance to fatigue and corrosion.
In response to Salehpour’s accusations of shortcuts in assembly processes, boeing planes
acknowledged instances where shims were not of the proper size and where areas did not meet skin-flatness specifications. However, the company dismissed claims of excessive force during assembly, stating that such practices were not part of their standard procedures.
