India’s aviation regulator has ordered the country’s airlines to inspect fuel control switches in Boeing aeroplanes, after their reported involvement in a fatal Air India crash that killed 260 people in June.
The Directorate General of Civil Aviation (DGCA) said the order follows Indian and international airlines already starting to carry out their own checks.
It comes after the US Federal Aviation Administration said on Monday that the fuel control switches in Boeing aeroplanes are safe.
The safety of the switches has become a key point of concern after a preliminary report on the disaster found fuel to the engines of the plane involved cut off moments after take-off.
The disaster involving London-bound Flight 171, a Boeing 787 Dreamliner, was one of the worst aviation incidents globally in almost a decade.
Since the publication of the preliminary report on Saturday a number of different stakeholders, both in India and internationally have taken action and issued statements in response to it.
In its order, India’s aviation regulator has asked for checks to be carried out by 21 July, noting that “strict adherence to the timeline is essential to ensure continued airworthiness and safety of operations”.
The checks being requested are in line with a 2018 advisory by the Federal Aviation Administration (FAA), the US’s aviation authority, which was referenced in the preliminary report.
The 2018 advisory urged – but did not mandate – operators of Boeing models to inspect the locking feature of the fuel cut-off switches to ensure they could not be moved by accident.
Air India had not carried out those inspections because they were not mandatory, the AAIB said in its preliminary investigation.
The DGCA has now ordered airlines to carry out the checks and report back.
In its response to the report, the FAA said the 2018 advisory was “was based on reports that the fuel control switches were installed with the locking feature disengaged” – but added that it does not believe this makes the planes unsafe.
Separately on Monday, a group representing Indian airline pilots defended the flight’s crew.
The Indian Commercial Pilots’ Association said staff on board had “acted in line with their training and responsibilities under challenging conditions and the pilots shouldn’t be vilified based on conjecture”.
The preliminary report, published by the India Aircraft Accident Investigation Branch (AAIB) on Saturday, said the switches on Flight 171 controlling fuel flow to the jet’s engines had been moved from “run” to the “cut-off” position, hampering the thrust of the plane.
In recovered cockpit voice recordings, the report said one of the pilots can be heard asking “why did you cut off?” – to which the other pilot replied he “did not do so”.
The preliminary report states its role is “not to apportion blame or liability”.
Also on Monday, the Reuters news agency reported that South Korea was waiting to order all airlines in the country which operate Boeing jets to examine fuel switches.
