Nepal crash: Airport had no instrument landing system

19 January 2023

The newly opened airport in Nepal where a plane was trying to land when it crashed at the weekend did not have a working instrument landing system guiding aircraft to the runway, an official said.

All 72 people on the Yeti Airlines plane died.

Jagannath Niroula from Napal’s Civil Aviation Authority said Pokhara International Airport’s instrument landing system will not be working until February 26 – some 56 days after the airport began operations on January 1.

Aviation safety experts said that reflects the Himalayan country’s poor air safety record, though the cause of the accident has not been established yet.

An instrument landing system helps planes fly safely when the pilot is unable to maintain visual contact with surrounding obstacles and the ground, mainly due to weather conditions or at night.

Pilots can also fly by sight rather than relying on instruments.

Pilots say mountainous Nepal, where in-flight visibility problems are common, can be a difficult place to fly.

But conditions at the time of the crash were good, with low winds, clear skies and temperatures well above freezing.

While it is still not clear what caused the crash, some aviation experts say video taken from the ground of the plane’s last moments indicated it went into a stall, although it is unclear why.

Amit Singh, an experienced pilot and founder of India’s Safety Matters Foundation, said the lack of an instrument landing system or navigational aids could be a “contributory cause” of the crash and pointed to a “notoriously bad air safety culture in Nepal”.

“Flying in Nepal becomes challenging if you don’t have navigational aids and puts an extra workload on the pilot whenever they experience problems during a flight,” Mr Singh said.

“Lack of an instrument landing system only reaffirms that Nepal’s air safety culture is not adequate.”

Yeti Airlines said the plane’s cockpit voice recorder will be analysed locally but the flight data recorder will be sent to France.

Both were retrieved on Monday.

The twin-engine ATR 72-500 aircraft was flying from the capital, Kathmandu, to Pokhara, 125 miles to the west, when it plummeted into a gorge as it was approaching the airport.

The crash site is about one mile from the runway at an elevation of about 2,700 feet (820 metres).

The crash is Nepal’s deadliest since 1992, when a Pakistan International Airlines plane plowed into a hill as it tried to land in Kathmandu, killing all 167 people on board.

There have been 42 fatal plane crashes in Nepal since 1946, according to the Safety Matters Foundation.

A 2019 safety report from Nepal’s Civil Aviation Authority said the country’s “hostile topography” and “diverse weather patterns” were the biggest dangers to flights in the country.

The European Union (EU) has banned airlines from Nepal from flying to the 27-nation bloc since 2013, citing weak safety standards.

In 2017, the International Civil Aviation Organisation cited improvements in Nepal’s aviation sector but the EU continues to demand administrative reforms.

Prime Minister Pushpa Kamal Dahal Prachanda met with bereaved families on Thursday and asked hospital authorities to expedite the remaining post-mortem tests of some victims so their bodies can be handed over to their families.

Authorities said it was taking time to identify several badly burned bodies.
