The helicopter was in cruise at 3,000 ft with the autopilot engaged and at an approximate speed of 143 KIAS, 34 nm east of Aberdeen Airport, the crew were presented, almost simultaneously, with the following indications:
- WARN red light and aural gong
- MGB.P1 caption illuminating on the Central Warning Panel (CWP)
- CAUT amber light
- XMSN caption illuminating on the CWP
- M.P2 and S/B.P3 illuminated on the vehicle monitoring system (VMS)
- SHOT illuminated on the MGB control panel
- Zero indication on the main gearbox oil pressure gauge.
In addition, CHIP illuminated on the VMS and the MGB oil temperature started to increase.
The commander assumed control of the helicopter, reduced speed towards 80 KIAS, turned back towards the coast and initiated a descent. The crew activated the emergency lubrication system.
During the descent, the MGB EMLUB4 caption illuminated on the CWP, for which the associated procedure is to land immediately. The commander briefed the passengers and carried out a controlled ditching.
Out of interest, what does the 'SHOT' caption indicate?
Well done to the crew
