|Dhruv ALH at Aero India 2015|
Around 200 Dhruvs have been inducted into the AFs since 2001.
The helicopter, which was conceived as a multi-role helicopter, is now limited in its operational role because of excess weight and limited engine power.
The Dhruv fleet has been grounded several times due to technical snags.
The Indian Army has experienced at least 18 accidents since 2002.
According to MoD (July 2015), since the induction of the helicopter in AFs in year 2001, 08 (Eight) major accidents (write offs) have taken place, all of which, have been investigated by a Court of Inquiry as per extant instructions. Necessary modifications/upgradations have been carried out, on the basis of past experience, to cater to Defense Forces’ requirements.

- A Dhruv crashed during a military parade in Ecuador in October 2009 injuring its two Equadorian pilots. The Dhruv was one of the five helicopters sold to Ecuador in March 2009. The accident took place over Quito’s Mariscal Sucre International Airport during formation flying along with two other helicopters. The crew, who were trained in India, managed to get out of the crashed helicopter on their own and were taken to hospital.

- In November 2005, an ALH being ferried to Jharkhand crashed near Hyderabad after the tail rotor sheared off. Following the crash, the Indian Armed Forces grounded the Dhruv fleet; the crash was eventually attributed to the use of date expired resin in the composite tail rotor.
- In November 2004 an ALH delivered to the Royal Nepal Army experienced a hard landing damaging its undercarriage and landing gear.
Equadorian Air Force CrashesFour out of the 7 Dhruvs delivered to the Equadorian Air Force were involved in crashes. Two of the crashes (enumerated above) resulted in the helicopter being written off. Of the four crashes, 2 were attributed to pilot error and 2 to mechanical failure.
Design FlawsAccording to the ET, an Indian CAG report has pointed that ALH crashes have taken place due to a design flaw that leads to a loss of control when it is being rolled back from a left turn.
