Air India Completes Fuel Control Switch Inspections On Boeing 787 Planes, Finds No Issues
Air India on Wednesday completed inspections of the locking mechanism of fuel control switches (FCS) on its Boeing 787 aircraft and found no issues, an airline official said.
The move came after the Directorate General of Civil Aviation (DGCA) on Monday directed airlines to inspect the fuel switch locking systems on their Boeing 787 and 737 planes. This followed a preliminary report from the Aircraft Accident Investigation Bureau (AAIB) which indicated that the fuel switches were cut off before the Air India plane crash last month that claimed 260 lives.
'Over the weekend, our Engineering team initiated precautionary inspections on the locking mechanism of Fuel Control Switch (FCS) on all our Boeing 787 aircraft. The inspections have been completed and no issues were found," the official said, citing an internal message sent to Air India pilots.
The official also confirmed that all Boeing 787-8 aircraft in the fleet have had the Throttle Control Module (TCM) replaced as per Boeing's maintenance schedule. The FCS is a part of this module.
Fuel control switches regulate the flow of fuel to the aircraft engines. According to the AAIB's preliminary investigation report released on Saturday, fuel supply to both engines was cut off within one second of each other, causing confusion in the cockpit shortly after takeoff.
The 15-page report revealed that the fuel control switches for both engines moved from the 'run" to the 'cutoff" position within a second, leading to an immediate loss of altitude.
'In the cockpit voice recording, one of the pilots is heard asking the other why did he cut off? The other pilot responded that he did not do so," the report said.
While the AAIB referenced a Safety Alert for Operators (SAIB) issued by the US Federal Aviation Administration (FAA), it did not recommend any specific actions.
The airline has also urged pilots to stay alert and report any technical issues in the existing defect reporting system, the official added.

Advt Air India did not find defects with the fuel control switches on its Boeing 787 fleet, after completing safety checks on their locking mechanism, a senior airline official said on Wednesday."Over the weekend, our engineering team initiated precautionary inspections on the locking mechanism of fuel control switch on all our Boeing 787 aircraft. The inspections have been completed and no issues were found," Abhishek Durga Dethan, chief pilot of Air India's Boeing 787 fleet, said in a letter to pilots of the Tata Group-owned the world, Singapore Airlines, Lufthansa Korean Air , and Etihad Airways also said that similar checks done by them did not show any is not yet known whether similar checks on the Boeing 737 jets operated by Air India Express also did not find any reported in its July 15 edition citing an Air India official that the airline had started checks on the fuel control switches (FCS) on Saturday and completed them on half of its Boeing fleet so far. The checks haven't identified any defects, the official said."All our Boeing 787-8 aircraft have also undergone Throttle Control Module (TCM) replacement as per the Boeing maintenance schedule. The FCS is part of this module," the airline India further directed its relevant staff to remain vigilant and report any defect in the technical log, as per the existing reporting process.

The Aircraft Accident Investigation Bureau 's ( AAIB ) preliminary report on the Air India plane crash contains more information than most people were expecting, which is helpful, global airlines' grouping IATA on International Air Transport Association (IATA) is a grouping of around 340 airlines, including Air an event in Singapore on Wednesday, IATA Director General Willie Walsh, who is also a pilot, said aircraft accident investigators should be allowed time to conduct investigations properly and it is also important for the industry that the reports are published in a timely manner."I commend the Indian government and the AAIB for the release of the preliminary report, which I think contained more information than most people were expecting, which was helpful... I think all airlines and all aviation professionals will now await the publication of the final report, which I'm sure will go into significantly more detail," he also noted that he is very pleased that the Indian government and the AAIB issued the preliminary report on released the preliminary report into the crash of Air India's Boeing 787-8 aircraft that killed 260 people on June the report published 30 days after the accident, AAIB said the fuel switches to the engines of the aircraft were cut off within a gap of 1 second immediately after takeoff and caused confusion in the cockpit before the plane crashed into a said that while no formal recommendations were made by AAIB to Boeing or to engine manufacturer GE, some airlines have taken it upon themselves to check the fuel cutoff switches. "I think it is a sensible thing to do in the circumstances".While the initial report does not provide any conclusions, there are speculations in certain quarters that a possible pilot error could be a reason for the crash. Such a proposition has been strongly rejected by various pilot to him, the airline industry has always been very open in sharing information."We believe that any accident or any major incident that takes place needs to be investigated fully, properly, and reported so that everybody can benefit from the experience. And I think, you know, based on what little we know now, it's quite possible that, you know, a video recording in addition to the voice recording would significantly assist the investigators in conducting that investigation," he added.

Air India probe of Boeing 787 fuel control switches finds 'no issues'
MUMBAI: Air India's inspection of the locking feature on the fuel control switches of its existing Boeing 787 aircraft found no issues, an internal communication circulated within the airline said. The switches have come under scrutiny following last month's crash of an Air India jet that killed 260 people after a preliminary probe by Indian investigators found that they had flipped from run position to cutoff shortly after takeoff. India's aviation regulator earlier this week ordered the country's airlines to investigate the locking feature on the switches of several Boeing models. The order came after Boeing notified operators that the fuel switch locks on its jets were safe. But it was in line with a Special Airworthiness Information Bulletin (SAIB) issued by the US Federal Aviation Administration (FAA) in 2018, which recommended inspection of the locks to ensure they could not be moved accidentally. Air India's probe, however, found no problems with the locking mechanism. "Over the weekend, our Engineering team initiated precautionary inspections on the locking mechanism of Fuel Control Switch (FCS) on all our Boeing 787 aircraft," the airline's flight operations department said in a communication to its pilots. "The inspections have been completed and no issues were found," the communication said, noting that it had complied with the regulator's directives. It added that all of its Boeing 787-8 aircraft had also undergone "Throttle Control Module (TCM) replacement as per the Boeing maintenance schedule", adding that the FCS was part of this module. Other countries have also ordered their airlines to examine fuel switches on Boeing aircraft. Singapore found them all to be "functioning properly." "Our checks confirmed that all fuel switches on SIA (Singapore Airlines) and Scoot's Boeing 787 aircraft are functioning properly and comply with regulatory requirements," an SIA spokesperson told AFP earlier this week. The Boeing 787-8 Dreamliner that crashed last month was heading from Ahmedabad in western India to London, with the accident killing all but one of the 242 people on board as well as 19 people on the ground. In a letter to employees on Monday, Air India CEO Campbell Wilson said the investigation into the crash was ongoing and it would be unwise to jump to "premature conclusions."
