Esto lo venia leyendo desde hace algun tiempo, no lo puse por que despues me brincaban al cuello algunos soñadores, pero esto es exactamente lo que pasa cuando somos conejillos de indias de ciertas empresas aeroespaciales, y aun quieren Tejas?? aqui algunos links(en ingles)

http://www.thehindu.com/2007/12/23/stor ... 280900.htmHAL who started deliveries of the Dhruv in January 2002, a good ten years after the prototype’s first flight and nearly twenty years after the programme was initiated, have so far manufactured and delivered around 60 of these multi utility machines to the Army, IAF, Navy and Coast Guard, and a handful to civilian customers like the ONGC and the Jharkhand government. But the copter has also been plagued by maintainability problems and poor availability of spares.
Two crashes, one during the run up to last February’s Aero India air show in Bangalore and the other, close to Karimnagar in Andhra Pradesh in November 2005 when the Dhruv was being ferried to Jharkhand, did not help the helicopter’s cause.
While the Karimnagar crash was due to the use of a date expired resin on the helicopter’s tail rotor, the Bangalore crash was attributed, by the HAL to pilot error, something the Air Force has not yet concurred with.
Faced with the criticism from the three Armed Forces’ chiefs on failures in the Dhruv’s line replacement units (LRUs), the HAL have initiated a number of steps to improve the reliability of the Dhruv, including setting up a new maintenance and overhaul division in Bangalore. The HAL was also forced for a while to stop production of the Dhruv in order to ensure that the maintenance and spares for the helicopters already delivered were brought up to the users’ acceptations.
En todo caso, desgracia con suerte, y loor a la FAE en su 89 aniversario

Vamos a ver, resulta que HAL es una empresa deficiente? y nuestra comisión técnica no tiene internet para saberlo?, vaya que lástima que tu no trabajas en la FAE.
Aqui la queja es debido a fallas en la lìnea de mantenimiento, esto es provisión de piezas y partes de respuesto. Seguramente otros fabricantes no cometen esos errores ni tienen incidentes con sus aeronaves.
Pero oh sorpresa si sucede.
Thunderbird accident report released
January 22, 2004 (by jetech) - A pilot's error caused a Thunderbirds F-16C to crash shortly after takeoff during a September airshow at Mountain Home Air Force Base, Idaho. The pilot ejected just before the aircraft impacted the ground.

En este caso fue error del piloto quien por cierto volviò a volar, ya que la USAF pareces que puedes cometer errores.
Captain Chris Stricklin has been in the Air Force since 1994 and flew with the Thunderbirds for the first season now. He has logged a total of 1,500+ flight hours and has received numerous awards. He served as a flight examiner, flight instructor and flight commander.
Cuando Airbus introdujo su famosa tecnología Fly by wire pues también causó algunos problemas con los pilotos.
Several Government officials investigating the crash of an Airbus A320 in eastern France said today that the pilot was flying dangerously low in demonstrating the new plane before an air show. They said there was currently no evidence that the plane had malfunctioned.

Pero algunos pilotos desconfiaron del bicho.
Officials of the French pilots' union - who have criticized the A320 on safety grounds for having two pilots instead of the usual three - attributed the accident to a malfunctioning of the plane's complex computer system.
Aviation experts have praised the system, which is designed to override many pilot errors. Several industry officials suggested that the pilot on Sunday may have turned off safety controls to give him greater freedom to carry out air-show maneuvers.
Christian Roger, president of the Air France section of the pilots' union, said the accident was caused by a ''technical problem.'' After the accident, the pilot, Michel Asseline, who supervised training of Air France pilots on the A320, told a rescuer that he had sought to increase power, but that the engines did not respond.

En fin con temor o nó tenemos que subirnos en los Airbus de Tame frecuentemente. Incluso en un caso mas reciente como el lamentable accidente del Air France que salió de Brasil.
PARIS (Reuters) - European planemaker Airbus has warned against speculating on the cause of an Atlantic plane crash but defended the safety record of its A330 jetliner.
An Air France A300 crashed into the Atlantic en route from Brazil to Paris on June 1, killing all 228 people on board in the world's worst aviation disaster in eight years.

Returning the verdicts, Mr Fell said: "The pilot of the helicopter was attempting a flying manoeuvre which was beyond his capabilities, or those of the Puma, or a combination of both

Helicopter crash blamed on major failure
Published: 12:00AM BST 18 Jul 2002
Air accident investigators are probing the causes of a North Sea helicopter crash feared to have killed all 11 people on board.
Major mechanical failure is thought to be the likely cause. Five bodies and some wreckage were recovered within two hours of the Sikorsky S-76 helicopter plunging into the North Sea some 30 miles off the Norfolk coast.
