Dhruv crash results verified independently thru US by Ecuadorians and now they agree that it is pilot error, if this REDIFF / PTI report is true..should be good news for HAL.

SC taunts govt on Prez copter mishap
December 16, 2009 19:55 IST


The recent helicopter incident in which President Pratibha Patil [ Images ] had a narrow escape was enough for the Supreme Court to pooh-pooh government's suggestion for airlifting victims of disasters to safety.

A bench of Justices R V Raveendran and K S Radhakrishnan instead suggested that the government better adopt the Pune model of Bus Rapid Transport system to enable smooth passage for amubulances and fire tenders to rush to the tragedy sites.

"Helicopters are used for carrying VIPs. Unfortunately we have such pilots, who carrying the president, will hit the only building in the airport. Be just practical," the apex court told Additional Solicitor General Indira Jaising, who suggested that victims should be airlifted to get over the traffic snarls.

what kind of hassle is it to install the indigenously developed ejection seats for LCA, certified by martin & baker, on the HPT-32 or any of the basic trainers?

Why certified by martin baker?

Why not have SDRE type seats, SDRE made and certified?

Even better, best not to go down this oft trodden but seldom seldom successfully traversed route at all.

Don't need to make everything ourselves.

an SDRE ejection seat was already developed for the LCA, however LCA doesn't employ it perhaps more for project insurance reasons than anything to do with technology. I am talking about using this piece in trainers to keep costs down and the fleet floating

they also got the SDRE seat certified by martin & baker

I am not sure that anyone has designed ejection seats for slow trainers. Technically it should be feasible, But it would add bulk and weight to a basically light aircraft.

any details of this seat? links would help.


I am of the opinion that designing a seat and putting it through the whole testing process is too resource intensive and costly to take it to completion. You will end up taking the help of either martin baker or zveda to complete the process. It would be more cost effective to pay these two companies to design a seat for indian condition.

vasu ray ji,

HPT 32 is soon to be discarded, its turbo powered sibling is an HAL private venture existing only as a demonstrator.

IJT already has zero-zero ejection seats, model K-36LT manufactured by Zvesda.

The Kiran has the Martin Baker Mk H4HA.

The Hawks have come with their own ejection seats.

Where exactly do you see the market for SDRE ejection seats?

thanks jagan, lalmohan and chetak, don't have a link yet but I am sure I have read about the existence of a desi ejection seat.

if HPT 32 is being discarded, could it be transformed to do tasks similar to the Nishant? or rather more for doing courier jobs as a UAV flying inland?

Rahulji,

The CAG report on 2009 will only come out in 2012?, still the the present report will have details on 2006-07,right?, then there will be mentioning about causes of crashes of 2006-07....i hope to get a copy.

Contradicting news report. It states that the flight was cleared for VFR but pilots flew IFR and then we have the report prepared by the Committee headed by Pawan Hans Helicopters Limited chief S K Tyagi quoting poor visibility weather conditions .Why was VFR clearance given when the weather was bad unless this is another instance of DDM kind of reporting?

Pilot error cause of YSR helicopter crash, says probe report

NEW DELHI: The helicopter crash which claimed the life of Andhra Pradesh Chief Minister Y S R Reddy was caused by the error of pilots who lost control over the chopper and were engrossed for vital six minutes trying to locate a flight manual, the probe report said today.

The report, submitted to the government by the four- member inquiry committee, said the "probable" cause of the accident was that it "occurred due to loss of control resulting in uncontrolled descent in the terrain at a very high rate of descent due to entry into severe down draught".

The crew flew the helicopter under the instrument flying condition even though their flight plan was cleared for Visual Flight Rules (VFR), it said.

The crew noticed a snag and "was engrossed for vital six minutes before the impact in searching for the relevant checklist from the Flight Manual".

"This distracted their attention from the prevailing poor visibility weather conditions thus leading into the loss of situational awareness," the report, prepared by the Committee headed by Pawan Hans Helicopters Limited chief S K Tyagi, said.

Reddy, his special secretary P Subramaniam, Chief Security Officer ASC Weseley, and the two pilots Grp Capt S K Bhatia and Capt M S Reddy, were killed when the Bell 430 helicopter of the state government crashed in dense jungles of Nalamalla hills on September two last year.

Rediff has a more detailed report on the probable turn of events leading to the crash; More details on the investigations of the probe team in the snippet below


Link:http://news.rediff.com/report/2010/jan/20/ysr-pilots-error-led-to-ysr-chopper-crash-probe.htm

Snippet:
During the course of investigation, the probe team undertook technical analysis at the crash site for crucial evidence and also at the APACL hangar at Hyderabad to reconstruct the turn of events and the "tear-down analysis" of various helicopter components and systems.

The Cockpit Voice Recorder downloads, engine and electronic control unit were sent to the US for analysis and help sought from the helicopter and engine manufacturers, Bell Helicopters, Goodrich and Rolls Royce, among others. Canada's [ Images ] Transport Safety Board and the US National Transportation Safety Board (NTSB) also aided the probe.

The committee recorded the statements of various officials of Andhra Pradesh government and the APACL for various investigations and analysis.

The probe panel, which had officials from different wings of DGCA, also analysed technical inputs in coordination with Airports Authority of India [ Images ], IAF, the Met department, National Aeronautical Laboratories of Bangalore and Defence Metallurgical Research Laboratories, Hyderabad.

Does anyone know what would the main differences be between VFR and IFR? I means would IFR demand a particular minimum altitude or something?

^^^
The more one reads through the above statement the less sense it makes. If the pilot was already flying IFR he presumably would have all the IFR charts and checklists readily available within quick reach. Why then would it take the crew a whole six minutes to search for something in the check list and keep them so engrossed in trying to find something in it that the crew failed to even notice the "loss of control resulting in an uncontrolled descent in the terrain at a very high rate of descent due to entry into severe down draught". as per the TOI report. Looks like some cooked up reasoning to me.

IIRC In controlled airspace VFR requires minimum 1 mile visibility and 1000 ft below cloud cover. Which means if cloud ceiling is at 1000 ft your cant fly VFR. Flying into clouds is strictly prohibited under VFR. In uncontrolled airspace some of these conditions are relaxed.

One more accident - a MiG 21 this time. Pilot safe thankfully
http://timesofindia.indiatimes.com/indi ... 593107.cms

An Indian Air Force MiG-21 combat jet crashed soon after take-off from Bagdora in West Bengal on Friday but the pilot ejected to safety, an IAF spokesman said.

"The aircraft crashed around 3pm soon after take-off and the pilot, squadron leader Rahul Tiwari, ejected safely," the spokesman added.

MiG-27s grounded for checks - HT
The Indian Air Force has ‘grounded’ its fleet of over 100 MiG-27 ground attack fighters for mandatory checks following a fatal crash in West Bengal last week.

A senior IAF official said the aircraft would not be taking part in the Air Force’s biggest ever fire power display, Vayu Shakti-2010, aimed at highlighting its operational

and precision strike capabilities by day, dusk and night at the Pokhran ranges on February 28.

The IAF has lost 12 MiG-27 fighter planes since January 2001.

IAF Chief Air Chief Marshal PV Naik said the latest MiG-27 crash might have been caused by a failure of the low-pressure turbine blades.

Asked if the combat maneouvres were aimed at sending a message to Pakistan, he said, “Our demonstration is intended to tell the people of our country, the capability of the IAF, its skills and strategic reach to protect the skies and national interest.”

IAF's Dhruv helicopter crash-lands in Jaisalmer
New Delhi: An Advanced Light helicopter "Dhruv" of the Indian Air Force on Saturday crash-landed in Rajasthan's Jaisalmer district while rehearsing for the "Vayu Shakti" air power show to be held there on Sunday.

The helicopter was part of the Sarang Helicopter Display Team of the IAF and was rehearsing for tomorrow's air show, when the incident occurred, IAF officials said here.

"Both pilots are safe after they had to make a controlled crash-landing due to loss of power in the chopper," they added.

The IAF has ordered a Court of Inquiry to look into the reasons behind the incident, the officials said.

In 2005, the entire ALH Dhruv fleet had been grounded for several months after a similar incident in Andhra Pradesh and the subsequent probe had found a fault with the tail rotor blades of the choppers.

On whether the display team comprising four ALH Dhruvs will take part in the air show on Sunday, for which the President and the defence minister are also coming, they said, "Sarang's participation is not yet cancelled."

Dhruv helicopter crashlands while rehearsing for air show

On whether the display team comprising four ALH Dhruvs will take part in the air show tomorrow, for which the president and the defence minister are also coming, they said, "Sarang's participation is not yet cancelled."

This is the fifth incident involving the helicopter since 2004 when one of the choppers being operated by the Royal Nepal Army suffered a hard landing. In October 2009, an ALH Dhruv of the Ecuadorian Air Force crashed during display manoeuvres at the Mariscal Sucre International Airport there.

After the formation of Sarang team in 2003, this is the second accident involving its Hindustan Aeronautics Limited (HAL)-built Dhruv helicopters.

In the first incident on February 2, 2007, one of the choppers crashed in Bangalore killing its co-pilot during rehearsals before the Aero India show.

All the three Services along with the state governments operate the helicopter and it has been exported to various countries including Nepal, Ecuador, Mauritius, Maldives and Israel.

can someone explain what is the technology built behind for safe crash-landing? perspective: any possibility of malfunction of the logic/sensor involved in sensing a crash when it is not, and creating a safe-crash landing by taking over the controls.

^^^
All helo pilots train for loss of power scenarios. When loss of engine power happens, the idea is to lower the pitch angle of the helo blades immediately and reduce drag. All modern helos are equipped with a freewheeling unit (a.k.a. clutch mechanism) that allows the blades to rotate even if the engine is not running. In most cases, it comes on automatically if the engine speed is drastically slower than the blade speed. Since the main rotor is now disconnected from the engine, it can rotate freely and there is no effect of engine-braking to slow it down.

Thus when the helicopter is descending with no engine power, the helicopter blades still keep rotating because of the air rushing upwards through the blades (the phenomenon is called auto-rotation) and thus generate enough lift to keep the rate of descent slow enough to make a safe landing. Not always pleasant, but it is better than crashing :)

There is generally a speed vs height graph also called "the dead man's curve". Different for different aircraft obviously.

Auto rotation is possible only above this curve and never below it.

Yep, technical term is HV curve (Height Velocity Curve). As you said, it is different for different aircraft.
http://www.copters.com/pilot/hvcurve.html has a good explanation about it.

Negi ji,

During auto rotation, the blades will always rotate in the same direction as normal flight.

The range of control of the pitch of the blades will remain as during normal flight as this range is mechanically set and locked.

The pitch of the blades cannot normally be operated beyond this range. They also cannot be reversed, as you say, beyond this narrowly set range, at most it may come to a relatively small angle at the lower limits.

Auto rotation does not set in but has to be consciously induced in a deliberate manner.

There were two pilots in the aircraft. Names are out on TV. I am not putting them here now.

Seems like at least one of them ejected.

Added later. The Navy Chief says that the two pilots did not eject.
