LIMA 2013: Problems persist with RMAF Cougars

Relations between Eurocopter Malaysia and the Royal Malaysian Air Force (RMAF) remain at an all-time low because of restrictions affecting the EC 725.

Gearbox problems have led to the civilian EC 225 equivalent being banned from all over water flying and to continued checks. An official told Shephard that Eurocopter were aware of the issues before the two helicopters were handed over last November, but did not advise the RMAF. Not too surprisingly, the RMAF is believed to be less than satisfied with the situation.

This has meant that the RMAF have been unable to become fully operational with the aircraft. Training and work up is being severely disrupted by having to check the engine’s gearbox every two and a half hours when the helicopter is flown for 20 minutes at 70% of its full torque capabilities.

Eurocopter and RMAF technicians then check the onboard HUMS for problems. While Eurocopter believes it has found the main root cause of the problem it will take some time to effectively end the current restrictions.

The RMAF has so far taken delivery of two of 12 EC 725s on order, with both aircraft operated by Kuantan-based 10 Squadron.

The EC 725 was first introduced in 2005 and French variants of the aircraft have been used operationally in Afghanistan.
