Air India Express Flight 812 Crashes Killing 160 Onboard

May 23, 2010 - Air India Express, Flight 812 from Dubai to Mangalore International Airport was involved in a crash at 6 AM Saturday, May 22nd.

The B737-800 aircraft accident occurred just after the aircraft landed at Mangalore in which Flight 812 overshot runway 24. There were 160 passengers and six crew members onboard. Of the passengers and crew 166 were killed and 8 hospitalized.

Air India had put into place a full Emergency Response Team referred to as the ‘Angels of Air India.’ A local Coordination Center had also been set up and Air India Flight Safety and DGCA teams had reached Mangalore.

The pilot, Captain Zlatko Glusicawith had more than 10,000 hours of flying experience, 3,75 of which were in the aircraft type, was on his landing approach to a challenging and poorly designed hilltop runway, with light pre-monsoon mist on the runway making it a greasy surface with 4 miles reported visibility.

It is believed that the pilot overshot the landing threshold and was not at his proper approach speed. A lost of runway surface needed under these conditions to stop (brake) the B737 from overshooting the runway, crashed into a concrete navigational aid called a localizer at the end of the runway. Pilot error is likely the cause.

   

 

Landing past the threshold may have been a result of a circular that was issued by the airline about two years ago to its pilots which states pilots should not touch down on the runway hard (hard landing) or exceed 1.65G. This rule was set up for passenger comfort, although the Boeing B737-800 could have withstood up to 2.5G landing.

A hard landing usually comes from a high rate of decent from final approach to landing. This meant that it is possible the crew on Flight 812 may have had to do a longer flare which would have brought them outside of the touchdown zone. Had the pilot exceeded 1.65G there is a good chance he would have been confronted by management. As a result many pilots will increase their flare before touch down to avoid a hard landing. 

 
Flight 812 took off from Calicut International Airport on Friday night landed at Dubai International Airport and then on to Mangalore International Airport Saturday morning some 9 flying hours or 4,000 plus miles. This meant the crew was very tired and may not have been at peak performance.

Mangalore
International Airport is a domestic and international airport serving the coastal city of Mangalore, India. The airport was opened in 1951. The airport is located near Bajpe, around 12 miles north-east of the city center. Several daily flights connect Bajpe with most major cities in southern and western India as well as many major cities in the Middle East.

The airport is located on top of a hill, with the runway landing approaches leading up to the extreme edges of the hill sides and thus called a table top runway. The edges of the hill dropping into the valley from a height of about 300 feet to 30 feet within a short distance of just 1,600 ft on the east side of the runway and from about 272 feet to 82 feet on the western side. The airport has two runways; 09/27 which is 5,300 feet of asphalt and runway 06/24 which is 9,515 feet of concrete.

Boeing is sending a team to provide technical assistance to the investigation at the invitation of the Indian authorities. Air India Express Flight 812 List Of Passengers And Crew.

The National Transportation Safety Board is dispatching a team of investigators to assist the government of India with its investigation of yesterday's airplane accident in Mangalore. 

NTSB Chairman Deborah A.P. Hersman has designated Senior Air Safety Investigator Joe Sedor as the U.S. Accredited Representative. The U.S. team will also include an NTSB flight operations specialist, an NTSB aircraft systems specialist, and technical advisors from the Federal Aviation Administration and Boeing.  The team is expected to arrive in Mangalore on Tuesday morning (local time). The investigation is being conducted by India's Directorate General of Civil Aviation, which will release all information on the progress of the investigation.
