IndiGo’s engine nightmare: 3 in-air failures, 69 replacements in 18 months

India’s largest airline IndiGo, which flies four out of every 10 Indians, has had to replace Pratt & Whitney engines on its 32 A320 Neo aircraft at least 69 times in the period May 2016-November 2017. This is an astonishingly high number that raises a question mark over passenger safety in Indian skies. On an average, a fleet of 100 aircraft requires about 40 such engine changes/replacements in a 3-year period.

IndiGo says these are related to non-detection of chip, carbon seal lining or combustor chamber lining in Pratt & Whitney 1100 series engines. The airline calls these engine ‘glitches’ and ‘non-safety’ issues. Indigo’s boroscopic tests (which are used to test defects or imperfections through visual inspection by a boroscope of aircraft engines and gas turbines, etc) detected these anomalies in 69 instances. As per practice, the defective engines were replaced with other engines. Such engine replacement is typically done overnight. After the replacement, the defective engine is sent to the manufacturer to fix the problem. The planes continue to operate with the replaced engines.

However, that’s the least of IndiGo’s problems as it has had graver issues to deal with. Over the past 18 months, IndiGo has had three instances of one of the two engines of the aircraft shutting down. The aircraft landed safely powered by the second engine. Those engines have been replaced and the aircraft are back in the air.

Over the past 2 days, however, its Pratt & Whitney PW4500 series engines have reported issues related to vibration. However, the manufacturer advised all airlines around the world to ground such planes which have both PW4500 series engines. Indigo had 3 such planes out of the 11 such planes worldwide. These planes are grounded and one of the PW4500 engines is being replaced in each of these aircraft.

IndiGo has been struggling with the Pratt & Whitney engines in the newest A320 Neo aircraft ever since they were first inducted in February, 2016. Greg Hayes, chairman of Pratt & Whitney’s parent UTC, responded to the issue in the post-earnings call in September, saying the company remains, “on track to certify a combustor upgrade to incorporate into new engines.”

Yet, it is the continuing problems with the engines that raise concerns regarding passenger safety in Indian skies. Especially, when it comes to India’s biggest airline.

India remains fastest growing domestic aviation market in 2017: IATA

India remained the world’s fastest growing domestic aviation market for the third straight year in 2017 as economic and network expansion bolstered the sector, according to global airlines’ body International Air Transport Association (IATA).

Globally, Revenue Passenger Kilometres (RPKs) — a measure of passenger volumes — rose by 7.6 per cent in 2017, registering “above-trend growth” that was ahead of the ten- year average rate of 5.5 per cent.

“The domestic India market posted the fastest full-year growth rate for the third year in a row (17.5 per cent), followed by China (13.3 per cent),” IATA said in a report released last week.

The grouping noted that such growth rates were driven mainly by the comparatively strong rates of economic expansion seen in each country, as well as stimulus from additional airport pairs being offered.

Such new services translate into time savings for passengers and have a similar stimulatory impact on demand as cuts in airfares, it added.

“India posted the fastest domestic RPK growth for the third year in a row, driven by economic and network expansion,” the report said.

In December also, India registered the highest growth rate of 17.4 per cent.

Many Indian carriers have embarked on ambitious expansion plans and local airlines have placed orders for over 900 aircraft.

Since late 2014, lower airfares have helped in boosting passenger growth — which in 2017 was also supported by broad-based pick-up in global economic conditions.

This year, IATA said that full-year RPK growth is expected to slightly slower than recorded in 2017.

“This is mainly because increases in airline input costs – notably fuel prices but also labour costs in certain countries – mean that we are unlikely to see the same degree of demand stimulation from lower airfares in 2018 than we have in recent years,” the grouping said.

IATA represents some 280 airlines comprising 83 per cent of global air traffic.

Jet cockpit fight: DGCA suspends flying licence of both pilots for five years

New Delhi:  The two pilots who fought in the cockpit of a Jet Airways London-Mumbai flight of January 1 will no longer be able to operate as pilots for any airline for five years. In an unprecedented action, the Directorate General of Civil Aviation (DGCA) has suspended their flying licences for five years for endangering safety. The cockpit was left unmanned more than once during the fight when the co-pilot went out to bring back the lady commander who was sobbing in the galley and possibly afraid of going back to fly with him.

“DGCA has investigated the occurrence. Keeping in view serious safety lapses endangering the safety of aircraft operations, DGCA has suspended the privileges of license of the both the involved pilots for a period of five years,” DGCA chief B S Bhullar told.

The aircraft on which the fight was witnessed had 324 passenegers and 14 crew members.The regulatory action comes a fortnight after Jet sacked these two pilots. Now with the DGCA suspending their Commercial Pilot Licence (CPL) for five years, they cannot even get a job as pilots in any other airline.

Flight 9W 119 of January 1 was operated by two commanders. Jet’s senior most Boeing 777 commander was flying as co-pilot and his deputy was the commander of this flight. The “co-pilot” had allegedly slapped the lady commander and then the cockpit was left unmanned on two occasions when he went out to bring her back in. Soon after the incident was reported, the DGCA had suspended the co-pilot’s flying licence. Later Jet had sacked the pilots.

For in-flight Wi-Fi, airlines likely to charge 30{f32dc76102757d19df9131cdc28115d9989856b4a44e5e08e1d600a023141750} of fare

  • Officials said the charges for net connection might range from Rs 500 to Rs 1,000 for thirty minutes to an hour as per international standards
  • Airlines have to pay service providers like Inmarsat and others a hefty sum to activate in-flight net connectivity

CHENNAI: Travellers could soon be able to post a selfie on social media while on board a plane, but may have to shell out at least 20-30{f32dc76102757d19df9131cdc28115d9989856b4a44e5e08e1d600a023141750} of the fare to avail of in-flight data connectivity.

Airlines are considering options to introduce the facility following a Trai order permitting in-flight voice and data connectivity+ . The move may help airlines add value to services for business class travellers on domestic and international routes. It may not be an option for low-cost carriers.

Officials said the charges for in-flight net connectivity would range from Rs 500 to Rs 1,000 for thirty minutes to an hour, according to international standards and taking into account the charges levied by service providers for slots on satellites. Airlines have to pay service providers like Inmarsat and others a hefty sum to activate inflight net connectivity.

With advance booking fares starting from Rs 1,200 to Rs 2,500 on short domestic routes, in-flight internet connectivity may be too expensive for passengers and airlines in the domestic sector.
An airline official said that Trai’s order permitting in-flight net connection would be an advantage for flights that traverse the peninsula on intercontinental routes. These flights do not have to switch off the Wi-Fi when in Indian airspace, he added.

“We are discussing the feasibility of having the facility on domestic flights. The cost and demand may have to be factored in before taking a decision,” said an official of a private airline. Airlines will have to install antennae on planes based on how they decide to receive and send the signals, either over mobile towers on the ground or over satellites.

Frequent travellers say that except for a handful of business travellers, there are no takers for in-flight internet even on international routes.

Air Passengers Association of India national president D Sudhakara Reddy said, “The in-flight data connectivity may be useful on longhaul flights. But I have hardly seen anyone use it or ask for it on international routes. It may be good during an emergency. Going by the international experience of passengers, it may not be viable for low-cost carriers.”

Some airlines allow passengers to use Wi-Fi free of charge for WhatsApp and other messenger services which may not need much bandwidth. Lufthansa, Emirates, British Airways and Delta are among the airlines that offer the service on international routes.
