Air India finds no issues with fuel switch locking in Boeing-787s: Official
On Monday, aviation watchdog DGCA directed airlines to inspect the fuel switch locking system in their Boeing 787 and 737 planes against the backdrop of AAIB's preliminary report stating that fuel switches were cut off before the Air India plane crash that killed 260 people last month.
"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, quoting an internal message sent to Air India pilots.
The official also said that all the Boeing 787-8 aircraft have undergone Throttle Control Module (TCM) replacement as per the Boeing maintenance schedule. FCS is part of this module.
FCS regulate the flow of fuel into the aircraft engines. In its preliminary report on the Boeing 787-8 crash released on Saturday, the Aircraft Accident Investigation Bureau (AAIB) said the fuel supply to both engines of the plane was cut off within a gap of one second, causing confusion in the cockpit soon after take off.
A 15-page preliminary investigation report into the Air India plane crash revealed fuel-control switches of the two engines moved from the "run" to the "cutoff" position, within the space of one second, leading to 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.
AAIB, which mentioned about FAA's SAIB in the report, did not suggest any recommended action.
The airline has also asked pilots to remain vigilant and report any defect in the technical log, as per the existing reporting process, the official added.

IndiGo's insurance premium likely to rise, in single digits
Mumbai: IndiGo Airlines , country's largest carrier by fleet size and market share , is likely to face a single-digit percentage increase in aviation insurance premiums when its annual cover comes up for renewal this week, people familiar with the matter said. The hike comes amid a hardening global reinsurance market following the recent fatal Air India crash in Ahmedabad, which could result in hull and liability claims exceeding $200 million. Explore courses from Top Institutes in Please select course: Select a Course Category The insurance renewal for IndiGo and SpiceJet-whose policies are up for renewal in October-is being closely watched by the industry as reinsurers raise prices in the wake of increasing global aviation losses . Reinsurers in the London market, which underwrite a large portion of Indian aviation risk, are tightening capacity and pushing up rates for both hull and liability covers. IndiGo's policy last year was led by New India Assurance , with co-insurers such as ICICI Lombard participating domestically. A large portion of the risk was ceded to overseas reinsurers, particularly in London, which continue to dominate aviation hull and liability insurance . Live Events The carrier's combined hull, spares, and liability cover carries a premium of approximately $13 -15 million, industry sources said. The total insurance value for its 437 aircraft fleet stands at around $20 billion. Each aircraft-primarily Airbus A320 and A321 models-is insured for a hull value between $30 million and $45 million. The fleet includes a few wide-body aircraft recently inducted for international operations. On the liability front, narrow-body aircraft typically carry coverage up to $750 million, while wide-body aircraft are covered for up to $1 billion. The current combined single limit (CSL) for liability stands at $1 billion, with maximum hull agreed value (MAV) at $150 million and spares at $300 million. Reinsurance costs have been rising since late 2023, but the recent Air India crash has led to further tightening, with international reinsurers becoming more cautious on risk appetite.

Statsguru: Rising engine-failure incidents cast a shadow on Indian skies
The common issues identified include failures in the High-Pressure Turbine and Gear Turbo Engine systems Jayant Pankaj Listen to This Article On July 16, an IndiGo flight was forced to make an emergency landing at the Mumbai airport following a reported engine failure. Two more similar incidents involving IndiGo took place within the same week. In the wake of the Boeing AI 171 crash, concerns over aircraft safety have intensified. However, these are not isolated cases. Flight cancellations in India, particularly those caused by technical glitches, have risen in the past four years to peak in 2023, with engine failures being a major contributing factor.

Is India's good friend cheating it over jointly developed air defense system? The friend is..., it is selling DRDO's...,
New Delhi: India and Israel have had a strong defense partnership for the last several decades. But this is the first time that questions have been raised on the intentions of the friendly country. Allegations are being made that Israel is marketing and trying to sell this air defense system alone, which it had made in collaboration with India's DRDO. What is the advanced air defense system in question? Barak-8 is an advanced air defense system. This is the same system that intercepted and shot down a Pakistani missile in the sky in Sirsa, Haryana. It has been developed jointly by India's DRDO and Israeli company Israel Aerospace Industries. According to the latest reports, Israel is now trying to sell this missile to some countries of the world by giving it a new name of 'Barak-MX'. Barak-8 was an important milestone in the strategic relations between the two countries, but Israel's attempt to sell this missile alone is going to trouble India. Why could it affect DRDO's credibility? A website named has claimed that Israel has not included the technology developed by DRDO in the export variant of Barak-8 air defense system. Especially the dual pulse rocket motor has not been included by Israel in the variant being sold. Israel's attempt to do so hurts the hard work of DRDO, its capability and the name it is building in the defense sector as it has made many weapons based on indigenous technology for India. What is the contribution of Indian entities in this project? India started this project in 2006 with Israel at an initial cost of Rs 2500 crore with an aim developing advanced air defense systems for both countries. This air defense system was designed to intercept ballistic missiles, advanced drones, cruise missiles and fighter aircraft up to the fourth generation. Major Indian defense companies including Bharat Dynamics Limited (BDL) and Bharat Electronics Limited (BEL) were involved in the production of essential parts of this system. In collaboration with Israel, India has developed an advanced air defense system, which has also proved its capability by shooting down the Pakistani ballistic missile Fateh-2 in the air. DRDO developed a special dual-pulse rocket motor for the Barak air defense system which gives the missile fired from this air defense system the ability to maintain its speed and change direction suddenly until it hits the target. Israel also got a huge defense market like India for this missile defense system. Why is Israel selling this system unilaterally under a different name? Despite this, Israel is selling this system unilaterally under the name 'Barak MX' for which it has signed a deal with Azerbaijan for 12 Barak air defense systems. In 2022, Israel had signed a deal worth $ 500 million with Morocco. The main point of contention is that the Barak air defense systems that Israel is selling do not have dual-pulse rocket motors, which have been developed by DRDO. Reportedly, Israel is talking to the United Arab Emirates (UAE) about the sale of Barak defense systems. Is Israel trying to bypass India? According to by using its propulsion system in the export model of the Barak Defense System, Israel is bypassing the help that India has provided at the technology level. Due to this, India is not getting any benefit in the global defense market. Apart from this, the situation is also not clear regarding the intellectual property and data rights related to this project, which raises questions on India's technical and economic participation. According to the report, Israel's doing this has put New Delhi into action. It is believed that if Israel tries to make partnerships on a unilateral basis, then both future strategic cooperation and trust in Israel may be affected. This may affect future defense agreements between the two countries.
