Bangalore: In a big relief to Hindustan
Aeronautics Limited, pilot error was found to have caused the
crash of the defence PSU`s Advance Light Helicopter (ALH)
"Dhruv" in Ecuador in October, a probe conducted in the US and
India into the mishap has revealed.
The crash during a military parade on October 28 in
the South American country, injuring two pilots, was
considered a major setback to India`s efforts to market its
indigenous helicopters overseas.
The Ecuadorian Air Force, which bought five Dhruvs
from the Bangalore-headquartered HAL, had grounded the entire
fleet till the probe it ordered into the mishap was completed.
However, the probe findings have come as a big relief
for HAL, which has identified South America as one of the key
export markets for Dhruv.
The probe revealed "over-manoeuvre of the pilot" led
to the crash. "The pilot had taken a very deep left turn.
Because he took the left turn, he went down in height and
didn`t have sufficient time to recover and hit the ground", a
senior HAL official said on condition of anonymity.
An Ecuadorian investigation team was at HAL last week,
armed with an independent probe -- conducted with the help of
flight data recorder and cockpit voice recorder -- that it had
carried out in Washington.
"They had gone to the US and did a neutral
investigation there. They didn`t tell us the results. They
came here and we did the probe. Then they (Ecuadorean team)
told us whatever they did in Washington is exactly what the
results we got here," the official said here.
HAL can`t make the probe results public because it has
a non-disclosure agreement with Ecuadorian Air Force, he said.
