  1. Lots of things are possible. I mainly said to check the suction boost pump because you said the light came on. Usually engine pumps will just cause low pressure overall and maybe a low pressure light for that engine driven pump but the suction boost pump light coming on says the supply to both engine pumps was low. It could have been something as simple as an air bubble making its way through the system when the gear operated. Keep an eye out for having to service air side of accumulators often. If the air charge depletes often, it could be depleting into the hydraulic side and creating air pockets in the system. Were there any hydraulic compnent changes or hydraulic maintenance that happened before this flight? Have you bench checked the engine driven pumps?
